A Tennessee doctor is practicing reproductive medicine aligned with his Christian faith. Dr. John Gordon’s Knoxville clinic limits how many embryos it creates and does not discard viable embryos, genetically test them or donate them to science. His clinic draws patients nationwide who are concerned over the moral issues that surround in vitro fertilization. The IVF debate has been growing since court decisions ended federal abortion rights nationally and designated embryos as children in Alabama. Some Christians and anti-abortion activists who believe IVF is unethical have criticized Gordon. But he says he's still committed to reconciling his work with his faith.
