ABSTRACT

Abstract Objective It has been suggested that excess body weight could represent a risk factor for infertility outcomes. The present study aimed to evaluate the association of overweight and anovulation among infertile women with regular menstrual cycles. Methods We conducted a retrospective case-control study with consistently anovulatory patients undergoing assisted reproduction treatment. The patients were stratified into normal weight (body mass index [BMI]: 18.5-24.9kg/m2) and overweight (BMI: 25.0- 29.9kg/m2).Those with polycystic ovary syndrome or obesity were excluded. The groups were matched for age, duration of infertility, prolactin, follicle stimulating hormone (FSH), thydroid stimulating hormone (TSH), luteinizing hormone (LH), and estradiol levels. Results Overweight was significantly associated with anovulation, when using the World Health Organization (WHO) criteria for anovulation: progesterone levels>5.65 ng/ml and ultrasonography evidence of follicle collapse (odds ratio [OR]: 2.69; 95% confidence interval [CI95%]: 1.04-6.98). Conclusion Body mass index above the normal range jeopardizes ovulation among non-obese infertile women with regular menstrual cycles.


Resumo Objetivo O excesso de peso corporal tem sido associado como fator de risco para infertilidade. Este estudo teve como objetivo avaliar a associação de sobrepeso e anovulação entre mulheres inférteis com ciclos menstruais regulares. Métodos Realizamos um estudo retrospectivo de caso-controle com mulheres com anovulação consistente em tratamento por reprodução assistida. As pacientes foram estratificadas entre aquelas com peso normal (índice de massa corporal [IMC]: 18,5- 24,9 Kg/m2) e as com sobrepeso (IMC: 25,0-29,9 Kg/m2). As pacientes com síndrome do ovário policístico ou obesidade foram excluídas. Os grupos foram pareados por idade, duração da infertilidade, níveis de prolactina, hormônio folículo-estimulante (FSH), hormônio tiroestimulante (TSH), hormônio luteinizante (LH) e estradiol. Resultados O excesso de peso associou-se significativamente à anovulaçãoquando usados os critérios de anovulação da Organização Mundial de Saúde (OMS): níveis de progesterona>5,65 ng/ml e evidência ultrassonográfica de colapso folicular (razão de chances [RC]: 2,69; IC95%: 1,04-6,98). Conclusão O IMC acima da faixa normal compromete a ovulação em mulheres inférteis não obesas com ciclos menstruais regulares.

ABSTRACT

Abstract Objective To investigate whether patients with a previous recombinant follicle stimulating hormone (rFSH)-stimulated cycle would have improved outcomes with rFSH + recombinant luteinizing hormone (rLH) stimulation in the following cycle. Methods For the present retrospective case-control study, 228 cycles performed in 114 patients undergoing intracytoplasmic sperm injection (ICSI) between 2015 and 2018 in an in vitro fertilization (IVF) center were evaluated. Controlled ovarian stimulation (COS) was achieved with rFSH (Gonal-f, Serono, Geneva, Switzerland) in the first ICSI cycle (rFSH group), and with rFSH and rLH (Pergoveris, Merck Serono S.p.A, Bari, Italy) in the second cycle (rFSH + rLH group). The ICSI outcomes were compared among the groups. Results Higher estradiol levels, oocyte yield, day-3 high-quality embryos rate and implantation rate, and a lower miscarriage rate were observed in the rFSH + rLH group compared with the rFSH group. In patients < 35 years old, the implantation rate was higher in the rFSH + rLH group compared with the rFSH group. In patients ≥ 35 years old, higher estradiol levels, oocyte yield, day-3 high-quality embryos rate, and implantation rate were observed in the rFSH + rLH group. In patients with ≤ 4 retrieved oocytes, oocyte yield, mature oocytes rate, normal cleavage speed, implantation rate, and miscarriage rate were improved in the rFSH + rLH group. In patients with ≥ 5 retrieved oocytes, higher estradiol levels, oocyte yield, and implantation rate were observed in the rFSH + rLH group. Conclusion Ovarian stimulation with luteinizing hormone (LH) supplementation results in higher implantation rates, independent of maternal age and response to COS when compared with previous cycles stimulated with rFSH only. Improvements were also observed for ICSI outcomes and miscarriage after stratification by age and retrieved oocytes.


