I check for giant testes hanging under their tails. LOL

Seriously, of course male rats have nipples, every guy I know has nipples. If you are having problems sexing your rats, pick them up by the tail and let them grab on to the edge of their tub or tank. Then lower their rear ends below their heads like they are "hanging" off the edge by their front paws. If it is a male the testes will "fall" out and be visable to you from underneath.

Or if you look at animals that you know are males lift them up and look at the distance between the anus and where they urinate. It will be at least twice the distance than in females.

Good Luck!
Actually yep I do look for nipples I did another google search on it and everything is saying that male rats do not have nipples. I didn't go to the petstore and get full grown adults I got young rats. I'll try the dangling them off something though never thought about that with the young ones that suck it up does that still work? Oh and here is a link to a hairless male and yep no noticeable nipples, not to be sarcastic but wanted confirmation for myself.

Maybe there is a member here that has a hairless male that can confirm if they are just so small they are not recognizable in photo though.
