Abstract Purpose:In order to study the unknoun reason male sterility patient′s sperm core DNA quantity and the circumstanlce change about the sperm form.Methods:The semen of 50 normal fertility′s male was compared with 35 unknown reason of sterility patient′s,analysing sperm core DNA integral optical density,average grey matter,the quantity and form about sperm′s area,core′s length,core′s width perimeter circumference tail′s length,etc.Results:Sterility patient′s sperm core DNA integral optical density had a clear reduction (P<0.01);average grey matter had a clear increase (P<0.01),area core′s length core′s width perimeter circumference and tail′s length contrast with fertilitys male′s had no significant difference (P>0.05).Conclusions:The unknoun reason male sterility patient′s sperm core DNA integral optical density had a clear reduction.
