Sex!

We've got an Argentine B&W tegu, about 4 years old. We believe him to be male, but some recent discrepancies with our snakes has left me with a small inkling of doubt in my mind... How do you determine sex, for sure?

At 4 yrs old there should be no doubt one way or the other. If it's male then it will have jowls, two bumps, one on each side just below the cloaca (they feel like pimples or bb gun pellets) and it will invert it's hemipenes when it poops as well as leave sperm plugs. If you see none of that then its female.

I haven't taken a good look/feel around the cloaca, but I have definitely seen those sperm plugs (I looked at another thread you posted on, where there was a photo for reference). I always kinda wondered what that stuff was. Thanks for the info!
