UK National Sperm Bank

(Birmingham, England) Britain's national sperm bank has few donors, only nine.

It is now planning a recruitment drive, with chief executive Laura Witjens saying that appealing to male pride may be an effective way to boost donations.

She has suggested a new campaign featuring a cartoon superhero, echoing a successful strategy in Denmark.

A change in UK law in 2005, removing anonymity for sperm donors, is thought to have led to a drop in volunteers.

Children born from donated sperm will be told the name of their father at age 18.
