The U.S. has become the gold standard of sperm, but it is not because of any reproductive exceptionalism.

It turns out that the FDA's strict screening process and the multi-ethnic makeup of the American population have made U.S. "the gold standard of sperm."

Time magazine has a revealing report on why America is dominating the sperm market.

As with any good, it all comes down to quality control and variety of the product, says the Time senior editor Jeffrey Kluger.

There is no shortage of tall, smart men willing to donate sperm in the U.S. Height requirement cutoff is 5' 9'' and PhD degree holders are compensated up to $500 per deposit.

While donors sign waivers of parental rights, potential children can seek child support through the courts. However, American sperm does not grant U.S. citizenship to foreign-born children.
