The Ovaries

The Ovaries


The Ovaries

The ovaries are a pair of organs in the female reproductive system. They are located in the pelvis, one on each side of the uterus. The uterus is the hollow, pear-shaped organ where a baby grows. Each ovary is about the size and shape of an almond. The ovaries produce eggs and female hormones. Hormones are chemicals that control the way certain cells or organs function.
Female anatomy
Every month, during a woman's menstrual cycle, an egg grows inside an ovary. It grows in a tiny sac called a follicle. When an egg matures, the sac breaks open to release the egg. The egg travels through the fallopian tube to the uterus for fertilization. Then the sac dissolves. The empty sac becomes Corpus luteum (A yellow, progesterone-secreting mass of cells that forms from an ovarian follicle after the release of a mature egg. ). Corpus luteum makes hormones that help prepare for the next egg.
The ovaries are the main source of the female hormones estrogen and progesterone. These hormones affect:
the way breasts and body hair grow
  • body shape
  • the menstrual cycle
  • pregnancy
