Male and Female Brain Differences

Researchers studied physiological arousal measured by genital temperature, wetness and swelling among males and females while viewing pornographic video. Subjects were “healthy” adult men and women along with females having different sexual orientations. These researchers employed [f M. R. I.] scans and measured activity differences in the brain. One purpose was to determine if there were brain activity differences between the sexes. The researchers also incorporated 61 previous research studies as well. They found no significant differences between the sexes pertaining to   sexual arousal. Their study also found brain activation in women that revealed similar brain responses to arousal as well as to photos of vomiting or feces. This sameness, opposite or combination was puzzling to say the least and not yet adequately explained.

One question raised, in the article, was why statistically are males the more frequent consumers of pornographic material?  It’s obvious, that arousal is one variable. However, a second variable relates to the behavior or motivation of the individual. One behaviorally can pursue pornographic material in order to become aroused. Of course there are other means for arousal. Second, we know that the age of an individual determines one’s testosterone and estrogen levels and these levels began to diminish in the 20s. Hormonal levels relate to sexual arousal. Third, we know that sexual behavior is affected by attitude, thoughts, feelings, mental health, mental illness, life satisfaction etc.

Turning to the brain, we also know that male and female brains are more alike than different. That cannot be said as far as sexual behavior between the sexes. We also know that the brain can be divided into three sections and sexual arousal is located in the hypothalamus which is located in the archaic brain where there are no significant male or female differences. Most differences, in the brain, are found in the third section -cortex. Within the left hemisphere, males exhibit less impulse control than females. Other executive functions found in the cortex {left hemisphere} include higher cognition, abstract thought, and use of language and social behavior. For females, their left hemisphere is usually their more dominant hemisphere.

 Furthermore, when there are frontal lobe abnormalities, the brain has difficulty regulating such things as inhibition or control of impulses and emotions, planning and organization, movement, overall social and cognitive behavior including judgment, and decision-making. Individuals with antisocial behavior-frontal lobe abnormalities  {more often men] are characterized by increased violence, impaired impulsivity,  poor judgment,  failure to conform to social norms, aggressiveness, disregard for the safety of oneself and others, glibness, inability to feel love and are more deceitful.

Related to arousal and viewing pornography was highlighted in a New York Times article.  For instance, in 1998 there were over 3, 000 reports of child sexual abuse imagery. 10 years later, yearly reports soared past 100,000. In 2017 there were 18.4 million reports that included over 45 million images of videos of child sexual abuse.

Difficulties like not enough funding for the various governmental  agencies  dealing with sexual criminal behavior, encrypted sophistication by social media  criminals, not enough regulations or oversite  by the tech companies, inadequacy or will of politicians, the diversion of government money from one agency to  another ie. Homeland security (to combat immigration], and the inability of all the agencies in keeping pace with the increased levels of abuse.

Pedophilia is a psychiatric disorder “pertaining to the act or fantasy of engaging in sexual activity with prepubertal children as an exclusive method of achieving sexual excitement.” Incarcerated individuals with this diagnosis reported that some engaged in child sexual abuse and then became involved in video and others reported that they initially watched video and then engaged in child sexual abuse. Incidentally, more males are incarcerated than females with this diagnosis.

Arousal, for the sexes, play an important role in human nature. However, the Internet makes it too easy to view pornography. Although there are no apparent arousal differences regarding erotic imagery between the sexes, the following is true: 1. More males have an antisocial behavior diagnosis 2. More males are incarcerated for sexual crimes 3. More males are engaged in online pornography 4. Males have more right hemisphere domination 5. More understanding regarding sexual behavior can be found in the executive functions of the cortex.
