What is the reason for the ovaries not releasing eggs?

For normal female friends, ovulation occurs once a month, usually around two weeks before menstruation. However, some female friends find that they do not ovulate. Ovarian anovulation is a common endocrine disease, which often manifests as menstrual disorders and is likely to lead to unsuccessful conception. So do female friends know why their ovaries do not ovulate? Now let me give you a detailed explanation.

1. Turner syndrome and simple gonadal dysgenesis chromosomal abnormality diseases both have primary amenorrhea as the main clinical manifestation, with increased gonadotropin and decreased estrogen. Pregnancy can be achieved through in vitro fertilization and embryo transfer using eggs donated by others.

2. Premature ovarian failure and ovarian antagonism syndrome: Hypergonadotropic amenorrhea caused by ovarian failure that occurs before the age of 40 is called premature ovarian failure, which accounts for about 20% to 28% of primary amenorrhea and 4% to 20% of secondary amenorrhea. Women with primary amenorrhea or secondary amenorrhea before the age of 30 have elevated levels of endogenous gonadotropin and normal follicles in their ovaries, but are low-responsive to high-dose exogenous gonadotropin stimulation. This is called ovarian insensitivity syndrome or ovarian antagonism syndrome. The causes of both diseases are still unclear, and both present with amenorrhea and anovulation.

3. Polycystic ovary syndrome: often manifested as amenorrhea or infrequent menstruation, long-term anovulation, excessive androgen, and no cyclical fluctuations in estrogen. It is currently a major cause of anovulatory infertility.

4. Unruptured luteinized syndrome: In a normal menstrual cycle or a drug-induced ovulation cycle, an ovarian follicle develops into a dominant follicle, but the follicle does not disappear or maintains growth 48 hours after the LH peak during ovulation, and exists for several days. The granulosa cells have become luteinized, but the follicle has not ruptured. The basal body temperature (BBT), cervical viscosity and endometrial changes in LUFS are similar to normal ovulation, giving the illusion of ovulation. It is one of the causes of infertility and one of the reasons why the pregnancy rate of clomiphene-induced ovulation is low.

I believe everyone understands the reason why the ovaries do not ovulate. Usually, the reason why ovulation does not occur is because of abnormalities in the body, and the body can recover by carefully conditioning the body. However, if ovarian failure to ovulate becomes the norm, you should go to the hospital for a detailed examination and receive timely treatment. Finally, the editor wishes all women good health.
