Female rats are not more variable than male rats: a meta-analysis of neuroscience studies

Conclusions < /h3 > < p class= " a-plus-plus " > We conclude that even when female rats are used in neuroscience experiments without regard to the estrous cycle stage, their data are not more variable than those of male rats. This is true for behavioral, electrophysiological, neurochemical, and histological measures. Thus, when designing neuroscience experiments to include both male and female rats, power analyses based on variance in male measures are sufficient to yield accurate numbers for females as well, even when the estrous cycle is not taken into consideration. < /p > < /span >
