Supporters of surrogacy tend to believe it is a win-win situation. Someone who desperately wants a child is given the opportunity to be a parent by someone who can have a baby, and is willing to do so either for money or out of benevolence (such as a sister acting as a surrogate for a sibling.) The truth is that the majority of surrogacy cases are ones where money changes hands. And when money changes hands, and the very lives of humans are at stake, things going badly awry.
