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

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
