Why Is The Corpus Luteum Maintained During Pregnancy?

When a woman is pregnant, there are many parts and components of her body that are essential for her and play a great role in the result of her pregnancy. This means that certain components of a woman’s body are more important during pregnancy and play a greater role in pregnancy than others. That is because these specific parts or components have certain jobs that are associated to pregnancy and if they do not function properly, a woman might lose her child. One of these greatly essential parts is the corpus luteum.

The corpus luteum is a part of a womans body and is really essential during pregnancy. The corpus luteum shrinks and enlarges. It enlarges when its time for ovulation and it starts secreting progesterone, which is a hormone and it plays a large role in getting the uterine wall ready for the fertilized egg. If the egg is not fertilized however, the corpus luteum will shrink and progesterone levels will start falling. This will consequently lead to the shedding of the uterine wall. The corpus luteum is important during pregnancy because it is the part that secrets progesterone, without which a fetus cannot form within a woman. The corpus luteum needs to be maintained during pregnancy. How and why is the corpus luteum maintained during pregnancy?

How- There is a hormone which is known as the hCG (human chorionic gonadotropin) and that is how the corpus luteum is maintained during the first 3-4 months of pregnancy, after which the placenta takes over the job of secreting progesterone. Progesterone is essential during pregnancy because it avoids the menstrual cycle and keeps the uterine wall strong. hCG is produced by the syncytiotrophoblast cells which are present in the developing embryo and that are what maintains the corpus luteum so it can produce the required amount of progesterone.

Why- Progesterone is one of the most essential hormones that are required by the female body during pregnancy. The corpus luteum does its job and then starts to shrink back and the progesterone levels decrease which cause the uterine wall to shed. This cannot and should not happen during pregnancy and that is why the female body utilizes hCG to maintain the corpus luteum and keep it in shape. This will ensure that the optimum amount of progesterone is being produced. After 3-4 months of pregnancy, the job of secreting progesterone is given over to the placenta.
