Case study one: a pregnant woman wants an abortion. Her husband doesn't. Should he have a say?
Case study two: a woman wants to become pregnant with frozen embryos. Her ex-husband opposes the decision. Should he have a say?
The answer, legally, is no in the abortion case, and in the case of frozen embryos, almost always yes.
It might seem paradoxical, but it is emblematic of the way technology is changing the landscape of human reproduction. And it is the kind of paradox that could get more attention with the nomination of Judge Samuel A. Alito Jr. to the Supreme Court.
