Bleeding in women after sex needs to be considered for several reasons: 1) bleeding caused by cervical inflammation, the penis touches the cervix after intercourse causing inflammation and bleeding on the surface of the cervix; 2) bleeding caused by cervical lesions needs to be ruled out, some cervical lesions are seen on the surface of the blood vessels and bleeding is caused by touching the blood vessels after intercourse. In this case, TCT and HPV examination of the cervix is needed. If the TCT and HPV examination are normal, the cervical bleeding can be ruled out; if the TCT and HPV examination are abnormal, further colposcopy is needed to rule out cervical lesions. If there is no lesion, rest is sufficient. If there is lesion, further examination and treatment are needed.
