I dunno much about Men's rules, as I'm not a guy, but you can look up more than what's here.
Full contact, exceptions only on potentially harmful attacks
7/10 players must remain on defensive side
Out-of-Bounds when over lines
Stick length varies according to position
Protective equipment required (lots of stuff. Kinda like football)
