ABSTRACT

The objective of this study was to determine the scrotal thermographic profile and to verify the influence of temperature and humidity of the humid tropical climate on testicular temperature and seminal quality of Mangalarga Marchador stallions. The thermal profiles of the proximal, middle, and distal zones of the testicles and total surface temperature (TSTT) were recorded using an FLIR E60bx thermal imager. The average air temperature (°C) and relative humidity (%) were obtained 1, 5, 9, 33, and 66 days before semen collection and showed a mean value of 26.5±2.4 and 80.4±6.0 respectively. The scrotal surface temperature was close to 34°C and there was no variation with the age of the stallion, reproductive activity, and characteristics of the ejaculate (P>0.05). The only significant correlations obtained were between TSTT and minor defects (R = 0.41; P<0.05), between TSTT and total defects (R = 0.46; P<0.01), and between TSTT and percentage of morphologically normal sperm (R = -0.46; P<0.05). It was concluded that the Mangalarga Marchador stallions maintained the testicular temperature within favorable conditions for spermatogenesis, demonstrating the efficiency of testicular thermoregulation mechanisms in the Atlantic Forest biome.


O objetivo deste estudo foi determinar o perfil termográfico escrotal e verificar a influência da temperatura e da umidade do clima tropical úmido na temperatura testicular e na qualidade seminal de garanhões Mangalarga Marchador. Os perfis térmicos das zonas proximal, média e distal dos testículos e a temperatura da superfície total (TSTT) foram registrados usando-se um termovisor FLIR E60bx. A temperatura média do ar (° C) e a umidade relativa (%) foram obtidas um, cinco, nove, 33 e 66 dias antes da coleta de sêmen e apresentaram valor médio de 26,5 ± 2,4 e 80,4 ± 6,0, respectivamente. A temperatura da superfície escrotal foi próxima a 34°C, e não houve variação com a idade do garanhão, a atividade reprodutiva e as características do ejaculado (P>0,05). As únicas correlações significativas obtidas foram entre TSTT e defeitos menores (R=0,41; P<0,05), entre TSTT e defeitos totais (R=0,46; P<0,01), e entre TSTT e porcentagem de espermatozoides morfologicamente normais (R=-0,46; P<0,05). Concluiu-se que os garanhões Mangalarga Marchador mantiveram a temperatura testicular dentro de condições favoráveis para a espermatogênese, demonstrando a eficiência dos mecanismos de termorregulação testicular no bioma Mata Atlântica.

ABSTRACT

Introducción. El orquidómetro de Prader es el método estándar para medir el volumen testicular (VT) en niños y adolescentes. Objetivo. Evaluar la concordancia en la estimación del VT y del inicio puberal con las técnicas de orquidometría de Prader, Chipkevitch y Sotos. Métodos. Diseño descriptivo transversal realizado en varones de entre 9 y 20 años. Se midió el VT (ml) en cada adolescente con las técnicas de Prader (método de referencia), Chipkevitch (modelo gráfico) y Sotos (medición de ancho testicular con regla plástica y fórmula equivalente a ecuación elipsoide). Se excluyeron varones con patología urogenital y enfermedades que afectan el crecimiento testicular. Para la concordancia entre métodos, se utilizó kappa para el inicio puberal, y coeficiente de correlación intraclase (CCI) y gráficos de Bland-Altman (GBA) para el VT. Resultados. Se incluyeron 377 varones sanos. Para la concordancia en VT (ml), la comparación Prader-Chipkevitch obtuvo CCI: 0,994 y p < 0,001; y de CCI; 0,312 y p < 0,001 para la de Prader-Sotos. En los GBA se halló una media de las diferencias cercana a 0 ml en la comparación Prader-Chipkevitch y cercana a 8 ml en la de Prader-Sotos. El acuerdo en el inicio puberal obtuvo un valor de kappa 0,93 en la comparación Prader-Chipkevitch y de 0,75 en la de Prader-Sotos. Conclusión. Los orquidómetros de Prader y Chipkevitch tienen una excelente concordancia en la estimación del VT y el inicio puberal; por lo tanto, podrían intercambiarse en la atención diaria de varones adolescentes. El método de Sotos mostró una concordancia buena en la estimación del inicio puberal, pero baja en la medición del VT


Introduction. The Prader orchidometer is the standard method used to measure testicular volume (TV) in children and adolescents. Objective. To assess the concordance in the estimation of TV and puberty onset with the Prader, Chipkevitch, and Sotos orchidometric techniques. Methods. Cross-sectional descriptive study conducted among male children and adolescents aged 9-20 years. For each adolescent, TV was measured with the methods by Prader (gold standard), Chipkevitch (graphic model), and Sotos (measurement of testicular width with a plastic ruler and use of a formula equivalent to the ellipsoid equation). Male children and adolescents with urogenital conditions and disorders affecting testicular growth were excluded. Kappa statistics was used to determine concordance among methods for puberty onset, and intraclass correlation coefficient (ICC) and Bland-Altman (B&A) plots for TV. Results. In total, 377 healthy males were included. Regarding the concordance for TV (mL), the Prader-Chipkevitch comparison obtained an ICC of 0.994 and a p < 0.001; while the Prader-Soto comparison obtained an ICC of 0.312 and a p < 0.001. With the B&A plots, mean differences were close to 0 mL in the Prader-Chipkevitch comparison and close to 8 mL in the Prader-Sotos comparison. Concordance for puberty onset obtained a kappa value of 0.93 and 0.75 in the Prader-Chipkevitch and Prader-Sotos comparisons, respectively. Conclusion. The Prader and Chipkevitch orchidometers show an excellent concordance in estimating TV and puberty onset; therefore, both methods could be used interchangeably in the daily care of male adolescents. The Sotos method showed a high concordance in estimating pubertal onset, but low in measuring TV.

