If the Oxford dictionary defined the term man flu as "a cold or similar minor ailment as experienced by a man who is regarded as exaggerating the severity of the symptoms", the Man Flu website explained it to be "a crippling and debilitating disorder indiscriminately striking down male members of the human species without warning".
She said: "We're sorry to be the bearer of disappointing news for half the population - but contrary to popular belief, and this article, the vast majority of robust scientific evidence suggests that flu is not sexist and there is no such thing as "man flu".
It's also shown, with many respiratory diseases, men are more susceptible to complications.
The British Medical Journal's December issue is meant to be a special issue that has peer-reviewed articles, but allows authors to use some humour, said Navjoyt Ladher, the editor who put the issue together.
GETTY EVOLUTION A new study shows that men evolved to have weaker immune systems from women
Sue, a clinical assistant professor at Memorial University of Newfoundland in Canada, set out to determine whether men really experience worse symptoms than women and whether this could have any evolutionary basis.
The so-called "man flu" has been a punchline for decades, but according to one expert it may be time to stop taking it lightly. According to a Canadian doctor, men flu is actually a real health condition.
So, it's no surprise that men often end up the subject of good-natured ribbing, in the form of so many Internet memes. Meanwhile some evidence supports men suffering more from viral respiratory illness than women because they have a less robust immune system. He added the evidence suggests that, overall, women may be "more responsive to vaccinations than men".
Sue's study also considered the hypothesis that the hormone testosterone may have a relationship to influenza by acting to suppress the male immune system.
Sue points to still more research that suggests men's increased sickness may be a survival instinct since "it promotes energy conservation and reduces the risk of encountering predators".
