How does sperm count predicts differential in survival for an Andrologic Clinical Cohort?

Background: There are few studies Eisenberg et al. (2014), Jensen et al. (2009) and our own group (Gross et al. 2006) showing that men with impaired semen quality parameters have a lower survival than men with normal parameters.
