Patient's question:
What are the harms of having sex during menstruation? First question supplement: Why didn't I have menstrual blood after having sex during my period? Today is the third day of my period, is it because I had sex during my period?Doctor's answer:
Menstruation is a physiological phenomenon unique to women. During the menstrual period, various changes occur in the body, the most prominent of which are: a decrease in the excitability of the cerebral cortex and a weakened immune response throughout the body; the shedding of the endometrium in the reproductive organs, leading to bleeding, the opening of the uterine cervix, and the neutralization of the vaginal acidic environment by alkaline menstrual blood, which reduces vaginal acidity and weakens the natural barrier function. If sexual activity occurs during menstruation, the following adverse consequences may arise:First, due to mutual excitement, the insertion of the penis may cause congestion in the female reproductive organs, leading to increased menstrual flow and prolonged periods.
Second, during sexual intercourse at this time, the male reproductive organs may introduce bacteria into the vagina. Menstrual blood serves as an excellent breeding ground for bacteria and other microorganisms, which can easily multiply and spread along the numerous small wounds and broken capillaries in the endometrium, potentially infecting it and even affecting the fallopian tubes and pelvic organs, causing unnecessary complications for the woman.
Third, menstrual secretions entering the male urethra may also lead to the development of urethritis.
Fourth, sexual intercourse during menstruation can cause sperm to encounter endometrial fragments at the site of damage or even enter the bloodstream, potentially triggering the production of antisperm antibodies. This may result in immunological infertility or subfertility.
Fifth, during sexual intercourse during menstruation, uterine contractions during sexual arousal may push endometrial fragments into the pelvic cavity, leading to endometriosis and potentially causing infertility.
Therefore, for the health and fertility of both partners, sexual intercourse during menstruation should be strictly avoided under all circumstances.
