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 ...
متن کاملInteraction of estradiol and luteinizing hormone releasing hormone on follicle stimulating hormone release in cattle.
To study the mechanism by which estradiol induces a preovulatory surge of follicle stimulating hormone (FSH), we concluded experiments designed to determine: (1) the time course of change in luteinizing hormone releasing hormone (LHRH)-induced FSH release after estradiol in vivo, and (2) whether LHRH is required to trigger the FSH surge. Steers were given 1 microgram LHRH at 20-min intervals fo...
متن کاملControl 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...
متن کاملIsolation of the luteinizing hormone and follicle-stimulating hormone-releasing hormone from porcine hypothalami.
A new procedure is described for the isolation on a preparative scale of a hypothalamic decapeptide which stimulates the release of both luteiaizing hormone (LH) and folliclestimulating hormone (FSH) from the pituitary. The isolation was achieved mainly by countercurrent distribution. The yield from 240,000 porcine hypothalami was 11.4 mg. Thin layer chromatography and electrophoresis showed th...
متن کاملUse of clomiphene and luteinizing hormone/follicle stimulating hormone-releasing hormone in investigation of ovulatory failure.
A luteinizing hormone/follicle-stimulating hormone-releasing hormone (LH/FSH-RH) test was performed in 70 women with amenorrhoea or anovulatory infertility, or both, and a clomiphene stimulation test was also performed in 24 of these patients. Most patients responded to LH/FSH-RH with significant increases in LH and FSH. In women with gonadal dysgenesis or premature ovarian failure exaggerated ...