Resumo Objetivo: Investigar se há algum efeito da suplementação com hormônio luteinizante (LH, na sigla em inglês) no regime com antagonista do hormônio liberador de gonadotropina (GnRH, na sigla em inglês) sobre os resultados dos ciclos consecutivos de injeção intracitoplasmática de espermatozoides (ICSI, na sigla em inglês). Métodos Para o presente estudo retrospectivo de caso-controle, foram avaliados 228 ciclos de microinjeção intracitoplasmática de espermatozoides (ICSI, na sigla em inglês) realizados em 114 pacientes entre 2015 e 2018 em um centro privado de fertilização in vitro (FIV) afiliado a uma universidade. O estímulo ovariano controlado (EOC) foi feito com hormônio folículo- estimulante recombinante (rFSH, na sigla em inglês) (Gonal-f, Serono, Genebra, Suíça) no primeiro ciclo de ICSI (grupo rFSH), e com rFSH e rLH (Pergoveris, Merck Serono S.p.A, Bari, Itália) no segundo ciclo (grupo rFSH + rLH). Os desfechos dos ciclos de ICSI foram comparados entre os grupos. Resultados Níveis mais elevados de estradiol, de recuperação oocitária, taxa de embriões de alta qualidade no 3° dia e taxa de implantação, e menor taxa de aborto foram observados no grupo rFSH + rLH. Em pacientes < 35 anos, a taxa de implantação foi maior no grupo rFSH + rLH em comparação com o grupo rFSH. Em pacientes com ≥ 35 anos, maiores níveis de estradiol, recuperação oocitária, a taxa de embriões de alta qualidade no 3° dia e a taxa de implantação foram observados no grupo rFSH + rLH. Em pacientes com baixa resposta ao EOC (≤ 4 oócitos recuperados), a recuperação oocitária, a taxa de oócitos maduros, a taxa de velocidade normal de clivagem, a taxa de implantação e a taxa de aborto foram melhoradas no grupo rFSH + rLH. Em pacientes com resposta normal ao EOC (≥ 5 oócitos recuperados), níveis mais elevados de estradiol, recuperação oocitária e taxa de implantação foram observados no grupo rFSH + rLH. Conclusão A estimulação ovariana com suplementação de LH resultou em taxas de implantação mais altas, independentemente da idade materna e da resposta ao EOC, em comparação com os ciclos anteriores estimulados apenas com rFSH. Melhorias também foram observadas nos resultados da ICSI e na taxa de aborto quando as pacientes foram estratificadas por idade e número de oócitos recuperados.

ABSTRACT

Abstract The process of ovulation involves multiple and iterrelated genetic, biochemical, and morphological events: cessation of the proliferation of granulosa cells, resumption of oocyte meiosis, expansion of cumulus cell-oocyte complexes, digestion of the follicle wall, and extrusion of the metaphase-II oocyte. The present narrative review examines these interrelated steps in detail. The combined or isolated roles of the folliclestimulating hormone (FSH) and luteinizing hormone (LH) are highlighted. Genes indiced by the FSH genes are relevant in the cumulus expansion, and LH-induced genes are critical for the resumption ofmeiosis and digestion of the follicle wall. A nonhuman model for follicle-wall digestion and oocyte release was provided.


Resumo O processo de ovulação envolve modificações genéticas, bioquímicas e morfológicas múltiplas e interrelacionadas: suspensão da proliferação das células da granulosa, reinício da meiose do oócito, expansão das células do complexo cumulus-oócito, digestão da parede folicular, e extrusão do oócito. Esta revisão narrativa examina em detalhes cada um desses eventos e os principais genes e proteínas envolvidos. Mais importante, a ação combinada ou isolada do hormônio folículo-estimulante (HFE) e do hormônio luteinizante (HL) é destacada. Detalha-se o papel do HFE na expansão do cumulus e do HL na digestão da parede folicular, permitindo a extrusão do oócito na superfície ovariana. Proveu-se um modelo não humano para explicar a digestão da parede folicular.

