Penile agenesis: a report of six cases

Agenesis of the penis is an extremely rare anomaly, occurring only once in 30 million births. This low incidence is responsible for the limited experience with this anomaly. There are only about 70 published cases, most reports being of one or two patients. This complex malformation requires urgent assessment at birth for several reasons: Female sex assignment is required early. Gonadectomy should be performed in the first few days of life to prevent male gender sex marking from the testosterone surge occurring between the tenth and the 60th day of life. Early gonadectomy and genital reconstruction helps the family to accept the child's altered gender and to reduce psychological problems.
