I'm not sure about the Werewolf group at the end of WWII, but the original word was not to do with war. Or only obliquely, via testosterone. In the earliest form of English, the noun which was to become 'man' meant both male and female, like 'homo' in Latin. It was modified to 'wifman', which became 'woman', analogous to 'femina', and to 'wereman' for the male, analogous to 'vir' in Latin. And 'were' is very closely related to 'vir'. It just means a male human.

Which is entirely irrelevant to the thread, except that it may be another urban myth.
