Of the couples who have problems with infertility, about 40% are due to problems with sperm. The problems could be due to the number of sperm present, how active they are or what shape they are. According to the World Health Organisation, a man is at risk of infertility if his sperm count is less than 20 million per ml. of semen.

The male infertility test kit supplied by SelfDiagnosis contains two tests and will identify if sperm is less than this recommended level.
