Randomized Non-inferiority Within-Patient Trial of Density Gradient Processing of Sequential Ejaculates Versus Centrifugation-free Sperm Separation Device for ICSI in Men With Elevated Sperm DNA Fragmentation.
Randomized Non-inferiority Within-Patient Trial of Density Gradient Processing of Sequential Ejaculates Versus Centrifugation-free Sperm Separation Device for ICSI in Men With Elevated Sperm DNA Fragmentation.
Elevated SDF can adversely impact fertilization, embryo development, and pregnancy outcomes in IVF-ICSI cycles. Two pragmatic strategies aim to reduce SDF on the day of ICSI: (i) obtaining a second ejaculate shortly after the first to reduce oxidative damage and transit time; and (ii) selecting sperm via centrifugation-free sperm separation device, which enriches for motile sperm with intact DNA. There are limited direct comparisons between these strategies; this study addresses that gap.
Inclusion Criteria:
• Elevated SDF defined as DFI >20 %measured by the sperm chromatin dispersion (SCD) test performed in a participating center's andrology laboratory, using a harmonized protocol under standardized conditions after 2-3 days of ejaculatory abstinence, and within 90 days (≤3 months) prior to enrollment.
