Background: Polycystic ovarian disease (PCOD) is the commonest endocrine disorder affecting women at reproductive age. As a complex multisystem disorder, its background can be confusing to understand. The key feature an increased production of AMH by antral follicles. Aim: aim present study was assess threshold value serum in PCOD and correlation with other related hormones such as FSH, LH Prol...

BACKGROUND Testicular regulation of inhibin B may be influenced by the germ cell complement. METHODS We examined the effects of gonadotrophin stimulation on serum inhibin B and pro-alphaC in 25 normal men at (i) control (stimulation test 1), (ii) after spermatogenic suppression induced by testosterone plus progestin treatment (stimulation test 2), and (iii) during spermatogenic recovery induc...

AIM To examine the long term effect of bone marrow transplantation (BMT) on ovarian function in girls. METHODS Eighteen girls who underwent BMT before menarche, had been disease free for more than six years, and were over 14 years of age at the time of study were investigated. The preparative regimen consisted of irradiation and chemotherapy. The occurrence of menarche and changes in basal se...

Passive immunization of chronically ovariectomized gilts against gonadotropin releasing hormone (GnRH) resulted in an abrupt cessation of pulsatile secretion of luteinizing hormone (LH) accompanied by clearance from serum with a mean half-life of 30.9 +/- 2.3 (mean +/- SE) and 918 +/- 200 min for the first and second compartment, respectively. Serum follicle stimulating hormone (FSH) was unaffe...

Background It is important to evaluate ovarian reserves prior to intracytoplasmic sperm injection (ICSI) treatment. The aim of this study is to determine the accuracy of anti-mullerian hormone (AMH) as a marker for ovarian reserve and to compare it with day-3 serum follicle-stimulating hormone (FSH) levels. MaterialsAndMethods In this analytic, corss-sectional study, sequential sampling was don...

Background: To investigate the association between serum lipoprotein levels and insulin resistance in women with polycystic ovarian syndrome (PCOS). Methods: Twenty-five PCOS patients and twentyfive age-matched controls were enrolled in the study. Serum levels of luteinizing hormone (LH), follicle-stimulating hormone (FSH), fasting glucose (FBG), fasting insulin (FINS), serum triglycerides (TG)...

We have previously reported that Sertoli cells in culture secrete a transferrin-like protein (Skinncr and Griswold, 1980). The purpose of this study was to determine to what extent hormones such as follicle-stimulating hormone (FSH), insulin and testosterone, and vitamin A can regulate the amount of testicular transferrin secreted by cultured Sertoli cells. Sertoli cell culture medium was colle...

BACKGROUND The onset of sexual maturation at puberty is a unique developmental period from a neuroendocrine perspective in that it is characterized by enhanced FSH secretion and FSH responsiveness to exogenous GnRH (vs. LH) from the gonadotrope, yet the mechanism of these dynamics remains unclear. This study aimed to elucidate this phenomenon using a human disease model of GnRH deficiency (idio...

BACKGROUND Ovarian follicular activity in serial hormone profiles has been reported in up to 86% of patients with primary ovarian insufficiency (POI). In most of these studies, patients had a short duration of amenorrhea or irregular menstrual cycles which could influence the occurrence of spontaneous follicular activity. The aim was to study the incidence of follicular activity in serial hormo...

background: there are evidences regarding the prevalence of dysfunction in sexual function and behavior in diabetic people. experimental studies revealed a positive effect of withania somnifera on sexual function and behaviors. objective: in this research the effect of withania somnifera on sexual function in diabetic male wistar rats was assessed by measuring the serum levels of testosterone p...
