Is there a moral way to use in-vitro fertilization?

A couple of weeks ago I critiqued Ken Neal's op-ed attack on the pro-life stance on federal funding for embryonic stem cell research. I acknowledged that he made a valid point about in-vitro fertilization (IVF) and the creation of "surplus" embryos that are routinely frozen or destroyed. If those embryos are human life, as I believe, then we have to question the practice of IVF on moral grounds. The ends -- having a baby -- can't justify the means if the means involve destroying human life.

Today, Joe Carter of Evangelical Outpost examines the ethics of IVF and other means of dealing with infertility from a Christian perspective. He links to an article on reproductive technologies by Daniel McConchie of the Center for Bioethics and Human Dignity. McConchie suggests that by taking certain precautions IVF can be used in a way that does not involve destroying embryos or exposing them to a greater level of risk than would be encountered in nature.

There's a vigorous discussion in the comments to Joe Carter's post, and rather than try to duplicate that here, I'm going to turn off comments on this entry. If you have a comment, please post it over there.
