vulv/o or episi/o is a combining form that refers to “vulva”.
An outer part of a female’s genital system is the vulva. There are three parts to the vulva: the opening of the vagina, the labia majora (outer lips), and the labia minora (inner lips). In addition to protecting female reproductive organs (labia majora and minora), the vulva also plays a role in sexual arousal and stimulation (clitoris) and facilitates sex through the provision of lubrication (Bartholin’s glands) and cushioning (mons pubis).