ABSTRACT

Non-strangulated acquired hernias in stallions are rare, especially when the herniated content is not intestinal loops. Thus, the aim of the current study is to describe a case of acquired non-strangulated inguinoscrotal hernia in a stallion, whose herniated content was the omentum. The patient was a Criollo stallion with history of rhabdomyolysis, laminitis and bilateral scrotal volume increase observed in the left scrotal region. The animal presented pain in both thoracic limbs, abnormal blood test, especially hypoproteinemia, and mild pain during palpation in the left inguinal ring region. Hydrocele secondary to hypoproteinemia was suspected. After admission, the animal showed signs of acute abdomen, which were clinically reversed. With this, the animal was subjected to ultrasound examination of the scrotal region, whose findings suggested non-strangulated inguinal hernia, although the content could not be identified. Surgical treatment was chosen in order to identify the herniated content and remove the left testicle. Access to the affected scrotum was performed, in which the presence of fluid and a portion of the omentum was observed surrounding the testis and adhering to it. The animal was discharged after he recovered from the surgery and from laminitis. During the breeding season, the stallion remained with a herd of mares for natural mating. After 15 months of surgery, the animal was reassessed and showed no active signs of inflammatory and degenerative processes in the remaining testis. On this occasion, a pregnancy diagnosis was also performed, and all the mares were pregnant. It is concluded that the presence of omentum as a herniated content does not represent a surgical emergency but can make the reproductive prognosis reserved. In addition, removal of the affected testicle can benefit the spermatogenesis of the remaining testicle.(AU)


As hérnias adquiridas não estranguladas em garanhões são raras, principalmente quando o conteúdo herniado não é de alças intestinais. Assim, o objetivo deste trabalho foi descrever um caso de hérnia inguino escrotal adquirida e não estrangulada em garanhão, cujo conteúdo herniado era composto pelo omento. Foi atendido um garanhão da raça Crioula com histórico de rabdomiólise, laminite e aumento de volume escrotal bilateral, evidenciado na região escrotal esquerda. O animal apresentava dor nos membros torácicos, alterações na avaliação sanguínea, destacando-se a hipoproteinemia, e demonstrava dor leve à palpação na região do anel inguinal esquerdo. Suspeitou-se de hidrocele secundária a hipoproteinemia. Após a internação, o animal apresentou sinais de abdômen agudo, revertidos clinicamente. Com isso, realizou-se ultrassonografia da região escrotal, cujos achados sugeriram hérnia inguinal não estrangulada, sem que o conteúdo pudesse ser identificado. Optou-se pelo tratamento cirúrgico, com o intuito de identificação do conteúdo herniado e remoção do testículo esquerdo. Foi realizado acesso à bolsa escrotal afetada, na qual se observou presença de líquido e de uma porção do omento envolvendo o testículo e aderido a ele. O animal recebeu alta após restabelecimento da cirurgia e da laminite. Na propriedade, durante temporada reprodutiva, o garanhão permaneceu com uma manada de éguas para realização de monta natural. Passados 15 meses da cirurgia, o animal foi reavaliado e não demonstrou sinais ativos de processo inflamatório e degenerativos no testículo remanescente. Nessa ocasião, também foi realizado diagnóstico de gestação e todas as éguas encontravam-se prenhes. Conclui-se que a presença de omento como conteúdo herniado não representa uma emergência cirúrgica, mas pode tornar o prognóstico reprodutivo reservado. Ainda, a remoção do testículo afetado pode trazer benefícios à espermatogênese do remanescente.(AU)

ABSTRACT

ABSTRACT Objectives: This review aims to study the role of the abdominal wall in testicular migration process during the human fetal period. Materials and Methods: We performed a descriptive review of the literature about the role of the abdominal wall in testicular migration during the human fetal period. Results: The rise in intra-abdominal pressure is a supporting factor for testicular migration. This process has two phases: the abdominal and the inguinal-scrotal stages. The passage of the testis through the inguinal canal occurs very quickly between 21 and 25 WPC. Bilateral cryptorchidism in Prune Belly syndrome is explained by the impaired contraction of the muscles of the abdominal wall; mechanical obstruction due to bladder distention and structural alteration of the inguinal canal, which hampers the passage of the testis during the inguinoscrotal stage of testicular migration. Abdominal wall defects as gastroschisis and omphaloceles are associated with undescended testes in around 30 to 40% of the cases. Conclusions: Abdominal pressure wound is an auxiliary force in testicular migration. Patients with abdominal wall defects are associated with undescendend testis in more than 30% of the cases probably due to mechanical factors; the Prune Belly Syndrome has anatomical changes in the anterior abdominal wall that hinder the increase of intra-abdominal pressure which could be the cause of cryptorchidism in this syndrome.

