This study aims to assess the effect of age of the male partner and the reproductive ability of sperm prepared via sperm selection devices (Zymot) compared to routine embryologist selected sperm after density gradient centrifugation (DGC) preparation for intracytoplasmic sperm injection (ICSI) in patients undergoing in vitro fertilization treatment (IVF) of their infertility.
In this study, we aim to determine the clinical utility of the Zymot sperm selection methodology for ICSI, while also accounting for paternal age. This study will be a prospective, split cohort, randomized, control trial comparing the routine standard of DGC sperm preparation for ICSI versus sperm prepared via Zymot for ICSI. Embryology parameters, ploidy status, DNA fragmentation and clinical pregnancy outcomes will be assessed.

An aliquot of 850ul will be used for the Zymot sperm selection device. The sperm processing via Zymot will be per manufacturer's guidelines
5ul of the ejaculated sample will be assessed for DGC via Makler assessment. If the sample for DGC is adequate per lab standard operating procedures, then routine DGC sperm preparation and embryologist sperm selection for the ICSI procedure will occur.
