Progesterone is an important hormone that plays a key role in the female menstrual cycle and pregnancy. Progesterone is produced mainly by the corpus luteum in the ovary during the second half of the menstrual cycle, known as the luteal phase.
What Does Progesterone Do?
Some key functions of progesterone include:
- Preparing the uterine lining for possible implantation of a fertilized egg
- Supporting the early stages of pregnancy if fertilization occurs
- Balancing the effects of estrogen in the body
- Playing a role in the menstrual cycle and ovulation
During the luteal phase, progesterone levels rise significantly. This causes the uterine lining to thicken and be filled with blood vessels, so that it is ready to receive and nourish a fertilized egg.
If pregnancy does not occur, progesterone levels will drop, which triggers
menstruation. The drop in progesterone signals the uterus to shed its lining.
Progesterone Levels During Pregnancy
If pregnancy occurs, the corpus luteum continues producing progesterone during the first trimester. After the first trimester, the
placenta takes over progesterone production.
Progesterone levels continue to rise during pregnancy, peaking in the third trimester. The high levels of progesterone help maintain the thick uterine lining to support the growing fetus. Progesterone also suppresses muscle contractions in the uterus, preventing early childbirth.
