It is recommended that women have intercourse one month after the reversal surgery. The reversal surgery is mainly performed after the tubal ligation and the tubes are open for pregnancy preparation. It is recommended that women should have intercourse during ovulation after one month of recovery to avoid infection and take anti-infection medication. Folic acid can be taken under the guidance of a doctor during pregnancy preparation to prevent neural tube abnormalities in the fetus. Regular checkups should be performed after the revision surgery because there are cases of re-adhesion to avoid ectopic pregnancy. When there is a delay in menstruation during intercourse one month after the revision surgery, go to the hospital immediately for an ultrasound examination to see if the pregnancy is intrauterine.
