Femoral pores can be found near the un­der­side of the base of their tail and par­tic­u­larly on their back legs. They con­tain sev­eral unique glands that emit pheromones and look dis­tinctly dif­fer­ent de­pend­ing on the sex. Check­ing out an iguana’s femoral pores is one of the best ways to de­ter­mine their sex at an early age, es­pe­cially since they don’t have ex­ter­nal gen­i­talia.

Males would have a waxy ob­ject protrud­ing from the pores which forms a comb-like shape, whereas fe­male femoral pores are plain flat. These char­ac­ter­is­tics usu­ally start ap­pear­ing af­ter around 12 months.
