While MRI taken on gynephilic male-to-female transsexuals have likewise shown differences in the brain from non-transsexuals, no feminization of the brain's structure have however been identified. Researchers of the Karolinska Institute of Stockholm used MRI to compare 24 gynephilic male-to-female transsexuals with 24 cisgender male and 24 cisgender female controls. None of the study participants were on hormone treatment. The researchers found sex-typical differentiation between the MtF transsexuals and cisgender males, and the cisgender females; but the gynephilic transsexuals "displayed also singular features and differed from both control groups by having reduced thalamus and putamen volumes and elevated GM volumes in the right insular and inferior frontal cortex and an area covering the right angular gyrus ".

Learning theory is based on the principles of behavioral psychology, which hypothesizes that a person’s behavior is learned and maintained by its consequences or rewards. Individuals thus learn deviant and criminal behavior by observing other people and witnessing the rewards or consequences that their behavior receives. For example, an individual who observes a friend shoplift an item and not get caught sees that the friend is not punished for their actions and they are rewarded by getting to keep the stolen item. That individual might be more likely to shoplift, then, if he believes that he will be rewarded with the same outcome.
Another theory suggests that genital hair protects the reproductive organs, especially the vagina, from dirt and particles. However, there’s one problem to this theory: It only applies to women. If it is applied to men then there should also be pubic hair protecting the urethra.
