摘      要：Sperm selection is an essential component of all assisted reproductive treatments(ARTs)and is by far the most neglected step in the ART workflow in regard to technological *** sperm selection methodologies typically produce a higher total number of sperm with variable motilities,morphologies,and levels of DNA ***-standard techniques,including density gradient centrifugation(DGC)and swim-up(SU),have been shown to induce DNA fragmentation through introducing reactive oxygen species(ROS)during ***,we demonstrate a 3D printed,biologically inspired microfluidic sperm selection device(MSSP)that utilizes multiple methods to simulate a sperms journey toward *** are first selected based on their motility and boundary-following behavior and then on their expression of apoptotic markers,yielding over 68%more motile sperm than that of previously reported methods with a lower incidence of DNA fragmentation and *** from the MsSP also demonstrated higher motile sperm recovery after cryopreservation than that of sU or neat *** were conducted side-by-side against conventional SU methods using human semen(n=33)and showed over an 85%improvement in DNA integrity with an average 90%reduction in sperm *** results that the platform is easy-to-use for sperm selection and mimics the biological function of the female reproductive tract during conception.
