title: Relationship between spermatozoon movement velocity and expression of testicular isoform of angiotensin-converting enzyme on their surface.
abstract: The expression of testicular isoform of angiotensin-converting enzyme on the surface of human spermatozoa was evaluated by flow cytometry with monoclonal antibodies to epitopes of C-terminal domain of human angiotensin-converting enzyme and the mean path, mean curvilinear and straight-line velocities were determined by computer analysis of spermatozoon movement. A positive correlation between the expression of testicular isoform of angiotensin-converting enzyme on the cell surface and spermatozoon movement velocity was revealed.
