I think its somewhat related to the soceity presentation of men. Appear as hypermasculine, superiority to feminism, and show no "Weakness" this is very prevalent in western society. An example would be a 6ft+ tall muscular male, blonde, blue eyes, with no defects or disease and very well off individual, thats how the world views males. And males in general dont like to go to the doctor,because of this. I see alot of males of this type at my school who are like this, always muscular or acting very masculine, into the whole "fitness,bodybuilder, or powerlifting" fad. It is good to keep a healthy body, but these are designed to be a way to show off thier psyche and masculinity. theres a video titled"mens standard of beauty around the world" on youtube. They describe how masculine, mostly white males are attractive. around the world.

skimmed the article, it is implying that some autoimmune diseases are more severe in one sex than the other, and vice versa. Also the ratio is not very clear cut, as they ONly refer to ADULT MALES in this article, so its not really accurate, because it does not include younger males, also the age of the females,pregnancies, also needs to be account. it is also not clear about the ratio, because there are so many autoimmune diseases out there, some like lupus,ms are known to be more predominant in females. This article only goes for highly industrialized countries, like the west, China and india is included. Furthermore, CHINA, india and USA have a much larger population, which includes immigration, so you would expect more autoimmunes to be happening than in the smaller european countries.
This is kind off topic from the OP, but he should only see a rhuemy if a autoimmune, or connective tissue disease is suspected.
