Protective effect of loboob (a Persian traditional remedy) on sexual hormones, antioxidant activities and stereological changes of testis tissue on busulfan induced oligospermia in rats

Loboob as a traditional drug in Iranis known for its beneficial effects on busulfan-induced oligospermia. In this experimental study, protective effects of loboob (a Persian traditional remedy) on sexual hormones, antioxidant levels and stereological changes of testis tissue were evaluated in an oligospermia rat model induced by busulfan. Fifty male rats were randomly divided into five different groups: control, received no treatments; and the other groups administrated with a single dose of busulfan (10 mg/kg body weight). After 30 days, these groups were treated with 0, 35, 70 or 140 mg/kg/day of loboob for 60 days. Blood samples were collected for hormone and antioxidant enzyme assays. Unbiased stereology was performed on testis tissues to evaluate the volume of different parts of the testis and the number of various testis cells. Data indicated that FSH, LH and MDA were increased, and testosterone, catalase, SOD were decreased in the busulfan group, while treatment with loboob at 70 and 140 mg/kg significantly improved these parameters (P <0.05). Treatment with 70 and 140 mg/kg of loboob ameliorated the germinal epithelium volume, types A and B spermatogonia, spermatocytes, elongated and round spermatids, and Sertoli cells in the seminiferous tubules (P <0.05). High concentration of loboob also improved testis weight and volume, and leydig cell number (P <0.05). Thus, loboob is more effective for the recovery of seminiferous tubules and their cells than for the interstitial tissue. Loboob with various antioxidants, minerals and vitamins could overcome the side effects of busulfan.

Effect of herbicide based formulations on structure and function of testis in rats

For instant weed management, widely used herbicide formulations (HFs) are Paraquat based formulation (PBF) or Glyphosate based formulation (GBF). Here, we investigated the effect of PBF Gramoxone® and GBF Roundup® on the structure and function of the testis of the male Wistar rats at the pubertal or post pubertal stage. Male rats were gavaged with Gramoxone® (5 mg/kg body wt.) or Roundup® (250 mg/kg body wt.). The treatment period of 25 days starts on a postnatal day (PND) 28 to 53 (from pre-pubertal to the pubertal stage) or 60 days from PND 28 to 88 (from prepubertal to the post pubertal stage). Age-matched control animals received distilled water. The structure of the testes was evaluated by observing changes in its histology and the function of the testes was assessed by estimating serum follicle-stimulating hormone (FSH), luteinizing hormone (LH) and testosterone levels. No significant effect was observed in the structure and function of the testes of the pubertal stage rats on exposure to both herbicide formulations. However, shrunken and distorted seminiferous tubules with oligozoospermia in testes, a non-significant decrease in FSH and LH, and a significant reduction in testosterone levels were noted in the post pubertal stage rats. The results indicated that changes in the testes of post pubertal groups are due to a longer duration of exposure to the Gramoxone® or Roundup® than in pubertal groups, and also the effect of these two formulations was more on the testis structure and function than on the pituitary-testis axis

Gene Expression Endpoints Following Subchronic Thiamethoxam Exposure in Adult Male Rabbits

Aim: to investigate the sub chronic toxicity of thiamethoxam on some parameters of reproductive performance in adult male rabbits including gene expression of LDH-C4, FSH? and LH? and GnRHR. Method: sixteen adult male Chinchilla rabbits were divided into two equal groups. Animals in the first group were treated orally with TMX at dose of 250 mg/kg body weight for 90 days. The second group was served as control. Result: Obtained results showed that TMX increased the relative weight of some reproductive organs including testis and prostate. Hormonal analysis revealed that, TMX induced a significant elevation in the serum testosterone level, while the concentrations of FSH and LH hormones did not exhibit any alterations between treated and control groups. In addition, LDH-C4, FSH? and LH? and GnRHR genes were down regulated in TMX treated group. Conclusion: Administration of thiamethoxam for 90 days in male rabbits induced a noticeable adverse effect on serum testosterone level and down regulated genes related to male rabbit reproductive performance

The Impact of Zinc Oxide Nanoparticle on LH, FSH, and Testosterone Hormones in Mature Male NMRI Rats

