where is a gonad
Female gonad: The female gonad, the ovary or egg sac, is one of a pair of reproductive glands in women. They are located in the pelvis, one on each side of the uterus. Each ovary is about the size and shape of an almond. The ovaries have two functions: they produce eggs (ova) and female hormones. Each month, during the menstrual cycle, an egg is released from one ovary. The egg travels from the ovary through a fallopian tube to the uterus. The ovaries are the main source of female hormones (estrogen and progesterone).
Male gonad: A testis, one of a pair of organs located behind the penis in a pouch of skin called the scrotum. The testes produce and store sperm and are also the body's main source of male hormones. These hormones control the development of the reproductive organs and other male characteristics, such as body and facial hair, low voice, and wide shoulders. Last Editorial Review: 5/13/2016.
