We have characterized the in vivo actions of human wild-type FSH receptor (FSHR) overexpressed in Sertoli cells of transgenic (Tg) mice (TgFSHRwt) compared with transgenic overexpression of the human activated mutant FSHR*D567G (TgFSHR*D567G). Testicular TgFSHRwt expression significantly elevated specific FSH binding (>2-fold, P < 0.01) relative to nontransgenic testes, similar to increased FSH...

OBJECTIVE To identify baseline characteristics of women with unexplained infertility to determine whether treatment with an aromatase inhibitor will result in a lower rate of multiple gestations than current standard ovulation induction medications. DESIGN Randomized, prospective clinical trial. SETTING Multicenter university-based clinical practices. PATIENT(S) A total of 900 couples wit...

OBJECTIVE Leptin is an adipocyte-derived hormone, which is the product of the obese gene and it is thought to play important roles in pubertal development and maintenance of reproductive function in the female. In a study using adult male or female rats, it was found that leptin stimulated the secretion of gonadotropin directly from the pituitary in a dose-related manner. However, there is no s...

The current experiment was aimed to explore the influencing of sex-linked dwarf gene on some fertility hormones and biochemical profile in normal local roosters. Thirty roosters at age 28 weeks were housed opened system for 6 weeks. At end 6th week, blood samples collected from all centrifuged obtained sera measuring concentrations Interstitial cell stimulating hormone 'ICSH', Follicle 'FSH' te...

The quality of sperm ejaculated by bonnet monkeys and normal, healthy proven fertile volunteer men, both actively immunized with ovine follicle-stimulating hormone (oFSH), was examined at different times of study for chromatin packaging and acrosomal glycoprotein concentration by flow cytometry. Susceptibility of sperm nuclear DNA to dithiothreitol (DTT)-induced decondensation, as measured by e...

BACKGROUND In the recent years, the use of laboratory blood factors such as FSH and inhibin-B for the assessment of spermatogenesis in different studies has increased; of course, the conflicting results have also been achieved. OBJECTIVE To investigate if the measurement of inhibin-B can help surgeon to reduce unnecessary diagnostic testicular biopsies in males with azoospermia. MATERIALS A...

BACKGROUND Leptin, which is the product of the obese gene, is believed to play important roles in pubertal development and reproductive function in females. In a study using adult male rats, it was found that leptin stimulated secretion of gonadotropin from the pituitary in a dose-related manner. However, there has been no such study in female rats. OBJECTIVE To investigate the effects of lep...

OBJECTIVE To study the value of measuring serum luteinising hormone (LH), follicle stimulating hormone (FSH), testosterone, and dihydrotestosterone (DHT) in androgen insensitivity syndrome (AIS). DESIGN Retrospective study of patients on a nationwide register of AIS. PATIENTS Sixty one cases of AIS with androgen receptor (AR) dysfunction (abnormalities of the AR gene and/or abnormal AR bind...

Infertility is considered a medical condition in which the population suffers. It has several causes, including hormonal disturbance and its effect on altering sperm parameters. This study was designed to estimate level of hormones (Testosterone, Luteinizing Hormone (LH), Follicle-Stimulating (FSH) Prolactin) for infertility group, potential these variables semen The included 50 men who were se...

Exposure to elemental mercury (Hg) vapour results in an accumulation of Hg in the pituitary, the thyroid, and the testis. In this study, basal serum concentrations of pituitary hormones (thyrotrophin (TSH), prolactin (PRL), follicle stimulating hormone (FSH), and luteinising hormone (LH] or their response after administration of thyrotrophin and gonadotrophin releasing hormones did not differ b...
