What hormones do the ovaries produce?

The ovaries are pretty tiny. A woman has a pair of ovaries and each one is only about the size of a large grape. Yet these remarkable little oval-shaped structures churn out several critical hormones—chemicals that travel around the body performing all sorts of jobs. The two main hormones made in the ovaries are estrogen and progesterone. These hormones regulate women's menstrual periods, among other things.
The ovaries produce the hormones estrogen and progesterone. Estrogen is needed for the normal development of the breasts and uterus. This sex hormone also controls ovulation (the period when women are most fertile) and is closely tied to many other aspects of a woman's health, including keeping bones strong and protecting against heart disease. Progesterone controls a woman's menstrual cycle.

Ovaries produce reproductive hormones, both estrogen and progesterone. These hormones regulate your monthly periods. Progesterone is the hormone that prepares your body for pregnancy. As these hormone levels begin to decline, your body will experience the changes of menopause.
