The Authors have examined the results of 14.703 colposcopic examinations performed at the Social Medicine Center of the Province of Florence between 1974 and 1978, grouping the women according to childbearing and age. The purpose was to verify if mechanical and traumatic factors related to delivery may be responsible for modifications of the epithelial lining of the uterine cervix and especially for ectopy. The Authors have shown that the percentage of incidence of colposcopic picture of portio with original squamous epithelium and ectopy maintain almost identical values in nulliparae and pluriparae. Delivery does not significantly influence the presence of ectopy: the slight increase of such a picture in pluriparae is attributed to the formation of "ektropion", and the Authors define this picture, clearly separating it from the ectopy picture. The presence of ectopy decreases considerably as the women's age increases: this is attributed to therapeutic treatments possibly undergone over the years and to the spontaneous mending processes which are completed with age. Ectopy and its typical transformation zones are found in high percentages in the age group of women under 20. This corresponds exactly to the percentages reported by a few Authors on the presence of jodonegative zones in newborns. On the basis of these results, the Authors conclude that delivery does not modify the condition of the uterine cervix and deny any relation between traumatic factors and "cervical erosion".
作者们检查了1974年至1978年间在佛罗伦萨省社会医学中心进行的14703例阴道镜检查结果，根据生育情况和年龄对女性进行分组。目的是验证与分娩相关的机械和创伤因素是否可能导致子宫颈上皮衬里的改变，尤其是导致异位。作者们表明，原始鳞状上皮和异位的阴道镜图像在未生育女性和多产女性中的发生率几乎相同。分娩对异位的存在没有显著影响：多产女性中这种图像的轻微增加归因于“外翻”的形成，作者们明确将这种图像与异位图像区分开来定义。随着女性年龄的增加，异位的存在显著减少：这归因于多年来可能接受的治疗以及随着年龄增长而完成的自然修复过程。在20岁以下的女性年龄组中，异位及其典型的转化区发现比例很高。这与一些作者报道的新生儿中碘阴性区的比例完全一致。基于这些结果，作者们得出结论，分娩不会改变子宫颈的状况，并否认创伤因素与“宫颈糜烂”之间存在任何关系。
