Which body system is primarily involved in producing sperm cells?

• A. Digestive system
• B. Respiratory system
• C. Reproductive system
• D. Nervous system

Answer: (C)

The reproductive system is responsible for producing sperm cells. In males, sperm production, or spermatogenesis, occurs mainly in the testes within the seminiferous tubules. This process is driven by hormones from the pituitary (FSH and LH) and testosterone, leading germ cells to divide and mature into sperm. Once formed, sperm move to the epididymis to mature further and be stored. Other body systems handle digestion, breathing, and signaling, but they don’t directly generate sperm.
