ABSTRACT
The female external genitalia are described as the vulva, which is bordered by the mons veneris anteriorly and the labio-crural folds posterolaterally. The introitus tends to be open in parous women but otherwise appears closed by the apposing labia majora. The labia minora are folds of skin that fuse anteriorly to form the clitoris, which contains erectile tissue similar to the penis. The fourchette is the posterior part of the introitus, which must stretch considerably to allow the delivery of a baby.
