Once entering the bloodstream, most toxic substances, including pesticides, can reach organs involved in the reproductive system. They can cross the placenta, as well as the brain barrier, posing various risks to the reproductive processes. The organochlorine insecticide lindane and the s-triazine herbicide atrazine produce changes in hormone-dependent reactions in the rat hypothalamus, anterior pituitary, and prostate. Lindane also causes histological and biochemical alterations in the rat testis. In vivo treatment with atrazine produces a markedly inhibitory influence of 5{alpha}-dihydrotestosterone - receptor complex formation in rat prostate cytosol. Therefore, the aim of this study was to investigate whether such changes in the crucial step in the reproductive process are reversible. A parallel investigation using lindane was also undertaken.
