Do not have sex for 2-3 days before your gynecological examination. This is because during gynecological examinations, cervical smears, cervical cancer screening and white belt tests are usually required. If you have sex before the examination, the sperm will affect the vaginal environment, resulting in unsatisfactory specimens, which will also affect the results of the examination, which is ineffective. In addition to intercourse, vaginal medication should not be applied within 2-3 days before the gynecological examination. Local vaginal plugs can also affect the vaginal environment and lead to errors in the examination results. In addition, it is usually necessary to hold urine before the gynecological examination because ultrasound examination is needed.
