The occurrence of dysmenorrhea is related to the stimulation of prostatic hormones secreted by the endometrium, and may also be related to the cold and chill in the abdomen during menstruation, resulting in poor discharge of menstrual blood and causing dysmenorrhea, which has little effect on sexual life. However, if you have sex during menstruation, it may cause the endometrium to shed to other places and cause endometriosis, which may cause dysmenorrhea. Also the symptoms of dysmenorrhea after sexual intercourse may also be the result of cervical inflammation. It is advisable to go to the hospital for routine gynecological examination and hysteroscopy to exclude organic lesions, in addition to make sure to actively treat inflammation and avoid sexual intercourse during menstruation.