ABSTRACT

The morphology of the male reproductive tract of Tomodon dorsatus was described in the austral seasons of the year considering macroscopic and microscopic variables. For this purpose, 56 specimens from the herpetological collection of the "Instituto Butantan" were used. Fragments of the testes, kidneys and ductus deferens were collected and submitted to histological routine. The peak of the testicular volume was observed in the summer and the epithelium of the seminiferous tubules had higher height in the summer (p=0.001). The testes were active throughout the year, however, the spermiogenesis peaked in the summer. There were spermatozoa in the lumen of the ductus deferens in all seasons of the year. Renal length was higher in autumn (p=0.027), and renal width did not show a significant increase (p=0.237). The diameter and epithelial height of the sexual segment of the kidney (SSK) showed hypertrophy in winter and spring, coinciding with the mating period. Based on findings of this study, we can suggest that, at the population level, the reproductive cycle of T. dorsatus can be considered seasonal semi-synchronous, due to the peak of spermiogenic activity in the hot season, and discontinuous at the individual level.(AU)


A morfologia do trato reprodutivo do macho de Tomodon dorsatus foi descrita nas estações climáticas do ano com base em variáveis macroscópicas e microscópicas. Para isto, foram usados 56 espécimes oriundos da coleção herpetológica do Instituto Butantan. Fragmentos dos testículos, rins e ductos deferentes foram coletados e submetidos à rotina histológica. O volume testicular foi maior no verão e o epitélio dos túbulos seminíferos mostrou uma maior altura no verão (p=0.001). Os testículos estavam ativos durante todo o ano, contudo, a espermiogênese foi maior no verão. Espermatozoides foram encontrados no lúmen do ducto deferente em todas as estações do ano. O comprimento renal foi maior no outono (p=0.027), e a largura renal não mostrou um aumento significativo (p=0.237). O diâmetro e a altura epitelial do segmento sexual do rim (SSR) mostrou hipertrofia nas estações inverno e primavera, coincidindo com o período reprodutivo. Com base nestes resultados, pode-se sugerir que, em nível populacional, o ciclo reprodutivo de T. dorsatus possa ser considerado semi-sincrônico sazonal, devido à atividade espermiogênica na estação quente, e descontínuo em nível individual.(AU)

ABSTRACT

El síndrome de insensibilidad a andrógenos (AIS en la sigla inglesa) es una entidad muy poco frecuente en endocrinología. Se caracteriza por la mutación del receptor de andrógenos de magnitud variable, por medio del cual individuos 46,XY no se virilizan normalmente, a pesar de conservar sus testículos y tener concentraciones de testosterona en rango masculino. El cuadro clínico es variable y depende la profundidad de la alteración del receptor. En un extremo, hay casos de insensibilidad androgénica completa (CAIS) con fenotipo femenino. En el otro extremo hay insensibilidad parcial (PAIS) que se extiende desde el fenotipo femenino, con o sin ambigüedad genital, hasta los casos de hombres infértiles o con subvirilización, que presentan insensibilidad androgénica más leve. En los fenotipos femeninos, los testículos suelen estar en posición ectópica y aquellos ubicados dentro del abdomen tienen riesgo de malignizarse, por lo que suelen extirparse. Estos son los casos de más difícil manejo, pues aparte de la necesidad de gonadectomía seguida de terapia hormonal femenina, existe una vagina estrecha y en fondo de saco ciego y que suele requerir corrección quirúrgica para permitir la actividad sexual. En este trabajo presentamos 5 casos de AIS vistos recientemente en 2 centros clínicos de Santiago y que ilustran la heterogeneidad de presentación. Además, hacemos una revisión actualizada de los criterios diagnósticos, los tratamientos más adecuados y el manejo global de esta condición.


The Androgen insensitivity syndrome (AIS, in its English acronym) is a very rare entity in endocrinology. It is characterized by a variable magnitude androgen receptor mutation, whereby 46, XY individuals are not normally virilized, despite retaining their testicles and having testosterone concentrations in the male range. The clinical picture is variable and depends on the depth of the receptor alteration. At one extreme, there are cases of complete androgenic insensitivity (CAIS) with a female phenotype. At the other extreme, there is partial insensitivity (PAIS) that extends from the female phenotype, with or without genital ambiguity, to cases of infertile or undervirilized men, who have milder androgenic insensitivity. In female phenotypes, the testes are usually in an ectopic position and those located within the abdomen are at risk of malignancy, and therefore are usually removed. These are the most difficult cases to manage because apart from the need for gonadectomy followed by female hormonal therapy, there is a narrow vagina and a deep blind pouch that usually requires surgical correction to allow sexual activity. In this work, we present 5 cases of AIS recently seen in 2 clinical centers in Santiago and that illustrate the heterogeneity of presentation. In addition, we make an updated review of the diagnostic criteria, the most appropriate treatments, and the overall management of this condition.

ABSTRACT

BACKGROUND@#The industrial revolution has resulted in increased synthesis and the introduction of a variety of compounds into the environment and their potentially hazardous effects have been observed in the biota. The present study was aimed to evaluate the potential endocrine-disrupting effects of chronic exposure to the low concentrations of bisphenol S (BPS) in male rats.@*METHODS@#Weaning male Sprague-Dawley rats (22 days old) were either exposed to water containing 0.1% ethanol for control or different concentrations of BPS (0.5, 5, and 50 μg/L) in drinking water for 48 weeks in the chronic exposure study. After completion of the experimental period, animals were dissected and different parameters (hormone concentrations, histology of testis and epididymis, oxidative stress and level of antioxidant enzymes in the testis, daily sperm production (DSP), and sperm parameters) were determined.@*RESULTS@#Results of the present study showed a significant alteration in the gonadosomatic index (GSI) and relative reproductive organ weights. Oxidative stress in the testis was significantly elevated while sperm motility, daily sperm production, and the number of sperm in epididymis were reduced. Plasma testosterone, luteinizing hormone (LH), and follicle-stimulating hormone (FSH) concentrations were reduced and estradiol levels were high in the 50 μg/L-exposed group. Histological observations involved a significant reduction in the epithelial height of the testis along with disrupted spermatogenesis, an empty lumen of the seminiferous tubules, and the caput region of the epididymis.@*CONCLUSION@#These results suggest that exposure to 5 and 50 μg/L of BPS for the chronic duration started from an early age can induce structural changes in testicular tissue architecture and endocrine alterations in the male reproductive system which may lead to infertility in males.

