Progesterone is an important hormone that plays a vital role in the female menstrual cycle and pregnancy. It is a steroid hormone produced mainly by the corpus luteum in the ovary during the second half of the menstrual cycle.
Some key functions of progesterone include:
Progesterone levels vary throughout the menstrual cycle. After ovulation occurs around day 14, progesterone levels will rise and help thicken and prepare the uterine lining for pregnancy.
If fertilization does not occur, progesterone levels will drop sharply, and menstruation will start. If fertilization does occur, the embryo produces hCG to signal the corpus luteum to continue secreting progesterone to support pregnancy.
Progesterone is essential for maintaining a healthy pregnancy. It acts on the uterine muscles to prevent early contractions and relaxes blood vessels to increase blood flow. This provides oxygen and nutrients to the developing baby.
Problems with progesterone production in early pregnancy may result in an increased risk of miscarriage. Some women who have experienced repeat pregnancy loss may benefit from progesterone supplements.
There are cases where progesterone medications may be prescribed:
Progesterone blood tests can help diagnose issues like infertility, ovarian problems, early menopause, and more. Levels that are too high or too low can indicate hormonal imbalances.