ABSTRACT

Follicle-stimulating hormone (FSH) was once thought to play a role only in reproduction, promoting follicle development and maturation in women and spermgenesis in men. However, in recent ten years, FSH has been found to have new functions on metabolic regulation and aging. FSH regulates bone formation, fat metabolism, energy homeostasis, cholesterol production and cardiovascular disease by binding with its receptor FSHR. These newly discovered regulatory roles of FSH are exciting, as it is suggested that blocking FSH may have potential translational impacts on treatments of a series of age-related diseases, including osteoporosis, obesity, dyslipidemia, cardiovascular disease.

ABSTRACT

Under the guidance of the theory of "kidney governing reproduction", this study demonstrated the mechanism of six types of ovulatory infertility caused by kidney deficiency and blood stasis, including anovulatory bleeding, polycystic ovary syndrome, hyperprolactinemia, luteinized unruptured follicle syndrome, luteal phase deficiency, and primary ovarian insufficiency. A series of studies have confirmed that integrated Chinese and western medicine can increase the responsiveness of the ovaries to gonadotropins and improve ovarian function by regulating the effects of estradiol(E_2), prolactin(PRL), and reducing follicle-stimulating hormone(FSH), luteinizing hormone(LH), progestin(P), and testosterone(T). It can also improve ovulation rate and pregnancy success rate by promoting follicle development, discharging, and synchronizing endometrial growth. This study illustrated the diagnosis and treatment of ovulatory infertility caused by kidney deficiency and blood stasis with integrated traditional Chinese and Western medicine in the "disease-syndrome-symptom" research mode, and highlighted the traditional Chinese medicine(TCM) idea of differentiating diseases based on syndromes and unique advantages of the combination of disease differentiation and syndrome differentiation, and interpreted TCM principle of "treating different diseases with the same method".

ABSTRACT

The methanolic extract of Buchholzia coriacea seeds (MEBC) has been reported to induce male reproductive toxicity by decreasing sperm parameters and fertility index. To elucidate the possible mechanism(s), the effects of graded doses of MEBC on sex hormones and sperm profile were investigated in this study. The MEBC (e.g., 50, 200, 400, and 600 mg/kg) was administered daily (p.o.) to male Wistar rats for 6 weeks, while a concurrent control group received distilled water (vehicle). Then, the animals were sacrificed under sodium pentobarbital anaesthesia. Weights of organs were recorded, and the sperm profile was determined microscopically. Testosterone, luteinizing hormone (LH), and follicle stimulating hormone (FSH) were assayed from the obtained serum using the ELISA technique. Sperm motility was significantly reduced by MEBC (i.e., 50 and 200 mg/kg), and sperm count reduced in all treated groups in a dose-dependent manner compared with that of the control. Serum testosterone, LH, and FSH decreased in treated rats. A histopathological examination of testes showed a considerable depletion and necrosis of the epithelium of seminiferous tubules. The result suggests that Buchholzia coriacea seeds induce male reproductive toxicity by suppressing the pituitary-gonadal axis.

