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 uterus for pregnancy. Progesterone helps build up the lining of the uterus during the menstrual cycle. This provides a place for a fertilized egg to implant and grow.


• Supports pregnancy. After ovulation, the corpus luteum in the ovary ramps up progesterone production. This progesterone helps maintain the uterine lining and supports the early stages of pregnancy before the placenta forms.


• Regulates periods. Progesterone levels rise and fall during each menstrual cycle. When levels drop, this signals the body to shed the uterine lining, starting a new cycle.

Sources in the Body

During the menstrual cycle, progesterone is produced mainly by the corpus luteum in the ovary. The corpus luteum forms after ovulation from the leftover follicle. If pregnancy occurs, the placenta eventually takes over progesterone production.

Progesterone production is stimulated by luteinizing hormone (LH) from the pituitary gland. This hormone surges around ovulation, triggering the corpus luteum to produce more progesterone.

Role in Fertility

Having adequate progesterone is key for fertility. Many couples struggling to conceive have low progesterone levels, often due to not ovulating normally. Getting progesterone levels tested can identify issues.

If levels are low, progesterone medications or supplements may be used to support both natural and assisted pregnancies. This helps thicken the uterine lining for embryo implantation.
