Male reproductive organs that produce sperm and hormones, primarily testosterone?

• A. Vas Deferens
• B. Testes
• C. Gall Bladder
• D. Pancreas

Answer: (B)

A key idea here is that the male gonads are responsible for both making sperm and producing the main male hormone, testosterone. The testes are the primary male reproductive organs. Inside them, spermatogenesis occurs in the seminiferous tubules to generate sperm, while the interstitial Leydig cells produce testosterone. This testosterone supports the development and maintenance of male reproductive tissues and drives secondary sexual characteristics, and it also helps regulate sperm production. The other options don’t fulfill both roles: the vas deferens transports sperm, the gall bladder stores bile, and the pancreas makes digestive enzymes (and insulin). Therefore, the testes are the organ that handles both sperm production and testosterone synthesis.
