Bifid penis

A bifid penis, also called a double penis, is a rare congenital defect in which two genital tubercles develop during formation of the body. Because it arises before birth it belongs among the congenital malformations rather than acquired disease. The same article also notes that many species of male marsupials have a naturally bifurcated penis, with left and right prongs, so the split form is a normal feature in those animals while it is an abnormality in humans. This record summarises what the reference source says about the condition and is not medical advice.
