Abstract: | We hypothesised that massive elimination of human and animal progestagens through wastewater can be toxic for reproduction of amphibians. Several medical test using amphibian bioassays (i.e. Hogben test) have demonstrated that human chorionic gonadotropin is toxic for amphibians. Nowadays, a huge amount of sexual hormones from women, animal farms and aquaculture arrive to inland water systems and could be a cause of amphibians extinction. |
