The hood of the vagina is not a term used in anatomy. However, the clitoral hood is a fold of skin that surrounds the head of the clitoris. It is also referred to as the upper part of the labia and is technically part of the vulva. The clitoral hood protects the clitoris from friction or rubbing and varies widely in appearance from person to person. It can affect sexual pleasure, and its size and thickness can vary. The clitoral hood is also important in pleasure, as its tissue forms part of the erogenous zones of the vulva. If a person is not happy with how their clitoral hood looks, surgery is an option.
