What are the two primary functions of the male and female sex organs?

The primary functions of the male and female sex organs are centered around the production of gametes and hormones. In males, the testes produce sperm, which are the male gametes essential for reproduction. Alongside gamete production, the testes also secrete testosterone, a critical hormone involved in the development of male secondary sexual characteristics and reproductive functions.

In females, the ovaries are responsible for producing eggs, the female gametes, and they also secrete hormones such as estrogen and progesterone. These hormones play vital roles in regulating the menstrual cycle, fertility, and the development of female secondary sexual characteristics.

The other options relate to bodily functions that are not specific to the primary roles of sex organs. Maintenance of body temperature and blood pressure involves various physiological systems throughout the body, while the storage of nutrients and energy pertains more to metabolic processes involving other organs like the liver and adipose tissue. Filtration and excretion of waste are primarily functions of the kidneys and urinary system, not the reproductive system. Thus, the focus on gametes and hormones accurately reflects the essential roles of the male and female reproductive organs.