Nanoparticles are widely applied in all aspects of modern life because of their unique features such as small size and high surface area.Several types of research have been carried out to discover the feasible detrimental impacts of Nano-particles on human reproduction. The purpose of this study was to examine the impact of zinc oxide nanoparticles in mature male rats through examining LH, FSH, and testosterone sex hormones. Therefore, 30 Naked Mole-RatInitiative (NMRI) rats were divided into 5 groups. Different doses of zinc oxide nanoparticles (250, 500 and 700 mg.kg-1) were intraperitoneally injected to animals only once. Then, the serum level of luteinizing hormone(LH), Follicle StimulatingHormone (FSH), and testosterone hormones were measured using Enzyme-Linked Immunosorbent Assay (ELISA) method after 21 days. The results were analyzed by ANOVA and Tukey tests. The results indicated that zinc oxide nanoparticles doses caused a significant increase in FSH and testosterone level of blood (Respectively) in 250 and 700mg.kg-1in comparison with the control group. Moreover, this research illustrated that zinc oxide nanoparticle can cause a dose-related increase in Testosterone and FSH hormones levels while causing no significant change in LH hormone level

Prediction of efficacy of gonadotropin releasing hormone agonist trigger for final oocyte maturation through post-trigger 12-hour luteinizing hormone, follicle stimulating hormone and progesterone levels in COS: a prospective study

Background: Circulating levels of luteinizing hormone (LH), follicle stimulating hormone (FSH) and progesterone (P4) in serum after administration of gonadotropin releasing hormone agonist (GnRHa) trigger for final oocyte maturation are found to be predictive of oocyte maturity. This prospective study was conducted at a tertiary care centre to evaluate relationship between serum LH, FSH and P4 levels at 12-h post-trigger and oocyte maturity rate and to predict which hormone has maximum sensitivity and specificity for appropriate oocyte maturation.Methods: Women at risk of ovarian hyper-stimulation syndrome who underwent either autologous or donor IVF cycle treated with flexible GnRH antagonist protocol were taken as participants of the study. GnRHa as trigger for final oocyte maturation was given. After 12 hours of agonist trigger, blood sample was drawn to assess LH, FSH and P4 levels in serum. Continuous variables were expressed as mean±SD. Independent sample t test was used for continuous variables which were normally distributed and Mann-Whitney U test for data not normally distributed. Main outcome measures were number of oocytes retrieved, oocyte maturity rate, fertilization rate, cleavage rate and grade of embryos.Results: There was a statistically significant reduction in number of retrieved oocytes, maturity rate, fertilization rate and grade 1 embryos with a concentration of serum LH and P4 less than the cut off value (p < 0.05).Conclusions: Serum LH and P4 level less than the cut off value at 12-hour post-trigger with GnRHa is associated with a dramatically less oocyte maturity rate and fertilization rate.

Study of incidence of premature ovarian failure in patient attending outpatient department for infertility in a tertiary care centre

Background: To assess the incidence of premature ovarian failure in cases attending infertility outpatient Department of Obstetrics and Gynecology in a tertiary care centre. A total of 350 patients attending infertility opd were screened over period of 150 days from which authors observed premature menopause in 10 cases accounting for an incidence of 2.8%. POF affects approximately one in 10,000 women by age 20; one in 1,000 women by age 30; one in 100 women by age 40.  Premature ovarian failure is a common cause of infertility in women.Methods: Patient attending outpatient Department of Obstetrics and Gynecology with age less than 40 years and infertility, symptoms of menopause were enrolled for the study for duration of 150 days.Results: Present study authors found a total of 2.8% of patient presenting in our outpatient department for infertility had Premature ovarian failure.80% of them were symptomatic suffering with symptoms of hormonal deficiencies .100% of patient with infertility diagnosed as premature ovarian failure had low AMH and High FSH and LH levels indicating poor prognosis.Conclusions: Patient presenting with infertility and amenorrhoea can be cases of premature menopause. Here it is essential to investigate and treat the patient. Infertility might be one of the early presenting symptoms if not the first one. These patients if treated and diagnosed early can have a better living. Considering the wide spectrum of functional derangements in patient with early menopause and benefits of early hormone replacements these patients should be diagnosed and treated early.

Association of Thyroid Hormones with Prolactin, Follicle Stimulating Hormone and Luteinizing Hormone in Female Infertility

Human infertility is a major health problem worldwide having its impact on the social, psychological, economical and sexual life of a couple. Methods: Total of 80 subjects (Out of which 50 infertile female and 30 normal fertile female) were selected on gynecology infertility outpatient department between age group of 20 to 44 years. Out of 50 infertile women, 34 were of primary infertility and 16 of secondary infertility. Results: Statistically significant higher serum TSH levels were noted in the infertile subject with euthyroid (p=0.03) and hypothyroidism (p<0.001) when their distributions were compared to their respective fertile subjects. The rise in serum FT3 and FT4 in the infertile subjects with hyperthyroidism was found to be not significant as compared to the fertile subjects with hyperthyroidism. The mean serum prolactin concentration in the infertile female with euthyroid was significantly higher (p<0.01) than the fertile subjects with euthyroid. The infertile women with hypothyroidism had statistically significant higher prolactin levels than the other three categories (the fertile female and the infertile subjects with euthyroid and hyperthyroidism) (p<0.01). Conclusion: High prevalence of hypothyroidism was seen in infertile female. These disorders may lead to menstrual irregularities resulting in infertility.

