KTK - be sure to talk to some physiotherapists about bike saddles, especially any who work with pelvic problems (incontinence, pain, etc) Find some models of the pelvis, both male and female. Sit in on a cadaver study, if you can.

Skeletally and perineally you may find that men and women are more alike than you think. The difference is in proportions more than anything.

In my experience, women don't need a different *kind* of saddle than men, they just need one that fits their proportions properly.

Manufacturers are starting to get the idea that saddles should come in sizes, like shoes, which is great. More sizes, more variety in proportions and shapes, and a clear way of categorizing them; and I think the world will be a better place.
