If a misogynist is a man who hates women, what is a woman who hates men?
Probably the antonym is womaniser, but what is the word for a woman who hates men?
A woman who hates men is a "misandrist", although you won't hear that word very often.
There doesn't seem to be a similar word for a woman who loves men. The word you'd expect -- "philanderer" (because it's Greek for "lover of men") -- in fact describes very specifically a man who has sexual relations with women without intending to marry them -- a "womaniser", in fact.
