Abstract

Post-vasectomized azoospermic semen samples (N = 6) were analyzed for short tandem repeats (STR) on the Y-chromosome by using Y-PLEX™6 and the 310 Genetic Analyzer. We have observed a wide variation in the yield of extracted DNA from 12.5-1000 ng. This variation was attributed to the number of epithelial and/or white blood cells that are present in these azoospermic samples. DNA profiles of these vasectomized males were obtained for all six Y-STR loci, namely DYS393, DYS19, DYS389II, DYS390, DYS391, and DYS385 amplified by using the Y-PLEX™6.
