I was thinking about this concept abstractly (deviations from the norm evolutionarily). I'm not trying to dispute the data you have here, but rather play the devil's advocate to propose an alternative theory which might contradict the data. I'll preface this by saying I already know the (correct and definitive) rebuttal to this line of thought, but it's fruitful to mention the problem nonetheless.

Men are the risky sex, relative to the propagation of the gene lineage. Men have a higher chance of not reproducing either as a result of sexual competition or death, but also the capability of reproducing many times in the proper scenario. Why does it make sense for men to be more variable? Why aren't women the variable sex?

Females get a huge advantage in reproduction of their genes: they are the gatekeeper of the gene line. An undesirable female will probably still reproduce, whereas an undesirable male probably won't. Why aren't females extremely variable instead of males? Females could biologically "get away" with extreme (but viable) variation because they're practically guaranteed to reproduce anyway. Males being extremely variable merely results in a lot of detritus at the edges-- wasted energy from the perspective of the parents / gene line. Isn't there an evolutionary pressure against wasteful reproduction?
