In clinical practice, there are many types of abortion drugs. Their primary purpose is to kill the embryo or fetus and then promote uterine contractions to expel the fetus from the uterus. From the perspective of the drugs alone, abortion drugs do not cause infertility because the drugs are metabolized quickly. However, if abortions are performed repeatedly multiple times, this may potentially lead to infertility. The cause of infertility in such cases is not related to the drugs but due to the repeated abortions, which could affect the woman's endometrium, cervix, and fallopian tubes. Therefore, it is advisable for women to minimize unnecessary abortions to reduce the risk of infertility caused by the abortions.
