Abortion may affect the fetal arrest, to avoid unnecessary abortion. Abortion is a surgical procedure to terminate early pregnancy within 10 weeks, and it should be operated by a professional physician. Due to the presence of uterine operations, a high number of abortions will increase the risk of uterine infections, which may affect the normal implantation of the embryo, or the risk of fetal ejection due to endometrial abnormality and other reasons after the embryo is implanted. Multiple abortions are more damaging to a woman’s body, and will also increase the occurrence of uterine adhesions, chronic pelvic inflammatory disease, menstrual disorders and secondary infertility and other complications. For women who do not have the desire to have children, they should choose safe and effective contraceptive methods under the guidance of a doctor, such as condoms, placing intrauterine devices, and taking contraceptive pills, in order to avoid unwanted pregnancies.
