pseudohermaphrodite has 1 distinct synonym spread across 1 of its 2 senses. Each sense below keeps its own list, because a synonym belongs to a meaning and not to a word: swapping one sense's substitute into another sense's sentence is how a thesaurus makes writing worse. WordNet records no antonym for it — antonymy is a relation between word forms rather than concepts, so it is deliberately sparse.
someone having external genitalia of one sex and internal sex organs of the other sex; not a true hermaphrodite because there is no ambiguity in the sex of the external genitalia and hence no question about gender at birth
having internal reproductive organs of one sex and external sexual characteristics of the other sex
