It is well known that class Trematoda includes solely parasitic forms of flatworms. Therefore, they have developed diverse morphological and functional adaptations to the parasitic way of life. One of them is enormous fecundity, which allows quick and widespread settlement and finding hosts. Therefore, studying the reproduction apparatus of helminthes is the central problem of Parasitology. Studying functional morphology of the reproductive system of trematodes in general and its separate parts is of particular interest in addressing such a theoretically and practically important problem as direct regulation of endoparasites' fertility. This article presents thoruoug information about functional morphology of male reproduction apparatus in the Parastrigea robusta trematode, which is a parasite in the digestive system of common pochard (Nyroca ferina), which has not previously been studied and described in detail. As a result, the obtained knowledge about peculiarities of the structure of male reproductive system in trematode Parastrigea robusta will add substantially to the knowledge about particularities of the structure of male reproductive system of trematodes of Strigeidae family and endoparasites' fecundity in general.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
