Recent research has found that the presence of male scents can stress out male mice. And this is pretty significant, as it’s important that research studies are able to be replicated. This will likely have an impact on behavioral studies going forward- and that’s a good thing!
It’s extremely important to minimize variables in research. Animals in research settings are often the best tools at a researcher’s disposal, due to this very reason. Unlike human subjects, research animals are able to be monitored extremely carefully in order to understand exactly which variables are significant. By understanding the effects of male scents on male mice, researchers have more information at their disposal as they attempt to minimize variables in their research studies.
By recognizing the fact that the gender of the researcher can have an impact on research outcomes, hopefully fewer animals will be needed to give statistically significant results. It’s also likely that researchers may now be able to understand why certain studies can be difficult to replicate. It’s commendable that researchers at McGill University in Montreal were able to provide this information to the research community. Read more about it here:
