Clitoromegaly (or macroclitoris ) is an abnormal enlargement of the clitoris (not to be confused with the normal enlargement of the clitoris seen during sexual arousal).
Although clitoromegaly denotes just a clitoris larger than expected (thus involving some uncertainty about what can be defined as normal), it is commonly seen as a congenital anomaly of the genitalia.
In Atlas of Human Sex Anatomy (1949) by Dr. Robert Latou Dickinson, the typical clitoris is defined as having a crosswise width of 3 to 4 mm. (0.12 - 0.16 inches) and a lengthwise width of 4 to 5 mm (0.16 - 0.20 inches). On the other hand, in Obstetrics and Gynecology medical literature, a frequent definition of clitoromegaly is when there is a CI of greater than 35 mm2 (0.05 inches2), which is almost twice the size given above for an average sized clitoral hood.
