Progesterone is a vital hormone that plays a key role in the female reproductive system and pregnancy. As one of the main female sex hormones along with estrogen, progesterone has many important functions:
- Regulating the menstrual cycle and ovulation: Progesterone helps prepare the uterus for pregnancy each month. It thickens the uterine lining to support a fertilized egg. If pregnancy does not occur, progesterone levels drop, leading to menstruation.
- Supporting pregnancy: In pregnancy, the corpus luteum produces progesterone to maintain the uterine lining for the developing embryo. Progesterone helps implant the fertilized egg and promotes blood flow to the uterus. Later in pregnancy, the placenta produces progesterone.
- Preventing preterm birth: Progesterone helps the cervix stay closed and keeps the uterus relaxed. Taking progesterone supplements in the second and third trimesters can reduce the risk of preterm labor.
Now, you may wonder: _when are progesterone levels highest?_ Here's a quick rundown:
- Progesterone levels are lowest during menstruation and start to rise after the period ends.
- Levels peak around ovulation, about a week before the next period. This triggers the luteinizing hormone (LH) surge that releases the egg.
- If fertilization occurs, progesterone remains elevated to support the pregnancy. Otherwise, it drops sharply leading up to the next menstrual cycle.
Some key facts about progesterone:
- Progesterone is produced mainly by the ovaries and placenta. The adrenal glands and fat tissues may also produce small amounts.
- It can be taken as a medication, often in the form of pills, creams, gels, or vaginal suppositories.
- Progesterone supplements may be prescribed for women with irregular periods, infertility, or recurrent miscarriages.
