About uterine fibroids?

Uterine leiomyoma is a common reproductive benign tumor disease in women. The main pathogenic mechanism is smooth muscle cell proliferation with a small amount of fibrous connective tissue. Women aged 30-50 years old are the high incidence of uterine fibroids. Uterine fibroids can grow singly or in multiple sizes. Clinical research shows that about 22% ~ 32% of patients with hysteromyoma will have infertility, among which submucosal myoma has the highest infertility rate. Therefore, not all uterine fibroids can lead to infertility. Leiomyoma of uterus can be divided into subserous leiomyoma, intramural leiomyoma, submucosal leiomyoma, cervical leiomyoma and leiomyoma of broad ligament. Generally speaking, single, small subserous and intramural hysteromyoma will not affect women's conception and pregnancy, but hysteromyoma in the following situations will cause infertility relatively:

1. Larger uterine fibroids will cause uterine cavity deformation, which will lead to sperm failure, or adversely affect the implantation of fertilized eggs and fetal development, thus causing infertility.

2. The growth position of hysteromyoma is near the uterine horn, and it is pressed at the opening of fallopian tube, causing fallopian tube obstruction, thus causing infertility.

3. The hysteromyoma growing in the broad ligament can lengthen and twist the fallopian tube that benefits from its surface, so that the lumen of the fallopian tube is squeezed, thus affecting the patency of the fallopian tube, or leading to the displacement of the ovary, widening the distance between the ovary and the fallopian tube, hindering the egg collection function of the umbrella-shaped end of the fallopian tube, and also causing infertility of patients.

4. Uterine fibroids that grow in the cervix will compress the cervical canal, thus blocking the passage or changing the orientation of the cervix, making
