Non-consensual genital modification generally occurs at birth, and in all Western countries is strictly limited to male circumcision. I am not sure, but I don't think you could have your 12 year old circumsized against his wishes. So this bullet point is a bit exaggerated.

There is another circumstance in which this applies. Intersex infants with ambiguous genitalia are often surgically modified to better match one of the two standard genders. (But, yes, I admit that the bullet point is exaggerated.)
