Are You a Mouse and a Man?

An American scientist has repeated a claim that I (and colleagues) made years ago, namely that focusing drug research exclusively on male animals probably does not capture the full potential range of effects and side-effects that might be expressed in human populations when the treatments become used medically (https://www.theguardian.com/science/2019/may/31/sexist-research-means-drugs-more-tailored-to-men-says-scientist). It is suggested that preliminary research (especially on proposed psychoactive drugs) should include both female and male animals.
