How many minors (0-17) are actually getting bottom surgery to transition genders in the US?

I seem to find only one example of a 17 year old having surgery.

But so many people claim and spread the message that this is some sort of epidemic, that there are hundreds or thousands of 10-12 year olds getting bottom surgery. Am I missing something or is this a rare to non existent issue? Are there some sort of official statistics available?

I am just wondering how many millions of dollars and thousands of man hours have been spent by everyone from law makers to celebrities to force the government into private medical decisions of like 1-3 people in the US?

BTW I am not talking about top surgery or hormones, specifically bottom surgery.
