What is Progesterone?

Progesterone is a key hormone that plays many important roles in the female reproductive system and pregnancy.

What Exactly is Progesterone?

• Progesterone is a steroid hormone produced mainly by the corpus luteum in the ovary after ovulation. It is also produced by the placenta during pregnancy.
• It helps prepare the uterine lining (endometrium) for implantation of a fertilized egg and maintains pregnancy. Thus, progesterone is absolutely vital for fertility and ensuring a healthy pregnancy.
• Progesterone also interacts with estrogen during the menstrual cycle. There is a careful balance between estrogen and progesterone that regulates the menstrual cycle phases.

Key Functions of Progesterone

• Thickening the endometrium - Progesterone stimulates growth of blood vessels and glands in the endometrium to prepare for pregnancy. This provides essential support for the early embryo.
• Preventing further ovulation - After ovulation, progesterone prevents the release of further eggs. It inhibits the hormones that stimulate ovulation.
• Maintenance of early pregnancy - If pregnancy occurs, the corpus luteum continues secreting progesterone. Later, the placenta takes over. Progesterone relaxes uterus muscles to discourage contractions.
• Development of breast tissue - Progesterone stimulates the growth of the lobules and alveoli of the breast during pregnancy, preparing for lactation and breastfeeding.

So, in summary, progesterone has wide-ranging impacts on the female reproductive system, from the menstrual cycle to pregnancy. It interacts closely with estrogen and helps create the optimal environment in the body to achieve and maintain pregnancy.
