What causes vaginal bleeding after sex?

We all know that sexual life between husband and wife can better promote the relationship between husband and wife, and can also meet the physiological needs between men and women. However, many women will find that their vaginas bleed after sex, which makes many women have a fear of sex life, and even worry about vaginal bleeding or infection of some gynecological diseases. If we understand the reasons, we can make timely adjustments. Let's understand what is the cause of vaginal bleeding after sex.

What causes vaginal bleeding after sex?

External genital tract injury

1. Damage to the hymen. The most common is rupture of the hymen during first sexual intercourse. This bleeding usually occurs during sexual intercourse. There may be pain and bleeding at the time, but the amount of bleeding is usually not much. If the injury is not serious, the bleeding will stop soon. However, sometimes when the rupture of the hymen happens to damage the blood vessels in that area, bleeding is heavy and requires pressure to stop the bleeding (such as using a clean cotton ball or gauze, a clean towel, etc.), or even going to the hospital for treatment.

2. Vaginal laceration. Vaginal bleeding occurs during or after sexual intercourse and the amount of bleeding is heavy, difficult to stop on its own, and lasts for a long time. Vaginal lacerations often occur during involuntary sexual intercourse or very rough sexual intercourse. Vaginal lacerations are also seen in vaginal malformations, such as vaginal septum, transverse septum, double vagina, and vaginal stenosis. If the vaginal wound heals poorly after vaginal plastic surgery, hymen repair, vaginal tumor removal surgery, or hysterectomy, sexual intercourse may easily cause damage. Improper sexual posture and position can also cause vaginal injury and bleeding. The amount of bleeding depends on the location and extent of the injury. There was a woman who, after being raped, suffered severe lacerations from the posterior vaginal wall to the vaginal vault and suffered heavy bleeding. She went to the hospital for treatment 6 hours later. When she did, she had already shown signs of hemorrhagic shock, including pale complexion, rapid pulse, and low blood pressure.

Inflammation of the external genital tract

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.

External malignant tumors:

1. Cervical cancer is one of the common causes of bleeding after sexual intercourse. Most cervical cancer patients do not have any discomfort symptoms in the early stages, and bleeding after sexual intercourse may be the only symptom of early cervical cancer. Rare vaginal cancer can also cause bleeding after intercourse. Therefore, if female friends find themselves having vaginal bleeding or bloody discharge after sexual intercourse, they should be alert and go to the hospital for examination as soon as possible to rule out whether they have gynecological malignancies such as cervical cancer.

2. 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 the most common. If vaginal bleeding occurs after intercourse, do not panic, go to the hospital as soon as possible, find out the cause of the bleeding, rule out malignant tumors such as cervical cancer, and receive timely treatment.

3. In case of menstrual abnormalities, you think that your period has ended and end up having sexual intercourse too early, which causes the uterus to contract under sexual stimulation and the blood remaining in the uterine cavity to be discharged from the vagina. In addition, a small number of women experience bleeding during ovulation. For this type of bleeding, if a gynecological examination shows no abnormalities in the vagina and cervix, the above possibilities should be considered.

The above is an introduction to what causes vaginal bleeding after intercourse. After understanding it, we know that there are many reasons for vaginal bleeding after intercourse. Female friends should not worry or be too anxious. When necessary, they should go to the hospital in time for physical examination and treatment.
