Organophosphorus insecticide induced decrease in plasma luteinizing hormone concentration in white-footed mice Organophosphorus insecticide induced decrease in plasma luteinizing hormone concentration in white-footed mice

Oral intubation of 50 and 100 mg/kg acephate inhibited brain acetylcholinesterase (AChE) activity by 45% and 56%, and reduced basal luteinizing hormone (LH) concentration by 29% and 25% after 4 h in white-footed mice (Peromyscus leucopus noveboracensis).
