What medical condition is defined as a duplicated penis?

Diphallia is the medical term used to describe the condition in which an individual is born with two penises. This rare congenital anomaly can vary in presentation, from having two fully formed organs to one that is incompletely developed. Diphallia can occur alongside various other urogenital anomalies, and its implications may involve complex medical and surgical considerations.

In contrast, kernicterus is associated with severe jaundice and brain damage due to elevated bilirubin levels in newborns; cryptorchidism refers to undescended testes; and hypospadias is a condition where the urethral opening is not located at the tip of the penis, but rather on the underside. Understanding these distinct conditions can help clarify why diphallia specifically pertains to the duplication of the penis.
