Estrogen determines follicle quality

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 levels of estrogen and progesterone are determined by the development of follicles, rather than estrogen and progesterone determining the development of follicles. Therefore, do not confuse cause and effect.

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.

The high and low levels of progesterone reflect the function of the corpus luteum after ovulation. If the corpus luteum function is poor, the menstrual cycle may be shortened. If the corpus luteum is incompletely atrophied, it will cause prolonged menstruation. If after ovulation, sexual intercourse forms a fertilized egg, the corpus luteum is called the corpus luteum of pregnancy. Before the placenta is formed at 8 weeks of pregnancy, it performs the function of secreting estrogen and progesterone to maintain pregnancy.

The ovaries can be said to be an important organ in the female reproductive period. Like the male testicles, there is one on each side of the body. Between two menstrual periods, the ovaries will discharge mature eggs. If you have sex during this period, there is a great possibility that they will combine with sperm, develop into a fertilized egg, and implant in the uterine cavity to develop into an embryo, followed by a successful pregnancy. If there is no sperm to combine with it, it will be expelled from the body.

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.