ABSTRACT

This study aimed to assess the possible occurrence of reproductive changes in male goats associated with ingestion of Cenostigma pyramidale hay. Sixteen animals divided into two experimental groups, G1 and G2 (control group) were used. Animals in G1 received 2% of forage, based on live weight (LW), composed of 100% of C. pyramidale, and animals in G2 received 2% of Panicum maximum "Massai' grass hay, based on LW. Both groups received 1% of concentrated feed supplementation based on LW, along with mineralized salt and water ad libitum. The goats were subjected to weighing, testicular biometry, and semen and blood collection every 30 days. After 120 days, the animals were castrated and their testes were collected. Testicular measurements were performed and fragments were collected for histological processing to determine the gonadosomatic index (GSI), diameter of the seminiferous tubules, height of the germinal epithelium (HGE), volumetric proportion and volume of the testicular parenchyma components, total length of the seminiferous tubules, length of the seminiferous tubules per gram of testis, and leydigosomatic and tubulosomatic indexes. The data were evaluated for normality using the Student's t-test. Data with normal distribution were assessed using analysis of variance (ANOVA) and the non-parametric data were evaluated using the Kruskal-Wallis test, both at 5% probability. Statistically significant differences (p<0.05) were observed for GSI (G1=0.48 ±0.08 and G2=0.34 ±0.09) and HGE (G1=52.95 ±2.99 and G2=.47.63 ±2.67) between treatments. Consumption of C. pyramidale hay increased LW and, consequently, testicular weight, contributing to high GSI. In conclusion, ingestion of C. pyramidale has no toxic effect on the testicular, seminal and histological parameters of goat testis. Due to its nutritional characteristics, consumption of this plant improves animal body development. Because C. pyramidale is adapted to semi-arid regions, it can be an alternative source of feed for goats during periods of shortage.(AU)


Para avaliar a possível ocorrência de alterações reprodutivas em caprinos machos associado ao consumo de Cenostigma pyramidale, foram utilizados 16 animais divididos em dois grupos experimentais, G1 e G2 (grupo controle). Animais pertencentes ao G1 receberam 2% de volumoso, com base no peso vivo (PV), constituído de 100% de C. pyramidale e o G2 receberam 2%, com base no PV, de feno de Panicum maximum 'Massai'. Todos os grupos receberam 1%, com base no PV, de suplementação concentrada, além de sal mineralizado e água ad libitum. A cada 30 dias os animais eram submetidos à pesagem, biometria testicular e coletas de sêmen. O sêmen foi avaliado quanto ao volume, turbilhonamento, vigor, motilidade, concentração espermática, defeitos maiores, menores e totais. Após 120 dias os animais foram castrados e os testículos coletados. Foram realizadas as mensurações testiculares e coletados fragmentos para o processamento histológico, para determinação do índice gonadossomático, diâmetro dos túbulos seminíferos, altura do epitélio germinativo, proporção volumétrica e volume dos componentes do parênquima testicular, comprimento total dos túbulos seminíferos, comprimento de túbulo seminífero por grama de testículo, índices leydigossomático e tubulossomático. Os dados foram avaliados quanto à normalidade pelo teste t de Student, os dados com distribuição normal foram analisados por análise de variância com 5% de probabilidade e os não paramétricos, pelo teste de Kruskal-Wallis, a 5% de probabilidade. Houve diferenças significativas (p<0,05) para índice gonadossomático (G1=0,48±0,08 e G2=0,34±0,09) e altura do epitélio germinativo (G1=52,95±2,99 e G2=47,63±2,67) entre os tratamentos. O feno de catingueira promoveu aumento no peso corporal e consequentemente maior peso testicular, o que contribui para elevação do IGS. Concluiu-se que o consumo da C. pyramidale não possui efeito tóxico sobre os parâmetros testiculares, seminais e histológicos do testículo dos caprinos e que a planta, por suas características nutricionais promoveu melhora no desenvolvimento corporal dos animais e por ser uma planta adaptada ao clima do semiárido, se constitui uma fonte alternativa de alimentação para esta categoria animal, durante períodos de escassez de alimento.(AU)

ABSTRACT

SUMMARY: The study reported the influence of the high and acute dose of Letrozole on the testis morphology in paca (Cuniculus paca), an aromatase inhibitor that reduces the endogenous estrogen, the essential hormone for spermatogenesis. Morphological changes were observed in seminiferous epithelium with germ cells with apoptotic characteristics and presence of vacuoles and nuclei in pycnose.


RESUMEN: El objetivo de este estudio fue analizar la influencia de una dosis alta de Letrozol en la morfología de los testículos de la paca (Cuniculus paca), un inhibidor de la aromatasa que reduce el estrógeno endógeno, la hormona esencial para la espermatogénesis. Se observaron cambios morfológicos en el epitelio seminífero con células germinales con características apoptóticas y la presencia de vacuolas y núcleos en picnosis.

ABSTRACT

SUMMARY: Bisphenol A (BPA) is an industrial chemical widely used to make polycarbonate plastics for packaging and epoxy resins. This study sought to examine how selenium (Se) affects BPA toxicity in terms of albino rats' histological structure, antioxidant enzymes and reproductive organs (seminiferous tubules). Twenty-four adult male rats were divided into four experimental groups: Group 1: Control; Group 2: Orally administered BPA; Group 3: Orally administered sodium selenite; Group 4: Treated daily with BPA followed by selenium (Se). All experiment done for 4 weeks. BPA exposure caused changes in the testicular histological structure, which consists apoptosis, and led to changes in several biochemical markers: Malondialdehyde, catalase, superoxide dismutase, and glutathione peroxidase. However, these BPA side effects may be ameliorated in rats treated with BPA-plus-Se. These protective effects of Se may attributable to its ability to remove potentially damaging oxidizing agents in living organisms. The results may confirm that Se countered the oxidant effects and increased the BPA-induced stress response in rats. So, Se promotes the healthy growth and development of mammals by protecting them from oxidative stress. As human are greatly exposed to BPA and it can accumulate in tissues, there is concern about human reproductive functions particularly for occupational workers exposed usually to greater levels of BPA. Thus, the use of BPA in multiple industries must be restricted and the inaccurate usage of plastic containers should be avoided to decrease the health hazards. Administration of Se may protect against the adverse effects of BPA on reproductive functions and structures.


