I've always been quite wary of pointing out biological differences between males and females in the human sexually dimorphic species, because they've been used historically as a stick to beat women with.
So this finding could be used to argue that gastroenterologists would benefit, during their specialist training, from a more detailed knowledge of female-specific small intestinal morphology and function (and how important it is to relate that to female endocrinology across the lifecycle, as pp have noted above).
Unfortunately the socio-political structures in which we live allow for an argument to be put forward that this new study confirms women's natural reproductive function and therefore that means it's 'unnatural' for them to have careers. Well, you all know the arguments. Women, know your limits! and all that.
That's why women in Victorian times had to change their bloody names to get a book published and taken seriously.
