Concerning morphological parameters, only the
percentage of abnormal spermatozoa was statistically
different between male A and males N (33.60 4.12%
vs. 18.48 1.52%, for A and N respectively, Table 3).
Male A produced semen of lower sperm concentration
than the males N (66.55 22.75 106 sperm/ml vs.
171.65 9.90 106 sperm/ml, for A and N males
