الملخص EN

The semen was collected from five adult Iraqi black local bucks by the artificial vagina and using estrous induced doe the semen was diluted with egg yolk 10% extender and frozen by liquid nitrogen for three months, macroscopic and microscopic evaluation were done after collection, dilution and thawing, three media(TCM-199, DMEM and SOF)were used to see the their effect on activation of spermatozoa.

The results showed that TCM-199 media presented higher significance in sperm motility, progressive motility compared with DMEM and SOF media.

There was a great decrease in the concentration of spermatozoa after activation using these media which didn’t differ significantly among them and they were higher significantly compared with control in normal morphology.
