It would be dangerous to incubate (keep and grow) cultures at temperatures close to body temperature (37Â°C) because doing so might allow the growth of pathogens harmful to health. So the maximum temperature used in school and college labs is 25Â°C.
Hormonal changes accompany the onset of incubation, with levels of prolactin in the bloodstream increasing and levels of testosterone falling. The ideal temperature for most species to incubate their eggs is c. 38Â°C and this is achieved by developing a highly vascularised brood patch where heat from the body warms the eggs.
