gonads produce
sex cells, or gametes, and secretes sex hormones
Gonads are the primary reproductive organs in both males and females, and they are responsible for producing gametes (sperm cells in males and ova or eggs in females) and sex hormones.
In males, the gonads are called testes or testicles, and they produce the male sex hormone testosterone, which is responsible for the development of male secondary sexual characteristics such as body hair, muscle mass, and deeper voice. The testes also produce and store millions of sperm cells every day, which are released during ejaculation to fertilize a female egg.
In females, the gonads are called ovaries, and they produce the female sex hormones estrogen and progesterone, which are responsible for the development of female secondary sexual characteristics such as breast development, wider hips and menstrual cycle. The ovaries also release one mature egg every month during ovulation, which can be fertilized by a sperm cell to form a zygote that will develop into a fetus.
