I have Rachael jones looking over my shoulder as i type so this is from a male and female perspective. Oh and rachael is a top pyshio and looking to train as a doctor.

Repeated blows whether cushioned or not can lead to tissue damage. Head guards can and do mask real damage. Might this be the case for chests? Its probably worth noting Rachael is'nt the heaviest of women up top and wears no protection.

Having sustained groin damage from a knee straight in the sweets I confess I dont see the arguement. A mans groin is by far more fragile than a womans chest. But ultimately it is for the fighter to decide.

Though there should be a distinction between chest protector and chest, abdomen, shoulder protector. For example I have the simple and effective thai style groin protector and the old fashioned boxing style gaurd that restricts leg movement but completely protects the groin, hips and abdomen. My point is that it this is the fight game. and pain and pyshical injury is our calling card.

And with the exception of Dr Choudry I have never met a Doctor than agrees with the fight game and Ive met lots professionally!!
