Inhibin inhibits the secretion of FSH only.
<h3>What is the role of inhibin?</h3>
- 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.
