Inhibin is a protein hormone produced by granulosa cells in the ovary.
Inhibin suppresses FSH synthesis in humans.
Females produce inhibin in the gonads, pituitary gland, placenta, corpus luteum, granulosa cells, and other organs, whereas men release it from Sertoli cells inside the testes.
Inhibin is a gonadal messenger that regulates FSH produced by the pituitary gland through negative feedback.
Inhibin regulates ovarian and testicular function.
Its paracrine actions in the uteroplacental unit are now employed to diagnose male and female infertility, as well as gynaecological and gestational disorders.
