Uterine fibroids (Hysteromyoma) Uterine leiomyoma, also known as uterine leiomyoma, is the most common benign tumor of the female genitalia. Most of them are asymptomatic, and a few show vaginal bleeding, abdominal contact with the tumor, and compression symptoms. For example, pedicle torsion or other conditions can cause pain, which is common in multiple uterine fibroids. Many female friends pay more attention to this issue after suffering from uterine fibroids, worrying that it will affect women's pregnancy. The following author will introduce in detail whether uterine fibroids affect pregnancy?

Uterine fibroids with a diameter of less than 2 cm are subserosal fibroids, which have little effect on pregnancy and can be conceived. If a woman has uterine fibroids before pregnancy, with a diameter greater than 3 cm and still growing during pregnancy, it can lead to miscarriage, premature birth, etc., and requires prompt treatment. The reasons why uterine fibroids usually affect pregnancy are as follows:

1. Large intramural fibroids cause deformation of the uterine cavity, affecting the implantation of the fertilized egg and fetal development.

Fibroids grow under the mucosa of the uterine cavity, just like foreign bodies in the uterine cavity, mechanically hindering the implantation of the fertilized egg.

3. Fibroids growing in the broad ligament and uterine horn will, to a certain extent, compress the fallopian tube and cause it to twist, hindering the movement of the fertilized egg and the function of the fallopian tube umbrella, leading to infertility.

4. Cervical fibroids can compress the cervical canal, hinder the smooth movement of sperm, or change the position of the cervical canal, causing the neck to deviate from the posterior semen pool, which is not conducive to the rise of sperm.
