title: [Relation between aspartate aminotransferase (AST) activity in the seminal fluid and indicators of boar ejaculate quality].
abstract: In a set of 154, and/or 260 ejaculates, collected from 72 boars, a relationship was studied between the activity of aspartate aminotransferase (AST) in seminal plasma and sperm concentration, and/or percent occurrence of morphologically abnormal spermatozoa. We failed to demonstrate any relation between the AST activity and sperm concentration (r = 0.023; P greater than 0.05). However, a statistically significant relation (P less than or equal to 0.05) was demonstrated between the AST activity and percent occurrence of morphologically abnormal spermatozoa (r = 0.343). Applying the above results and in agreement with literary data, determination of AST activity in the seminal plasma of boars can be considered as an important indicator of the cellular damage of sperms.
