Its physiological role is to stifle secretion of follicle-stimulating hormone (FSH) by the pituitary. They are multifunctional particles engaged with the control of pituitary FSH secretion. Webb1 apr. 1988 · Inhibin has been defined as a gonadal hormone that exerts a specific negative feedback action on the secretion of FSH from the gonadotropic cells of the pituitary gland. The existence of inhibin was postulated as early as 1923 (250). rear window tinting costWebbGnRH (20 ng/ml) was more potent than rh-activin-A for LH secretion. Nevertheless, a significant increase in LH secretion into the medium was brought about by rh-activin-A.

WebbInhibins are mainly produced in the gonads and provide negative regulation of FSH secretion from the pituitary, but also have paracrine/autocrine actions in the gonads and adrenal gland. As they share the β-subunits with activins, the actions of inhibins are associated with their antagonism of activin signaling. Webb21 jan. 2024 · Inhibin is a glycoprotein hormone produced by normal ovarian granulosa cells and testicular sertoli cells. In the ovary, it inhibits the secretion of follicle-stimulating hormone. Patients with granulosa cell tumors (GCT) have elevated serum levels of inhibin and this finding has been used to detect recurrent tumor.
