Let's Give Ourselves a Big Hand

Here's an economic success story I didn't see coming:

Sperm has become a vigorous (ahem), multi-million dollar global industry. The sperm trade is growing ever larger and ever more international, with more and more kids being born via unknown fathers on distant continents. By some estimates, the United States is the world’s largest exporter of sperm, sending vials to dozens of countries every year.

It's one of the little-known spin-offs of our vibrant porn industry.
