The labia majora are two cutaneous folds that form the lateral boundaries of the pudendal cleft. They originate from the mons pubis anteriorly and merge with the perineal body posteriorly (the posterior labial commissure). The subcutaneous fat is mainly deposited in the medial aspects, and so they tend to flatten out as they reach the perineal body. The lateral surfaces of the labia majora are adjacent to the medial surfaces of the thighs and are separated from them by a deep groove, the genitocrural or inguinal fold. The medial surfaces may be in contact with each other, but may be separated by the labia minora if they are large. The size of the labia majora varies considerably. The length of the labia majora and introitus has been shown to be positively correlated with body mass index but inversely correlated with age [5].
