Those up to date with controversies may have read about a prolific sperm donor in Europe. Over the years, he has been so generous with sperm donation to the extent that over 500 children are thought to have been born from his sperm.
And this is not only in Europe, but in other continents as well, owing to the availability of his sperm in international commercial sperm banks. He has now been banned from ever donating again. Enforcing this will be tricky as he has been known to disguise his ID to enable him to continue donating.
