Alpha-cypermethrin (α-CYP) a synthetic pyrethroid (type-II) pesticide. Pyrethroid insecticides have been used in agricultural and home formulations for more than 30 years. Despite their extensive worldwide use, there are relatively few reports of the kinetic profile. Dissolved in alcohol was given to male albino rat for 24hr individual groups at 5, 10, 25 and 50mM dose for each group. The animals were sacrificed after 24hr duration. Biochemical studies were observed in testis. Increased the activity of alkaline phosphatase(ALP) at 24hr duration, while decreased acid phosphatase(ACP) at respective duration. Therefore low doses of alpha-cypermethrin altered testicular biomarker enzyme activities. This may interfere in the functioning of the reproductive system of albino rat.
