The ovaries are oval shaped and about the size of a large grape. They are located on opposite ends of the pelvic wall, on either side of the uterus.
The ovaries are each attached to the fimbria tissue that connects the ovaries to the fallopian tube. Ovaries produce and release two groups of sex hormones—progesterone and estrogen. There are actually three major estrogens, known as estradiol, estrone, and estriol. These substances work together to promote the healthy development of female sex characteristics during puberty and to ensure fertility.

Estrogen estradiol, specifically is instrumental in breast development, fat distribution in the hips, legs, and breasts, and the development of reproductive organs. To a lesser extent, the ovaries release the hormone relaxin prior to giving birth. Another minor hormone is inhibin, which is important for signaling to the pituitary to inhibit follicle-stimulating hormone secretion.
