More women would satisfy this requirement than men,
so using Grigoryev's own argument it should be
women going to Mars.

Think 'calcium loss'. I think this affects women
much more severely than men.

So now we're sending post-menopausal women to Mars?

Seriously, women don't have a higher risk of
osteoporosis until after menopause. Other risk factors
include being Asian or Caucasian, taking certain drugs,
smoking, alcoholism, bone structure and body weight,
lack of weight-bearing exercise and heredity.
