IB Psych SRQ: Explain How One Hormone Influences Human Behavior

A horm i is a bio chemic produced by the glands of the endocrine formation which is transported by the bloodstream to specific cells and organs around the body in nightspot to initiate specific biological responses. The human race body spate produce a large number of hormones, many of which consider a large influence on our emotions and behavior. Common examples are adrenaline, oxytocin, oestrogen, and testosterone, which I lead be using to demonstrate the commodious influence which hormones have over our terrestrial lives.Testosterone is the hormone responsible for the development of secondary winding sexual characteristics in phallics (development of facial hair, compound of voice, increased muscle mass, etc.) and is secreted from the testes and ovaries, although only in small amounts by the latter. It is essential for return in males and has been strongly linked to truculent behaviors.One contemplate which adequately demonstrates this link is Bertholds 1840s study on the make of testosterone on animal behavior. In this quasi-experiment sise cocks were castrated. One group was left without nut cases, one had them surgically reattached, and one had another roosters transplanted. Both of the groups which had been given testicle transplants behaved normally (fighting, crowing, strong sex drive) condescension the fact that the testicles did not re-establish the connections they had originally had, magic spell the control group showed decreased levels of invasion and lack of desire to mate. Berthold concluded that the testes must be responsible for secreted some chemical which is linked to these behaviors.Because this study used roosters we can argue that the results should not be infer to fit humans, however, more recent explore has reinforced this link and I chose this study because it was one of the earliest and sparked further query into the area. This study demonstrated a guide cause-and-effect link between the testes and traditional male behaviors because removal the testicles directly lead to little dominant behaviors in the control group.
