Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R. Assertion A: FSH acts upon ovarian follicles in female and Leydig cells in male. Reason R: Growing ovarian follicles secrete estrogen in female while interstitial cells secrete androgen in male human being. In the light of the above statements, choose the correct answer from the options given below:
Answer: (C) A is false but R is true. Answer: (c) A is false but R is true Solution: Assertion A is FALSE: FSH acts on the ovarian follicles in females, but in males it is LH (not FSH) that acts on the interstitial Leydig cells to stimulate androgen secretion; FSH in males regulates spermatogenesis along with androgens.
- A.Both A and R true but R is NOT the correct explanation of A.
- B.A is true but R is false
- C.A is false but R is true✓
- D.Both A and R are true and R is the correct explanation of A.
Correct Answer
(C) A is false but R is true
Solution & Explanation
Answer: (c) A is false but R is true Solution: Assertion A is FALSE: FSH acts on the ovarian follicles in females, but in males it is LH (not FSH) that acts on the interstitial Leydig cells to stimulate androgen secretion; FSH in males regulates spermatogenesis along with androgens. Reason R is TRUE: growing ovarian follicles secrete estrogen in females, and the interstitial (Leydig) cells secrete androgen in males. Hence A is false but R is true. NCERT Reference: Chapter 19, Page 241, Line(s) 41-46 — "In males, LH stimulates the synthesis and secretion of hormones called androgens from testis... FSH stimulates growth and development of the ovarian follicles in females."
