Progesterone

What is progesterone?

Progesterone is a steroid hormone that plays a vital role in the female menstrual cycle and pregnancy. Here's an overview:

Key Functions

• Prepares the uterine lining for implantation of a fertilized egg


• Maintains pregnancy by supporting the developing fetus


• Contributes to normal menstruation if no pregnancy occurs

Natural Production

Progesterone is mainly produced by the corpus luteum in the ovaries during the second half of the monthly cycle, known as the luteal phase. Levels peak around 7 days after ovulation.

If an egg is fertilized, the corpus luteum continues producing progesterone to maintain the uterine lining for early pregnancy. Later, the placenta takes over progesterone production.

Supplementation

Some women take progesterone supplements for conditions like:

• Infertility


• Repeated miscarriages


• Irregular periods


• Perimenopause symptoms

Progesterone supplements can be delivered as pills, creams, vaginal gels, and intrauterine devices. Brands include Prometrium, Crinone, and Prochieve. Speak to a doctor about whether supplementation may help your condition.
