Enzyme levels in semen of men with different types of azoospermia

Abstract

The levels of eight enzymes have been measured in the semen of 15 azoospermic subjects. The results indicate that the values of the enzymes Creatine kinase, and Alanine aminotransferase, just as the Aspartate aminotransferase/Alanine aminotransferase ratio are significantly different between excretory and secretory azoospermics. The enzymes Aspartate aminotransferase, Lactate dehydrogenase, alpha-Hydroxybutyrate dehydrogenase, Gammaglutamyl transferase, Acid phosphatase, and Alkaline phosphatase and the alpha-Hydroxybutyrate dehydrogenase/Lactate dehydrogenase ratio have values which do not differ significantly between the two groups of azoospermic men.
