Physiological and environmental conditions affect the capacity of reproduction and the drive to do so. Hyperthermia is caused by exposure to excessive heat, or combination of heat and humidity, that overwhelms the heat-regulating mechanisms. Mete (2012) opines that although regulation of body temperature and individual adaptation to environmental climatic changes are well documented, little is known about mechanisms and pathological aspects of hyperthermia. Heat stress is often blamed for suboptimal reproductive efficiency in males.Scientists have predicted that, not only will much of the...
