Which structure produces testosterone and germinates sperm?

• A. Testes
• B. Prostate
• C. Epididymis
• D. Seminal vesicle

Answer: (A)

The testes are responsible for both testosterone production and sperm generation. The Leydig cells in the testes produce testosterone, a hormone that drives male sexual development and supports spermatogenesis. Sperm are produced in the seminiferous tubules, where germ cells undergo division and maturation under Sertoli cell support, a process called spermatogenesis. Other listed organs have different roles—prostate adds fluid to semen, epididymis stores and matures sperm, and the seminal vesicle supplies most of the seminal fluid. Since the testes handle both hormone production and sperm formation, they are the correct structure.
