Uterine fibroids are the most common benign tumors in women, mostly occurring between the ages of 30 and 50, and according to statistics, the incidence rate is over 20%, which means that more than one in five women of childbearing age have fibroids. The actual incidence is even higher than this, and a considerable number of women are found to have uterine fibroids before they have children. So why is it important to remove large fibroids in infertile patients? Because fibroids often increase in size with the enlargement of the uterus during pregnancy. Sometimes fibroids increase faster during pregnancy and the blood supply is insufficient, which makes them prone to fibroid degeneration, with red degeneration being the most common. Red degeneration is manifested by fever, abdominal pain, vomiting, local pressure pain and elevated white blood cells. Uterine fibroids have a series of adverse effects on pregnancy, delivery and early puerperium, such as high rate of miscarriage, fetal malposition, high rate of cesarean section and postpartum bleeding. It is generally believed that patients with uterine fibroids with a maximum diameter of more than 4-5 cm should undergo myomectomy before pregnancy! If you have fibroids and the amount of fibroids is large, as long as no other cause of infertility is detected, you can excavate regardless of how many tumors there are and regardless of how large the tumors are, and you should use contraception for six months to a year after surgery.
