['Seminal plasma was investigated as a contributor to the poor sperm motility of spinal cord injured men.', 'Seminal plasma of spinal cord injured men was mixed with sperm of normal men and vice versa. Sperm motility was analyzed at 5 and 60 minutes after mixing.', 'At 5 (but not 60) minutes seminal plasma from spinal cord injured men inhibited motility of sperm from normal men. Concomitantly, seminal plasma from normal men improved motility of sperm from spinal cord injured men.'] Does seminal plasma of spinal cord injured men inhibit sperm motility of normal men?
