ABSTRACT
Background:
Organophosphate insecticides represent one of the most widely used classes of pesticides with high potential for human exposure in both rural and residential environments.Objective:
In the present study; we investigated the effects of pirimiphos-methyl (0; 2-diethylamino-6-methylpirimidin-4-yl O; O-dimethyl phosphorothioate); an organophosphothioate pesticide; on male rat reproductive performances.Methods:
A total of 24 adult Wistar rats were divided into 4 groups of 6 animals each and orally treated with 0; 41.67; 62.5 or 125 mg/kg of pirimiphos-methyl for 90 days.Results:
Results from the study showed a significant increase (p0.05) in feed consumption; body weight gain; relative testis and epidiydimis weights and intra-testicular cholesterol level in rats receiving the test substance at doses of 62.5 or 125mg/kg whereas a significant decrease (p0.05) in serum total protein; sperm density and motility; fertility and parturition indices and pups sex-ratio (M/ F) was recorded in animals treated with 125 mg/Kg of pirimiphos methyl. Histological findings also indicated enlargement of interstitial space; inhibition of spermatogenesis; rarefaction of Leydig cells and oedema in testes compared to control animals.Conclusion:
It could then be concluded that pirimiphos-methyl (62.5 and 125mg/kg) is detrimental to the reproductive potentials of male rats
