There has been considerable discussion about the impact artificial womb technology may have on debates in reproductive ethics. Much of it has focused on abortion. Some ethicists have also proposed, however, that artificial wombs will lead to more embryo adoption, and, in doing so, that they will eliminate an alleged moral tension between opposing most abortions based on a full moral status view of fetuses/embryos but not opposing the use of surplus embryos in fertility medicine. This article evaluates this argument, (...) what I will call the artificial womb argument. It defends two main claims. First, artificial womb technology is unlikely to lead to embryo adoption on the scale needed to resolve the moral tension between opposing abortion but tolerating the use of surplus embryos in what has been termed “parent-friendly” in vitro fertilization (IVF). Second, artificial womb technology is more likely to increase the use of surplus embryos. The artificial womb argument backfires, therefore, on abortion opponents. Far from mitigating the moral tensions between opposing abortion but tolerating parent-friendly IVF, artificial womb technology is more likely to exacerbate these tensions. (shrink)
