America's Most Renewable Resource?

I have noted previously a New York Times article about some of the ethical questions being raised regarding sperm donors and genetically transmitted diseases and numerous half-siblings.  Now Time has an article about how sperm sales are big business and the U.S. is in the forefront due to the fact that donors can maintain anonymity.  While addressing the same issues the New York Times raised, the Time article also discusses new potential problems, such as estate claims, and why American donors are in such high demand.

The article is available in the April 16, 2012 print edition, and online to Time subscribers.
