Why do women need progesterone supplementation?
Progesterone is an important hormone for pregnancy. It helps thicken the lining of the uterus (called the endometrium) for implantation of a fertilized egg. Progesterone also helps sustain pregnancy after implantation. (See Progesterone’s Role in Pregnancy for more information.)
Some women may experience a progesterone deficiency/inadequacy that makes it more difficult for them to become pregnant or to maintain pregnancy.
A progesterone deficiency/inadequacy can be caused by 1 of 2 factors:
- The ovaries produce little to no progesterone
- The endometrium is not responding to normal levels of progesterone
