Should there be a national sperm bank registry?

The New York Times has been running an interesting series of op-ed articles about whether the U.S. should regulate sperm banks.

If Using a Known Donor to Inseminate, Don't Pick a Father

If you are going to use a sperm donor to get pregnant, picking someone who is already a dad seems like a good idea, right? After all, that person has a track record!
