Genetic distance sex differences?

Looking over the genetic differences reported by the Marshfield web
server (, there's a huge difference
between male and female cM distances for STRP markers.  Why should this
be, and doesn't this imply that genetic distance varies widely between
individuals?  Other database servers only report one number, presumably
the sex averaged number.  Does this really give a useful map that can be
applied to numerous samples in mapping?
