@Andy210 The defeats the point of sexual reproduction, which is to introduce genetic diversity into offspring, which would increase the chance of a species's survival in different conditions. Asexual reproduction carries a high risk of mutation and that offspring will show similar phenotypes to that of incest in sexually reproducing animals.
That and having that kind of body is just not ergononmic and minimizes the benefits of human anatomy in favor of becoming a strange ball creature that scuttles around like a spider. It would litter ally be out competed by anything
Despite what it says, the androgynous aren’t really a new race or whatever of humans. It’s still just a host for the parasite. The host may not survive in the wild but it would definitely live long enough to infect/eat other humans. The ability to asexually produce more hosts is just an added bonus.
By the way, it won’t be outcompeted because nothing preys on its natural food source, humans.
