Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

In assisted reproductive technology (ART) semen needs to be processed. Commonly used methods rely on physical properties of the spermatozoa, such as the swim-up methods and density gradient centrifugation. It is now known that current processing of spermatozoa does not prevent the admixture of spermatozoa with damaged genetic material. The latter have a negative impact on the outcome of ART. The investigators developed a new method for the processing of spermatozoa with intact genetic material based on flow cytometry and sorting (FACS) and on staining using a deye, YoPro. The investigators aim at examining the effect of this novel method of sperm sorting on the outcome of ART.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

YoPro and FACS

Spermatozoa to be used for ICSI will be stained with the YoPro Dye and then be sorted with FACS to select non-YoPro stained spermatozoa, known to have significantly less fragmented DNA.
