Both the risk and potential payoff are far greater for male then female. A woman can hope to have around 5-6 surviving children, with little risk to have none. A male has a real risk of dieing without children, but on the other hand the best case scenario is in the hundreds of offspring.

But the real consequence of a bigger male-to-female ratio will probably be plain old fashioned competition. Some men, especially young, will go the "flashy" way, but for most it will simply mean that having outstanding performance in whatever they do is much more important. Wouldn't want to be one of them, but for the society as a whole is probably good.
