Estrogen determines follicle quality

Follicle quality is very important for women, because follicle quality affects women's fertility. Pregnancy is generally very important for everyone. Follicle quality can be caused by many reasons, so we should pay attention to these reasons. Therefore, some people have proposed that estrogen determines follicle quality. So does estrogen determine follicle quality?

The reason why clinicians look at estrogen and progesterone levels is because ovarian estrogen is determined by the developing follicles. The development of follicles is a team effort. Before ovulation, the follicle is divided into seven layers: the outer follicle membrane, the inner follicle membrane, the granulosa cells, the follicular cavity, the cumulus ovum (where the egg cell is hidden deep inside), the corona radiata, and the zona pellucida.

The egg, also known as the oocyte, is surrounded by granulosa cells and theca cells. These two types of cells are the main sources of estrogen secretion. The level of estrogen can reflect the development of follicles, but estrogen does not determine the development of follicles. For example, a child’s high test scores do not necessarily mean that the child is excellent; it is precisely because the child is excellent that he or she gets high scores.

Under normal circumstances, ovulation is regular every month, usually around 28 days. Some women will have fewer or more ovulations, but generally speaking, it is normal as long as it is within 21 to 35 days. If a woman ovulates less or very few ovulations during the ovulation period, ovulates irregularly, or even does not ovulate, these are all considered abnormal ovulation. Whether ovulation is normal affects whether normal pregnancy can occur, so if ovulation is abnormal, you should check in time to find out the cause.
