Can you get pregnant if you have sex during menstruation

　1. Prevent reproductive system infections

When a woman has her menstruation, the uterine endometrium (the layer of tissue inside the uterus) peels off piece by piece. Women During menstrual intercourse, it is easy for women to bring germs from around the vulva and perineum (the area between the vaginal opening and anus) into the vagina, cervix and even into the uterus. The bacteria grow and multiply in the place where there is blood. Inflammation occurs on the spot, which is called endometritis. Not only will there be fever and abdominal pain, but also increased menstrual bleeding and prolonged menstrual period.

If the infected bacteria are very virulent, they may spread to the outside of the uterus through the lymphatic vessels in the endometrium and enter the pelvic cavity, causing acute adnexitis (including fallopian tubes and ovaries) and pelvic peritonitis. This will not only cause fever and abdominal pain, but may also affect future fertility. Once the fallopian tube becomes inflamed, adhesion may occur. In severe cases, the tube lumen may be blocked. Sperm cannot pass through and pregnancy cannot occur.

2. Prevent the reflux of endometrium into the pelvic cavity causing endometriosis (Under normal circumstances, the endometrium flows out with menstrual blood during the menstrual period)

If you have sex during menstruation, when the woman's excitement reaches its peak, the uterus will contract. At this time, the endometrial fragments that have fallen off the uterine cavity can enter the fallopian tube with the pressure of uterine contraction, and enter the abdominal cavity and pelvic cavity along the fallopian tube. No matter where they fall and grow, endometriosis will occur.

This disease can cause adhesion between the fallopian tubes, the uterus, and the pelvic cavity, and can also cause ovarian surface hypertrophy and blood retention. It can not only destroy the normal development and growth of eggs, but also affect ovulation, so it will eventually cause infertility. Therefore, it is not advisable to have sexual intercourse during menstruation.

In short, sexual intercourse during menstruation is harmful to women's health, and adolescent women should be especially careful. At this point, both men and women cannot seek temporary pleasure and leave lifelong regrets.
