Penile duplication (PD), Diphallic terata, Diphallasparatus
Type of disease: Rare conditions
Diphallia, also called penile duplication (PD), diphallic terata, or diphallasparatus, is a rare condition in which a male infant is born with two penises. This is an extremely rare disorder with only approximately 100 cases of diphallia recorded since 1609. When diphallia is present, it is usually accompanied by other congenital anomalies such as renal (kidney), vertebral (spine), hindgut or anorectal (anus and rectum) duplication. There is also a higher risk of spina bifida. Infants born with PD and its related conditions have a higher death rate from various infections associated with their more complex renal or colorectal systems.
