Relative contribution of glycosidases in the sperm soluble fraction to the total activities (100%) measured in the ejaculate of fertile controls and oligoasthenoteratozoospermic patients. β-glucur (β-glucuronidase), α-mann (α-mannosidase), α-gluc (α-glucosidase), α-galact (α-galactosidase), β-galact (β-galactosidase) and β-NAG (β-N-acetylglucosaminidase). Bars represent means ± SD. ∗P<.05, vs. fertile controls. †P<.01, vs. fertile controls.

3. Figure 2
β-galactosidase and β-N-acetylglucosaminidase activities in the soluble fraction of spermatozoa in fertile controls, oligoasthenoteratozoospermic and azoospermic patients. β-galactosidase activity (upper panel) is expressed in mU/mg of protein (left) or mU/ejaculate (right). β-N-acetylglucosaminidase activity (lower panel) is expressed in mU/mg of protein (left) or mU/ejaculate (right). Bars represent means ± SD. ∗P<.05, vs. fertile controls. †P<.01, vs. fertile controls.
