QUESTION
Testosterone is produced by?
OPTIONS
(A) Leydig cells
(B) Granulosa cells
(C) Sertoli cells
(D) Germinal cells
ANSWER
(A) Leydig cells
EXPLANATION
Leydig cells in the testicular interstitium synthesize testosterone in response to LH stimulation. Sertoli cells support developing germ cells and produce substances such as inhibin and androgen-binding protein. Germinal cells develop into spermatozoa rather than serving as the principal androgen source. Granulosa cells belong to ovarian follicles and mainly participate in estrogen synthesis and later luteal differentiation.
