Oh I think there is a huge gulf separating the sexes. But the perceived bias may not just be bias... could be ignorance (I am referring here to medical ignorance). And it is not all one-sided. Try going to doctor when you are a male with downstairs (euphemistically speaking) issues. A lot of males with ME have urination, testicular dysfunction, pain, performance issues. There is not much info on the web about these issues and what is is mostly hearsay. I think what I am trying to say here is that for males and females there is major bias, social conditioning etc which makes it difficult for us. And of course you have the old chestnut: women want to talk about a problem, convey their feelings. Men want to solve the problem, not share their feelings. If the problem can't be solved eg in the case of ME in the doctor's surgery, then the male doctor is placed in a difficult personal situation. Nothing in his little pigeon holes fit, except maybe hysteria and whinging.
