Misogyny - Hatred of women Blank - Hatred of Men

What is equivalent of misogyny that means a hatred of men?

Misandry.

And if you hate both you are a misanthrope.

For a tool on-line that can (often, not always) answer this sort of question:

OneLook Reverse Dictionary

(Entering “hate men” turns up misandry as the first response (although it does not turn up misanthropy until somewhere in the 30s).

With clear parallels to the other pair of words:

polyandry - having more than one husband at a time
polygyny - having more than one wife at a time

a lycanthrope ? :smiley:

And, of course, “androgynous”.

Not to be confused with polygamy - having more than one spouse at a time.

And having two wives is bigamy
