Question

In females, hormone inhibin is secreted by.

• A. Granulosa cells and corpus luteum
• B. Granulosa and theca cells
• C. Granulosa and cumulus oophorus cells
• D. Granulosa cells and zona pellucida

Answer 1

The correct option is A Granulosa cells and corpus luteum

• In both females and males, inhibin inhibits FSH production. Inhibin does not inhibit the secretion of GnRH from the hypothalamus.
• In females,

Inhibin is produced in the gonads, pituitary gland, placenta, corpus luteum, granulosa cells and other organs.

• In Males,

It is secreted from the Sertoli cells, located in the seminiferous tubules inside the testes. Androgens stimulate inhibin production; this protein may also help to locally regulate spermatogenesis. Hence, In females, hormone inhibin is secreted by Granulosa cells and corpus luteum

So, the correct answer is 'Granulosa cells and corpus luteum'.
