What do human testes produce?

• A. Spermatozoa.
• B. Eggs.
• C. Hormones.
• D. Semen.

Answer: (A)

Spermatogenesis in the testes produces spermatozoa, the male gametes. This process occurs in the seminiferous tubules and results in haploid sperm that mature and travel through the reproductive tract. Eggs are made in the ovaries, not the testes. Semen is the fluid that carries sperm and is produced by accessory glands, not by the testes alone. The testes do secrete hormones such as testosterone, but the direct cellular product they generate—the one most directly answers the question about what they produce—is spermatozoa.
