Related to inhibin: GnRH

in·hib·in

(in-hib'in),
One of several proteins that participate in differentiation and growth. Two glycoproteins, inhibin A and inhibin B, are secreted by Sertoli cells in the testis and granulosa cells in the ovary, inhibiting FSH secretion by direct action on the pituitary.
[inhibit + -in]

inhibin

(ĭn-hĭb′ĭn)
n.
A peptide hormone secreted by the follicular cells of the ovary and the Sertoli cells of the testis that inhibits secretion of follicle-stimulating hormone from the anterior pituitary.

inhibin

[inhib′in]
a gonadal hormone that inhibits activity of the follicle-stimulating hormone secreted by the anterior pituitary gland.

inhibin

A hormone that inhibits secretion of the FOLLICLE-STIMULATING HORMONE (FSH) by the pituitary gland. It is produced by the Sertoli cells of the seminiferous tubules in the male and by the granulosa cells of the ovaries in females.

inhibin

a nonsteroid hormone originating in the seminiferous tubules and ovarian follicles and which regulates follicle-stimulating hormone secretion.
