World's Oldest Conjoined Twins, Ronnie & Donnie Galyon
Ronnie and Donnie Galyon are the world's oldest living set of conjoined twins and also the world's only adult male conjoined twins. Born in Dayton, Ohio on October 28, 1951, the brothers, joined from the sternum to the groin, were delivered vaginally. According to Ward Hall, the twins' mother rejected them when they were born, leaving them to be raised by their father, Wesley, and later stepmother Mary. For the first two years of their lives, the twins were in and out of hospitals while doctors attempted to determine whether or not the twins could be separated. Because they share a single set of male organs, doctors decided that it was best not to separate them. They learned to walk at the age of 29 months.
