Hazards of uterine cysts: I. Menstrual irregularities. The presence of uterine cysts can cause excessive menstrual flow and irregular uterine bleeding in patients. II. Causing female infertility. When there are more and more uterine cysts, it will prevent the presence of sperm and pregnant eggs, and even no way to smoothly lay, thus leading to female infertility. In addition, uterine cysts can also induce infection and inflammation, which can reduce the viability of sperm, and some patients with uterine cysts have fallopian tube or ovarian inflammation and cannot get pregnant normally. Third, lead to miscarriage. If women with uterine cysts get pregnant, they are likely to miscarry in early pregnancy due to poor blood supply to the placenta. The more serious the condition, the greater the chance of miscarriage.
