Excessive masturbation does not usually lead to menstrual disorders, but excessive masturbation may lead to adverse reactions such as urethritis and pain in the lower abdomen. Excessive masturbation does not cause patients to develop menstrual disorders because masturbation is a way for women to act as a sexual release and does not affect the menstrual cycle. However, excessive masturbation may lead to urethritis because the patient’s vulva may be repeatedly rubbed, allowing bacteria to enter the urethra and develop urethritis. Excessive masturbation can also lead to uterine spasms, and patients may experience pain in the abdomen. When patients experience menstrual disorders, they may be caused by endometrial polyps, polycystic ovary syndrome, uterine fibroids and other diseases. Patients with endometrial polyps will have irregular menstruation, abnormal vaginal bleeding and other symptoms, patients with polycystic ovary syndrome will have menstrual disorders, hirsutism and other symptoms, and patients with uterine fibroids will have abnormal menstruation, pelvic pain and other symptoms. Excessive masturbation does not cause menstrual disorders, and it is recommended to correct the habit of excessive masturbation. When patients have symptoms of menstrual disorders, they should consult a doctor in time to find out the cause of the disease and follow the doctor’s instructions for treatment.
