Analysis of serum and seminal plasma after feeding ochratoxin A with breeding boars.
The aim of the experiment was to investigate whether or not ochratoxin A (OA) can be detected in seminal plasma after feeding the toxin in five and 10 times of the human tolerable daily intake with breeding boars and how toxin profiles of serum and seminal plasma correspond to each other. In addition to that, the effect of the toxin challenge on motility and longevity of boar semen was also evaluated. OA from samples was analyzed by microplate ELISA. Percentage of progressive motility of spermatozoa was determined initially and after 24, 48, 96, 120 and 144 h of storage. OA appeared in serum and seminal plasma shortly after toxin application had started. Significant reduction of initial motility and impaired longevity was observed after toxin withdrawal. These findings suggest that OA might have the potential to affect sperm production and semen quality of boars, but further research is required to elucidate whether OA exerts direct effect on germinal epithelium or disturbs sperm cell maturation only.
