title: [The question of pathogenesis of parasitic castration in snails infected with developmental stages of digenetic trematodes].
abstract: In the article several models of pathogenesis of parasitic castration of snails infected with developmental stages of digenetic trematodes are presented. Some aspects of mechanical and chemical damage of the gonad and changes in tissues of this organ, caused by its starvation--developing as a consequence of competition between the host and its parasites, are discussed. Particular attention was paid to potential effect of the parasitic larvae on physiology of the hormonal system of the host.