RESUMEN: El bisfenol A (BPA) es un químico industrial ampliamente utilizado para fabricar plásticos de policarbonato para envases y resinas epoxi. Este estudio examinó el efecto de selenio (Se) en la toxicidad del BPA en términos de la estructura histológica, enzimas antioxidantes y los órganos reproductivos (túbulos seminíferos) de ratas albinas. Se dividieron veinticuatro ratas macho adultas en cuatro grupos experimentales: Grupo 1: control; Grupo 2: BPA administrado por vía oral; Grupo 3: BPA administrado por vía oral para; Grupo 4: tratado diariamente con BPA seguido de selenio (Se). El experimento se realizó durante cuatro semanas y se observó que la exposición al BPA provocó cambios en la estructura histológica testicular, incluyendo apoptosis, y alteraciones en varios marcadores bioquímicos:malondialdehído, catalasa, superóxido dismutasa y glutatión peroxidasa. Sin embargo, estos efectos secundarios del BPA pueden mejorar en ratas tratadas con BPA-plus-Se. Estos efectos protectores del Se pueden ser atribuidos a la capacidad de eliminar agentes oxidantes potencialmente dañinos en organismos vivos. Los resultados indicaron que se contrarrestaron los efectos oxidantes y aumentó la respuesta al estrés inducido por BPA en ratas, y favorece el crecimiento y desarrollo en los mamíferos al protegerlos del estrés oxidativo. Debido a la exposición al BPA en el ser humano, se puede acumular en los tejidos, por lo que existe una preocupación por el daño a las funciones reproductivas en particular de los trabajadores que generalmente están expuestos a niveles más altos de BPA. Por lo tanto, se debe restringir el uso de BPA en las industrias y evitar el uso incorrecto de envases de plástico para así disminuir los riesgos para la salud. La administración correcta de Se puede proteger contra los efectos adversos del BPA en las funciones y estructuras reproductivas.

ABSTRACT

SUMMARY: The aim of this study is to investigate the effects of Protocatechuic acid and Corchorus olitorius on streptozotocin (STZ) induced diabetic rat testis tissue. Randomly selected Wistar Albino rats were divided into five groups as; Diabetes Mellitus, Diabetes Mellitus treated with Corchorus Olitorus (STZ+CO), Diabetes Mellitus treated with Protacatechuic acid (STZ+PCA), Corchorus olitorius (CO), Protocatechuic acid (PCA) and Control. Diabetic model was generated by intraperitoneal injection of 60 mg/kg Streptozotosin. After 48 hours of the STZ injection, blood samples were collected from tail vein in order to measure blood glycose levels. Over 250 mg/dL accepted as diabetic subjets and fed with 250 mg/kg Corchorus olitorius or 20 mg/kg PCA by oral gavage for three weeks. At the end of the experiment, right testes were removed and fixed in 10 % neutral formaldehyde for paraffine embedding. Sections were stained by HE, Masson trichrome, PAS and TUNEL for microscopic evaluation. Control, PCA-only and Corchorus olitorius-only treated group testes tissues showed a normal tissue organization, when degeneration in seminiferous tubules, the vacuolization, seperations in spermatogenic cell series, outpouring of cell groups in the lumen, vesicular body formation, liquid accumulation in the interstitial region and edema were observed in STZ induced diabetic models and untreated groups. Besides, higher amount of TUNEL (+) stained cells were determined in STZ group. On the other hand, blood glucose level and number of TUNEL (+) stained cells were decreased as a result of PCA and Corchorus olitorius treatment. Because of the reduction of blood glucose level and apoptotic cell numbers, PCA and Corchorus olitorius decreace the complications of diabetes mellitus induced rat testis.


RESUMEN: El objetivo de este estudio fue investigar los efectos del ácido protocatéquico y Corchorus olitorius sobre el tejido testicular de rata diabética inducida por estreptozotocina (STZ). Las ratas Wistar Albino fueron seleccionadas al azar y se dividieron en cinco grupos; Diabetes Mellitus, Diabetes Mellitus tratada con Corchorus olitorius (STZ + CO), Diabetes Mellitus tratada con ácido protocatéquico (STZ + PCA), Corchorus olitorius (CO), ácido protocatéquico (PCA) y Control. El modelo diabético se generó por inyección intraperitoneal de 60 mg/kg de estreptozotosina. Después de 48 horas de la inyección de STZ, se recogieron muestras de sangre de la vena de la cola para medir los niveles de glucosa. Niveles mayores a 250 mg/dL fueron considerados como especímenes diabéticos y alimentados con Corchorus olitorius de 250 mg/kg o PCA de 20 mg/kg por sonda oral durante tres semanas. Al final del experimento, se extirparon los testículos derechos y se fijaron en formaldehído neutro al 10 % para la inclusión en parafina. Las secciones se tiñeron con HE, tricromo de Masson, PAS y TUNEL para evaluación microscópica. Los tejidos de los testículos de los grupos control, tratados solo con PCA y con Corchorus olitorius mostraron una organización tisular normal. En cambio en modelos diabéticos inducidos por STZ y grupos no tratados se observó degeneración en los túbulos seminíferos, vacuolización, separaciones en series de células espermatogénicas, efusión de grupos celulares en la luz, formación del cuerpo vesicular, acumulación de líquido en la región intersticial y edema. Además, se determinó una mayor cantidad de células teñidas con TUNEL (+) en el grupo STZ. Por otro lado, el nivel de glucosa en sangre y el número de células teñidas con TUNEL (+) disminuyeron como resultado del tratamiento con PCA y Corchorus olitorius. Debido a la reducción del nivel de glucosa en sangre y el número de células apoptóticas, se observó que PCA y Corchorus olitorius disminuyen las complicaciones de los testículos de rata inducidos por diabetes mellitus.

