Under normal circumstances, patients can only have intercourse one month after painless abortion surgery, mainly because of the following 2 reasons: first, after abortion surgery, patients will have vaginal bleeding, 7-10 days, the longest will not exceed half a month. Blood is the best petri dish for bacteria, and the patient’s cervical opening is relatively loose at this time, if the patient has intercourse at this time, it is particularly easy to cause upward infection, resulting in pelvic inflammatory diseases and fallopian tube failure and other diseases, which will have a very great impact on the patient’s health and reproduction. Secondly, the patient’s abortion surgery also has a certain damage to the ovarian function, so the patient’s estrogen and progesterone levels are relatively low after the operation, the vaginal microenvironment will also be damaged, so this time coitus is particularly easy to appear vaginal dryness and vaginal inflammatory diseases.
