Abstract
Summary
Electrophoretic examination of the plasmas from specimens of human semen which were either (1) abnormally viscous or in which (2) the sperm were either poorly motile or non-motile, or which (3) contained no sperm revealed no definitely significant deviation in protein components from normal specimens. Components P1 (proteose), P2 and P3 (globulins) were present in all these specimens as they are in normal ones. Component P2a (globulin), described in an earlier report as being present in occasional normal specimens, was found in some of the abnormal ones also. Normal specimens contain either P4 or P5 (glycoprotein) or both. Component P5 was present in all the abnormal specimens. The absence of P4 from all but one of these is noteworthy, but the varied nature of the abnormality makes interpretation difficult.§