ABSTRACT

ABSTRACT Objectives The determinants of an increased risk of an organic pathology underlying central precocious puberty (CPP) in girls remain contentious. The present study aimed to determine the clinical and hormonal findings that can be used to differentiate organic and idiopathic CPP in girls as a screening method so that only those considered likely to have organic CPP undergo cranial magnetic resonance imaging (MRI). Subjects and methods The medical records of 286 girls that received GnRH agonist (GnRHa) therapy for CPP were retrospectively evaluated. Chronological and bone age, height, pubertal stage, and basal/stimulated gonadotropin and estradiol (E2) levels, as well as cranial MRI findings at the time CPP was diagnosed were recorded. Clinical and hormonal parameters that can be used to differentiate between girls with organic and idiopathic CPP were identified using ROC curves. Results Organic CPP was noted in 6.3% of the participants. Puberty started before age 6 years in 88.9% of the girls with organic CPP. Mean E2 and peak luteinizing hormone (LH) levels were higher in the girls with organic CPP than in those with idiopathic CPP that were matched for pubertal stage, as follows: early stage puberty (Tanner 2 and 3): E2: 62.4 ± 19.8 pg/mL vs. 29.1 ± 9.5 pg/mL; peak LH: 16.8 ± 3.2 IU/L vs. 12.2 ± 3.7 IU/L; advanced stage puberty (Tanner 4): mean E2: 87.6 ± 3.4 pg/mL vs. 64.6 ± 21.2 pg/mL; peak LH: 20.8 ± 0.4 IU/L vs. 16.6 ± 5.8 IU/L (P < 0.001 for all). Thresholds for differentiating organic and idiopathic CPP in girls with early-stage puberty were 38.1 pg/mL for E2 (100% sensitivity and 80.4% specificity) and 13.6 IU/L for peak LH (100% sensitivity and 66.4% specificity). Conclusion Pubertal symptoms and signs generally begin before age 6 years and hormone levels are much higher than expected for pubertal stage in girls with organic CPP. Based on the present findings, cranial MRI is recommended for girls aged < 6 years, as the risk of diagnosing an organic pathology is highest in this age group. Hormone levels higher than expected for pubertal stage might be another indication for cranial MRI, regardless of patient age. Cranial MRI should be performed in girls with early-stage puberty, and an E2 level > 38 pg/mL and/or a peak LH level > 13.6 IU/L.

ABSTRACT

ABSTRACT Objective To determine the optimal cut-off value for follicle stimulating hormone (FSH) to predict the outcome of microsurgical testicular sperm extraction (micro-TESE) in patients with nonobstructive azoospermia (NOA). Subjects and methods We included a total number of 180 patients with NOA. The serum level of FSH was determined and all the subjects underwent micro-TESE. We determined the optimal cut-off value for FSH and assessed whether the test could be effectively used as a successful predictor of sperm retrieval by calculating the Receiver Operating Characteristic (ROC) area under the curve. Results Overall we included a total number of 171 patients with mean age of 34.3 ± 8.6 years. The micro-TESE was considered to be successful in 79 (43.8%) while it failed in 92 (56.2%) patients. We found that the mean level of serum FSH was significantly higher in group those with failed micro-TEST compared to successful group (p < 0.001). The cut-off value for FSH was calculated to be 14.6 mIU/mL to predictive the outcome of micro-TESE with a sensitivity of 83.5% [73.5%-90.9%] and a specificity of 80.3% [69.5%-88.5%]. At this value, the other parameters were calculated to be PPV, 81.5%; NPV, 82.4; LR+, 4.23; and LR-, 0.21. Conclusions The results of the current study indicate that FSH plasma levels above 14.6 mIU/mL can be considered to be the failure predictor of the micro-TESE in NOA patients.

ABSTRACT

Abstract Objective The present study aimed to analyze cardiac autonomic modulation via spectral and symbolic analysis of heart rate variability (HRV) in women with polycystic ovary syndrome (PCOS) who were subjected to two consecutive tilt tests. Methods A total of 64 women were selected and divided into 2 groups: control (without PCOS), and PCOS. Concentrations of follicle-stimulating hormone, luteinizing hormone, prolactin, estradiol, homocysteine, sex hormone-binding globulin, thyroid stimulating hormone, fasting insulin, testosterone, androstenedione, and 17-hydroxyprogesterone levels, triglycerides, free androgen index (FAI), and homeostasis assessment model (HOMA-IR) were assessed. Cardiac autonomic modulation was evaluated by spectral and symbolic analyses during two consecutive tilt tests (two moments) and supine moments before, between and after (three moments) the tilt tests. Results Women with PCOS had higher fasting insulin, HOMA-IR indexes, testosterone and FAI. Additionally, we observed that the PCOS group had greater sympathetic autonomic cardiac modulation in supine 2, tilt 1, and supine 3 moments compared with controls. Conclusion Women with PCOS had higher autonomic sympathetic cardiac modulation even after a second tilt test. No adaptation to this provocative test was observed. Spectral analysis was more sensitive for identifying differences between groups than the symbolic analysis.