CONCLUSION:-This study was suggested that, TVS is the most the important diagnostic tool and serum LH/FSH ratio was secondary tool.

Improvement of fertility parameters with tribulus terrestris and anacyclus pyrethrum treatment in male rats

ABSTRACT Objective Anacyclus Pyrethrum (AP) and Tribulus Terrestris (TT) have been reported as male infertility treatment in several studies; however, in Iranian traditional medicine these two plants are prescribed simultaneously. In this study, we aimed to determine the effects of AP and TT extracts both separately and simultaneously on the male Wistar rat fertility parameters. Materials and Methods 32 male Wistar rats were divided into 4 groups: Control, TT, AP, and AT treated groups. Treatment continued for 25 days and rats were weighed daily. Their testes were dissected for histological studies. Sperm analysis including sperm count, viability and motility were performed. Serum was obtained to evaluate testosterone, LH and FSH levels. Histological studies were conducted to study Leydig, and Sertoli cells, spermatogonia and spermatid cell numbers, and to measure seminiferous diameter and epithelium thickness. Results Sperm count increased in all the treatment groups. Sperm viability and motility in AT and AP groups were elevated. TT and AT groups showed significantly increased testosterone level compared to control group (P=004, P=0.000, respectively) and TT, AP and AT treatment groups showed increased LH level (P=0.002, P=0.03 and P=0.000, respectively) compared to control, while only AT group showed increased FSH (p=0.006) compared to control. Histological studies showed significant increase of spermatogonia, Leydig and Sertoli cell numbers and epithelial thickness in AT group compared to other groups. All the treatment groups had higher number of Leydig, spermatogonia and spermatid cells. Conclusion TT and AP improved sexual parameters; however, their simultaneous administration had higher improving effects on studied parameters.

Endocrine Dysfunction in Recurrent Pregnancy Loss

Introduction: Miscarriage is the spontaneous loss of theconceptus before 20 weeks of gestation. Several disordersare known to contribute to recurrent miscarriage including:chromosomal anomalies; anti-cardiolipin antibodies;endocrine disorders such as poorly controlled diabetesmellitus; hyperprolactinaemia and thyroid diseases; andpelvic anatomic abnormalities. Study aimed to investigate theendocrine dysfunction in recurrent pregnancy lossMaterial and Methods: A prospective study comprising 70subjects was carried out. Fifty cases of recurrent abortionsconstituted the study group. Twenty healthy multipara femalesof same reproductive age group constituted the controlgroup. Venous blood samples were collected, and serum wasanalyzed for hormone analysis (T3, T4, TSH, LH, FSH, PRL,Testosterone) by ELISA method.Results: The mean prolactin level in cases of recurrentabortions was 19.96 ng/ml, while in controls was 11.77 ng/ml. The p value was 0.006 which was found to be statisticallyhighly significant. The mean TSH level in recurrent abortionscases was 5.81 mIU/L, while in controls was 1.95 mIU/L. Thep value was 0.004 which was found to be statistically highlysignificant.Conclusion: The patients with recurrent abortions hadsignificantly raised levels of TSH and Prolactin. Theprevalence of thyroid disorder and hyperprolactinemiawere higher in pregnant women with a history of recurrentabortion compared with healthy pregnant control population.Universal screening of pregnant females for endocrine profilecan improve the foetal outcome as well as social well-beingof females.

