To measure the anatomical dimensions of the vulva in adult Indian women. To analyze their correlations with age, body mass index (BMI), parity, and mode of delivery.
This cross-sectional study was conducted in a tertiary care university hospital in India, among 400 women aged 18 years and above. Various vulval measurements were taken, and Pearson's correction was applied to variables like age, BMI, parity, and mode of delivery.
Mean length of glans of clitoris was 5.2 ± 1.43 mm, the labia minora width was 2.6 ± 0.74 cm, length of introitus was 1.3 ± 0.59 cm, and perineal body length was 2.3 ± 0.60 cm. The range of some measurements was extensive, for example labia minora width ranged from 0.7 to 4.9 cm. Normal centile curves were constructed for vulval measurements according to age groups. Statistically significant positive correlations of age, BMI, and obstetrical history were seen with labia minora width (r = 0.165, P = 0.001; r = 0.284, P < 0.001; r = 0.246, P < 0.001, respectively).
The centile curves can be used as a reference for the Indian population of different ages. These can be used when counseling women coming for female genital cosmetic surgery.
测量成年印度女性外阴的解剖学尺寸。分析其与年龄、体重指数（BMI）、产次和分娩方式的相关性。
这项横断面研究在印度一家三级护理大学医院对400名18岁及以上的女性进行。进行了各种外阴测量，并对年龄、BMI、产次和分娩方式等变量应用了Pearson校正。
阴蒂头平均长度为5.2±1.43毫米，小阴唇宽度为2.6±0.74厘米，阴道口长度为1.3±0.59厘米，会阴体长度为2.3±0.60厘米。一些测量值的范围较广，例如小阴唇宽度范围为0.7至4.9厘米。根据年龄组构建了外阴测量的正常百分位数曲线。年龄、BMI和产科病史与小阴唇宽度存在统计学上显著的正相关（分别为r = 0.165，P = 0.001；r = 0.284，P < 0.001；r = 0.246，P < 0.001）。
百分位数曲线可作为不同年龄印度人群的参考。在为寻求女性生殖器整形手术的女性提供咨询时可使用这些曲线。
