Question: 157. 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 :
(1) Both A and R are true and R is the correct explanation of A .
(2) Both A and R are true but R is NOT the correct explanation of A .
(3) A is true but R is false.
(4) A is false but R is true.
Answer: Option (4)
Explanation:
In females, follicle stimulating hormone acts on the ovarian follicles and stimulates their growth and estrogen secretion.
In males, follicle stimulating hormone does not act on Leydig cells; instead, it acts on Sertoli cells to stimulate spermatogenesis.
Leydig cells are stimulated by luteinizing hormone and secrete androgens such as testosterone.
The reason statement is correct because growing ovarian follicles secrete estrogen in females and interstitial (Leydig) cells secrete androgens in males.
Therefore, the assertion is false while the reason is true,
making option (4) the correct answer.
