What are the causes of vaginal bleeding after sex?

We often encounter embarrassing things during sex, that is, vaginal bleeding after sex. Many patients will have questions, what is the cause of vaginal bleeding after sex? In fact, there are two main causes of vaginal bleeding after sex, physiological and pathological. Different diseases require symptomatic treatment to control the condition. In order to let patients more clearly understand the causes of vaginal bleeding after sex, let us take a closer look.

Physiological causes

1. Most of the bleeding during female sexual intercourse is caused by organic diseases of the reproductive system, and only a few are caused by rough male movements or improper sexual intercourse. The first night of marriage; the first sexual intercourse, bleeding due to rupture and damage of the hymen, generally the amount of bleeding is small, only a few people have thick hymen, and the man's movements are too rough, which can cause more bleeding.

2. In elderly women, due to atrophy of gonads, the secretion of sex hormones decreases, the vagina atrophies, the vaginal epithelium becomes fragile, the tissue becomes fibrotic and lacks elasticity, the vaginal exudate becomes less and becomes dry, and rough movements, forced insertion, and improper sexual intercourse during intercourse can also cause vaginal injury, rupture of blood vessels and bleeding.

3. For pregnant women, during the first and last three months of pregnancy, sexual intercourse stimulates the cervix, causing violent contractions of the uterus and bleeding during sexual intercourse. A small number of women even suffer miscarriage or premature birth as a result. Special attention should be paid.

4. Vaginal hypoplasia, narrow or deformed vagina. Rough movements during sexual intercourse may cause lacerations of the vaginal wall or posterior fornix, resulting in vaginal bleeding.

5. Organic lesions in the female reproductive tract can often lead to bleeding during sexual intercourse. For example, vulvar ulcers can cause friction on the ulcer surface during sexual intercourse, causing pain and bleeding. Vaginitis is caused by the massive shedding of the vaginal epithelium and congestion of the vaginal mucosa. During sexual intercourse, the penis thrusts and rubs in the vagina, causing damage, rupture and bleeding of the vaginal mucosa. The urethral caruncle grows at the female urethral opening. Because of its brittle texture, the slightest touch during sexual intercourse can cause bleeding. Cervical erosion is caused by the exfoliation of the epithelium around the external os of the cervix, which exposes the fragile subcutaneous tissue and forms an eroded surface. During sexual intercourse, the impact of the penis causes bleeding. Due to the infiltration of cancer cells, cervical cancer tissue becomes fragile and often causes contact bleeding during sexual intercourse. The urethra and vagina are adjacent to each other. When the urethra is inflamed, it is easily squeezed and injured during sexual intercourse, causing bleeding.

6. Virgin. Because there is a layer of flesh membrane during the first sexual intercourse. Sexual intercourse will pierce. It will bleed.

Causes

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.

Reasons for IUD insertion

The main reason for bleeding during sexual intercourse after IUD insertion is that the intrauterine ring is a foreign body in the uterine cavity. Its mechanical compression can cause local damage, necrosis and ulcers of the endometrium. The stimulation of sexual intercourse will inevitably cause bleeding. However, generally after a period of time, the bleeding will ease or disappear after the body adapts to the contraceptive ring. However, bleeding during intercourse always occurs after IUD insertion, so you should be vigilant against infection and other adverse conditions.

Other reasons

1. Abnormal cervical development: Abnormal cervical development is a sign of cervical epithelial cell cancer. Having multiple sexual partners, having intercourse before age 18, becoming pregnant before age 16, or having a history of sexually transmitted diseases can increase the likelihood of abnormal cervical development. It is usually treated by performing a cold surgery.

2. Chlamydia infection: The viral infection is usually transmitted through sexual intercourse and with sperm, vaginal fluid or blood.

The causes of vaginal bleeding after intercourse are complex. If a patient finds vaginal bleeding after intercourse, she should observe whether she has her menstruation and whether she has any abnormal symptoms such as pain in the body. If she cannot diagnose herself, she should go to the hospital for examination. The cause of vaginal bleeding after intercourse can be confirmed through examination. The patient can receive symptomatic treatment, and after confirming that the bleeding is caused by a disease, relevant treatment can be formulated according to the condition.