Resumo Objetivo O presente estudo teve como objetivo analisar a modulação autonômica cardíaca por análise espectral e simbólica da variabilidade da frequência cardíaca (VFC) em mulheres com síndrome dos ovários policísticos (SOP) que foram submetidas a dois testes consecutivos de inclinação. Métodos Um total de 64 mulheres foram selecionadas e divididas em 2 grupos: controle (sem SOP) e SOP. Concentrações de hormônio folículo-estimulante, hormônio luteinizante, prolactina, estradiol, homocisteína, globulina de ligação a hormônios sexuais, hormônio estimulante da tireóide, insulina em jejum, testosterona e androstenediona e níveis de 17-hidroxiprogesterona, triglicerídeos, índice de andrógeno livre (FAI) e homeostase modelo de avaliação (HOMA-IR) foram avaliados. A modulação autonômica cardíaca foi avaliada por análises espectrais e simbólicas durante dois testes de inclinação consecutivos (dois momentos) e momentos supinos antes, entre e após (três momentos) os testes de inclinação. Resultados Mulheres com SOP apresentaram insulina em jejuM, índices HOMA-IR, testosterona e FAI mais altos. Além disso, observamos que o grupo PCOS apresentou maior modulação cardíaca autonômica simpática nos momentos supino 2, inclinado 1 e supino 3 em comparação aos controles. Conclusão Mulheres com SOP apresentaram modulação cardíaca simpática autonômica mais alta mesmo após um segundo teste de inclinação. Nenhuma adaptação a esse teste provocativo foi observada. A análise espectral foi mais sensível para identificar diferenças entre os grupos do que a análise simbólica.

ABSTRACT

ABSTRACT Objective The aim of this study was to investigate polycystic ovary syndrome (PCOS) and to explore the relationship between body fat percentage and metabolic markers. Subjects and methods Sedentary women were assigned to PCOS (N = 60) and CONTROL (N = 60) groups. Each group was subdivided into three subgroups according to body fat percentage (22-27%, 27-32% and 32-37%). The protocol consisted of assessments of glucose, insulin, androgens, follicle stimulating hormone (FSH), luteinizing hormone (LH), 17-hydroxyprogesterone (17-OHP), leptin, adiponectin, tumor necrosis factor (TNF-α) and interleukin-6 (IL-6). Results The PCOS subgroups showed higher concentrations of androgens, LH and 17-OHP. Leptin showed direct relationship with increased body fat percentage, whereas adiponectin showed the inverse effect. However, both were unaffected by PCOS. TNF-α and IL-6 were higher in PCOS women and showed a direct relationship with increased body fat percentage. Glucose showed direct relationship with body fat percentage, whereas insulin presented higher values in PCOS women and direct relationship with increased body fat percentage. Conclusions Our findings indicate that PCOS and body fat percentage directly influence concentrations of insulin, TNF-α and IL-6, whereas leptin and adiponectin are influenced only by the increase in body fat percentage in these women.

ABSTRACT

OBJECTIVE@#To investigate the efficacy and safety of aromatase inhibitor letrozole in treatment of male children with disorders of sex development (DSD).@*METHODS@#Clinical data of 12 male DSD children with a mean age of 14.6±2.5 years admitted to Peking Union Medical College Hospital from January 2014 to January 2016 were retrospectively analyzed. The patients were treated with letrozole (1.25-2.5 mg, once a day) for 3 months or longer, and followed up for 0.5-2.5 years. Clinical manifestation and laboratory test findings were documented, and the efficacy and safety were evaluated.@*RESULTS@#After half-year treatment, the blood luteinizing hormone (LH), follicle-stimulating hormone (FSH) and testosterone levels of patients increased (all < 0.05), and estrogen levels decreased from baseline ( < 0.05). After 1 year of treatment, the blood testosterone level was significantly higher ( < 0.05); the LH and FSH levels tended to increase and the estrogen level tended to decrease, but there was no significant statistical difference ( >0.05). Semen was routinely detected in 8 patients, and sperms were detected in semen of 3 patients with hypospadias. There were no significant changes in biochemical results after treatment, and no significant adverse event was observed during the treatment.@*CONCLUSIONS@#Letrozole can effectively increase testosterone levels in patients with disorders of sex development and promote spermatogenesis, it has no significant adverse effects in short-term administration.

