What is progesterone?
Progesterone is a key hormone that plays an important role in the menstrual cycle and pregnancy. Some key facts about progesterone:
- Progesterone is a steroid hormone produced mainly by the ovaries in women and the adrenal glands and testes in men.
- It helps prepare the body for pregnancy each month by building up the lining of the uterus (womb).
- It helps maintain pregnancy by preserving the uterine lining needed for implantation of a fertilized egg.
- It has other functions like regulating ovulation and menstruation in women and sperm production in men.
Progesterone levels vary throughout the menstrual cycle:
- Levels are low in the follicular phase (first half of cycle).
- They rise after ovulation around day 14 of a 28-day cycle.
- High levels help maintain a pregnancy if fertilization occurs.
- If no pregnancy ensues, progesterone levels drop leading to menstruation.
Some key things that affect progesterone levels include:
- Age - levels decline naturally as women approach menopause.
- Birth control pills - contain progestins that mimic progesterone.
- Pregnancy - causes a sustained rise in progesterone from the corpus luteum and placenta.
- Menstrual cycle irregularities like PCOS can disrupt normal progesterone patterns.
Progesterone testing can be helpful for:
- Evaluating infertility issues in both men and women.
- Assessing risks of miscarriage or ectopic pregnancy.
- Monitoring hormone replacement therapy.
If progesterone levels are found to be low, progesterone supplements may be used for:
- Luteal phase defect.
- Hormone replacement therapy during menopause.
- Preventing preterm birth in high-risk pregnancies.
- Helping induce menstrual periods in amenorrhea.
