>>The number of British male donors has nearly halved from 417 in 2005, after children were allowed to contact their donor father when they reached the age of 18.<<
Now that I got my quip out of the way, if you look at this, you see a perfect example of the Law of Unintended Consequences.
For the moment, the donor remains 100% anonymous in the US, but who knows what will happen when the latest generation start asking why they have an extra pinky or eye or whatever.
This is the steep part of the slippery slope of screwing with nature.
You beat me to it. I agree, except I can’t for the life of me think the powers that be couldnt figure out that was going to happen.
