Swim-up procedure selects spermatozoa with longer telomere length.
Telomere length and sperm DNA fragmentation were determined in sperm samples from 27 patients, using a quantitative PCR (Q-PCR) assay and the Sperm Chromatin Dispersion (SCD) test, respectively. Comparisons of the samples before and after swim-up processing demonstrated that this procedure selects a sperm population with longer average telomere size and lower frequency of sperm cells with fragmented DNA.
