Below the fallopian tubes, an extension of the uterus, are two ovaries, located on both the left and right side of the tubes. The ovaries produce an egg, for reproductive matters, about once a month, although this may vary from person to person and condition to condition. These two glands are also responsible for production of reproductive hormones, such as estrogen and progesterone. The secretion of these hormones are also controlled by gonadotropic hormones secreted by the pituitary gland. [An entire list of human glands]
The testes are oblong/oval-shaped sacs that are suspended from a mass of tissue, located beneath the base of the penis. Unlike female ovaries, testes are located outside of the male human body. The testes are responsible for producing testosterone, which accounts for male ambition/drive and sperm production. However, testosterone production varies from person to person, and their overall health.
