Question

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 :

Options

A.A is true but R is false
B.A is false but R is true
C.Both A and R are true and R is the correct explanation of A
D.Both A and R are true but R is NOT the correct explanation of A

Solution

Sol. [Key Concept: FSH and LH target cells]

The assertion is false: FSH acts on ovarian follicles in females and Sertoli cells in males; LH acts on Leydig cells and stimulates androgen secretion. The reason is true: growing follicles secrete oestrogens, while testicular interstitial or Leydig cells secrete androgens. Hence, option (2).
