What is Progesterone? Your Ultimate Guide

Progesterone is a crucial steroid hormone predominantly produced in a woman's ovaries. It's also produced in smaller amounts by the adrenal glands and, during pregnancy, the placenta. Think of it as a key player in a complex hormonal orchestra, conducting a symphony of bodily functions.

What does progesterone do? Its primary role is preparing the body for potential pregnancy and supporting it once conception occurs. However, its influence extends far beyond that.

• The Menstrual Cycle: After ovulation, progesterone thickens the uterine lining (endometrium), creating a nutrient-rich environment for a fertilized egg to implant. If fertilization doesn't occur, progesterone levels drop, leading to the shedding of the uterine lining – your period.
• Pregnancy: Once pregnancy is established, progesterone is vital. It suppresses the mother's immune system to prevent the body from rejecting the fetus. It also helps reduce uterine contractions to prevent premature labor. Many women take supplemental progesterone during early pregnancy to reduce the risk of miscarriage.
• Other Roles: Progesterone also impacts various bodily processes, including:
  • Mood regulation: Fluctuations in progesterone levels are linked to mood swings, especially around menstruation.
  • Sleep: Progesterone plays a role in sleep.
  • Bone health: Progesterone aids in calcium absorption, essential for strong bones.
  • Cholesterol metabolism: It influences cholesterol levels, potentially affecting cardiovascular health.

What happens when progesterone is low? Low progesterone can manifest in various ways depending on the individual and underlying cause. Some common symptoms include:

• Irregular or absent periods (amenorrhea)
• Infertility
• Miscarriage
• Premenstrual syndrome (PMS) symptoms such as bloating, breast tenderness, and mood swings
• Low libido

What happens when progesterone is high? Conversely, high levels could indicate conditions like polycystic ovary syndrome (PCOS) or ovarian tumors. Symptoms may include irregular periods, acne, weight gain, and hair growth issues. Some of these effects might also be experienced from birth control pills, which regulate progesterone levels.

How is progesterone measured? Blood tests are commonly used to measure progesterone levels. Doctors often order these tests to investigate infertility, menstrual irregularities, or pregnancy-related concerns.
