The question of whether sexual intercourse during menstruation will lead to pregnancy reflects the close relationship between sexual intercourse during menstruation and pregnancy. It also reflects the sexual psychology and sexual physiology of both men and women who hope for temporary pleasure. Regarding the question of whether having sex during menstruation will lead to pregnancy. Gender health experts point out that it is relatively difficult to get pregnant if you have sex during menstruation, but in real life there are cases of pregnancy during sex.

Sexual intercourse during menstruation is a choice at the stage of sexual intercourse, because the interest and impulse of sexual intercourse between men and women are uncertain. In addition, many men and women do not want the comfort of condoms, so they often have the desire for sex during menstruation, but they are worried that having sex at this stage will lead to pregnancy. Most people believe that there is no need to worry about getting pregnant if you have sex during menstruation. But the fact is: there is indeed a precedent for pregnancy caused by intercourse during menstruation.

The reason why I think this is mainly due to irregular ovulation. Most women ovulate around the 14th day after the start of menstruation, but if the ovulation period is advanced and the sperm vitality is strong, pregnancy is likely to occur. The average number of sperm in a male's sexual intercourse is about 300 million. These sperm can survive in the female body for about 3 days. If the female ovulates early, it is very possible to become pregnant. Therefore, even if the relationship is consensual, necessary contraceptive measures must be taken during menstrual intercourse.

Since women’s body resistance is weak during menstruation, sexual intercourse may cause the reproductive system to become susceptible to infection, reverse flow of endometrium into the pelvic cavity causing endometriosis, and cause women to not become pregnant. Therefore, it is not recommended to have sexual intercourse during menstruation. This avoids the possible harm caused by having sex during menstruation.

Why women can’t have sex during menstruation

The first reason why women cannot have sex during menstruation is to prevent reproductive system infections

When a woman gets her period, the endometrium (the layer of tissue inside the uterus) peels off piece by piece. When women have sexual intercourse during menstruation, it is easy for bacteria from around the vulva and perineum (the area between the vaginal opening and the anus) to be introduced into the vagina, cervix and even into the uterus. The bacteria grow and multiply in the place where there is blood, causing inflammation on the spot. It is called endometritis, which not only causes fever and lower abdominal pain, but also increases menstrual bleeding and prolongs menstrual periods.

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. In this case, it will not only cause fever and abdominal pain, but also possible affect future fertility. Once the fallopian tube becomes inflamed, adhesion may occur. In severe cases, the tube lumen may be blocked, and sperm cannot pass through, resulting in infertility.

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 (under normal circumstances, the endometrium flows outside with the menstrual blood during menstruation)

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 in the uterine cavity can enter the fallopian tube with the pressure of uterine contraction, and enter the abdominal cavity, pelvic cavity, etc. along the fallopian tube. Wherever it falls and grows, endometriosis will occur.

This disease can cause adhesion 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 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.

How many days after menstruation can I have normal intercourse?

The issue of being able to have sex a few days after menstruation reflects the urgency of men and women to have sex after menstruation, as they are worried about the possible harm caused by having sex early after menstruation. Therefore, the issue of being able to have sex within a few days after menstruation has attracted much attention. So how many days after menstruation can I have sex? Gender health experts point out: Under normal circumstances, it is recommended to have intercourse three days after menstruation is clear, so as to avoid a series of hazards of early intercourse.

Young men and women or newlyweds always show strong sexual desire, but during the female menstrual period, both parties will be extremely patient. Therefore, many men and women can’t wait to return to normal sex life just after menstruation. Little do they know that such behavior has great harm not only to men but also to female friends.

If you have sexual intercourse in a hurry just after menstruation has stopped, it may cause congestion in the uterine cavity, forcing the lining of the uterine cavity to bleed again, and vaginal bleeding. During sexual intercourse, bacteria attached to the male vaginal meridian, urethra, and female vaginal opening can As these enter the female reproductive tract, infection of the reproductive organs may occur, which may also cause damage to the endometrium that has not yet recovered.

Therefore, in order to avoid the series of harms caused by early sexual intercourse after menstruation, men and women should not have sexual intercourse immediately after menstruation. Under normal circumstances, normal sexual life should be resumed 3 days after each menstruation, which is more beneficial to women's reproductive health. If it may cause menstrual cramps in the first two days after menstruation, the harm still exists.
