In mammals , the vagina is the elastic, muscular part of the female genital tract. In humans, it extends from the vulva to the cervix. The outer vaginal opening is normally partly covered by a membrane called the hymen. At the deep end, the cervix neck of the uterus bulges into the vagina. The vagina allows for sexual intercourse and birth. It also channels menstrual flow menses , which occurs in humans and closely related primates as part of the monthly menstrual cycle. Although research on the vagina is especially lacking for different animals, its location, structure and size are documented as varying among species.

Elongated labia also known as Sinus pudoris or macronympha  and albeit nonmedically, as khoikhoi apron or hottentot apron , are a feature of certain Khoikhoi people, whose female members develop relatively elongated labia minora , hanging up to four inches outside their vulva when they are standing in an upright position. The "apron" designation was apparently gained from the tendency of early European descriptions to misidentify the pair of labia as a single, wide organ, which they called, in French, a tablier , or "apron". This trait was first noted as far back as the 17th century, but became extensively documented in the last part of the 18th and the 19th century. For many years, the identification of Baartman was questioned because she demonstrated this feature. In the Gender and Science Reader , elongated labia minora were said to be portrayed by a "Negro. Labia may also be shaped by intentional labia stretching , usually done by an older aunt on girls beginning at the age of five, a practice that formerly fell into the category of Type IV female genital mutilation.
