A woman's two ovaries are located on both sides of the uterus, just below the opening of the fallopian tubes (tubes that extend from the uterus to the ovaries).
In addition to producing egg cells, the ovaries produce estrogen and progesterone, which affect many of the female characteristics and reproductive functions. Estrogens are also responsible for good bone health and strength. The levels of secreted estrogen and progesterone are controlled by gonadotropic hormones produced by the pituitary gland. The ovaries also contain the egg cells necessary for reproduction.
The two testes are oval-shaped organs that hang suspended in a pouch of skin (scrotum) outside the male body.
The testes in a man produce testosterone and other hormones, which affect many of the male characteristics and support sperm production. Testosterone is also responsible for good bone health and strength in men.
