Penis agenesis: An extremely rare condition where a male is born without a penis. Penile agenesis (also known as Stern syndrome) 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. This birth defect shares the same gene locus as that of another rare gene disorder, Junger's hyperphallus, located on the long arm of the Y chromosome.
