Sperm Nuclear DNA Damage in the Human
The male partner is now recognized as the single most common contributor to a couple’s reason for infertility, with sperm defects accounting for around 30–50% of cases presenting to infertility clinics (Hull, 1992). A standard semen analysis, in particular the assessment of sperm concentration and motility, should therefore always be viewed as a mandatory test for inclusion in the investigation of the infertile couple (WHO, 1992; WHO,1999). A semen analysis, however, only helps to provide broad diagnostic categories.
