After the TCT examination, you should not have intercourse even if you wear a condom. The reason is that during the TCT examination, the brush used to take the specimen is inserted into the cervical canal to take the specimen, which will lead to localized rupture of capillaries, causing bleeding, and will also lead to localized mucous membrane damage. If there is localized damage, intercourse is likely to bring in pathogenic bacteria. It is recommended to have intercourse one week after the specimen is taken, if there is no vaginal bleeding. If you are not planning to get pregnant, you can use a condom during the whole process of sexual intercourse, which will achieve a more satisfactory contraceptive effect. Therefore, even if you wear a condom, you should not have intercourse after the TCT. The purpose of wearing a condom is to avoid pregnancy, but even if a condom is worn, it may lead to pathogenic bacteria infection, so coitus is not allowed.
