Any toxicant that affects Sertoli cell development can potentially disturb male fertility. So far, the effects of organochlorine compounds have been poorly investigated in male. Here, we studied the effects of dichlorodiphenyltrichloroethane (DDT), an organochloride pesticide, on Sertoli cells. DDT inhibited the cAMP response to follicle-stimulating hormone (FSH), the major endocrine control of Sertoli cell development, and to a β2-agonist, isoproterenol. DDT exposure decreased the level of FSH binding sites. Direct adenylyl cyclase activation by Forskolin was unaltered by DDT, while the activation of Gαs by cholera toxin was decreased by DDT. The DDT inhibitory effect on the FSH response was also observed in Ser W3 cells, a Sertoli cell-derived immortalized cell line. All these effects were reproduced by the lipophilic aromatic bisphenol A but not by structurally unrelated CisPlatin. In conclusion, these results are a first step in understanding the molecular basis of DDT deleterious effects in spermatogenesis.
