Gendered trauma?

According to some recent research, what is often thought to be postnatal depression is actually post-traumatic stress disorder.

Without going into the merits of the argument (I don't have the necessary medical understanding), beyond an emphatic agreement that birth is traumatic, I can't help but wonder about the implications of the theory. Put this down to my recent reading of Superfreakonomics, but I do suspect that there is more funding out there for research on PTSD, given its associations with war, violence and other more 'manly' pursuits, than on PND, which is clearly a more feminine affliction and still relatively widely thought to be just part of a natural process. Could the traumatic experiences of parturient mothers be taken more seriously or have more support services directed towards them if they were framed in the same terms as those of soldiers?
