Mr. Jiri M. has a peculiar hobby. Few years ago he put on the internet an advert ‘I make only beautiful daughters.’ Since then, beside six daughters he has with his wife, he has begotten around twenty daughters. Mr. Jiri is not the only man like this. In Holland lives the 48 years old Mitch., who does the same in grand style, as there is no wife to slow him down – with 106 children he got nicknamed ‘the most virile man in Europe’ by the media. The true insemination superpower is Denmark, where whole system stands and falls with anonymity. But even that has its pitfalls, and not only in the form of disease from an unknown donor as the infamous case of ‘Donor 7042’. What is the responsible way to create the future generations?
