title: Correlation of lactate dehydrogenase isoenzyme C4 activity with the count and motility of human spermatozoa.
abstract: The activity of lactate dehydrogenase isoenzyme C4 was determined on 90 human semen samples. The correlation between the isoenzyme activity and sperm count and motility was good (r = 0.74 for values of U/ml semen against sperm count).
