Alpha‐glucosidase activity and sperm motility

Summary We correlated the activity of alpha‐glucosidase in seminal plasma with the motility and differential motility of sperm. Significant positive correlations were found between the alpha‐glucosidase activity and both motility and the percentage sperm with good forward progression. This supports the use of alpha‐glucosidase in semen as a marker of epididymal function and specifically of the development of motility.
