A bifid penis is a rare congenital defect involving a penis that is split or duplicated into two penises. It can be considered a form of diphallia. Based on the presence of one or two corpora cavernosa, diphallia is classified into two major groups: bifid penis (in which only one corpora cavernosa is present, but split) or true diphallia (in which a duplicate, secondary corpora cavernosa is present). A bifid penis may be partially split or fully split down the entire length of the penis. In Animals Many species of male marsupials have a naturally bifurcated penis, with left and right prongs that they insert into multiple vaginal canals simultaneously.
