Clitoral erection

Clitoral erection (also known as clitoral tumescence or female erection)[1][2] is a physiological phenomenon where the clitoris becomes enlarged and firm.

Clitoral erection is the result of a complex interaction of psychological, neural, vascular, and endocrine factors, and is usually, though not exclusively, associated with sexual arousal. Erections should eventually subside, and the prolonged state of clitoral erection even while not aroused is a condition that could become painful.[3] This swelling and shrinking to a relaxed state seems linked to nitric oxide's effects on tissues in the clitoris, similar to its role in penile erection.[4]

Medical conditions[edit]

Clitoral priapism[edit]

Priapism, while more common in males, is a condition that can also affect the clitoris.[3] Symptoms include painful engorgement, swelling, and pain in the area around the clitoris.[11]

Other animals[edit]

Among capuchin monkeys, clitoral erection is possible and makes the clitoris more visible than in its relaxed state where it is hidden by a preputial fold.[12]
