The use of insecticides has been increasing along with increasing agriculture activities and has caused deleterious environmental impacts. Non-target organisms in particular, including fish, are affected by pesticides. In this work, the impacts of cypermethrin (CYP) on sperm oxidative stress markers and sperm motility were investigated in vitro. The CYP concentrations were 0 μg L-1 control, ethanol), 1.025 μg L-1, 2.05 μg L-1 and 4.1 μg L-1. Lipid peroxidation [Malondialdehyde (MDA)], non-enzymatic antioxidants [glutathione (GSH)] and enzymatic [superoxide dismutase (SOD), glutathione peroxidase (GSH-Px) and catalase (CAT)] activities in sperm cells were examined for determination of oxidative stress status. Our findings showed that motility and survival of sperm cells significantly decreased with exposure to CYP. Biochemical assays revealed that CAT activity and levels of MDA and, GSH increased in spermatozoa based on CYP concentration while activity of GSH-Px and SOD decreased. Consequently, spermatozoa were highly sensitive to CYP exposure. It can be deduced that CYP has the potential to disrupt sperm quality and to cause to oxidative stress in sperm cells of S. coruhensis.

The use of pesticides has been increased along with increasing the farming activities and has caused environmental impacts deleteriously. In particular, non-target organisms including fish can be affected by toxic effects of pesticides. Therefore, the impacts of malathion (MTN) on oxidative stress and sperm quality were investigated in vitro. The MTN concentrations used on this study were 0 (control), 75, 100, and 125 μg/L. Lipid peroxidation (MDA), non-enzymatic (GSH), and enzymatic (SOD, GSH-Px, and CAT) activities in spermatozoa were examined for determination of oxidative stress status. Our findings showed that motility rate and period of sperm cells significantly decreased with exposure to MTN. Biochemical assays revealed that CAT activity and levels of MDA, GSH increased in spermatozoa based on concentration while activity of GSH-Px and SOD decreased. Consequently, spermatozoa were highly sensitive to MTN exposure. MTN has disruptive effects on sperm quality and caused to oxidative stress in spermatozoa.
