What causes vaginal bleeding after sex?

Generally speaking, normal and coordinated sexual life will not cause vaginal bleeding in women. Vaginal bleeding after intercourse often indicates the presence of some pathological condition. Vaginal bleeding generally refers to abnormal vaginal bleeding. Abnormal vaginal bleeding is one of the most common symptoms of female reproductive diseases. Why does women bleed from the vagina after having sex? There are many reasons for female bleeding during sexual intercourse, which can be roughly divided into two categories: improper sexual intercourse and local organic lesions of the female reproductive system, with the latter being more common.

1. 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.

2. 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.

3. 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.

4. 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.

5. Pelvic inflammatory disease. Pelvic inflammation can cause pelvic congestion. If the endometrium is congested and edematous, the congested endometrium may bleed after sex, but this chance is rare.

6. Sexual intercourse injury. A common site of sexual intercourse injury is the vaginal foramina, which can sometimes cause a foramina several centimeters long. In severe cases, it can reach the peritoneum or penetrate the peritoneum into the abdominal cavity. Some people mistakenly believe that pressing some gauze on the vulva or using some menstrual paper will stop the bleeding, but in fact this does not help. Therefore, if this happens, you need to go to the hospital for examination and treatment as soon as possible. The gynecologist will take appropriate treatment measures according to the specific circumstances of the injury, such as inserting gauze into the vagina for compression or using intestinal sutures to stop bleeding.

What causes vaginal bleeding after sex? If bleeding during sexual intercourse is caused by improper sexual intercourse, the couple should learn about sexual knowledge together and adopt appropriate sexual intercourse methods and positions. During sexual intercourse, the movements should be gentle, avoid being rough, and avoid inserting before the vagina is fully moistened. If the cause of rupture of the hymen during the first sexual intercourse is ruled out, it is basically a local organic disease of the reproductive system. Do not be careless if vaginal bleeding occurs after intercourse. Be sure to go to the hospital for examination in time to avoid delaying treatment.
