Reports claim that as many as one in five healthy young men between the ages of 18 and 25 produce abnormal sperm counts.
Only 5 to 15 per cent of their sperm is good enough to be classed as 'normal' under World Health organisation rules - proving that infertility is not just a female problem. Indeed, among those experiencing difficulty with conception, a male fertility problem is considered important in about 40 per cent of couples.
