Capacitacion and acrosomal reaction of epididymal bull spermatozoa in vitro: biochemical and biotechnological aspects

D. D. Ostapiv

Intensity of oxidizing processes in epididymal bull spermatozoa for the actions of factors of capacitacion in vitro has been investigated. It is discovered that gametes in the presence of follicular fluid and heparin show hyperactive motility and is characterized by the higher values of oxygen uptake and reduction activity and increase of glucose-6-phosfate dehydrogenase and succinate dehydrogenase activity. The increase of the cianid resistence breathing specifies on stimulation by the factors of capacitacion oxidizing of structures membranes of spermatozoa, that by the provides the display of acrosomal reaction.
