Sexual bulge
The protrusion of the embryo's side of the genital cusps during organ development ( organogenesis ) , which is caused by an overgrowth of the embryonic connective tissue ( mesenchyme ), is called a sexual bulge ( tuberculum labioscrotale ) .
In human fetuses, the outer labia are formed from the tubercula labioscrotalia in female individuals through remodeling processes . In the remaining female mammalian fetuses, the sexual bulges recede as far as possible, only in predators they remain in the form of the labial bulges . In male mammalian fetuses, the tubercula labioscrotalia form the scrotum .
