title: Adenosine 5 triphosphate (ATP) content and acrosin activity in polyzoospermic subjects.
abstract: The aim of this paper was to measure the concentration of spermatic ATP and acrosin in a group of patients with polyzoospermia, and to compare these values with those found in a group of normozoospermic men. The general characteristics of the semen, the ATP and the acrosin, were measured in a group of 46 men with polyzoospermia, who consulted in our clinic for sterility. The results were compared with those of 50 normozoospermic men in the control group. Statistically, no significant difference was found between the volume, motility and morphology of the samples in both groups; however, the concentration of spermatic ATP and acrosin decreased significantly in a group of polyzoospermic patients. This could be due to a functional defect of the spermatozoa in this group of patients.
