Figure 1. Split semen preparations. Semen samples, n=25, were prepared using ZyMōt™ (0.85mL) or density gradient centrifugation (DGC). A. Raw semen sample values, showing presence of progressive motile sperm, non-progressive motile sperm and immotile sperm. B. After sperm selection using ZyMōt™, enrichment of progressive sperms. C. Post sperm selection using DGC, enrichment of progressive sperm. D. Absolute number of progressive sperm after sperm selection for ZyMōt™ and DGC, higher number of progressive sperm after DGC. E. Per sample comparison of percentage of progressive sperm after sperm selection. Preparation with ZyMōt™ resulted in higher fraction of progressive sperms compared to DGC for all samples.
