Objective: To assess the adverse effect of Deltamethrin (DM) (technical grade) on
reproductive organs and fertility indices of male Swiss albino mice, Mus musculus.
Methods: Forty male mice were divided into four experimental groups: control, vehicle
control (peanut oil), high dose DM treated and low dose DM treated group. An oral dose
of 3 mg/kg b.wt (low dose) and 6 mg/kg b.wt (high dose) of Deltamethrin was administered
for a period of 45 days to male Swiss albino mice.
Results: DM caused a significant reduction in body and organ weights, sperm count,
sperm motility percent, sperm viability, serum testosterone level, sialic acid content of
cauda epididymis and fructose level of seminal vesicle. DM-treated groups also showed a
significant decline in testicular 3b and 17b Hydroxysteroid Dehydrogenase (HSD) activities.
Histological examinations revealed significant alterations in the testes of dosed
groups.
Conclusion: Deltamethrin is a toxic pyrethroid pesticide that produced significant
reproductive toxicity in treated male mice as revealed by the severely affected parameters
and the altered gravimetric indices.
