Andre Zelikov UMiD= 20475672 Psych 481 Media and Violence Effects of Testosterone and Aggression Testosterone is an androgen hormone secreted from the testicles, ovaries, and adrenal glands. It serves multiple roles in both males and females by regulating libido, immune function, energy, and bone density. Primarily viewed as a male sex hormone and anabolic steroid, levels of testosterone correlate to the development of secondary sex characteristics in males such as body hair and muscle mass. Testosterone has also been attributed to aggressive behavior in both men and women. Numerous studies analyze the effects of environmental and biological contributions to the production and regulation of testosterone as well as its effect on the body. Based on the studies, levels of testosterone correlate to an individual’s level of aggression in both males and females. Many individuals over emphasize the direct correlation between testosterone and aggression. Testosterone and aggression do no have a relationship where high levels of testosterone promote an individual becoming berserk. Biological systems are vastly complex and single intermediary chemicals may have the potential to mediate aggression. A wonderful example of such an intermediary is a metabolized version of testosterone which is a female sex hormone which regulates testosterone (Nelson 2001). Based on the vastness of biological systems and studies conducted on testosterone, it can be deduced that testosterone serves as a marker due to its relative size and numerous derivatives, many of which moderate bodily functions. While other chemicals are more difficult to trace in an organism, testosterone centralizes itself in a readily assessable area that can be augmented to the researcher’s needs. Even though society establishes testosterone as the 1 1

Andre Zelikov UMiD= 20475672 Psych 481 Media and Violence life spring for aggressive masculinity, there is a causal relationship between testosterone and aggression, but it is not as direct as once believed. “The He hormone has become a metaphor for manhood. . .” (Zittsman 2001) describes society’s view of testosterone. Testosterone itself accounts for many of the secondary sexual characteristics that define the male gender in regards to strength, energy, and dexterity. Animals also experience similar sexually dimorphic characteristics, but unlike humans, their dimorphic behavior is more easily observed. Animals, such as birds, display behavior characteristics that are unique to gender. Barn swallows are such polygamous birds that display dimorphic behavior traits. Their levels of testosterone directly correlate to aggressive mate guarding during breeding seasons (Saino 1995). During breeding, females often copulate with multiple males in order to insure fertilization while males guard females to ensure paternity. Mate guarding and testosterone in male swallows increase to their maximum during periods where females are most receptive (Saino 1995). Even though direct causation cannot be determined

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
