Evaluating the Utility of Implementing Microfluids for Sperm Preparation Compared to Conventional Method of Density Gradient Centrifugation in a PGT-A Program: a Sibling Oocyte Study

The FERTILE PLUS™ method is a standardized method with an easy-to-follow protocol that is far less dependent on the skill or experience of the embryologist than other methods, such as density gradients. The FERTILE PLUS™ (850 µL) Sperm Sorting Chip is a single-use, flow-free, dual chambered, microfluidic-based sperm sorting device. FERTILE PLUS™ was previously known as Zymot, prior to a name change by the manufacturer. The lower chamber contains a sample inlet and fluid channel separated from the upper collection chamber by a microporous membrane with 8-μm pores, demonstrated as the optimal size for selection of sperm with higher motility and normal morphology \[18\].
