Inhibin production

Webb2 dec. 2024 · Inhibin is a hormone emitted by granulosa cells in the ovarian follicles and by Sertoli cells in the testis. 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 dec. 1994 · Inhibins and activins exhibit a broad spectrum of biologic activities, many of which affect the reproductive axis. Within the ovary and testis, the synthesis of the inhibin and activin α and β subunits is regulated by circulating hormones, such as the pituitary gonadotropins, and by diverse paracrine factors. Webb7 apr. 2024 · Inhibins suppress the FSH production in pituitary gonadotrope cells by robustly antagonizing activin signaling by competitively binding to activin type II receptors (ACTR II). The binding of inhibin A to ACTR II requires the presence of its co-receptor, namely, betaglycan.

WebbProduction of inhibin subunits by the Sertoli cell is indicated, with additional possible production of βB subunit by spermatocytes. The overall stimulatory influence of FSH is shown, together with the modulatory influence of the germ cell component, in particular the numbers of spermatocytes and/or spermatids.
