What is one of the primary functions of the gonads?

The primary function of the gonads, which include the ovaries in females and the testes in males, is to produce both gametes and sex hormones. Gametes are the reproductive cells; in males, these are sperm, and in females, they are eggs. In addition to gamete production, the gonads also secrete essential sex hormones, such as testosterone, estrogen, and progesterone, which play crucial roles in sexual development, reproductive functions, and the regulation of various bodily processes.

The production of gametes is vital for reproduction, while the hormones regulate secondary sexual characteristics and reproductive cycles. This dual function is fundamental to the reproductive system's overall operation and highlights the integrated roles of the gonads in both reproduction and endocrinology. Other options do not capture the full range of functions provided by the gonads. Some suggest only hormonal or gamete production, missing the comprehensive nature of gonadal roles.
