That's all conjecture. If VCs get a sense that a male moonshot founder wants work life balance, for example, they are unlikely to invest. It's not about gender and discriminating on that kind of surface level. There are always exceptions of course, but it's not useful or reality based to extrapolate those into the rule.
Some more stats to think about, which seem to avoid these kind of conspiracies about bias or patriarchy: 93% of prison inmates are men. 70% of homeless are men. 97% of preschool and kindergarten teachers are women. 1.9% of carpenters are women.
