The delivery would probably be the most dangerous part of this hypothetical process, because there would be a high risk of hemorrhaging. During pregnancy, the placenta extends villi, hairlike projections containing blood vessels, into the surrounding tissues to establish a blood supply for the baby. Unlike the uterus, the abdomen is not designed to separate from the placenta during delivery. The placenta would become so bonded to the man's body that it might be impossible to surgically remove it without also removing parts of abdominal organs, such as the bowels. The likely end product: a gaping wound in the abdomen and heavy, uncontrolled bleeding, says Gillian Lockwood, medical director of Midland Fertility Services, a leading British fertility clinic.
