Did you realise there are just over 200 registered sperm donors in the UK, despite a male population of more than 22 million men? I wrote about this crisis last August after Bourn Hall Clinic turned to a donor bank in Denmark to make up its desperate shortfall.

The crisis is a result of new laws introduced in April 2005 which removed anonymity from sperm donors. I heard a report on radio recently about sperm donors  being tracked by children they had biologically “fathered” this way.

For only £163, and using genealogy and DBA databases on the internet, it is possible to track down anonymous donors, as this teenage boy did. It is naturally a very strong deterrent for would-be donors who fear financial claims will be made against them, as well as paternal responsibilities.

Comedian Danny Robins  hilariously raised the profile about this dilemma by travelling around the country searching for donors with his mobile donation centre (a converted polling booth). His visits included Westminster where he invited Labour MPs who changed the law to lead the way (John Prescott was thankfully ruled out for being too old) for The Great Sperm Crisis to be screened on  BBC Three  tomorrow night.

The law was introduced to protect the rights of the unborn child, but is ironically producing fewer children as a result, and untold misery for childless women.  Fertility experts estimate that we need 500-600 donors for the current demand to be met.

Any offers?
