I used to think were wolfs were real, but I know that their just stories, about men & women turning into were wolfs. That's rediculous but I do hear some religions about it being true... im not a %100 sure.I do know that the wolves we see in mountains and stuff are real and we call them were wolfs. But anyways here is some info I looked up about a man turning into a werewolf, hope this helps get some good references.

Lycanthropy is the professed ability or power of a human being to transform into a wolf, or to gain wolf-like characteristics. The term comes from Greek Lykànthropos (Λυκάνθρωπος): λύκος, lykos ("wolf") + άνθρωπος, ànthrōpos ("human").[1]
The word "lycanthropy" is sometimes used generically for any transformation of a human into animal form, though the precise term for that is technically "therianthropy". Sometimes, "zoanthropy" is used instead of "therianthropy".[2] The word has also been linked to Lycaon, a king of Arcadia who, according to Ovid's Metamorphoses, was turned into a ravenous wolf in retribution for attempting to serve human flesh (his own son) to visiting Zeus in an attempt to disprove the god's divinity.
A more modern use of the word is in reference to a mental illness called lycanthropy in which a patient believes he or she is, or has transformed into, an animal and behaves accordingly. This is sometimes referred to as clinical lycanthropy to distinguish it from its use in legends.
