Post coital bleeding (PCB) refers to spotting or bleeding that is unrelated to menstruation that occurs during or after sexual intercourse. This is a very important symptom that needs prompt investigation and should not be ignored.

This type of abnormal bleeding is not usually heavy and is often only noticed when you are wiping yourself. Even though the amount of bleeding may be minimal it is important to have this further investigated. If you are experiencing PCB, you may also be experiencing abnormal bleeding not associated with intercourse.

Reasons for Bleeding after Sex

Cervical Ectropion

The cells that line the cervical canal are quite fragile and a cervical ectropion is a condition or an anatomical variation in which the canal of the cervix turns inside out exposing these fragile cells to the vaginal environment. These cells bleed easily when touched and if you have this variation of your cervix, you will most likely experience PCB.

Cervical Polyps

The cells that line the canal of the cervix can also generate polyps. These endocervical polyps are usually benign growths but because they have a rich blood supply, they can bleed during intercourse


Inflammation of the cervix can cause PCB. Chlamydial infection is the most common cause of acute cervicitis and is an infection that can affect your fertility.

Although cancer of the cervix is becoming less common because of regular cervical screening tests and will continue to become less common because of the HPV vaccination program, PCB can be a sign of precancerous or cancerous cells on the cervix.

When to See a Gynaecologist

If you are experiencing PCB you should always see your GP and be referred to a Gynaecologist.
