It’s just wild that we remove sexual organs -which is irreversible- from those who aren’t sexually mature yet, rather than relying on therapeutics that are reversible until they’re of age. Especially since so many trans youth also suffer from other mental heath issues. Those issues at least should be looked into and treated prior to moving forward with organ removal.
There aren’t really studies targeting below 18 individuals because it isn’t the standard of medical care.
This is an excellent look at the Oregon Health and Science University. They had 6 individuals out of almost 2000 who sought reversal. 5 of those were not their original patients so did not go through their pre surgery procedures.
This is a systemic review looking at others research into this topic that finds a slightly higher but similar level of regret, around 1%.
