The content of pathological forms of spermatozoids in fresh sperm of boars fluctuated (3-7%, on the average 4,4%). After dilution and storages of sperm within three days the percent of abnormal cages consistently increased. In the third day the increase was fivefold (22,4%). The increase occurred basically at the expense of increase of secondary and tertiary anomalies. Spermatozoids with damages of acrosomes among mobile cells in not diluted sperm was 5,1%, in the diluted sperm within the first days of storage - 8,3%, and in 2-3 days their percent increased in 13 and 17,6 accordingly. Capacitated spermatozoids in the investigated ejaculates came to light in insignificant quantity in the first day, and then their percent increased in 6,8 and 10%. Correlation communication of percent spermatozoids with damages of acrosomes in not diluted sperm with impregnating ability was absent (r=0,07), and in the course of storage became uncharacteristic. Initial activity of spermatozoids made essential impact on their stability to morphological changes in storage process. Return correlation communication of activity with percent of pathological forms increased in process of increase in a period of sperm storage. The correlation factor in the third days has made 0,70 (Р 0,05). With impregnating ability of sperm initial of spermatozoid activity, also as well as ejaculate volume had positive, but low (P 0,05) correlation communication
