Impact of microfluid sperm sorting on embryo ploidy rates in couples with high sperm dna fragmentation?

Increased sperm DNA fragmentation (SDF) is one of the leading causes of male infertility. Conventional methods for sperm preparation have induced questioning of sperm recovery rates. The microfluidic sperm sorting (MSS) technique selects highly motile sperm with lower levels of SDF compared to density-gradient centrifugation (DGC) technique. This study aimed to compare MSS to DGC technique in couples with repeated implantation failure (RIF) and high SDF referred to a PGT-A (preimplantation genetic testing for aneuploidies) cycle.
