Normally, after orgasm, there will be more secretion of cervical discharge, vaginal discharge and vestibular fluid, so it will lead to an increase in discharge. However, this secretion does not change in color or in nature. So if there is abnormal leucorrhea after orgasm, the abnormality is a change in color, yellow or red, or like slop. Changes in the nature of the leucorrhea, such as a large amount of foam or tofu-like leucorrhea, are abnormal. The majority of these cases are due to vaginal inflammation caused by bacterial infections. It is recommended that routine laboratory tests of the leucorrhoea be performed, and that the appropriate medication be administered according to the pathogenic bacteria. In addition, it is recommended to pay attention to the hygiene of sexual life.
