Patient's question:
Please ask: Is cervical erosion definitely caused by Mycoplasma and Chlamydia infection? What are the actual causes of cervical erosion? Is it necessary to perform a Chlamydia and Mycoplasma test when the hospital conducts a check for cervical erosion? How do Chlamydia and Mycoplasma infections occur?First follow-up question: Please ask: Can vaginitis lead to cervical erosion?
Doctor's answer:
Hello: The formation of cervical erosion may be due to the following two reasons:① The so-called congenital erosion: During the late 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, surpassing the external os of the cervix. Approximately 1/3 of newborn girls retain this state, which resembles adult inflammatory cervical erosion in appearance, hence the term "congenital cervical erosion" ("congenital cervical erosion"). However, it generally persists for only a few days and naturally resolves after the estrogen levels from the mother decline.
② Cervical erosion caused by the proliferation of columnar epithelium of the cervical endometrium, which extends beyond the external os of the cervix. It appears similar to inflammatory cervical erosion but occurs only during the fertile age of ovary function and not during puberty or after menopause. It is more common during pregnancy and tends to resolve spontaneously after childbirth. Although patients may experience increased leukorrhea, it is clean mucus. Pathological examination shows no inflammatory cell infiltration under the columnar epithelium or only a few lymphocytes, with the characteristic histological features of papillary and glandular erosion 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 it 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 alter cervical epithelium.
