Telling the sex of a young iguana is very difficult and it is hard to determine whether they is male or female until they reach about two years of age. One of the easiest ways to find the sex of a juvenile iguana is to look between the thighs for enlarged pores or scales called "femoral pores". Males tend to have large femoral pores, so large that they can even protrude from the skin, so they can grip tightly onto the female during the mating season. Another feature that is prominent in males is found near the vent area. Some males develop lumps or bumps near the vent, called "hemipenal bulges". These are part of the males reproductive organ, so are not present in the female. The head can also give a clue as to the sex of the juvenile or adult iguana. The heads of the male tend to be squarer and larger, with larger jowls, than that of the female. Yet another tell-tale sign of the sex is that female become gravid and will lay eggs. Males on the other hand will become more aggressive when adult hood approaches and will also grow larger than the female. Males also have a much larger appetite and will tend to eat much more than the females. If the iguana is at least a year old, you can usually tell the sex of the iguana. If you look at the femoral pores on the thighs of the iguana, the pores will look larger and will look white on a male. They use the pores to mark their territory during breeding season. A female will have much smaller pores. Males have larger dewlaps and jowls (cheeks and beards). Males have bumps on their back legs called femoral pores which are much harder to see in females. If its a baby though, you may not be able to see these differences. If you really need to know the best option is to take the iguana to a vet who will be able to tell you for sure. I can tell pretty positively once they are about 2 years old but much younger than that and its not for sure. Also the spiny crest on the iguanas back is moderately larger for a male.
