There are many bad effects of abortion, and the effects on women are mainly reflected in the following aspects: First, excessive damage to the endometrium, infection of the uterine cavity, perforation of the uterus, and damage to the pelvic organs may occur in the course of the operation. Secondly, after the abortion surgery, there may be endometrial adhesion, low menstrual flow or even amenorrhea due to the damage of the endometrium. Thirdly, if there is endometrial damage or amenorrhea, it will affect the patient’s ability to conceive, resulting in secondary infertility or habitual abortion. Fourthly, if there is endometrial damage, the possibility of placenta implantation or hemorrhage will be very high if the patient gets pregnant again. Fifth, the endometrial lining is damaged during abortion, which may easily lead to the invasion of the mesenchyme and glands of the endometrium into the myometrium, resulting in the occurrence of endometriosis.
