A paired couple of Schistosoma mansoni. Schistosoma mansoni is a water-borne parasite of humans, and belongs to the group of blood flukes (Schistosoma). The adult lives in the blood vessels (mesenteric veins) near the human intestine. It causes intestinal schistosomiasis (similar to S. japonicum, S. mekongi, S. guineensis, and S. intercalatum ...
The adult male and female are paired together, exit the liver via the portal venous system, travel to the venous systems of the intestines or bladder (species dependent), and produce eggs. Each species lays its eggs in specific parts of the body.
Schistosoma is a genus of trematodes, commonly known as blood flukes.They are parasitic flatworms responsible for a highly significant group of infections in humans termed schistosomiasis, which is considered by the World Health Organization to be the second-most socioeconomically devastating parasitic disease (after malaria), infecting millions worldwide.
In 1858 Weinland proposed the name Schistosoma (Greek: 'split body') after the male worms' morphology. Despite Bilharzia having precedence the genus name Schistosoma was officially adopted by the International Commission on Zoological Nomenclature. In 1898 all the then known species were placed in a subfamily by Stiles and Hassel.

Adult Schistosoma haematobium has male and female, which are permanently paired (a condition called in copula) as what looks like an individual. The male forms the flatworm part, measuring 10–18 mm in length and 1 mm in width. It bears oral and ventral suckers towards its anterior end.
Schistosoma japonicum is an important parasite and one of the major infectious agents of schistosomiasis. This parasite has a very wide host range, infecting at least 31 species of wild mammals , including nine carnivores , 16 rodents , one primate (human), two insectivores and three artiodactyls and therefore it can be considered a true zoonosis .
This list of related male and female reproductive organs shows how the male and female reproductive organs and the development of the reproductive system are related, sharing a common developmental path. This makes them biological homologues. These organs differentiate into the respective sex organs in males and females.
