Conjoined twins have invited a lot of curiosity over the years, medical and otherwise, around the world. Various parents have exhibited their children, thus born, inviting a certain fame and even making a living off it, at times.
This of course is true for those conjoined twins who survived. The overall survival rate of conjoined twins is somewhere between 5 percent and 25 percent.
Conjoined twins develop from a single fertilised egg and are therefore always identical and of the same sex.
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. Approximately 70% of all conjoined twins are girls, according to the University of Maryland Medical Center.
Read here about some conjoined twins who are still alive:
Siamese twins: The most famous pair of conjoined twins was Chang and Eng Bunker, Thai brothers born in Siam, now Thailand. They travelled with P.T. Barnum's circus for many years and were known as the Siamese Twins. Due to the brothers' fame and the rarity of the condition, the term 'Siamese twins' came to be used as a synonym for conjoined twins.
