Which is a primary function of the reproductive system?

• A. Produce hormones and reproductive cells
• B. Regulate blood sugar
• C. Control digestion
• D. Oxygen transport

Answer: (A)

The main idea being tested is that the reproductive system’s primary role is to create reproductive cells and the hormones that regulate reproduction. The gonads—the testes and ovaries—produce gametes (sperm or eggs) and release sex hormones such as testosterone, estrogen, and progesterone. These hormones drive sexual development, maturation, and the reproductive cycles that make fertilization possible. In males, sperm production and testosterone support male reproductive function; in females, egg production and hormones coordinate the menstrual cycle and potential pregnancy. While other bodily systems handle tasks like regulating blood sugar, digestion, or oxygen transport, those functions belong to different systems, not the reproductive system.
