Differential Spermatozoal Protein Expression Profiles in Men With Varicocele Compared to Control Subjects: Upregulation of Heat Shock Proteins 70 and 90 in Varicocele

These results suggest that increased expression of HSP 70 and HSP 90 may be associated with infertility in varicocele. Delineation of a potential subset of heat-related proteins specifically regulated in the context of varicocele may allow for the detailed elucidation of the mechanism underlying infertility in this condition.
