A woman who has had a tubal ligation for 20 days can have intercourse with or without a condom. Sperm and egg are united in the lumen of the fallopian tube and will transport the fertilized egg through the tube to the uterus. A tubal ligation is performed to block the sperm and egg from meeting, thus achieving sterilization. It is a permanent form of contraception and is relatively safe. After tubal ligation, you should not have sex for two weeks. After two weeks, if there is no discomfort, you can have sex. Now that it has been 20 days since the surgery, of course you can have sex. After tubal ligation, there is usually no need to take other contraceptive measures, so you can also have sex without using condoms. However, in order to prevent the occurrence of some sexually transmitted diseases, condoms can also be used.
