Abstract: ContentsDecline of semen quality due to endocrine‐disrupting chemicals is of concern globally. Among endocrine disrupting chemicals (EDC), Polychlorinated biphenyls (PCB) are associated with reduced semen quality in various epidemiological studies. In this study, we evaluated the direct effects of selected PCBs (28, 30 and 118) on fresh spermatozoa of Simmetial bulls aged 2–4 years were evaluated in vitro by 3‐(4,5‐dimethylthiazol‐2‐yl)‐2,5‐diphenyltetrazolium bromide (MTT) assay and computer assisted semen analysis (CASA) (SCA;...
