Serum FSH and LH levels were estimated by radioimmunoassay following single subcutaneous administration, and repeated subcutaneous administration at various intervals in immature male rats. Single injection of LH-RH induced slight increase in FSH levels in comparison with considerable increase in LH. By two successive injections, the release of FSH was markedly stimulated when the time interval...

BACKGROUND Protocols of controlled ovarian hyper-stimulation (COH) require, as a crucial step, the identification of reliable predictors of ovarian reserve. Anti-Mullerian hormone (AMH) is one of the most reliable predictors of ovarian reserve but other factors including autoimmune thyroid diseases (ATD) have been associated with reduced fertility and poor COH outcome. Aim of the present study ...

The concentrations of serum homovanillic acid (HVA), luteinizing liormone (LH), follicle-stimulating hormone (FSH) and testosterone (T) were examined in 20 male schizophrenic patients not taking neuroleptic drugs, 44 treated with neuroleptic drugs, and 15 male healthy control subjects. Kurskal-Wallis analysis of variance showed no significant difference among the three groups in serum HVA, FSH,...

BACKGROUND Human chorionic gonadotropin (hCG) tests are performed on many female patients before performing medical procedures or administering medications that may harm a fetus. hCG of pituitary origin has been shown to increase with age. Therefore, mild increases in serum hCG in an older patient can be of pituitary origin and does not necessarily indicate pregnancy. The inability to rule out ...

CONTEXT The Stages of Reproductive Aging Workshop proposed bleeding and hormonal criteria for the menopausal transition, but operational definitions of hormone parameters were not specified. OBJECTIVE This paper investigates the longitudinal relationship of annual serum FSH levels with four proposed bleeding criteria for the late menopausal transition in two cohort studies. The goal is to pro...

BACKGROUND Diabetes induces great alterations in female reproductive function. We analyzed the effects of tungstate, an anti-diabetic agent, on the reproductive function of healthy and diabetic female rats. METHODS Healthy and streptozotocin-induced diabetic rats were treated with sodium tungstate (2 mg/ml in their drinking water) for 12 weeks. Markers of reproductive function and diabetes we...

BACKGROUND Assessment of ovarian reserve is one of the steps in the management of infertile couples. Follicle Stimulating hormone (FSH) and anti-Müllerian hormone (AMH) are commonly used ovarian reserve markers in Africa. However, there is paucity of age-specific reference values for FSH and AMH among the African population. OBJECTIVE This study aimed at conducting a pilot study for generatio...

Follicle-stimulating hormone (FSH) in the organism together with LH is responsible for follicular growth and maturation of eggs. If the ovaries are not working, FSH levels rise. The most common reason for high serum FSH concentration is in a female who is undergoing or has recently undergone menopause. High levels of follicle-stimulating hormone indicate that the normal restricting feedback fro...

Activity of alkaloid extract of caricapryl-99 seeds [Carica papaya Linn seeds] on the serum levels of steroid hormones was studied in adult male albino rats. Three tolerated doses obtained from the graph of percentage toxicity [10, 50 and 150 mg/kg] were separately administered orally, daily for three days to three groups of male rats [n=5] while group four of 5 rats received the vehicle [corn ...
