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


• Involved in breast development during puberty

Progesterone is produced mainly by the corpus luteum in the ovary after ovulation. The corpus luteum forms from the follicle that released the egg.

If pregnancy occurs, progesterone levels stay elevated to maintain the uterine lining. If no pregnancy happens, progesterone levels drop, which signals the next menstrual period.

Role in Menstrual Cycle

• Follicular phase: Progesterone levels are low while the follicle containing the maturing egg develops


• Ovulation: Estrogen peaks, causing a spike in luteinizing hormone that triggers ovulation


• Luteal phase: The corpus luteum produces more progesterone to thicken the uterine lining in preparation for a fertilized egg


• If no pregnancy, corpus luteum breaks down, progesterone drops, and menstruation occurs

Thus, progesterone works together with estrogen to control the menstrual cycle phases.
