It is recommended to keep the vulva clean after dilatation to avoid pathogenic bacterial infection, and not to have sex for half a month after dilatation, which can also prevent the occurrence of adhesions.

It is recommended to pay attention to sexual life and menstrual hygiene in daily life to reduce the occurrence of cervical inflammation.
