According to Science Daily,Australian Scientists believe a gene called SRY plays a huge role in a Males response to stress. Dr Joohyung Lee explains that men tend to express the aggressive "fight or flight" response much more frequent than women in a stressful situation. The SRY gene is found on the Y chromosome and is understood to be vital in forming the testes for males. Recently SRY protein has been found in the brain "controlling movement via dopamine". According to Medical News Today , Dopamine is conventionally understood as a product of a rewarding stimuli. Recently it has been discovered that aggression is processed as a reward in the brain; therefore, dopamine is produced. This may explain the presence of the SRY protein in the brain with dopamine activity. Science Daily also found SRY protein in the heart and lungs, which proves it serves a purpose further than sexual determination. Since the heart and lungs are involved in stressful situations this clearly indicates SRY could prime the organs to respond to stress in a different way to prepare for aggressive behavior. An increase in catecholamine and blood will enter the organs allowing a fight or flight response to take place. Females utilize oestrogen and opiates to remain calmer in stressful situations. It is amazing that the SRY gene originally believed to only form the testes plays such a role in a male's aggression during a stressful event. I certainly believe other factors play a role in an individuals response to stress; however, it is pretty clear that the SRY gene has a major influence on a Male's behavior.

This post is very enlightening. Whenever my father is stressed he always results to irrationally yelling instead of calmly dealing with his problems. This gave me a little insight into why he is this way, I've wondered for years.
