How often do you have conjoined twins?

Conjoined twins are relatively rare, occurring in about 1 in 200,000 live births worldwide. The incidence of conjoined twins varies from country to country and is influenced by genetic, environmental, and reproductive factors. Conjoined twins can be classified according to the type of fusion, such as thoracopagus (connected at the chest), omphalopagus (connected at the abdomen), or pygopagus (connected at the buttocks). The prognosis for conjoined twins depends on the type and extent of the fusion, as well as the availability of medical care and resources. While some conjoined twins can be successfully separated and lead independent lives, others may face significant medical challenges or may not be able to be separated at all.
