Why can't you share a bed during your period?

Patient's question:

Why can't you share a bed during your menstrual period

Doctor's answer:

(1) It can easily cause various inflammations, such as endometritis, salpingitis, pelvic inflammatory disease, and even infertility.
(2) Intercourse during menstruation can cause uterine contractions, which may allow menstrual blood to enter the abdominal cavity, increasing the risk of endometriosis.
(3) During menstruation, some sperm and other components of semen may enter a woman's bloodstream through small blood vessel tears, stimulating the immune system to form anti-sperm antibodies, leading to immunological infertility.
(4) Various blood-borne infectious diseases can be transmitted between partners.
(5) Intercourse during menstruation may cause increased bleeding or prolonged bleeding duration. It is best to avoid this situation as much as possible. If it happens occasionally and there are no other abnormal symptoms, it is usually not a major issue—just wait and see, and avoid treatment for now. Don’t worry. You’re lucky this time, but frequent occurrences may lead to the problems mentioned above. Please pay attention to avoiding this situation as much as possible.
