Patient's question:
Is cervical erosion definitely caused by Mycoplasma and Chlamydia infections? What are the actual causes of cervical erosion? Is it necessary to perform Chlamydia and Mycoplasma tests when the hospital conducts a check for cervical erosion? How do Chlamydia and Mycoplasma infections occur?First follow-up question: Does vaginitis lead to cervical erosion?
Doctor's answer:
Hello: The formation of cervical erosion may still have the following two reasons: ① The so-called congenital erosion: In the later stage of embryonic development, both the vagina and the vaginal part of the cervix are covered with transitional epithelium. By the sixth month, this epithelium extends into the cervical canal, and by full term, the columnar epithelium of the cervical canal mucosa grows outward, exceeding the external os of the cervix. About 1/3 of newborn girls maintain this state, and their appearance is similar to that of adult inflammatory cervical erosion, hence the term "congenital cervical erosion" ("congenital cervical erosion"). However, it generally persists for only a few days and naturally regresses after the estrogen level from the mother decreases. ② Cervical erosion caused by the proliferation of columnar epithelium of the cervical endometrium, which exceeds the external os of the cervix, appears similar to inflammatory cervical erosion but occurs only during the fertile age of ovarian function and not during puberty or after menopause. It is more common during pregnancy and tends to regress spontaneously after childbirth. Although patients may experience an increase in leukorrhea, it is clean mucus. Pathological examination shows no inflammatory cell infiltration under the columnar epithelium or only a few lymphocytes, and it is characterized by the papillary and glandular erosion tissue patterns mentioned earlier. All these phenomena suggest that the formation of this type of erosion may be due to an imbalance in sex hormone levels and is unrelated to inflammation. Inflammation may only occur as a secondary complication on the basis of erosion, but this is merely a consequence rather than the cause of erosion. Erosion may be due to the effects of estrogen, but some animal experiments have found that injecting testosterone leads to changes similar to human glandular erosion. Therefore, it is believed that androgens can cause changes in cervical epithelium.
