During a 6 1/2 year study period the author used colposcopy to evaluate 174 pregnant patients with abnormal cervical cytology. Of these patients, 42% had an exocervical squamocolumnar junction. In those patients beyond the age of 25, or with a parity greater than 1, 80% had endocervical junctions. The predominant effect of pregnancy is to stimulate endocervical migration of this junction.
在为期6年半的研究期间，作者使用阴道镜检查对174例宫颈细胞学异常的孕妇进行了评估。在这些患者中，42%有宫颈外鳞状柱状交接部。在年龄超过25岁或产次大于1的患者中，80%有宫颈管内交接部。妊娠的主要作用是刺激该交接部向宫颈管内迁移。
