Semen quality was assessed and lipid spectrum of seminal plasma was determined in 42 stallions of different breeds aged from 5 to 16 years (average 9.8±5.4 years). The concentration of total cholesterol, triglycerides, high density lipoproteins and low-density lipoproteins were determined in semen plasma. We found a negative correlation between the concentration of low- and high-density lipoproteins and progressive sperm motility in both fresh (p<0.05) and thawed (p<0.05) semen. We also found a negative correlation between the concentration of low-density lipoproteins in sperm plasma with total sperm motility in fresh (p<0.05) and frozen (p<0.01) semen, and the concentration of high-density lipoproteins in sperm plasma with total sperm motility in fresh and frozen semen (p<0.05). We found a significant negative correlation between ejaculate volume and concentration of triglycerides (p<0.05), cholesterol (p<0.01) and high-density lipoproteins (p<0.05). There was a positive correlation between sperm concentration and triglycerides (p<0.05), cholesterol (p<0.001) and high-density lipoprotein (p<0.01) content.