ABSTRACT

The aim of this paper was to study the effect of Wubi Shanyao Pills on sexual dysfunction in rats with kidney-Yang deficiency and to investigate its possible mechanism. Adenine(100 mg·kg~(-1)) was administered to male SD rats for 8 weeks to establish kidney-Yang deficiency model, and at the same time, Wubi Shanyao Pills(2, 1, 0.5 g·kg~(-1)) were administered to rats for 8 weeks. The syndrome manifestation of kidney-Yang deficiency was observed in rats and the scores of symptoms were evaluated. Sexual behavior indexes(incubation period and times of capture, straddle and ejaculation) were measured by mating experiment. The levels of serum testosterone(T), estradiol(E_2), follicle stimulating hormone(FSH), luteinizing hormone(LH), and gonadotropin releasing hormone(GnRH) were measured by radioimmunoassay. The wet weights of testis and seminal vesicle were measured. The content of fructose in seminal plasma was detected by UV spectrophotometry. The pathological changes of testis and epididymis were observed by HE staining. The expression levels of transforming growth factor(TGF-β1) and cytochrome P450 aromatase(CYP19) in testis were detected by immunohistochemistry and Western blot. The results showed that Wubi Shanyao Pills could significantly reduce the score of kidney-Yang deficiency syndrome, improve the symptoms of kidney-Yang deficiency syndrome, shorten capture, straddle and ejaculation latency, increase capture and straddle times, increase serum T, LH, FSH, E_2 and GnRH levels, increase the wet weight of testis and seminal vesicle and fructose content in seminal plasma, improve the pathological structure of testis and epididymis, and inhibit the expression of TGF-β1 and increase CYP19 in testis of the model rats. Therefore, Wubi Shanyao Pills can significantly improve sexual dysfunction in rats with kidney-Yang deficiency, and its mechanism may be related to regulating the low function of hypothalamus pituitary gonad(HPG) axis and improving the disorder of sex hormone secretion. In addition, it may be also related to inhibiting the expression of testicular TGF-β1, increasing the expression of CYP19 protein, and then regulating the amount of T converted to E_2.

ABSTRACT

OBJECTIVES: We aimed to evaluate the effect of insulin resistance (IR) on serum Intelectin-1 and endocrinological hormones levels in obese and non-obese women with and without polycystic ovary syndrome (PCOS) in Basrah, Iraq.METHODS: From 124 women volunteers, 60 patients with primary and 64 patients with secondary, while 56 normal ovulatory women were taken as controls. Their fasting insulin hormone, intelectin-1, anti-Mullerian hormone, luteinizing hormone (LH), follicle stimulating hormone (FSH), prolactin (PRL), estradiol (E2) and testosterones (T) were determined by ELISA methods. BMI, glucose and quantitative insulin sensitivity check index as well as IR was determined by the homeostasis model assessment.RESULTS: A significant changes (P<0.05) were seen in the level of homeostasis model assessment-IR, E2 and T. Levels of anti-Mullerian hormone, LH, LH/FSH ratio and prolactin were significantly (P<0.01) increased and level of intelectin-1 and E2/T ratio were significantly (P<0.01) decreased, while quantitative insulin sensitivity check index level was not significantly different (P>0.05) between the patients (1°PCOS and 2°PCOS) and control groups. On the other hand, our data reported that FSH level was significantly (P<0.05) lower in obese and higher in non-obese patients with PCOS as compared to control group.CONCLUSION: Levels of intelectin-1 and endocrinological hormones have significantly associated with body mass index, IR and physical activity in patients and normal groups and the strategies that can modulate levels of these parameters would improve metabolic disarrangements in women with PCOS.

