There is no relationship between concentration, motility and vacuolated cells.

To determine whether there are differences between concentration and motility in the vacuolated spermatozoa of fertile donors, randomized men and infertile patients, semen samples were compared. Based on the percentages of concentration and motility, samples were divided into three groups: Group I, fertile donors, concentration >20×10/ml, motility >50%; Group II, patients, concentration <20×10/ml, motility <50%; Group III, randomized men, concentration >20×10/ml, motility >50%. In each group samples were assessed morphologically by the strict criteria of Kruger et al. The results showed that there was no difference between Group I and Group II, but there were differences between Group III and Group II, and Group III and Group I. We conclude that there is no relationship between concentration, motility and vacuolated cells. [ABSTRACT FROM AUTHOR]
