Diphallia: When A Man Has Two Penises

Diphallia is defined as a condition of having more than one penis. One might say any man who has this condition will do really well in the porn industry but some cases have accompanying medical issues that the men who were born with this have actually opted to have the other one removed.

 "There is nothing comical about this rare disorder that has only occurred in 100 cases since first discovered by Johannes Jacob Wecker in 1609. Only one in 5.5 million men have a chance of being born with this disorder. Penile agenesis, the absence of a penis, only occurs in 30 million men. Even more rare is scrotum agenesis. When penile replication is evident, so are other body part replications (so the news gets worse!). A man with Diphallia will also likely (a 69% chance) have two bladders, two livers and anuses. The risk of being born with spina bifida is very high (68% states this site). Infections from having two anuses and livers cause mortality rates to be quite high. Though little is known about Diphallia, it is thought that this disorder occurs in the 23rd to 25th day of gestation, when an injury, chemical stress, or malfunctioning gene hampers the penis to form correctly."
