Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R.

Assertion A: Leydig cells synthesise and secrete male testicular hormones called androgens.

 Reason R: Androgens, stimulate the process of spermatogenesis.

In the light of the above statements, choose the most appropriate answer from the options given below:

Both A and R are correct and R is NOT the correct explanation of A

The correct answer is Option (2): Both A and R are correct and R is NOT the correct explanation of A

Assertion A: Leydig cells synthesise and secrete male testicular hormones called androgens. True. Leydig cells (also known as interstitial cells) are located in the connective tissue between the seminiferous tubules. Their primary function is to produce and secrete androgens, the most well-known being testosterone.

Reason R: Androgens, stimulate the process of spermatogenesis. True. Androgens are essential for the maturation and production of sperm cells. They act on the Sertoli cells within the seminiferous tubules to provide the necessary environment for spermatogenesis to occur.

Why R is NOT the correct explanation of A?

Reason R is not the correct explanation of Assertion A because it only describes one function of androgens, namely stimulation of spermatogenesis. Assertion A states that Leydig cells synthesise and secrete androgens, which is a fact about the source of these hormones. The reason does not explain why Leydig cells produce androgens or how they are involved in their secretion. Instead, it tells what androgens do after being produced. Therefore, both statements are individually correct, but R does not logically explain A.
