ABSTRACT: The present study aims to determine the gynecologic health status of asymptomatic women at a unique Japanese Health Check-up Institute, Ningen Dock. Medical records of Japanese women, who underwent gynecological medical (health) examinations between January 2011 and December 2016, were retrospectively reviewed. Of the cervical smears from 8927 women aged 18 - 85 years, 50 (0.6%) were classified as dysplastic and malignant changes: 18 of low-grade squamous intraepithelial lesion, 10 high-grade squamous intraepithelial lesion, 21 atypical squamous cells of undetermined significance and 1 cervical squamous cell carcinoma. No case of cervical adenocarcinoma was found. Ultrasonographic examination detected uterus enlargements and ovary tumors in 2.0% and 0.9% of cases, respectively. Most of participants (95.6%) revealed no gynecologic abnormalities. The present study based on the records of Ningen Dock, where asymptomatic participants undergo a medical examination at their own expense, showed very low incidence of abnormal cytologic and/or ultrasonographic findings.
