Inhibin
Inhibin is a hormone found in the human body. It is secreted from the granulosa cells of the ovaries in females and from the sustentacular cells in males. Inhibin contains an alpha and beta subunit linked by disulfide bonds. It is classified as a peptide hormone.
Secretion and Production
Inhibin is produced in and secreted from the granulosa cells of the ovaries in females and the sustentacular cells in males. Follicle-stimulating hormone (FSH) stimulates the secretion of inhibin, and, in turn, inhibin suppresses FSH. FSH stimulates ovulation in females and spermatogenesis in males, therefore playing a major role in fertility.
There is currently no medical use for synthetic inhibin. Rather, many studies are conducted on how to immunize the inhibin hormone in infertility cases.
