Progesterone

Progesterone is an important hormone that plays a vital role in the female menstrual cycle and pregnancy. Let's break it down:

What Exactly is Progesterone?

Progesterone is a steroid hormone produced mainly by the corpus luteum in the ovary during the second half of the menstrual cycle. After ovulation, the corpus luteum releases progesterone to thicken and prepare the uterine lining for potential implantation of a fertilized egg.

Fun fact: The name "progesterone" comes from "pro-gestational steroid hormone", meaning it supports pregnancy.

What Does Progesterone Do?

Progesterone has several key functions:

• Thickens the endometrium (uterine lining) to prepare for implantation of a fertilized egg


• Maintains pregnancy by promoting uterine growth and preventing contractions


• Stimulates breast tissue growth in preparation for lactation and breastfeeding

Basically, progesterone makes pregnancy possible! Without adequate progesterone, a fertilized egg would have trouble implanting and the pregnancy likely wouldn't be viable.

Progesterone Across the Menstrual Cycle

• In the follicular phase (first half), progesterone levels are low


• In the luteal phase (second half), the corpus luteum pumps out progesterone, peaking about 7 days after ovulation


• If no pregnancy occurs, progesterone levels drop, triggering menstruation


• If pregnancy occurs, the placenta keeps producing progesterone to maintain the pregnancy

Progesterone Deficiency

Low progesterone can cause issues like:

• Irregular periods


• Difficulty getting pregnant


• Higher miscarriage risk


• Perimenopause symptoms
