RÉSUMÉ
Objective@#To collect preliminary data of normal Chinese female genital appearance, to compare the parameters of Han and Uygur nationality, and to present the preliminary data for normal female external genitalia database.@*Methods@#This study design recruited healthy females referred to the out-patient clinic for physical examination from October 2014 to March 2015 in Xinjiang Petroleum Geological Survey Department Staff Hospital. The recruitment was based on rigid inclusion and exclusion criteria. Demographic data consists of nationality, age, height, weight, marital status, gravidity, parity, vaginal delivery, and intercourse frequency. Anthropometric measurements were taken in 234 females of Han group whereas 278 females of Uygur group. For each individual 16 parameters were measured. The external genitalia appearance in Han and Uygur nationality was compared. The significance of variations in age, height, weight, BMI, gravidity, parity, vaginal delivery and intercourse frequency were analyzed.@*Results@#Primary measurements of Han and Uygur nationality are presented as mean (95% confidence interval). There are many differences in female genital appearance between Han and Uygur nationality. Several parameters were statistically associated with age, BMI, gravidity, parity, vaginal delivery and intercourse frequency. The females with complete labial asymmetry account for 5.6%(13/234) and 5.8%(16/278) in Han and Uygur normal adults, respectively.@*Conclusions@#This study presented the external genitalia measurements of normal Chinese female adults in Xinjiang, thus providing the preliminary data for normal female external genitalia database. Females of Han and Uygur nationality have multiple differences in external genitalia appearances. The parameters are associated with age, BMI, gravidity, parity, vaginal delivery, and intercourse frequency. The labial asymmetry is a universal phenomenon.
