Reproductive toxicology of acephate in male mice.

The reproductive toxicity of the insecticide acephate was studied in male mice. Adult male mice were treated by gavage with acephate at doses of 0, 7, 14, and 28 mg/kg/day for 4 weeks before mating with untreated females. Signs of cholinergic effects were observed in the 28 mg/kg/day group. Brain and skeletal muscle acetylcholinesterase activity was inhibited only in this group. Acephate treatment was associated with a decreased number of implantations and live fetuses, and an increased number of early resorptions at 28 mg/kg/day. The percent morphologically normal spermatozoa was unaffected in all dose groups; however, sperm motility and count were decreased in the 14 and 28 mg/kg/day groups compared to the control. Histologic examination of brain did not reveal any abnormalities. Dose related histologic changes, including degeneration of muscle fibers, were observed in the muscles of male mice treated with any of the doses of acephate. The current study demonstrated adverse effects of male acephate exposure on pregnancy outcome with effects on sperm parameters at 14 and 28 mg/kg/day.[1]
