UroPrecision, EarlyView.Abstract Background Viral infections have been identified as potential disruptors of male reproductive health. This study aimed to investigate the prevalence of human cytomegalovirus (HCMV), human herpesvirus 6 (HHV‐6), and herpes simplex virus types 1 and 2 (HSV‐1/2) DNA in semen samples from fertile and infertile men within the potential impact of ...

Spermatid head counts of C57BL/6J and Trail−/− mice at PND 56.
, 2014 The total number of mature spermatid heads were counted from 11 C57BL/6J and 8 Trail−/− mice at PND 56. Trail−/− mice have significantly lower spermatid head counts than C57BL/6J mice.
