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. Posted on forum: The anonymous man spent six hours answering questions after he posted this photograph on Reddit of his penile duplication earlier this year. The condition affects around one in every six million boys in the U.
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. When the condition is severe, these defects are insurmountable. This change in expression is brought upon by mutations in the genes or environmental factors.
Diphallia , penile duplication PD , diphallic terata , or diphallasparatus , is an extremely rare developmental abnormality in which a male 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. The occurrence is rare, at once in every five to six million live births,  with 1 in 5.
