Why do women bleed after sex?

Many women have a lot of physical problems, especially some women will experience bleeding after sexual intercourse but don’t know what’s going on. Generally speaking, bleeding after sexual intercourse may be caused by some gynecological diseases, such as pelvic inflammatory disease.

1. Cervical polyps

Chronic inflammation may cause cervical polyps due to long-term stimulation of the cervix. Single or multiple small pedunculated granulation tissues grow at the cervical opening, looking like bean buds, and the larger ones are as big as a finger. Polyps are fragile and tender, and will bleed if touched, so bleeding may occur after sexual intercourse. This bleeding is usually bright red.

2. Cervical cancer

Bleeding after sexual intercourse is the earliest symptom. Because there are more small blood vessels and the tissues are more fragile in the cancer lesions, the capillaries will rupture and bleed due to damage after each sexual intercourse. If the cancer grows further, it will bleed more easily.

3. Endometriosis

Some endometriosis grows on the cervix and appears as blue-purple nodules. If this blue-purple ectopic nodule is touched during sexual intercourse, it will cause bleeding. The amount of bleeding is generally small and dark red, and abdominal pain often occurs after intercourse.

4. Pelvic inflammatory disease

Pelvic inflammation can cause pelvic congestion. If the endometrium is congested and edematous, sex may cause the congested endometrium to release hormones, but this opportunity is rare.

5. Cervicitis (erosion)

90% of married women suffer from cervicitis. Cervicitis is divided into three types: mild, moderate and severe according to the degree of cervical erosion. For patients with moderate or severe cervical erosion, the rubbing of the cervix by the glans of the male's penis during sexual intercourse may cause injury and bleeding. Because the amount of bleeding is small, it does not flow out immediately but accumulates in the vagina, and the color of the blood changes from fresh to old. Therefore, when the blood flows out the next day, it is dark red.
