I would not put it past the stupidness I have seen from modern D&D rule books (granted those in D&D are called yuan-ti) or some online screechers but conventionally the race of anthropomorphised animals will have men be the suffix (snakemen, molemen, lizardmen, dogmen, wolfmen...) with the singular individual being man (snakeman, moleman, lizardman) and then female being a separate term (female snakeman, female moleman... or female snakemen for a group of multiple female snakemen/the female aspect as a whole) if it is relevant to the discussion (could be asexually reproducing, could be multiple genders necessary for reproduction, could be uniquely tweaked like that because of a curse/object of the gods...). There are exceptions like merman, mermaid and merfolk being one of the more well known (indeed mermaid probably being one of the few that covers all of them), and that is not even getting into the werewolf and things like that
