Penile agenesis

**Penile agenesis**
*Classification & external resources*
ICD-9	752.69

Penile agenesis is a very rare birth defect in humans, occurring about once in 20 million births, where a male child is born without a penis. It is also known as aphallia [from the Greek, "a" for negative or no, and "phallia" for penis]. Most patients have no known family history of aphallia, and often have a normal male anatomy, save for the absence of the penis.
