Is 'man flu' a real illness?
Evolutionary factors and hormonal differences may make males more susceptible to infection than females, says a Cambridge University team. However, a leading flu expert says there is no difference in immune systems between men and women.
Previous experiments by the Cambridge team have found differences in the ability of females and males to deal with infection. High testosterone levels, they say, lead to more coughs and colds.
Could evolution make men more prone to coughs and colds? Are you a man who takes a long time to recover from flu? Do men suffer from flu more than women? Do women complain more than men?
