Contents
 The aim of this study was to evaluate the effect of the
inclusion of divalent ion chelating agent EGTA (ethylene
glycol tetraacetic acid) in the freezing extender on
quality of cryopreserved bull sperm. The freezing
extender (egg yolk Tris glycerol) was supplemented with
0 (non-supplemented), 1, 5, 10 and 15 mM EGTA. Bull
sperm EGTA improved post thaw sperm quality but in
different parameters according to the concentration of
EGTA, 5 mM improved the acrosomal state and 1 mM the
motility. Our results suggest the EGTA supplementation
in the freezing extender of bull sperm might improve the
post-thawing sperm quality
