The anatomical measurements of vulva in Indian women: A cross-sectional prospective study

OBJECTIVE 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. METHODS 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. RESULTS 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
