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 the correct explanation of A

The correct answer is Option (1): Both A and R are correct and R is the correct explanation of A

Spermatogenesis starts at the age of puberty due to significant increase in the secretion of gonadotropin releasing hormone (GnRH). This is a hypothalamic hormone.

The increased levels of GnRH then acts at the anterior pituitary gland and stimulates secretion of two gonadotropins – luteinising hormone (LH) and follicle stimulating hormone (FSH).

LH acts at the Leydig cells and stimulates synthesis and secretion of androgens. Androgens, in turn, stimulate the process of spermatogenesis.
