There have been academic papers inspired by the Wikipedia gender gap, but this isn't one of them. This study examines differences among different Wikipedia localizations and only mentions male dominance in passing as a suggestion for future investigation.

It should really be expected that most political biographies are about men, given that the overwhelming majority of world leaders have been male. But some other gender statistics are less easily explained: http://wikisym.org/ws2011/_media/proceedings:p1-lam.pdf
