What is Progesterone?

Progesterone is an important hormone that plays a vital role in the female menstrual cycle and pregnancy.

What Does Progesterone Do?

• Progesterone is secreted by the corpus luteum in the ovary after ovulation. It helps prepare the uterine lining for implantation of a fertilized egg.
• If pregnancy occurs, progesterone levels remain elevated to maintain the pregnancy by:
  • Thickening the uterine lining to support the growing fetus
  • Preventing the muscles of the uterus from contracting
  • Supporting the development of breast tissue and milk glands
• If pregnancy does not occur, progesterone levels drop, causing menstrual bleeding and shedding of the uterine lining.

Key Facts About Progesterone

• Progesterone is classified as a steroid hormone like testosterone and estrogen.
• It plays a vital role in the menstrual cycle. Levels rise after ovulation, peak during the luteal phase, and fall sharply if fertilization does not occur.
• Progesterone helps maintain pregnancy by ensuring the uterus provides an optimal environment for the developing fetus.
• Measuring progesterone levels via blood test can help monitor ovarian function and confirm ovulation.
• Progesterone supplements may be prescribed for women with irregular cycles or luteal phase defects.
• Declining progesterone signals the start of menopause as ovarian function diminishes.
