Femoral Pores

It is essential to let your Iguana reach its sexual maturity before you look to know if your pet is male or female. Once an Iguana reaches sexual maturity, some distinguishing characteristics will become more pronounced, including the female pores.

If you look at the underside of your Iguana’s hind legs, the female pores will be visible, starting at the vent and ending at the knee. Additionally, male Iguana also has larger female pores, easily seen during the mating season.

If you have made it, you need to be aware that they tend to leave a waxy trail behind on the surface to mark their territory in the breeding season. In the breeding season, the most common species of Iguanas will develop waxy plugs that grow from their pores.

It is essential never to wear down or clean out the wax coming out from your male Iguana’s pores as it is intentional by your pet. It would help if you were concerned because removing the wax plug from your Iguana can damage your pet. On the other hand, females lack as many pores as males and are not larger than male Iguanas.

Fat Pockets And Longer Spikes On Their Head

Again, it is essential to wait for your Iguanas to reach sexual maturity to get more pronounced characteristics distinguishing the male and female. Once an Iguana reaches sexual maturity, the males start to develop fat pockets on the back of the heads.

It is straightforward to locate the bumps formed on your male Iguana’s head. Female Iguanas lack this fat pocket, and female Iguanas usually have a very smooth authority. Apart from the overweight bag, the spikes of your male Iguanas will also be significantly longer than the ones found on females of the same species. Females have shorter spines and are thinner, which gives you another opportunity to recognize whether it is male or female.

Hemipenal Bulges

Depending upon the species, male Iguanas tend to have two bulges under their belly located near their vent. It is pretty easy for you to find it when your pet is either on its back or side. These bulges are also known as semi penal bulges, which are only present in male species of Iguanas, and females will lack these bulges.

Additionally, male Iguanas’ bulges also cause their tail to grow thicker and not taper off like females. In females, it is pretty easy to notice their tails taper down immediately after the vent. In one sentence, we can say that the two oval-shaped bulges are visible on the males, whereas the female will have a single but more circular bulge directly above the vent.

When deciding on a pet, you must know why you are getting one. If you are thinking of breeding iguanas, then knowing the gender is highly critical to determine if the chosen pet is a good choice for you or not. If you are not breeding them and only getting one for companionship, you must know that both males and females have similar personalities or temperaments.

They also exhibit identical health that relies heavily on their habitat, environment, and care. In the breeding season, regardless of whether your pet has a mate or not, both sexes of Iguanas will exhibit some change in their behavior and body.

The most important thing that you need to consider when deciding on the best pet for you is to know whether you can adequately care for them or not. Whether mate or female, having an Iguana is a long-term commitment that can never be taken for granted. If you want to adopt an Iguana, then there are a few things that you should know.


Before you adopt any pet, always look out for the amount of space available in your room or home. If you consider keeping your Iguanas enclosure in a very tiny spot, choose the female iguanas. The male Iguanas tend to grow bigger and thicker and often need more space for their well-being.

It is essential always to get your Iguana a room that allows them to climb, move, roam, play, bask, sleep, rest, and explore freely. This is why it is essential to evaluate the amount of area you can offer to your friend. Choosing a spacious enclosure of at least 55 gallons in size is always recommended. If you are thinking of keeping them in a small section, you should reconsider getting any pet.

You can never know whether your pet is male or female until it is sexually matured. This is why it is always recommended to get the pet checked before adopting one. There is less chance the pet store or the breeder will allow you a short visit to the nearest vet.

Therefore, it is essential to permanently adopt a pet from a reputable breeder who also offers health insurance. Do ask all the questions regarding the gender and the care of your pet. If you want a specific gender of Iguana, then I will highly recommend you always adopt an adult Iguana that is already tamed and raised by humans.

Desired Temperament

If you are looking for a pet with a specific personality, I would recommend you to dig thorough research. Before adopting any pet, you should know that male iguanas are way more aggressive than females, especially during the breeding season. However, male Iguanas are also more adventurous and curious reptiles than females.

If the male Iguanas get proper training and early socialization, they can be raised into well-behaved friends. Talking about female Iguanas, they tend to have a more hermit-like nature. Rather than being touched or held by any human, female Iguanas prefer their own company.

Multiple Pets

If you are thinking of breeding, you might be looking to adopt multiple Iguanas. On the other hand, if you want to have more than one reptilian friend, it is recommended to choose the female ones. In the case of breeding, always go with a single male and one or more females at first. Do you know that male iguanas can never be kept together in the same enclosure?

Male Iguanas can be pretty combative in the breeding season. Keeping two or more males together in the same tank can result in a territorial fight, fight over food, and unwanted stress. All these can result in injuries and even death for one of your reptilian friends.


You know that both males and female Iguanas are trendy pets but keeping them in an enclosure can be tricky. It can be challenging to make up your mind about the kind of friend you want if you only look at specific factors like gender alone.

It is essential to consider other aspects like their diet, care, space, humidity, etc. Do you know that male Iguanas tend to be more fun, curious and notorious? If you are looking for a calm and sedate type of friend, I recommend you always go with the female Iguanas.

Remember that whichever gender of Iguanas you choose will still need proper care, attention, and love to lead a happy, healthy, and long life.
