433 (16.1%) samples had a sperm viability gay hookup apps for android of ? 58%, the lower limit of normal according to the 2010 WHO laboratory manual guidelines . For these samples, the mean DNA fragmentation was ± %. For the 2262 samples with viability > 58%, the mean DNA fragmentation was ± % (p < 0.001).

001) was seen between sperm viability and DNA fragmentation, with Pearson’s product-moment correlation coefficient r = -0.83 (Figure 1), t = -, df = 3047, p < 0.001 and a 95% confidence interval of -0.836 to -0.814. If viability was very high (? 80%, n = 1104) then DNA fragmentation was consistently < 30% (100% sensitivity to predict DNA fragmentation < 30%). If viability was ? 75% (n = 1736), then the DNA fragmentation was < 30% for 95% of the patients (Table 2). For samples with very low viability (viability ? 35%, n = 91) then DFI was always ? 30%. If viability was ? 50% then DNA fragmentation was ? 30% for 95% of the samples (n = 310). The results of the semen analysis testing with respect to vitality and DFI are seen in Tables 3 and 4.

Elevated sperm DNA fragmentation rates have been positively correlated with impaired fertility, including longer times to natural conception , impaired embryo cleavage , impaired implantation rates , higher miscarriage rates , and increased risk of pregnancy loss after both in vitro fertilization and intracytoplasmic sperm injection . Using the sperm chromosome structure assay, couples with a sperm DNA fragmentation of < 40% have been shown to have an odds ratio of 10? greater probability of pregnancy via natural intercourse than those with DNA fragmentation > 40% . Likewise, intrauterine insemination patients have been shown to be 8.7? more likely to have a live birth if the DNA fragmentation is ? 27% . Finally, a DNA fragmentation rate of ? 30% has been associated with increased spontaneous abortion rates . The first of these was a meta-analysis of four studies, with a total of 1962 men, found that men with a DNA fragmentation < 30% were more likely to achieve a pregnancy or live birth either spontaneously or via intrauterine insemination (p = 0.0001) [6-8].
