Oral administration of an organophosphate pesticide, phosphamidon, at sublethal doses caused a decrease in both and testicular acetylcholinesterase (AChE), paired testicular weight, seminiferous tubular diameter, and the number of tubules containing healthy germ cells in the testes of adult whitetroated munias in a dose and duration depended manner.While no significant changes in the cytomorphology and nuclear diameter of Leyding cells were noted in the testes of the experimental birds, a significant negative correlation was observed between the number of semiferous tubules containing degenerated germ cells and the rate of AChE activity in both the testes and in the brain of respective bird groups.These findings demonstrate for the first time that the antigametogenic effects of an OP pesticide on avian tests may be due to impaired cholinergic functions in the brain and/or the testes in the birds concerned.
