No, as we have both quoted, and you miscounted, there are four states:
- Male (gonochoric) - Female (gonochoric) - Sequential hermaphrodite - Non-sequential hermaphrodite
True hermaphrodite is a misnomer, a term for an intersex disorder known as ovotesticular syndrome[0]. To quote the great Wikipedia:
> In the past, ovotesticular syndrome was referred to as true hermaphroditism, which is considered outdated as of 2006. The term "true hermaphroditism" was considered very misleading by many medical organizations and by many advocacy groups, as hermaphroditism refers to a species that produces both sperm and ova, something that is impossible in humans.
To check, we can apply "our" quote - a hermaphrodite would either be sequential, which we know humans are not (I hope we know that much), or able to produce both types of gametes at the same time.
True hermaphrodites cannot do that, and the paper you shared makes no claim that they can or that they have. None of the examples show that either.
Your claim is false.
> Not all humans reproduce.
I'm sorry, but you're bringing the conversation down to a level too silly to bother with there. Every human has a reproductive strategy, and from conception to boot. Whether any individual actual reproduces is irrelevant to that.
Really, that kind of argument is beneath the level of this forum.
