OBJECTIVE To study serum gonadotropin (FSH, LH) levels in cases of subclinical and overt hypothyroid women in reproductive age group. MATERIAL AND METHOD Female patients of reproductive age group attending thyroid clinic of Acharya Vinoba Bhave Hospital were included in the study. Detail menstrual history was taken, and serum FSH and LH levels were estimated by radio immuno assay method. RE...

OBJECTIVES The aim of this study was to evaluate ovarian function with longitudinal changes in serum levels of anti-mullerian hormone (AMH), follicle stimulating hormone (FSH) and estradiol (E2) after total abdominal hysterectomy (TAH) with ovarian conservation. MATERIAL AND METHODS In this prospective longitudinal study, a total of 29 women, aged 39 to 48 years, suffering from uterine pathol...

Background: Altered luteinizing hormone to follicle-stimulating (LH-FSH) ratio and hyperandrogenism are two important pathophysiological characteristics of polycystic ovary syndrome (PCOS). The aim this study was evaluate the relationship LH-FSH with androgen in women PCOS. Methods: This cross-sectional included 550 newly detected reproductive aged PCOS (mean ± standard deviation (SD): age 23.1...

The measurement of Follicle Stimulating Hormone (FSH) in human serum is essential for investigating fertility and especially disorders of the hypothalamic pituitary gonadal axis. Therefore, the present study aimed to prepare radioimmunoassay (RIA) system using solid phase magnetic particles for the invitro quantitative measurement of FSH in human serum. The preparation of polyclonal antibody (a...

The specific roles of luteinizing hormone (LH) and follicle-stimulating hormone (FSH) in controlling human spermatogenesis are poorly understood. We studied the effect of an experimentally induced, selective LH deficiency on sperm production in normal men. After a 3-mo control period, five men received 200 mg testosterone enanthate (T) i.m./wk to suppress LH, FSH, and sperm counts. Then, while ...

There is experimental evidence that a portion of follicle-stimulating hormone (FSH) secretion is independent of hypothalamic influences. A 29 year old woman with familial pure gonadal dysgenesis developed myelodysplastic syndrome. Endocrine investigations showed discrepancy between serum FSH and luteinizing hormone (LH) levels. FSH levels remained elevated while LH levels decreased. The FSH to ...

Aim was to determine if a serum levels of free testosterone and selected eight hormones are in correlation with potency and libido problems in aging male. Male population older then 45 years of two Slavonian villages was called for voluntary examination. Every patient filled a questionnaire concerning medical history, operations and potency and libido problems. Based on answers we formed six gr...

The mechanism governing the number of follicle-stimulating hormone (FSH) peaks and emerging follicular waves in ruminants remains unknown. The main purpose of the present study was to examine the relationships between progesterone (P(4)) levels, circulating concentrations of FSH and antral follicular development throughout the interovulatory interval in sheep. We retrospectively analyzed and co...

Changes in profiles of serum luteinizing hormone (LH), follicle stimulating hormone (FSH) and testosterone and in mating performance and ejaculate volume have been determined in Finnish Landrace (F inn)and Managra Synthetic (Line-M) rams during the ovine breeding season. In early August, mid-September, early November and mid-December four rams of each breed were bled by venipuncture from the ju...

To reveal the reproductive biology in male bottlenose dolphins (Tursiops truncatus), circulating gonadotropins (follicle stimulating hormone [FSH] and luteinizing hormone [LH]) and testicular hormones (testosterone and inhibin) were monitored for 8-12 years in 2 captive bottlenose dolphins (Mars and Regulus). During the study period, Mars was undergoing sexual maturation, whereas Regulus was al...
