ABSTRACT
<p><b>OBJECTIVE</b>Sperm chromatin structure assay (SCSA), as a clinically practical technique for the analysis of DNA damage, is rarely reported in China. This study focuses on the correlation of DNA damage with the pregnancy rate of intrauterine insemination (IUI).</p><p><b>METHODS</b>We performed semen analysis for 482 couples undergoing IUI, calculated the DNA fragmentation index (DFI) by SCSA, and observed the relationship between DFI and the pregnancy rate of IUI.</p><p><b>RESULTS</b>Clinical pregnancy was achieved in 5 (5.26%) of the 95 cases with DFI > 25%, and in 59 (15.25%) of the 387 cases with DFI < or = 25%. Those with sperm DFI >25% had significantly lower rates of biochemical pregnancy and clinical pregnancy than those with DFI < or = 25% (OR 0.37, 95% CI 0.14 - 0.96 and OR 0.38, 95% CI 0.16 - 0.97). No significant differences were found in the DFI of 54 cases between the first and the second cycle ([15.05 +/- 7.98]% vs [17.25 +/- 12.18]%, P > 0.05). Sperm DFI was significantly negatively correlated with sperm concentration, sperm motility and total progressively motile sperm count (P < 0.01).</p><p><b>CONCLUSION</b>The pregnancy rate of IUI is significantly lower in couples with DFI >25% than in those with DFI < or = 25%. Sperm DFI obtained from SCSA is partly correlated with sperm concentration and motility, and it is a robust predictor of the IUI outcome.</p>
