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), with hundreds of millions infected worldwide.
The copula happens through the coaptation of the male and female genital orifices. [7] The female has a cylindrical body, longer and thinner than the male's (1.2 to 1.6 cm long by 0.016 cm wide). It has the general appearance of a roundworm. The female parasite is darker, and it looks gray.
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.
The process in which the adult male worm holds the adult female worm is called in copula and is when they are paired. [11] When first identifying S. hippopotami as a species, Thurston made some simple identifications about the female and male morphologies of S. hippopotami. The female is typically shorter than the male; she has an ovary that is ...
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.

Blood flukes (Schistosoma) are the only form of trematodes that are dioecious (have both a male and female sex). Blood flukes are unique in the way that they can undergo both asexual and sexual reproduction. Asexual reproduction occurs in the hepatopancreas of a freshwater snail, which serves as an intermediate host. Sexual reproduction occurs ...
From ancient history to the modern day, the clitoris has been discredited, dismissed and deleted -- and women's pleasure has often been left out of the conversation entirely. Now, an underground art movement led by artist Sophia Wallace is emerging across the globe to challenge the lies, question the myths and rewrite the rules around sex and the female body.
