Answer 1

The correct statement concerning the cells of Leydig is that they become functional at puberty.

Step-by-step explanation:

The correct statement concerning the cells of Leydig is:

(A) They become functional at puberty.

Leydig cells are located in between the walls of the seminiferous tubules in the testes. They are stimulated by luteinizing hormone (LH) to produce and release testosterone into the testes and the blood. Testosterone plays a key role in the development of secondary sexual characteristics in males and the maturation of the reproductive system during puberty.
