Sialic acid levels were determined in spermatozoa and seminal plasma of 47 semen samples divided into two groups according to sperm counts. Group 1, up to 40 x 10(6) sperm/ml seminal fluid and group 2, above 40 x 10(6) sperm/ml seminal fluid. The content of sialic acid in spermatozoa ranged from 4.4-28.1 micrograms/10(8) spermatozoa and from 70-95 mg/100 ml seminal plasma. Sialic acid was significantly higher in sperm and lower in seminal plasma of group 1 as compared to group 2. The lower content of sialic acid in seminal plasma might have a deteriorating effect on structural integrity of sperm.
