Inhibin is a protein mainly produced by the gonads.
In men it is produced by the Sertoli cells and it is produced by the granulose cells in women.
It negatively regulates the secretion of Follicle Stimulating hormone (FSH) from the pituitary gland.
FSH itself induces the production of inhibin for negative feedback.
Pituitary is a pea shaped endocrine gland present at the base of the brain. It is the major endocrine gland and controls growth, development and functions of other endocrine glands.
Hormone activin has opposite effect to inhibin. It enhances FSH biosynthesis and secretion.
