What causes bleeding after menstrual intercourse?

Women have menstrual periods due to physiological reasons, which usually last from 5 to 7 days. In this case, it is inevitable that they will have sexual intercourse during the menstrual period. Some women have no reaction after sexual intercourse, but some women will have abnormal conditions after sexual intercourse, and bleeding is one of the manifestations. So what is the cause of bleeding after sexual intercourse during the menstrual period? Let’s take a brief look at it below.

Menstruation has not really finished yet, and it is inevitable to have sex before the menstruation is over. If you have sex during menstruation, the following adverse consequences will occur:

1. Due to the excitement of both parties, the insertion of the penis will cause the female genitals to become congested, leading to increased menstrual volume and prolonged menstruation;

2. During menstruation, menstrual secretions enter the male urethra and may also cause urethritis;

3. Having sex during menstruation may cause the uterine cavity to contract during sexual impulse, which may squeeze endometrial fragments into the pelvic cavity, causing endometriosis and leading to infertility.

4. Having sex during menstruation may cause sperm to meet the spilled blood cells at the damaged endometrium and even enter the blood, which may induce the production of anti-sperm antibodies, leading to immune infertility and sterility.

5. Having sex during menstruation may cause the male reproductive organs to bring bacteria into the vagina. Menstrual blood is a good breeding ground for bacteria and other microorganisms. Bacteria can easily multiply and spread along the many tiny wounds and ruptured blood vessels in the endometrium, infecting the endometrium and even affecting the fallopian tubes and pelvic organs, thus causing unnecessary trouble to the woman. You don't need to worry if there are no other symptoms after the menstruation is over.

Through the above introduction, we know about bleeding after sexual intercourse during menstruation. Therefore, women should not have sexual intercourse during menstruation, because women's body resistance decreases at this time, which may lead to the risk of gynecological diseases. At the same time, men should also restrain themselves during this period and not do things that hurt women.
