Do men have more extreme variations than women?
First of all for the first 22 chromosomes (and the mitochondrial chromsome) are the same between women and men. The X and the Y together are something like 1.5% of the total DNA in the human cell.  The X chromosome is also in common, so it has the same chromosomal (genetic) variations the same as women and men. 

While I am not sure about the differences you point out, its for sure there are lots of differences between the biology of men and women!  The reason that women's traits might have different variances than men comes from the fact that in women there are 2 X chromosomes and in men there is only one, as well as the additional Y chromosome. 

If there are any singular defects in the X chromosome a man carries, it will not be balanced out in the human male.  (other organisms have different sex chromosome schemes).  For instance because there is a cluster of genes that help the eye see in color, women's sense of color (i.e. from their cone cells) is sometimes better than men.  With 2 X chromosomes there is even the possibility of a woman who has four different color receptors in their cones. 

On the other hand, why men see better in the dark (i.e. greater sensitivity in the rod cells), is possibly due to an extra Blue Rod pigment gene that remains on the Y chromosome (see above reference).  This is both an accident of genetics, but also an adaptive 'choice' that men would have different visual acuities than women. 

Its also known that woman and men may have different epigenetic patterns, with some epigenetic modifications coming from the mother and others from the father.  This is adaptive and also not the direct result of the XY chromosomes. 

Interestingly, it turns out that for the most part women's 2 X chromosomes are mosaic.  That is, in each cell only one of the randomly selected X chromosomes are active.  Recessive/dominant X genes are often not the case.

This could result in a greater observed genetic variance for women because when you have two chromosomes, often one of the genes is completely silenced.  Women display all of the alleles of their X chromsomes, whereas men have only one X chromosome entirely, the Y chromosome being much smaller.  

So in other words, I would say that while men and women actually have the same variation in their DNA sequences, there are different patterns in the X and Y Chromosomes that might create more variance in terms of what we see in women's displayed genetic traits.
