The Role of Progesterone During Pregnancy

Progesterone plays many vital roles in pregnancy. It helps to keep the uterus thick and healthy, and it is also responsible for the production of relaxin, an important hormone that helps to relax the ligaments in the body so that the baby can more easily pass through during birth.

Progesterone also helps to prevent the uterus from contracting during pregnancy. This is important for a healthy mother and baby as it helps to avoid preterm labor. Furthermore, progesterone helps to protect the baby from the mother’s immune system, ensuring a successful and healthy pregnancy.
