Iguana gender

Question
Good morning. I have an Iguana that I need to give up for adoption. We are promised a great home in a small zoo with 3 other Iguana. But only if she is a Female! We are pretty sure but the vet at the Zoo isn't. can I send you pictures to receive your opinion? Thank you for your help. Best regards Johann

Answer
If the iguana is an adult, I can try.  I am not a green iguana expert, but I do know what to look for.  If the iguana isn't an adult, than even an expert may not be able to tell.  It's a bit concerning that a veterinarian can't tell the animal's gender.
