Can abortion cause infertility?

Artificial abortion uses vacuum suction to suck out the embryonic tissue and terminate the pregnancy. Although it is a common operation, it can cause complications or sequelae after the operation, such as endometriosis, irregular menstruation, and even amenorrhea. Therefore, some women experience abnormal menstruation or even amenorrhea after artificial abortion, which leads to infertility. According to statistics, infertility caused by artificial abortion accounts for the third place among all secondary infertility (referring to pregnancy that has occurred, but has not become pregnant for 2 years without contraception).

Infertility is not directly related to artificial abortion. Fertility will be restored soon after artificial abortion and will not directly cause infertility. The main reasons for infertility after artificial abortion are inflammation of the fallopian tubes after surgery, or excessive damage to the cervical canal and endometrium due to curettage, causing cervical adhesion obstruction or uterine cavity adhesion contraction, so that sperm cannot pass through the cervical canal smoothly into the uterine cavity, or endometritis and other factors hinder the implantation of fertilized eggs. Preventing the occurrence of inflammation and (or) avoiding excessive scraping of the endometrium can reduce the incidence of infertility after artificial abortion.
