Coiro and Pollak in a 2019 reviewed 432 articles examining the effects of infection during gestation on the behavior of offspring.  They found that research preferentially studied male offspring.  Of these studies, ~40% examined only male offspring, 40% examined both female and male offspring, and <3% examined only female offspring (many studies did not report offspring sex).  Even when both daughters and sons were used, sex differences were not always evaluated.  The authors speculate that “this neglect of female subjects in basic research may stem from a hard-wired sex/gender bias, which may also be reflected in a similar attitude toward female scientists”.
