Do small uterine fibroids affect pregnancy?

Will small uterine fibroids affect conception? Every woman has a wish to be a mother, but for some women, the appearance of some diseases may prevent some people from becoming mothers. Among them, uterine fibroids is a gynecological disease that often occurs in female friends. Many women are very afraid and worried about this disease, and they are worried about whether it will affect their conception. So, will uterine fibroids affect conception?

Do small uterine fibroids affect pregnancy?

Whether fibroids affect conception depends on the location, size, and number of the fibroids. For example, cervical fibroids can affect the entry of sperm into the uterine cavity, submucosal fibroids can easily cause endometrial infection and be detrimental to the implantation of fertilized eggs, and giant multiple uterine fibroids can easily squeeze the interstitial part of the fallopian tube and hinder the passage of sperm. In addition, uterine fibroids can cause congestion and dilation of the muscle wall or endometrial veins, leading to changes in the intrauterine environment that are not conducive to implantation of the fertilized egg; or insufficient blood supply to the developing embryo, leading to miscarriage. The incidence of miscarriage is 2 to 3 times that of pregnant women without fibroids, and is often incomplete.

Large intramyometrial or submucosal fibroids can hinder fetal movement in the uterus, causing malposition of the fetus, such as transverse presentation, breech presentation, etc., and increase the number of cesarean sections. During the delivery process, fibroids may affect the normal contraction of the uterus and prolong the delivery process; fibroids embedded in the pelvic cavity may block the birth canal and cause dystocia. Fibroids can also affect postpartum uterine contraction, causing postpartum hemorrhage or poor uterine involution. If the uterine cavity drainage is affected or ulcers occur on the surface of the fibroids, infection is likely to occur.

Pregnancy also has a certain impact on fibroids. After pregnancy, uterine fibroid tissue becomes edematous and smooth muscle cells hypertrophy, so the fibroids often grow along with the uterus. Because the fibroids grow rapidly during pregnancy and lack blood supply, degenerative changes occur, among which red change is the most common. Patients may experience acute abdominal symptoms such as fever, headache, vomiting, local tenderness, and increased white blood cell count.

Small uterine fibroids affect conception performance;

1. Uterine fibroids growing in the cervix can compress the cervical canal, which is not conducive to the entry of sperm into the cervical opening and affects pregnancy.

2. Submucosal uterine fibroids growing in the uterine cavity affect the entry and implantation of sperm, thereby affecting pregnancy.

3. Uterine fibroids growing in the broad ligament can easily cause the fallopian tubes to stretch, twist and become blocked, affecting pregnancy.

4 Larger uterine fibroids can deform the uterine cavity, which is not conducive to the passage of sperm, implantation of fertilized eggs and fetal development.

5. Uterine fibroids growing near the uterine horns will compress the opening of the fallopian tubes, causing blockage of the fallopian tubes and thus affecting pregnancy.

Uterine fibroids are a type of hormone-dependent tumor. Estrogen is the main factor that promotes the growth of fibroids. Some scholars also believe that growth hormone (GH) is also related to the growth of fibroids. GH can cooperate with estrogen to promote mitosis and promote the growth of fibroids. It is speculated that human placental lactogen (HPL) can also cooperate with estrogen to promote mitosis. It is believed that the accelerated growth of uterine fibroids during pregnancy is related to the high hormone environment during pregnancy, and HPL may also play a role.

What are the hazards of uterine fibroids during pregnancy?

Although the chance of developing uterine fibroids during pregnancy is high, serious complications are rare.

(less than 1). Uterine fibroids will change as pregnancy progresses. Some fibroids will change position, some will increase in size, and some fibroids will cause "reddening and degeneration" due to tissue congestion and thrombosis after pregnancy, leading to abdominal pain and uterine contractions. However, clinical observations and most statistical evidence have shown that uterine fibroids do not increase the risk of premature birth.

However, it should be noted that some larger fibroids affect the rotation of the fetus, resulting in malposition of the fetus; some low-positioned fibroids block the fetal passage, increasing the chance of cesarean section. Only in very rare cases, such as when a pedicled serosal fibroid undergoes torsional necrosis, immediate surgery is required; or when a mucosal fibroid causes prenatal bleeding or placental abruption; or when a fibroid affects postpartum uterine contraction, leading to massive postpartum hemorrhage. Obstetricians and gynecologists must pay attention to these serious complications!
