The idea of an effective sperm bank has appealed to eugenically minded individuals for a good few centuries. Such arrangements have only recently become practically feasible. The first two sperm banks set up in Lowa City and Tokyo, which both began “life for life” in 1964.

The first sperm-bank child was born in the U.S. in 1953 and in the words of Gerald Leach, was “perfectly normal”. Since then the numbers have swelled, with the sperm storage period being gradually lengthened. It seems that little ecological or eugenic thought has gone into this subject.
