If only one abortion has been performed, the chance of infertility is still very low, usually only about 1%. One abortion alone, although it also has an impact on the endometrium, has less impact as long as you pay attention to rest and regular review after the surgery and your menstruation returns to normal. However, some patients have abortions in irregular hospitals, where the sterilization is not strict and post-operative infections occur, leading to inflammation of the uterine lining and fallopian tubes, which significantly increases the probability of infertility in these patients. Therefore, you must go to a regular hospital to have an abortion and pay attention to the recovery of the endometrium after the surgery, and any abnormalities must be treated in time.
