Puberty in the Male Chimpanzee: Time-Related Variations in Luteinizing Hormone, Follicle-Stimulating Hormone, and Testosterone1

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 ...

Testosterone regulation of luteinizing hormone and follicle stimulating hormone secretion in young male lambs.

Polydimethylsiloxane (Silastic) capsules containing crystalline testosterone were implanted subcutaneously in castrate lambs and evaluated for their ability to (1) provide stable, physiological concentrations of serum testosterone and (2) regulate secretion of LH and FSH. Testosterone was nondectable (< .2 ng/ml) between 12 and 24 weeks of age in the serum of castrate lambs implanted with empty...

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...

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...
