Can sex during menstruation lead to pregnancy?

　　female The first reason not to have sex during menstruation: to prevent reproductive system infections

　　Women's menstruation Uterus The endometrium (the layer of tissue inside the uterus) peels off piece by piece. When women have sexual intercourse during menstruation, it is easy 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 does it appear fever ,Down stomach ache , and menstrual bleeding increases and the menstrual period is prolonged.

　　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, and in severe cases, the lumen may be blocked. sperm If it cannot pass, conception cannot occur.

　　The second reason why women cannot have sex during menstruation is to prevent the endometrium from flowing back into the pelvic cavity and causing endometriosis (normally, the endometrium flows out with menstrual blood during menstruation)

　　For example, 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, endometriosis will occur.

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

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