ABSTRACT

SUMMARY: Establishing guidelines for responsible management in fish production systems requires knowledge of the basic biology of the fish to be raised. The objective of this work was to determine the reproductive capacity of hybrids produced from the crossing of females of Pseudoplatystoma metaense with males of Leiarius marmoratus. Males presented a digitiform, unrestricted spermatogonial testicle containing caudal digits producing glycoproteins that do not form a seminal vesicle. It was possible to find free sperm in the lumen of the tubules and in the ducts. The ovary of the females was found to be saccular and synchronous with at least three groups of oocytes. In the first year of life, only oogonia up to previtellogenic oocytes (cortical alveolus 284.9 ± 35.7 mm in diameter) were found. After the second year vitellogenic oocytes 730 ± 3.78 mm in diameter were observed. The events of gonadal development of the hybrids indicate that they are gonochoric, synchronic animals. The maturation peaks in the high-water season, overlapping with the parental species. Therefore, the escape of hybrids from fish cultures to the rivers may increase the risk of crosses, gene introgression, or diminution of the reproductive capacity of the pure species.


RESUMEN: El establecimiento de pautas para la gestión responsable en los sistemas de producción de peces requiere el conocimiento de la biología básica de los peces a criar. El objetivo de este trabajo fue determinar la capacidad reproductiva de los híbridos producidos por el cruce de hembras de Pseudoplatystoma metaense con machos de Leiarius marmoratus. Los machos presentaron un testículo espermatogonial digital no restringido que contiene dígitos caudales que producen glucoproteínas que no forman una vesícula seminal. Fue posible encontrar esperma libre en la luz de los túbulos y en los conductos. Se encontró que el ovario de las hembras era sacular y sincrónico con al menos tres grupos de ovocitos. En el primer año de vida, solo se encontraron oogonia hasta ovocitos previtelogénicos (alvéolo cortical de 284,9 ± 35,7 mm de diámetro). Después del segundo año, se observaron ovocitos vitelogénicos de 730 ± 3,78 mm de diámetro. Los eventos de desarrollo gonadal de los híbridos indican que son animales sincrónicos gonocóricos. La maduración alcanza su punto máximo en la temporada de aguas altas, superponiéndose con las especies parentales. Por lo tanto, el escape de híbridos de cultivos de peces a los ríos puede aumentar el riesgo de cruces, introgresión genética o disminución de la capacidad reproductiva de las especies puras.

ABSTRACT

SUMMARY: The objective of this present investigation was undertaken to study the testicular and epididymal biometrical characteristics in Algerian donkeys throughout the year according to age, body weight and seasonal changes. The study was conducted from February 2019 to January 2020. A total of 24 sexually mature donkeys (Equus asinus) were selected randomly. The testis and epididymis were collected after slaughter of donkeys and separated from the conjunctive and adherent tissues. The epididymis has been carefully removed at the testicular junction. In total, 10 biometric measures were selected and performed. Our results revealed that there are significant differences (P<0.05) between groups in most biometrics values. All biometric parameters varied throughout the year and were affected by the season. Significant differences of the GSI and SC values (P<0.05) were observed in different age groups and seasons. On the other hand, no significant differences were observed between the body weight categories of donkeys. The analysis of the correlation coefficients between the biometric values shows high positive correlations, ranged between 0.98 and 0.72 (P<0.001). There was a high positive correlation between age and all the parameters, ranged from 0.85 to 0.61 (P<0.001). However, there were low negative correlations between season and; testicular and epididymal biometrics. It is the first investigation that describes the male reproductive organs in donkeys of the Algerian race (Equus asinus), on the basis of biometric testicular and epididymal measurements. Our results showed that the essential differences were noted between some biometric parameters and the age, season and body weight of donkeys. In addition, the correlation coefficients were supported between biometric measurements and these factors. However, other approaches are necessary to undertake, such as histology of reproductive organs and hormone measurement, for a deeper understanding of the physiology of reproduction in donkeys.


RESUMEN: El objetivo de esta investigación fue estudiar las características biométricas testiculares y epididimarias en burros Argelinos durante todo el año de acuerdo con la edad, el peso corporal y los cambios estacionales. El estudio se realizó entre febrero de 2019 y enero de 2020. Se seleccionó al azar un total de 24 burros sexualmente maduros (Equus asinus). Los testículos y el epidídimo se recogieron después del sacrificio de los burros y se separaron de los tejidos conjuntivos y adherentes. El epidídimo se eliminó cuidadosamente en la unión testicular. En total, se seleccionaron y realizaron 10 medidas biométricas. Nuestros resultados revelaron que existen diferencias significativas (P <0,05) entre los grupos en la mayoría de los valores biométricos. Todos los parámetros biométricos variaron a lo largo del año y se vieron afectados por la temporada. Se observaron diferencias significativas de los valores de GSI y SC (P <0,05) en diferentes grupos de edad y estaciones. Por otra parte, no se observaron diferencias significativas entre las categorías de peso corporal de los burros. El análisis de los coeficientes de correlación entre los valores biométricos muestra altas correlaciones positivas, entre 0,98 y 0,72 (P <0,001). Hubo una alta correlación positiva entre la edad y todos los parámetros, que varió de 0,85 a 0,61 (P <0,001). Sin embargo, hubo bajas correlaciones negativas entre temporada y biometría testicular y epididimaria. Es la primera investigación que describe los órganos reproductores machos en burros de la raza Argelina (Equus asinus), sobre la base de mediciones biométricas testiculares y epididimarias. Nuestros resultados mostraron que se observaron las diferencias esenciales entre algunos parámetros biométricos y la edad, la estación y el peso corporal de los burros. Además, los coeficientes de correlación fueron compatibles entre las mediciones biométricas y estos factores. Sin embargo, son necesarios otros enfoques, como la histología de los órganos reproductivos y la medición de hormonas, para una mayor comprensión de la fisiología de la reproducción en burros.

