What are the primary functions of the ovaries and testes in the endocrine system?

The correct response is centered on the role that both ovaries and testes play in the endocrine system, particularly concerning reproduction. The primary function of the ovaries is to produce female gametes (eggs) and secrete hormones such as estrogen and progesterone, which are essential for regulating the menstrual cycle, ovulation, and preparing the body for potential pregnancy. Similarly, the testes produce male gametes (sperm) and secrete testosterone, which is vital for the development of male reproductive tissues, secondary sexual characteristics, and overall reproductive functionality.

The focus on hormones necessary for reproduction highlights the pivotal nature of the ovaries and testes in sexual differentiation, fertility, and the maintenance of reproductive health across different life stages.
