Question

Identify the correct statement with respect to ‘inhibin’.

• A. It is produced by granulosa cells in ovary and inhibits the secretion of estrogen.
• B. It is produced by nurse cells in testes and inhibits the secretion of progesterone in males.
• C. It inhibits the secretion of LH, FSH and prolactin.
• D. It is produced by corpus luteum and inhibits the secretion of FSH.

Answer 1

The correct option is D It is produced by corpus luteum and inhibits the secretion of FSH.

In females, the hormone inhibin is produced by the granulosa cells of the ovarian follicles and also to a small extent by the corpus luteum. It inhibits the production of FSH and LH. It doesn’t inhibit the secretion of prolactin, estrogen or progesterone.
In males, it is secreted by the nurse cells/ sertoli cells of the testes. In males too, it inhibits the production of FSH and LH. Hence, we see that option d is entirely correct.
