Unfortunately his suggestion is that people declare what they were born with, which is not feasible as most people can't remember their birth. A significant minority of people have surgery soon after birth which changes what they were born with. Some of those are not told this, and therefore do not even know the information he says is needed.
Also, his chosen physical factor isn't directly linked to size and weight. Testosterone levels, which is what sport seems to be settling on as the discriminator (not without controversy), are. Much as some feminists see the penis as the oppressor, it appears that in reality it is the cojones that maketh the man (or at least the person not allowed to compete as a woman).
Still not a good question to ask, as some people don't know they've got them, but happily we can just give every passenger a quick blood test to find out...