ABSTRACT

SUMMARY: This study aimed to investigate the changes in testis tissue of thioacetamide-induced rats and the effect of melatonin on these changes. Thirty-five male Wistar Albino rats were divided into five groups. Group I; Control (n=7), Group II; Melatonin (Mel) (10 mg/kg) a single dose (i.p)(n=7), Group III; Thioacetamide (TAA) (300 mg/kg) (i.p) 2 times with 24 hour intervals (n=7), Group IV; TAA (300 mg/kg) was administered at 24-hour intervals, afterwards of 10 mg/kg single dose of Mel (n=7), Group V; Mel was administered 10 mg/kg a single dose 24 hours before the administration of TAA (n=7). Testis was evaluated histologically, immunohistochemically (Heat Shock Proteins (HSP) 70 and 90), blood serum testosterone, total antioxidant status(TAS) and total oxidant status(TOS) in tissue. The tissue sections of Group III decreased seminiferous tubule diameters, and germinal epithelium spills were observed. HSP70 and HSP90 expressions were increased. There wasn't a statistically significant change in testosterone levels among the groups. While TAS levels decreased in Group III compared to control, TOS levels didn't change. HSP70 and HSP90 decreased in groups with Mel-treated. Mel was found to have both protective and therapeutic effects. According to our results, the therapeutic effect of Mel in thioacetamide-induced acute testicular injury is greater than its protective effect.


RESUMEN: Este estudio tuvo como objetivo investigar los cambios en el tejido testicular de ratas inducidas por tioacetamida y el efecto de la melatonina en estos cambios. Treinta y cinco ratas macho Wistar Albino se dividieron en cinco grupos. Grupo I; Control (n = 7), Grupo II; Melatonina (Mel) (10 mg / kg) una dosis única (i.p) (n = 7), Grupo III; Tioacetamida (TAA) (300 mg / kg) (i.p) 2 veces con intervalos de 24 horas (n = 7), Grupo IV; TAA (300 mg / kg) se administró a intervalos de 24 horas, luego de una dosis única de 10 mg / kg de Mel (n = 7), Grupo V; Mel recibió 10 mg / kg de una dosis única 24 horas antes de la administración de TAA (n = 7). Los testículos se evaluaron histológicamente, inmunohistoquímicamente (proteínas de choque térmico (PCT) 70 y 90), testosterona en suero sanguíneo, estado antioxidante total (EAT) y estado oxidante total (EOT) en el tejido. En secciones de tejido del Grupo III se observó disminución de los diámetros de los túbulos seminíferos y derrames en el epitelio germinal. Se aumentaron las expresiones HSP70 y HSP90. No hubo un cambio estadísticamente significativo en los niveles de testosterona entre los grupos. Mientras que los niveles de EAT disminuyeron en el Grupo III en comparación con el control, los niveles de EOT no cambiaron. HSP70 y HSP90 disminuyeron en los grupos tratados con Mel. Se descubrió que Mel tenía efectos protectores y terapéuticos. Según nuestros resultados, el efecto terapéutico de Mel en la lesión testicular aguda inducida por tioacetamida es mayor que su efecto protector.

ABSTRACT

ABSTRACT Purpose: To evaluate whether components of Testicular Dysgenesis Syndrome (TDS) affect testicular germ cell tumor (TGCT) prognosis and oncological outcomes. According to the hypothesis called TDS; undescended testis, hypospadias, testicular cancer and spermatogenic disorders share the same risk factors and have a combined fetal origin. Materials and Methods: We retrospectively evaluated the stages and oncological outcomes of 69 patients who underwent radical orchiectomy between January 2010 and December 2014 due to TGCT in our department. The presence of undescended testis, hypospadias and semen parameters disorders were recorded according to anamnesis of patients. Results: Among 69 patients with TGCT, only 16 (23.1%) had TDS. Significantly higher rate of TDS (36.1% vs. 9.1%) was observed at the advanced stages of TGCT(p=0.008). In the TDS group, the rates of local recurrence (50% vs. 11.3%, p<0.001), distant metastasis (93.6% vs. 3.8%, p<0.001) and cancer-spesific mortality (87.5% vs. 3.8%, p<0.001) were found significantly higher than those without TDS. The predicted time for recurrence-free survival (13.70±5.13 vs. 100.96±2.83 months, p<0.001) metastasis-free survival (13.12±4.21 vs. 102.79±2.21 months, p <0.001) and cancer-specific survival (13.68±5.38 vs. 102.80±2.19 months, p<0.001) were also statistically lower in this group. Conclusions: According to our preliminary results, there is an apparent relationship between TDS and tumor prognosis. Even if the components of TDS alone did not contain poor prognostic features for TGCT, the presence of TDS was found as the most important independent predictive factor for oncological outcomes in both seminomas and nonseminomas as well as all patients with TGCT.

