You can have cervical erosion if you have never had children. This is because cervical erosion is a normal physiological phenomenon, mainly because women of childbearing age have a high level of estrogen secretion in their bodies, which leads to the outgrowth of the cervical columnar epithelium, and this outgrowth forms red granular changes on the surface of the cervix, which is similar to erosion to the naked eye, hence the name cervical erosion. This normal physiological phenomenon does not cause any clinical symptoms, so whether or not you have had children, as long as you are an adolescent woman or a woman of childbearing age, you will have cervical erosion. There is no need to be nervous about this phenomenon because it is just a phenomenon and not a symptom caused by a disease, as long as regular gynecological examinations are done clinically.
