Conversely, the primary mechanisms of action involved in the reduction of testosterone are increased hypothalamus-pituitary-adrenal axis activity, inflammation, and oxidative stress. As the CDC explains, a variety of factors intrinsic to the host, sometimes called risk factors, can influence an individuals exposure, susceptibility, or response to a causative agent.2,3, Completing the triangle used by epidemiology to model the study of disease and health issues are the extrinsic factors that affect the agent and provide opportunity for the host to be exposed.
