Estrogen and progesterone are steroid hormones that play an important role in regulating mammalian reproduction. They regulate the development and functioning of the uterus. They act by regulating the transcription of certain genes in the uterus.
Estrogen is the hormone that regulates the menstrual cycle while progesterone is the hormone that supports pregnancy. During pregnancy, these two work together and are responsible for the changes that take place during pregnancy.

| Estrogen | Progesterone |
| Estrogen is a female hormone secreted by ovaries prior to ovulation. |
Progesterone is a female hormone that is secreted by ovaries after ovulation

Luteinizing hormone (LH) largely controls the secretion of progesterone
|
| During pregnancy, it induces enlargement of breasts and uterus |
During pregnancy, it reduces contractility of the uterus and stimulates the growth of mammary glands. It also induces the growth of decidual cells.
|
| Growing Grafian follicle produces estrogen |
Corpus luteum produces progesterone
