2024 Human ReproductionHormonal Regulation of Gametogenesis (FSH action) Medium Question 14 of 116 in Human Reproduction

Assertion A: FSH acts upon ovarian follicles in female and Leydig cells in male.

Reason: Reason R: Growing ovarian follicles secrete estrogen in female while interstitial cells secrete androgen in male human being.
A Both A and R are true and R is the correct explanation of A
B Both A and R are true but R is NOT the correct explanation of A
C A is true but R is false
D A is false but R is true

The answer is D.

Solution

Assertion: In males, FSH acts on the Sertoli cells (not Leydig cells) and stimulates secretion of factors that help in spermiogenesis; LH acts on the Leydig cells. So the Assertion is false. Reason: Growing ovarian follicles secrete estrogen in females, while interstitial (Leydig) cells secrete androgens in males – true. So A is false but R is true.
