>>12183714To provide a means for reproduction and dispersal for the parasite which causes it.
It affects the neural processing of the infected host, leading it to believe it is female and thus exhibiting female-like mating behavior. The behavior is usually hyper-sexual in order to help promote the spread of the parasite and facilitate its life cycle. As a result the majority of transsexuals are highly promiscuous and tend to exaggerate female characteristics, imitating a male's idealized version of a female in their own minds.
Uninfected males who have sexual contact with transsexuals are likely to become vectors of the parasite and spread it onto male children in their immediate vicinity. That can include immediate family, children of associates and through social establishments such as schools, clubs, sports.
It is theorized that one reason many cultures
have an aversion to transsexuals is that it functions as a social adaptation to help prevent the spread of the parasite, whose exact identity remains unknown to science at this point. It is however suspected to be some form of virus, fungus or perhaps protozoa. Possibly a cooperative or symbiotic relationship existing between two species of parasites cohabiting the same species of host.
