Which organ is the male gonad?

• A. Ovaries
• B. Prostate
• C. Testes
• D. Epididymis

Answer: (C)

The testes are the organs that produce the gametes and the primary sex hormone in males. They are the male gonads, responsible for making sperm in the seminiferous tubules and for secreting testosterone from Leydig cells, which drives male development and characteristics. The ovaries perform the same role for females, producing eggs and hormones. The prostate is an accessory gland that adds fluid to semen, not a gonad, and the epididymis stores and helps mature sperm after they are formed in the testes.
