Can sexual arousal during menstruation cause endometriosis?

Sexual arousal during menstruation generally does not cause endometriosis. However, if sexual intercourse occurs during menstruation, it may lead to problems such as dysmenorrhea, increased menstrual flow, and prolonged periods, and could even trigger vaginitis or urethritis. Therefore, it's important to maintain good personal hygiene during menstruation, frequently change sanitary pads, keep the abdomen warm, and avoid consuming raw, cold, or irritating foods. At the same time, sexual activity should be avoided during menstruation, as well as strenuous exercise.