A prospective analysis of polycystic ovarian syndrome in infertile women

Background: Polycystic ovarian syndrome (PCOS) is a frequently occurring metabolic and reproductive endocrinopathy. Young women with PCOS mainly present with reproductive problems such as hyperandrogenism, menstrual irregularities, infertility and chronic anovulation. Despite its high prevalence and implications on reproductive health, PCOS is underdiagnosed. The objective was to study the prevalence of PCO in women with infertility, their symptomatology, endocrine profiles and coexisting factors of infertility in women with PCOS.Methods: A prospective study was performed over a period of 6 months. Women presenting with infertility were subjected to detailed history taking, general and gynecological examination. Women with features of PCOS on ultrasound were identified and advised investigations such as serum FSH, LH, prolactin and laparoscopy when indicated.Results: During the study period, 102 patients consulted the infertility clinic, out of which 56 were diagnosed with PCOS. The prevalence of PCOS was found to be 54.9% among infertile women. Menstrual irregularity was found in 33 (59%) women, however, 23 (41%) had regular menstrual cycles. 4 among the 33 patients complained of dysmenorrhea, 5 had heavy menstrual bleeding. On examination, 19 (33.9%) were found hirsute, 8 (14.28%) had thyroid enlargement and 2 (3.57%) had galactorrhea. Investigations revealed mean FSH and LH levels of 8.7±2SD and 13.7±2SD respectively and mean LH/FSH ratio of 1.57±2SD.Conclusions: PCOS is a heterogenous disorder and with its high prevalence in infertile women, proper diagnosis and management is essential as it has many potential metabolic and cardiovascular risks if not managed appropriately.

Recent progress of NR5A1 gene mutation / 国际儿科学杂志

NR5A1 gene mutation is one of the common cause of 46 XY dysplasia (46,XY disorder of sex development,46,XY DSD),which is an autosomal dominant disease.It has wide phenotypes:46,XY gonadal dysplasia is the most common one,site-specific mutations can lead to adrenal dysfunction and may affect the height.In recent years,more and more studies have shown that the mutation of NR5A1 gene can lead to 46,XX ovotesticular DSD and 46,XX testicular DSD.The disease is also characterized by hypergonadotropic hypogonadism,so LH and FSH are high,especially the FSH,leading to a decrease in LH/FSH.The treatment of NR5A1 gene mutation is mainly symptomatic.Gender identification needs to take many factors into consideration.Before puberty,children can use GnRHa to inhibit gonad development and avoid premature ovarian failure.In this review,recent progress of NR5A1 is summarized.

Síndrome de Ovarios Poliquísticos / Polycystic ovary syndrome

Resumen El síndrome de ovarios poliquísticos (SOPQ) es la disfunción endocrino- metabólica más frecuente en mujeres de edad reproductiva. El diagnostico de esta patología se basa en la presencia de anovulación, hiperandrogenismo y ovarios poliquísticos. La etiología del SOPQ es compleja y multifactorial; por lo cual el tratamiento se basa en tratar las manifestaciones clínicas y la inducción de la ovulación en el momento que se desee la concepción.

Abstract Polycystic ovary syndrome is the most common endocrinologic and metabolic disfunction in reproductive- aged women. The diagnosis of this pathology is based on the presence of ovulatory dysfunction, hyperandrogenism and polycystic ovaries. Its ethiology is complex and with multiple factors, therefore its treatment is based on fixing the clinical manifestations of the syndrome and in the case of women who would like to conceive, in inducing ovulation.

Demographic And Hormonal Profile Of Acne In Adolescence And Post Adolescence.

Background: Acne vulgaris is one of the most common skin diseases affecting majority of the teens and reaching its pinnacle during adulthood. In some severe cases, it leads to pronounced skin deformity which adversely dampen the self-esteem of the affected which can eventually lead to depression and even suicides. Usually this disease invariably diminishes in twenties but in some cases, it might even persist in thirties, forties and beyond. Majority of females suffer from mild to moderate acne at some stage of life. Androgens cause enlargement and overstimulation of the sebaceous glands in people with acne and this leads to overproduction of sebum coupled with sluggish exfoliation process leads to blocked pores and development of acne, so the present study conducted with objectives to compare hormonal levels of serum testosterone, LH, FSH among patients with and without Acne and to compare the hormonal levels in different categories of acne among study participants.

Gonadotrophic, prolactin, corticosterone, and gonadal hormones levels over 15 months in Giant Amazon River Turtles - Podocnemis expansa (Schweigger, 1812) (Testudines: Podocnemididae), in captive conditions / Gonadotrofinas, prolactina, corticosterona, e as hormonas sexuais durante 15 meses de Tartarugas da Amazônia - Podocnemis expansa (Schweigger, 1812) (Testudines: Podocnemididae), em condições de cativeiro

