Study Details

Study Description

Brief Summary

In assisted reproductive technology (ART), the diagnosis of male infertility has been conducted based on the assessment and analysis of sperm concentration, motility and morphology with the aim of obtaining the best quality of spermatozoa. Any type of damage present in sperm DNA can lead to ART failure. Sperm DNA fragmentation might be the most frequent cause of paternal DNA anomaly transmitted to offspring, and is found in a variable percentage of spermatozoa in subfertile and infertile men. Such DNA fragmentation is negatively correlated with semen quality and consequently, there is a need to develop sperm separation techniques that facilitate retrieval of as many spermatozoa with normal DNA integrity as possible from ejaculated semen.

Because of centrifugation steps associated to swim-up or density-gradient can induce sperm DNA fragmentation via reactive oxygen species (ROS), microfluidic sperm sorters are being used to isolate motile human spermatozoa based on fluid dynamics. It seems to be that using this separation method, spermatozoa do not undergo added physical stress from sources such as a centrifuge. Hence, this new technology has been proposed to minimize DNA damage. In this study, we aim to determine if microfluidic sorting improves the selection of the best functional and with lower DNA fragmentation spermatozoa when compared to magnetic activated cell sorting (MACS) in split semen samples, and increases clinical outcomes.