ABSTRACT

OBJECTIVE@#To study the association of body fat ratio with precocious puberty in girls. Previous studies have shown that body mass index (BMI) is associated with the girls' age of puberty but have not revealed the association of body fat ratio with age of puberty.@*METHODS@#Based on the consensus on the diagnosis and treatment of central precocious puberty (CPP), 128 children with precocious puberty who were admitted to the hospital from July to August, 2017, were divided into a CPP group with 87 children and a peripheral precocious puberty (PPP) group with 41 children. A total of 51 girls without any puberty development signs were enrolled as the control group. Dual-energy X-ray absorptiometry was used to measure the body fat ratios of upper limbs, legs, trunk, android area, gynoid area, and the whole body. The association between body fat ratios and precocious puberty was analyzed with reference to age, BMI, BMI-Z score, bone age, ovarian volume, and hormone levels.@*RESULTS@#Compared with the control group, the CPP and PPP groups had significantly higher body fat ratios of upper limbs, legs, trunk, android area, gynoid area, and the whole body, legs/whole body fat ratio, and (upper limbs+legs)/trunk fat ratio (P0.05). For the girls with precocious puberty, the high body fat ratio group had significantly higher luteinizing hormone (LH) base value, luteinizing hormone releasing hormone (LHRH)-stimulated LH peak value, and LH/follicle-stimulating hormone peak value than the low body fat ratio group (P<0.05). Compared with the control group, both the high body fat ratio and low body fat ratio groups had a significantly higher LH base value (P<0.05).@*CONCLUSIONS@#The increase in body fat may be a factor inducing precocious puberty in girls, but further studies are needed to determine the mechanism.

ABSTRACT

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.

ABSTRACT

ABSTRACT Introduction: The main cause of slightly elevated human chorionic gonadotropin (HCG) after successful treatment of male germ cell tumors is considered to be pituitary-derived HCG. It is well known that pituitary-derived HCG is frequently detected in postmenopausal women. We evaluated the status of serum HCG in men with elevated gonadotropins, which were induced by androgen deprivation therapy, using commercially available assays. Materials and Methods: We enrolled 44 patients with prostate cancer, who underwent luteinizing-hormone releasing hormone agonist treatment. We measured serum follicle-stimulating hormone (FSH), serum luteinizing hormone (LH), serum total HCG, serum free HCG-β subunit, and urine total HCG 3 times per patient, on the day of treatment initiation, the next day, and 3 months after. Results: On the day after treatment initiation, serum and urine HCG was detected in 61% and 73% of patients, respectively. Markedly strong correlations were observed between serum/urine HCG and FSH/LH. In particular, receiver operating characteristic curve analysis indicated excellent area under the curve (0.977, 95% confidence interval 0.951-1.003)) for serum HCG-detectable LH. At the cutoff value of 21.07 mIU/mL for serum HCG-detectable LH, the sensitivity and specificity were 96.7% and 95.3%, respectively. Serum HCG-β was not detectable at any times in any patients. Conclusions: Suggested pituitary-derived HCG can be frequently detected in patients with elevated gonadotropins, and there is a firm association between HCG detection and gonadotropin levels.

ABSTRACT

PURPOSE: The aim of this study was to investigate the clinicopathological features of premature ovarian insufficiency (POI) associated with chromosomal abnormalities. MATERIALS AND METHODS: This was a retrospective study of POI patients with chromosomal abnormalities diagnosed between January 2009 and December 2017. The definition of POI is based on hypergonadotropinism of 40 or greater in follicle stimulating hormone (FSH) measurements at age 40 years or less. FSH was measured twice at least 4 weeks apart. Karyotyping using peripheral blood for chromosomal testing was conducted in all patients diagnosed with POI. We analyzed the clinical characteristics and genetic causes of patients who were diagnosed with POI. RESULTS: Forty patients were diagnosed with POI including 9 (22.5%) with identified chromosomal abnormalities. The mean age at diagnosis was 23.1±7.8 years (ranging between 14 and 39). Three patients did not experience menarche. The presenting complaints were short stature in one case, one case of amenorrhea with ambiguous external genitals, one case of infertility, and six related to menstruation such as oligomenorrhea or irregular rhythm. Turner syndrome was diagnosed in four cases, Xq deletion in one case, trisomy X in two cases, and 46,XY disorder of sexual development in two other patients. CONCLUSION: Patients diagnosed with POI carrying the same type of chromosomal abnormality manifest different phenotypes. The management protocol also needs to be changed depending on the diagnosis. A karyotype is indicated for accurate diagnosis and proper management of POI in patients, with or without stigmata of chromosomal abnormalities.
