Final answer:
The reproductive system is responsible for producing and fertilizing gametes and carrying a fetus. Gonads produce gametes and sex hormones, which control the development of sex organs and reproduction.

The reproductive system is the human organ system responsible for the production and fertilization of gametes (sperm or eggs) and carrying of a fetus. Both sexes have gonads (testes in men and ovaries in women) that produce gametes and sex hormones. Sex hormones control the development of sex organs, sexual maturation at puberty, and reproduction after puberty.