Abstract In order to achieve successful captive breeding the Podocnemis expansa, it is necessary to study their reproductive endocrinology. The purpose of this research was to evaluate and characterize plasma concentrations in gonadotrophic, gonadic, corticosterone and prolactin hormones from Giant Amazon Turtles under captive conditions. Blood samples were collected over a 15 month period. The samples were assayed by the use of radioimmunoassay, prolactin, corticosterone, LH, FSH, testosterone, 17β-estradiol and progesterone. We verified significant seasonal pattern increase in 17β-estradiol levels and decrease in progesterone levels in the course of a year, which indicates vitellogenesis. This is related to normal ovarian cycles and possibly to the functional integrity of the hypothalamus-pituitary-gonad axis of captive females. There were negative correlations between testosterone and corticosterone in the male samples, suggestive of stress (management stress) on the reproductive system. The plasma concentrations of gonadotrophic, gonadic, prolactin and corticosterone hormones may be used as a reference for further research and possible therapeutic approaches. The data collected during this research are unprecedented for this species and may serve as a reference for future research regarding the reproductive cycle of this turtle, also allowing reproductive management while in captivity. Information about these hormones must be gathered from wild populations during different periods of the year for better clarification of the reproductive physiology of this species.

Resumo Com o objetivo de obter reprodução em cativeiro de Podocnemis expansa, é necessário reunir o conhecimento a respeito de sua endocrinologia reprodutiva. O objetivo deste trabalho foi avaliar e caracterizar as concentrações plasmáticas de hormônios gonadotróficos, gonadais, corticosterona e prolactina em Tartarugas da Amazônia em condições de cativeiro. Amostras de sangue foram coletadas durante 15 meses. As amostras foram ensaiadas pelo uso de um radioimunoensáio, prolactina, corticosterona, LH, FSH, testosterona, 17β-estradiol e progesterona. Verificou-se aumento de padrão sazonal significativo nos níveis de 17β-estradiol e diminuição dos níveis de progesterona ao longo do ano, o que indica o recrutamento folicular. Isto está relacionado com ciclos ovarianos normais e possivelmente para a integridade funcional do eixo hipotálamo-hipófise-gônadas de fêmeas em cativeiro. Houve correlação negativa entre testosterona e corticosterona nas amostras do sexo masculino, sugestivos de efeito do estresse de manejo sobre o sistema reprodutivo. As concentrações plasmáticas de hormônios gonadotrofinas, gonadais, prolactina e hormônios corticosterona pode ser usado como referência para futuras pesquisas e possíveis abordagens terapêuticas. Os dados médios coletados durante a pesquisa são inéditos para a espécie e pode servir como referência para futuras pesquisas sobre o sistema reprodutivo da tartaruga, também permitindo manejo reprodutivo em cativeiro. Informações sobre esses hormônios devem ser recolhidas a partir de natureza selvagem em diferentes períodos do ano para melhor esclarecimento da fisiologia da reprodução desta espécie.

Utilidad de un esquema combinado de FSH + LH recombinantes versus FSH recombinante sola en ciclos de fertilización in vitro / Recombinant FSH versus recombinant FSH + LH during GnRH antagonist ovarian stimulation for in vitro fertilization

Resumen OBJETIVO: comparar el efecto de añadir LH recombinante a ciclos de estimulación para reproducción asistida versus ciclos solo estimulados con FSH recombinante (FSHr). MATERIALES Y MÉTODOS: estudio retrospectivo, comparativo, observacional y transversal de ciclos de fertilización in vitro efectuados en el Centro Mexicano de Fertilidad del CEPAM divididos en dos grupos, según el tipo de gonadotropina administrada. RESULTADOS: se estudiaron 529 ciclos en los que el desarrollo folicular y la cantidad de ovocitos fueron mayores en el grupo estimulado solo con FSHr. Sin embargo, el porcentaje de ovocitos en metafase II fue mayor en el grupo con LHr. La tasa de embarazo fue mayor en el grupo estimulado con LHr. CONCLUSION: la ventaja de añadir LHr a ciclos de estimulación en reproducción asistida se refleja en mayores tasas de embarazo.

Abstract OBJECTIVE: To evaluate the effect of adding recombinant LH to IVF GnRH cycles compared to recombinant FSH stimulated cycles. MATERIALS AND METHODS: A retrospective, observational, cross-sectional study of 486 cycles of in vitro fertilization was done in the Centro Mexicano de Fertilidad of CEPAM (Hospital Angeles Lomas). We included 529 cases where it was used a stimulation protocol GnRH antagonist flexible scheme and analyzed depending on the utilized gonadotropin scheme. RESULTS: 529 cycles were studied in which the follicular development and the number of oocytes were higher in the group stimulated with FSHr alone. However, the percentage of oocytes in metaphase II was higher in the group with LHr. The pregnancy rate was higher in the group stimulated with LHr. CONCLUSION: There is a benefit of adding rLH to IVF GnRH antagonist stimulation protocols resulting in higher pregnancy rates.
