In the domains I am familiar with -- computing, physics, math, economics, finance, and chess -- the vast majority of important contributions have been made by men, and even in the 20th and 21st centuries, when women are educated and pursuing careers, that continues to be the case, although the male/female ratio has fallen a bit. Although this does not of course justify discriminating against women, excluding males from opportunities may slow progress in these domain. Such exclusion does occur -- there are many efforts to teach computer science that exclude boys, for example.
