How are identical twins born?
Approximately two-thirds of twin births in the United States are done by cesarean, and one-third are done vaginally. This is almost the opposite for singleton births. The statistics include those births where one twin is born vaginally, but his or her twin is born by cesarean. It is not uncommon for the second twin to decide to stretch out and enjoy all that room once his or her twin has left, making a vaginal birth impossible. Health complications of both the mother and second twin may also arise after the birth of the first twin to make a caesarean necessary.
