Can masturbation in menstrual cycle lead to pelvic adhesion or endometriosis?

Long-term masturbation can cause some gynecological diseases, such as pelvic inflammatory disease, vaginitis, cervicitis, cervical erosion and so on. Long-term repeated pelvic inflammatory disease may cause pelvic adhesion. If you masturbate only occasionally, it may not cause gynecological diseases. Endometriosis refers to the growth of endometrium in other parts, causing periodic bleeding similar to menstrual cycle. Masturbation does not cause endometriosis, which is mostly related to genes.
