Stress Versus Reproduction in Animals
Keywords:
Stress, reproduction, sympathetic nervous system, HPA axisAbstract
Stress can affect every organ system in the body, but the principal mediators of the response to stress are the sympathetic nervous system (catecholamines) and the hypothalamo-pituitary-adrenal axis (cortisol, adrenocorticotropic hormone & corticotropin releasing factor) (McEwen, 2005). Number of endocrine, behavioural, autonomic and immune responses are measured but none has proved a litmus test for stress. However, under controlled experimental conditions, cortisol can be a reliable indicator of stress.
