BioEdge: Putting a price on American sperm

BioEdge: Putting a price on American sperm

Putting a price on American sperm

A number of Western countries have banned sperm donor anonymity, but not the United States. However, many people insist that children have a right to know who their biological father is, putting the sperm donor industry under pressure to defend anonymity.

What if the US adopted the UK model, under which children could find their fathers once they turn 18? An immediate result would be a decrease in the number of donors, as most sperm donors do not want the responsibilities and commitment of fatherhood – especially if it involves money.

In an article in Journal of Law and the Biosciences Professor Glenn Cohen, of Harvard Law School, and representatives of US IVF clinics have calculated the market impact of removing anonymity in the US. After Sweden removed anonymity in 1985, the number of annual new donors dropped from 200 to 30. However, in the US Cohen and his co-authors say that a large number of donors would refuse to donate and that market forces would force the price up:

... 28 per cent of sperm donors at a large US sperm bank would refuse to participate if anonymity is prohibited. Among those who would continue to participate, the typical donor would demand a premium of anywhere from $40 to $102 over what they are currently paid. Our findings suggest that such a change would have a significant, but perhaps not insurmountable, effect on the supply of sperm in the USA should the law change.


Winston Churchill was once voted the “greatest Briton of all time” in a BBC poll, edging out Isambard Kingdom Brunel (who?), Lady Diana, Shakespeare and John Lennon. Now, in addition to his gifts as a statesman and politician, orator and historian (and artist), we have been reminded that he helped to popularise science as well.
As reported in Nature, an historian has discovered an 11-page manuscript which Churchill penned in 1939 but never published, speculating about life on other planets. It turns out that the great man was deeply interested in modern science and followed developments keenly. Gazing at the gathering storm, he wrote pessimistically:
“I, for one, am not so immensely impressed by the success we are making of our civilization here that I am prepared to think we are the only spot in this immense universe which contains living, thinking creatures, or that we are the highest type of mental and physical development which has ever appeared in the vast compass of space and time.”
But despite the reminder that Churchill was a fan of science, it’s also good to remember that he believed that there were moral limits to science. In one of his most famous speeches, he foresaw dark days for the world if Germany were to win the War:
If we can stand up to [Hitler], all Europe may be free and the life of the world may move forward into broad, sunlit uplands. But if we fail, then the whole world ... will sink into the abyss of a new Dark Age made more sinister, and perhaps more protracted, by the lights of perverted science. Let us therefore brace ourselves to our duties, and so bear ourselves that, if the British Empire and its Commonwealth last for a thousand years, men will still say, "This was their finest hour."
Science, so Churchill believed, was fascinating, but not good in itself. It had to be governed by morality, lest it become “perverted”. It’s not a bad reminder for us, three generations on, as we enter an era of genetic engineering.
