1 Conjoined twins occur in approximately one in 50,000 births, and the majority do not survive (they are stillborn).
Approximately 40 to 60 percent of conjoined twins arrive stillborn, and about 35 percent survive only one day. The overall survival rate of conjoined twins is somewhere between 5 percent and 25 percent. For some reason, female siblings seem to have a better shot at survival than their male counterparts.Although more male twins conjoin in the womb than female twins, females are three times as likely as males to be born alive.
