[Sperm DNA as a parameter of male infertility].
Andrological examination is essential to any sterile marriage. Percentually normal DNA levels were recorded from 61.2 per cent of 170 male probands and from 36.5 per cent of 59 fertile men. Fertility rates were found to drop by half, when spermatozoan density fell below 20 million/ml and relative DNA content below 80 per cent. A relationship between DNA level and oligozoospermia could not be statistically secured for the low number of probands.
