Sexual intercourse is prohibited for 1 month after tubal ligation surgery. For women who need to get pregnant again, post tubal ligation reversal surgery should be performed within 1 week after menstruation. It takes time for the tubal docking incision to heal after the operation, and the probability of pregnancy is not high during the healing period, and to prevent infection, sexual intercourse is prohibited for 1 month after the operation. After the next menstrual period is cleared, you can start your sexual life and prepare for pregnancy. Since there is still a possibility of re-adhesion of the fallopian tubes after tubal ligation and an increased risk of ectopic pregnancy, women who are able to do so may choose to undergo ultrasound-guided hysterosalpingogram to clarify the status of tubal recanalization and then prepare for pregnancy. If you have intercourse before the first month after tubal reversal, you should pay attention to prevent uterine and pelvic infections, and if you have delayed menstruation, you should take a pregnancy test and carefully exclude ectopic pregnancy.
