Dimensions, Ratios, Volumes, and Weights of the Fatty Parts of the Vulva (Mons Pubis and Labia Majora)

Abstract

Abstract Background The anatomy of the fatty parts of the vulva, specifically the mons pubis and labia majora, has not been extensively studied. Objectives This study aimed to provide a comprehensive 3-dimensional picture of the mons pubis and labia majora by defining and measuring their dimensions. Furthermore, the study sought to calculate the different ratios, volumes, and weights of these structures. Methods The study included 214 women, who were divided into 2 groups based on their BMI. The researchers defined 27 dimensions to describe the width, height, and length of the mons pubis and labia majora, and specified the measuring methodology. Results The height of the mons pubis was approximately three-quarters of its length and half its width. The labia majora were wider and taller anteriorly than posteriorly, and their ratios decreased as they went posteriorly, from 4 to 2. The ratio of monal height to maximum labial height and to labial length was 3 and 1, respectively, whereas the ratio of monal width to the sum of maximum labial widths was nearly 1.5. The calculated volumes and weights of the mons pubis and labium majus were 200 mL, 30 mL, 180 g, and 27 g in Group 1, and 300 mL, 40 mL, 270 g, and 36 g in Group 2, respectively. Conclusions The dimensions, ratios, weights, and volumes defined and measured in this study can serve as the basis for any aesthetic measures involving the mons pubis and labia majora. Moreover, BMI and the different ratios should be considered in such measures.
