Sperm preparation with SpermGrad show positive effect on average telomere length, sperm motility and DNA fragmentation
Yang Q, et al, found significant correlations between sperm telomere length and the quality of early embryonic development. Density gradient centrifugation using SpermGrad (Vitrolife) enrich for sperm with high mobility and low DNA fragmentation and is the preferred technique for selection of sperm with longer telomeres.
