Great thanks! :) :)

It didn't work

If the triplets came from one coprus luteum, they would be identical rather than fraternal. Identical siblings come from one fertilized egg that splits, one time or more.

Fraternal siblings come from coincidental, separate fertilizations, meaning that more than one egg was ovulated, which requires more than one coprus luteum in the ovaries.

I hope this helps a little more. Thanks for asking.

In a woman who has given birth to triplets, it is expected that only one corpus luteum would be found in her ovaries. To understand why, let me explain the concept of corpus luteum and its relationship with pregnancy.

The corpus luteum is a temporary structure that forms in the ovary after the release of an egg during ovulation. It plays a crucial role in preparing the uterus for pregnancy. If fertilization occurs, the corpus luteum secretes hormones such as progesterone that help maintain the uterine lining and support the early stages of pregnancy. However, if fertilization does not occur, the corpus luteum degenerates, hormone production decreases, and menstruation follows.

Now, when a woman becomes pregnant, typically only one egg is fertilized, leading to a single embryo. However, in some cases, multiple eggs can be fertilized simultaneously, resulting in multiple embryos and a multiple pregnancy, such as triplets. In this situation, all embryos implant and develop in the uterus, but only one corpus luteum is formed in the ovary.

This happens because even if multiple eggs are fertilized, only one dominant follicle reaches full maturity and ovulates. The other follicles that contain the remaining eggs do not fully develop or fail to release an egg. Therefore, only one corpus luteum is formed, regardless of the number of embryos present.

In summary, a woman who has given birth to triplets would have only one corpus luteum in her ovaries because only one egg reached full maturity, ovulated, and became fertilized. The other eggs did not reach maturity, hence no corpus luteum formation.
