Why can't I have sex when my period comes?

Why can't you have sex during menstruation? In fact, there are a few days every month when couples must not have sex, that is, the days when women have their period, but many people are confused, why can't you have sex during menstruation? In fact, the female menstrual period is a crucial time for women every month. Many people think that having sex during menstruation can prevent pregnancy, but do you know? If you have sex at this time, will it cause various adverse effects?

Menstruation is a physiological phenomenon unique to women. During the menstrual period, some changes occur in various parts of the human body. Among them, the most prominent change is: the regulation of cerebral cortex fluid decreases, and the body's resistance is weaker than usual. The uterine wall in the vagina falls off and bleeds, the cervix opens, and the alkaline menstrual fluid combines the acidic and alkaline environment in the vagina, reducing the acidity in the vagina and weakening the natural barrier function.

If you have sex during menstruation, the following adverse effects will occur:

1. Due to the mutual excitement, the insertion of the penis will cause female genital hematoma, resulting in increased menstrual flow and prolonged menstruation.

2. If you have sex at this time, the male reproductive organ may bring bacteria to the female vagina. Menstruation is an excellent culture medium for bacteria and other microorganisms. Bacteria are easy to grow and spread along the numerous tiny wounds and broken blood vessels in the uterine wall, infecting the uterine wall and even invading the fallopian tubes and pelvic organs, causing unnecessary inconvenience to women.

3. Menstrual secretions enter the male urethra and may also cause urethritis.

4. Sexual intercourse during menstruation, because male sperm meets zinc oxide oil in the uterine wall and overflowed red blood cells, and even enters the blood, it can cause the formation of anti-sperm antibodies, thereby causing immune infertility and sterility.

5. Having sex during menstruation, because of uterine contractions during sexual excitement, it is possible that fragments of the uterine wall may be squeezed into the pelvis, causing endometriosis and infertility.

Therefore, for the sake of each other's health and future, don't make exceptions. If necessary, you can use other methods to solve the problem. But no matter what the circumstances, sexual intercourse during menstruation should be strictly prohibited.
