ANOTHER SEXIST CALUMNY EXPLODED BY SCIENCE! Man flu is real because oestrogen protects women from the influenza virus. “New research has – once again – appeared to prove the existence of the much-contested ‘man flu’. The study, published by researchers at Johns Hopkins University, suggests that the female sex hormone oestrogen could help women combat the virus, leaving lesser-protected men out in the cold. Oestrogen, which is found at considerably higher levels in women than in men, was found to reduce the replication of the ‘influenza A’ virus in nasal cells, thereby initiating antiviral effects against the disease.”
