Tehran University of Medical Sciences Iranian Journal of Psychiatry 1735-4587 19 4 2024 09 18 453 462 Sayed Ali Marashi Department of Psychology, Shahid Chamran University of Ahvaz, Ahvaz, Iran. 2024 04 30 2024 08 21 Objectives: Claims have been made that more sexual liberalism in society than what generally existed in human history is necessary to promote societal tranquility and reduce violence. This research was conducted to investigate the real relationship between sexual behavior and aggression based on scientific data especially from the perspective of physiological psychology. The present study investigates the hypothesis that unrestrained sexual behavior leads to an escalation of behavior, rather than satiation, and aggression rather than calmness. Methods: This study employed a theoretical review methodology and drew upon previous findings from neuropsychology, psychophysiology, laboratory research, and field studies. Results: The study's results indicate that uncontrolled sexual behavior can lead to an increase in Sexual desire instead of sexual satisfaction. This increase may be due to a positive feedback loop between the nervous and hormonal systems, specifically the Medial Preoptic Area (MPA) and testosterone. Experimental findings suggest that this physiological process may result in aggressive behavior. Conclusion: This paper establishes that the intensification of sexual behaviors leads to increased violence and aggression in society, ultimately elevating levels of public insecurity. Therefore, limiting sexual behavior within the framework of the relationship of married couples may serve as a moderating factor for this phenomenon. https://ijps.tums.ac.ir/index.php/ijps/article/view/3880