ABSTRACT

Abstract Introduction: polyorchidism is an unusual pathology, about 200 cases in the world literature. Case report: we reported a case of polyorchidism in a 16-year-old male patient diagnosed by ultrasound and confirmed by magnetic resonance imaging. Discussion: most of the cases presented, there is a supernumerary testis, but there are reports on more than three, up to five testicles with supranumerical gonads on both sides of the scrotum. The diagnosis is usually performed in late puberty, incidentally, with a painless scrotal mass or at the emergency room, presenting a testicular torsion of the whole hemiscrotum or supernumerary testisalone, and the differential diagnosis should be made with epididymal cyst and spermatocele, besides other extra-testicular masses (hydroceles, varicoceles, lipomas, tumors.) and para-testicular masses (hernias, scrotal calculi). After the initial clinical evaluation, ultrasound is the first line subsidiary exam. Magnetic Resonance Imaging is very helpful, just in case the ultrasound diagnosis is uncertain. The supernumerary testishave the same Magnetic Resonance Imaging characteristics as the normal testes (intermediate signal intensity on T1- weighted images and high signal intensity on T2-weighted images).


Resumo Introdução: o poliorquidismo é uma patologia incomum, contando cerca de 200 casos na literatura mundial. Relato de caso: relatamos um caso de poliorquidismo em um paciente do sexo masculino de 16 anos, diagnosticado por ultrassom e confirmado por ressonância magnética. Discussão: na maioria dos casos apresentados, há um testículo supranumérico, mas há relatos de mais de três, até cinco testículos, com gônadas supranuméricas em ambos os lados do escroto. O diagnóstico geralmente é feito no final da puberdade, aliás, com massa escrotal indolor ou no pronto-socorro, apresentando torção de todo o hemiscroto ou somente do testículo supranumerário, e o diagnóstico diferencial deve ser feito com cisto epididimário e espermatocele, além de outros massas extratesticulares (hidroceles, varicoceles, lipomas, tumores) e massas paratesticulares (hérnias, cálculos escrotais). Após a avaliação clínica inicial, o ultrassom é a primeira linha do exame subsidiário. A ressonância magnética é muito útil se o diagnóstico por ultrassom não for certo. Os testículos supranumerários têm as mesmas características de ressonância magnética que os testículos normais (intensidade do sinal intermediário nas imagens ponderadas em T1 e alta intensidade do sinal nas imagens ponderadas em T2).

ABSTRACT

Introducción: El autoexamen de mama y el autoexamen de testículos son métodos de detección temprana sencillos, económicos, seguros, no invasivos, que no requieren ningún instrumento especial para su ejecución y que permiten una mayor conciencia y conocimiento del propio cuerpo. Objetivo: Determinar el conocimiento de la práctica del autoexamen de mama o testículo en un grupo de estudiantes universitarios. Métodos: Estudio descriptivo, transversal. Se aplicó un cuestionario sobre conocimientos de autoexamen de mama o testículo, consumo de tabaco, alcohol y variables sociodemográficas. El análisis de datos incluyó distribución de frecuencias, porcentajes y razones de prevalencia. Resultados: Del total de la muestra, el 43,9 por ciento eran hombres, de ellos el 30,7 por ciento manifestó conocer cómo se debía realizar el autoexamen de testículo. Los masculinos pertenecientes a estratos altos, los que se encontraban cursando tercer año y quienes tenían estudios afines con la facultad de salud mostraron las mayores tasas de conocimiento. De las mujeres, el 73,7 por ciento conocía cómo realizar el autoexamen de mama, demostrando tasas mayores de conocimientos las que cursaban cuarto año, las que pertenecían a estratos altos y las que tenían estudios afines con la facultad de salud. No se encontró asociación estadística con el conocimiento del autoexamen de testículo; mientras que ser mayor de 22 años y pertenecer a estratos altos fueron factores predisponentes para el autoexamen de mama. Conclusiones: Las mujeres tienen mayor percepción de la importancia del autocuidado para su salud, a la vez que manifiestan mayor conocimiento de los procedimientos para realizar el autoexamen. No obstante, existen hombres y mujeres que no saben aún como realizarlo, de ahí la importancia de desarrollar e implementar programas de educación, prevención y promoción del autoexamen en los estudiantes universitarios(AU)


Introduction: Breasts self-examination and testicles self-examination are simple, economic, safe, non-invasive early detection's methods that do not require any special tool for their performance and that foster a higher awareness and knowledge on your own body. Objective: To determine the knowledge of the breast or testicles self-examination practice in a group of university students. Methods: Descriptive, cross-sectional study. It was performed a questionnaire on the knowledge of the breast or testicles self-examination, tobacco and alcohol consumption, and socio-demographic variables. Data analysis included frequencies and percentages distribution, and prevalence ratios. Results: From the total of the sample, 43,9 percent were men, and 30,7 percent of them expressed to have knowledge on how to perform the testicles self-examination. Males corresponding to high strata, the ones that were in third year of the major, and those who had studies related to the Health's Faculty showed higher rates of knowledge. From women, 73,7 percent knew how to perform the breasts self-examination showing higher rates of knowledge the ones that were in the fourth year of the major, the ones that belonged to higher strata and the ones that had studies related with the Health's Faculty. There was not found statistic association with the knowledge on testicles self-examination; while being older than 22 years old and belonging to high strata were predisposing factors for breasts self-examination. Conclusions: Women have higher perception of the importance for health of self-care, while they show more knowledge on the procedures to perform self-examination. Nevertheless, there are men and women that do not know yet how to perform it, that is why it is important to develop and implement programs of education, prevention and promotion of the self-examination in university students(AU)
