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.

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.
