One group of animals was sacrificed after exposure, while another group received distilled water for an additional period of 35 days, in order to study the spermatoxic effect and the recovery of spermatogenesis. In mice sacrificed after NaAsO\n                    <jats:sub>2<\/jats:sub>\n                    exposure, a decrease in testis\/body weight ratio and reduction of tubular diameter were observed.
