Measurements of female genital appearance in Chinese adults seeking genital cosmetic surgery:apreliminary report from a gynecological center

Objective To measure the external genitalia in Chinese female adults seeking genital cosmetic surgeries and to evaluate the relationship of female external genitalia and general demographic details.Methods Our study design recruited 319 females referred to the out-patient clinic from August 2010 to August 2013.From each individual we measured 16 parameters,analyzed the differences between married and unmarried group and accessed the significance of variations in age,height,weight and BMI.Results The primary parameters were as follows:clitoral prepuce length(25.66±4.42)mm,perineal body length(24.56±4.2)mm,labia minora length(47.99±5.82)mm,labia minora width of left side(19.92±8.46)mm,labia minora width of right side(21.26±8.71)mm,labia majora length(75.71±5.22)mm,labia majora width(20.53±4.11)mm.The range of labia minora width(3~45mm)was wide.Compared with unmarried women,Perineal body length 24.2 mm decreased(P=0.048),while apex to perineum(bilateral)and labial length(apex to perineum of left side:49.5mm,apex to perineum of right side 51.5mm,labia minora:49.2mm increased(P=0.005,0.006)in those married.Labia minora length was associated with height(β=-0.24,P=0.018),and weight(β=0.28,P=0.0009).Labia majora length was associated with weight(β=0.30,P=0.0003).Conclusions We presented an external genitalia database of Chinese female adults seeking gynecological cosmetic surgeries.Although the ranges of genital measurements vary,clitoral prepuce length and perineal body length were in the same scope.There are differences between married and unmarried groups which should be paid attention in surgical designs and genital esthetic evaluation.
