The Hidden Dangers of Sexual Intercourse During Menstruation: What You Need to Know

Many people are aware that they should not have sexual intercourse during menstruation, but they may not know the harm it can cause. Here are a few points:

1. Both partners become aroused during sexual intercourse, and the insertion of the penis can cause increased blood flow to the female reproductive organs, leading to increased menstrual flow and a longer duration of menstruation.

2. During sexual intercourse during menstruation, menstrual secretions can enter the male urethra, which may lead to the development of urethritis.

3. During sexual intercourse during menstruation, the contraction of the uterus due to sexual arousal can cause fragments of the endometrium to be squeezed into the pelvic cavity, leading to endometriosis and infertility.

4. During sexual intercourse during menstruation, when sperm encounter damaged areas of the endometrium and blood cells, they may enter the bloodstream, which can trigger the production of anti-sperm antibodies, leading to immunological infertility.

5. During sexual intercourse during menstruation, bacteria from the male reproductive organs may enter the vagina. Menstrual blood provides a favorable environment for the growth of bacteria and other microorganisms. Bacteria can easily proliferate and spread along the small wounds and ruptured blood vessels in the endometrium, infecting the endometrium, and even affecting the fallopian tubes and pelvic organs, causing unnecessary trouble for the female partner.
