From the University of McGill in Canada this week there
has come a report that a research team under Dr Jeffery Mogal that mice are
repelled by the smell of men but indifferent to that of women.

A Journal called Nature
Methods
published findings that men repel mice or even worn clothes with
seat remains repels them but women do not affect mice at all.

Men cause mice to produce increased levels of
corticosterone, a hormone that increases when the mice are stressed that tend
to enable them to bear pain during troubled times. Mogal and his team hold that mice and men
share pheromones such that it could be that the smell of a man might be taken
for many hostile mice. This phenomenon might involve women revising many experiments
done by men if ever the earlier results seem to be affected by the difference of the human sexes.
