Why can't you have sex during menstruation?

Some female friends do not know the common sense of health, and if they have sex with their male partners during their menstrual period, it is actually harmful to both parties. Because women's immunity decreases during menstruation, the uterus is easily infected by bacteria during intercourse, and there is also a chance of infection for men.

1. Having sex during menstruation can easily cause bacterial infection. During menstruation, the endometrium sheds and forms a wound, and the cervix is ​​also slightly dilated. Furthermore, due to the discharge of menstrual blood, the acidic environment in the vagina is diluted and the self-cleaning ability of the vagina is weakened. At this time, during sexual intercourse, the male reproductive organs will bring in bacteria, infect the endometrium and cause pelvic inflammation, causing pain to the woman. Some women will experience recurrence a few days after their period ends. In this case, you should be extra careful to avoid contamination during sexual intercourse. In addition, it should be noted that you should not have sexual intercourse during menstruation even if you use condoms, because condoms can only prevent sperm from entering the vagina, but cannot prevent bacteria from entering the vagina.

2. Having sex during menstruation may lead to infertility, because sperm meets the damaged endometrium and overflowing blood cells and even enters the blood, which can cause allergies of immune cells during menstruation and stimulate the body to produce anti-sperm antibodies. This antibody can exist in female cervical mucus and serum. Once the sperm antibody comes into contact with sperm again, it will stimulate the body's immune rejection reaction, thereby affecting the combination of sperm and egg and causing infertility.

3. Having sex during menstruation may cause menstrual secretions to enter the male urethra and may also cause urethritis.

4. When a woman has her menstrual period, the endometrium bleeds, part of the endometrium ruptures and falls off, and some blood vessels are open and exposed. Having sex at this time will cause local stimulation and increase the amount of menstruation, or even prolong the period and aggravate the discomfort symptoms of menstruation.
