QUESTION
Testosterone hormone is produced from?
OPTIONS
(A) Leydig cells
(B) Medusa cells
(C) Spermatogonia
(D) Sertoli cells
ANSWER
(A) Leydig cells
EXPLANATION
Testosterone is synthesized mainly by Leydig cells located between the seminiferous tubules, under stimulation by luteinizing hormone. Spermatogonia are germ cells that initiate the sperm-producing lineage, and Sertoli cells provide support, nourishment, and regulatory secretions within the tubules. Medusa cells are not a recognized testicular endocrine cell population responsible for androgen synthesis.
