What is the cause of poor ovarian follicles?

There are many reasons for poor follicles, some of which are closely related to some reproductive health problems of women. For example, premature ovarian failure in women will cause a decline in follicle quality. In addition, the indiscriminate use of ovulation-stimulating drugs or polycystic ovary syndrome will affect the quality of follicles.

1. Follicular development Follicular dysplasia refers to the situation in which the follicles in the late follicular stage cannot reach the size of mature follicles, have poor function, and secrete insufficient estrogen. Clinical examination results show that the cervical score cannot reach the expected high value (>10 points).

2. The size of the follicle considered mature is determined by the individual's physical condition, and each person's situation is different. Generally speaking, the normal size of a mature follicle is 18-25mm.

3. Every month, women will only release one mature egg, and this mature egg is generally considered a mature egg when it is larger than 20mm. However, there are individual differences. Some people will release the egg when the follicle grows to 15mm, while others will release the egg when it grows to 25mm. To determine the specific individual situation, you can do a periodic B-ultrasound examination. Usually mature follicles will be released within one to two days, and the released follicles can generally survive for 2 days.

4. Causes of poor follicular development

There are many causes of immature follicle development, the most common ones include polycystic ovary, abnormal estrogen and progesterone levels, and low follicle-stimulating hormone levels.

1. Premature ovarian failure: Poor follicle development in some women is caused by premature ovarian failure. The patient has normal menstruation in the early stage and even has a history of childbearing, but then the menstruation becomes infrequent until complete amenorrhea. The follicles in the ovaries of such patients have been exhausted, and it is impossible to use ovulation-stimulating drugs to make the follicles develop, or although there are primordial follicles, they do not respond to gonadotropins.

2. Polycystic ovary syndrome: Polycystic ovary is one of the reasons for poor follicle development. Polycystic ovary syndrome is the most common reason why women do not ovulate. The characteristics of its ovaries are that the ovaries are enlarged in size and have multiple small follicles, but they cannot develop to maturity. Therefore, drugs are needed to promote follicle development.

3. Ovulation disorders caused by abnormal function of the thyroid and adrenal cortex.
