A new device that checks a man’s sperm count at home is soon to go on sale in U.K. The developer, Dr John Herr, of the University of Virginia in Charlottesville, said it would suit couples who had tried for pregnancy for a few months but weren’t ready to seek professional help. The SpermCheck fertility test will retail for about $45 and is said to be 96 percent accurate. Sperm counts of 20 million per millilitre of semen and above are considered normal. The test will tell if a man’s sperm count meets this level. If both strips are negative the man is likely to be infertile.  The test works by detecting the antigen (SP-10) found on the surface of the head of a sperm cell. - Daily Mail
