I'm pretty sure my iguana is female. She's almost 3 and never laid eggs. Her behavior changes in fall each year. She gets restless and wants out all the time, followed by fatter belly and subdued activity. Her legs get orange. But then she thins out, sheds and goes back to normal without getting sick or laying an egg. I got her as hatchling an am fairly certain of her age. She has no male traits. No pores no bulge no "deposits". Shouldn't she have laid eggs by now? She is over 3' long.
