I don't know much about this field, and of course there is no conclusive discussion (because there hasn't been one of ANY neurological issue so far in science and medicine--we're still working on figuring out how everything about neurochemistry systems work). BUT it is simply not true (as suggested by JLK in a comment about Ambivalent Academic's post in response to mine) that it's all a "myth" that women experience strange and disruptive neurological symptoms as a result of hormonal changes.
Unless there was some major debunking study that I just didn't happen to find in my Pubmed search for 'hormone levels pms,' it looks to me as if plenty of people are trying to understand this and clinicians take it pretty seriously.
I haven't read Fausto-Sterling's book so I cannot comment on what evidence she provided for her apparent assertion that "PMS does not exist." But if she thinks it doesn't, she must be as fucking lucky a lady as JLK, to never have experienced these feelings of someone else inhabiting her body dictating her response to the world around her. I'd like some of what she smokes, please.
