Effects on the Secretion of Pituitary Growth Hormone, Thyroid Stimulating Hormone, Luteinizing Hormone and Follicle Stimulating Hormone in Rats Rendered Hyperprolactinaemic by Chronic Treatment with Oestrogen

Can fasting in the holy month of Ramadan affect on the levels of luteinizing hormone, follicle-stimulating hormone, and prolactin?

Adherence to the recommendations and obligations of Islam is of great importance in achieving a desirable lifestyle. Fasting in the holy month of Ramadan is one of the main principles of Islam, in which Muslims refrain from eating, drinking, oral medications, and smoking from Fajr (pre-dawn) to Maghrib (sunset). Islamic rules dictate that fasting is unacceptable if it causes harm to the health ...

Control of gonadotropin secretion by follicle-stimulating hormone-releasing factor, luteinizing hormone-releasing hormone, and leptin.

Fractionation of hypothalamic extracts on a Sephadex G-25 column separates follicle-stimulating hormone-releasing factor (FSHRF) from luteinizing hormone-releasing hormone (LHRH). The FSH-releasing peak contained immunoreactive lamprey gonadotropin-releasing hormone (lGnRH) by radioimmunoassay, and its activity was inactivated by an antiserum specific to lGnRH. The identity of lGnRH-III with FS...

Dissociation of human follicle-stimulating hormone. Comparison with luteinizing hormone.

Rat testis tissue receptor assays were utilized to study the kinetics of dissociation of human follicle-stimulating hormone (hFSH) and luteinizing hormone (hLH) under varying conditions of urea concentration and pH. In these competitive protein binding assays, 125I-hFSH and 125I-hLH were the radioligands and hormone dissociation was followed by a decrease in the ability of the dissociating horm...

Protective effect of vitamin D on Luteinizing Hormone (LH), Follicle-Stimulating Hormone (FSH), testosterone hormones and testicular tissue changes induced by methotrexate in adult male rats

Background and Aims: Vitamin D has antioxidant and anti-inflammatory activities. The present study aimed to investigate the protective effect of vitamin D on Luteinizing Hormone (LH), Follicle-Stimulating Hormone (FSH), testosterone hormones and testicular tissue changes induced by methotrexate in adult male rats. Materials and Methods: In this experimental study, 30 adult male Wistar rats wei...
