He's a US man in his mids, he goes by the moniker of Diphallic Dude and he was born with two penises. Yep, relly. The man was born with a condition called diphallia or penile duplication, a very rare occurrence in which a man is born with two penises. In the US, roughly 1 in 5. The condition is usually accompanied by a raft of other congenital issues.

Diphallia , penile duplication PD , diphallic terata , or diphallasparatus , is an extremely rare developmental abnormality in which a person is born with two penises. When diphallia is present, it is usually accompanied by renal , vertebral , hindgut , anorectal or other congenital anomalies. There is also a higher risk of spina bifida. It is thought diphallia occurs in the fetus between the 23rd and 25th days of gestation when an injury, chemical stress, or malfunctioning homeobox genes hamper proper function of the caudal cell mass of the fetal mesoderm as the urogenital sinus separates from the genital tubercle and rectum to form the penis.

By Alex Ward. A man who claims to suffer from an extremely rare medical condition in which he was born with two penises has posted a picture online, attracting thousands of questions. He claimed to suffer from a condition known as diphallia - where a boy is born with two fully-functioning penises, each capable of operating independently from the other - and included two pictures with the time and date.

Please view with discretion. Two penises on one organism might sound pretty wild, but did you know it can occur on humans as well? About 1 in 5. Though diphallia is fairly rare on its own, actually finding someone who has the condition is made even more difficult by the fact that it usually accompanies highly deleterious congenital conditions, such as other duplicated organs or spina bifida.
