"Men really do have an excuse for supposedly being wimpy about coughs and colds - their immune systems are not as strong as women's, research suggests.
A Canadian study indicates that the female sex hormone oestrogen gives women's immune systems added bite at fighting off infection. Oestrogen seems to counter an enzyme which blocks the inflammatory process.
The McGill University study appears in Proceedings of the National Academy of Sciences.
The researchers focused on an enzyme called Caspase-12, which is known to put a brake on the inflammatory process, the body's first line of defence against harmful invaders such as bacteria and viruses. "
Yet another reason not to over do your estrogen suppression ?
