Pulsatile LH release is diminished, whereas FSH secretion is normal, in hypocretin-deficient narcoleptic men.
Hypocretin (orexin) peptides are involved in the regulation of energy balance and pituitary hormone release. Narcolepsy is a sleep disorder characterized by disruption of hypocretin neurotransmission. Pituitary LH secretion is diminished in hypocretin-deficient animal models, and intracerebroventricular administration of hypocretin-1 activates the hypothalamo-pituitary-gonadal axis in rats. We ...
متن کاملCirculating Inhibin A and Inhibin B in Normal Menstrual Cycle during Breeding Seasons of Japanese Monkeys
In order to clarify the endocrinological profiles of inhibins during normal menstrual cycles in Japanese monkeys, plasma concentrations of inhibin A and inhibin B were measured by enzymelinked immunosorbent assay. In addition, circulating gonadotropins and steroid hormones were measured. Blood samples were taken from four Japanese monkeys showing normal menstrual cycles. Plasma inhibin A remain...
متن کاملSerum inhibin levels in normal men and men with idiopathic infertility.
In vitro studies have shown that the Sertoli cell is the primary source of inhibin in the male. To assess the regulation of inhibin production we measured serum inhibin, FSH, LH and testosterone in 21 normal men and 104 men with various testicular disorders resulting in infertility. The infertile men were subdivided into groups on the basis of their mean sperm count, FSH and LH levels. The mean...
متن کاملSerum Inhibin B as a Marker of Spermatogenesis
Inhibin B is produced by Sertoli cells, provides negative feedback on FSH secretion, and may prove to be an important marker for the functioning of seminiferous tubules. The purpose of the present study was to examine the relationship between the spermatogenic function of the testis of subfertile men and the plasma concentrations of inhibin B and FSH. These parameters were estimated in a group ...
متن کاملInhibin is an important factor in the regulation of FSH secretion in the adult male hamster.
We investigated the importance of inhibin and testosterone in the regulation of gonadotropin secretion in adult male golden hamsters (Mesocricetus auratus). After castration, plasma concentrations of inhibin and testosterone were reduced to undetectable, whereas plasma follicle-stimulating hormone (FSH) and luteinizing hormone (LH) were increased. After hemicastration, plasma FSH and LH increas...
