We postulated that in some men, the sperm viability assay could predict the sperm DNA fragmentation rates. This in turn could reduce the need for sperm DNA fragmentation assay testing, simplifying the infertility investigation and saving money for infertile couples. All men having semen analyses with both viability and DNA fragmentation testing were identified via a prospectively collected database.
