Uterine fibroids are the most common benign tumors in women, commonly found in women of childbearing age, and according to statistics, about 20% of women over 30 years old have fibroids. It is estimated that about 20% of women over 30 years of age have fibroids. Whether a patient with fibroids can get pregnant is mainly related to the size and location of the fibroids. Most fibroids do not affect pregnancy, but some fibroids may affect conception or cause miscarriage and abnormal delivery. It is recommended that patients with fibroids undergo a preconception examination when preparing for pregnancy, and that any fibroids that require treatment be treated early. The uterine wall is divided into plasma layer, myometrium and mucosa layer from outside to inside, and fibroids are divided into interstitial fibroids, subplasma fibroids and submucosal fibroids according to the relationship between fibroids and the muscle wall. In general, fibroids that do not project into the uterine cavity, such as subplasma fibroids and smaller interstitial fibroids, can cause pregnancy because they have less impact on the endometrium and the morphology of the uterine cavity. Submucosal fibroids that are convex to the uterine cavity and closely related to the endometrium can interfere with the fertilization of the egg and lead to early miscarriage; interstitial fibroids that are located in the myometrium can cause miscarriage due to enlargement and distortion of the uterine cavity or insufficient blood supply to the endometrium. Subplasmalemmal fibroids that protrude from the surface of the uterus may cause acute abdominal pain if they twist and rupture, and require surgery. Low-growing fibroids can prevent the head of the fetus from descending, increasing the risk of abnormal fetal position, low placenta, placenta previa, obstructed labor and delivery during late pregnancy and delivery; large fibroids can make it difficult to expel the placenta after delivery or cause postpartum hemorrhage due to uterine contractions, which can be life-threatening. Pregnancy is not recommended for patients with these types of fibroids. Moreover, during pregnancy, fibroids are prone to a special type of necrosis degeneration, and in severe cases, the mother may experience severe abdominal pain accompanied by nausea, vomiting, and fever, but most of them can be relieved by conservative treatment.
