It depends what you mean by abroad. Thailand seems to have quite a lot of expertise in these surgeries so many people go there. They tightened up their regulations a few years ago after a mum took her 16 yr old for the penile inversion/vaginoplasty- it is now strictly over 18s.
Many Children’s Hospitals in America now market their surgeries to minors - mainly the double mastectomy (I think penile inversion/vaginoplasty is limited to 17/18 yr olds) - which in some states is fine as young as 12 and 13. Some of these hospitals do not offer any counselling or therapy they will just recommend puberty blockers and surgery, often at the first appt for gender confused children.
One surgeon in the US markets her services to minors using groovy Tiktok videos, dancing around talking about ‘yeeting the teets’ and also operates on morbidly obese patients that have been refused surgery elsewhere.
One patient went public recently as she nearly died from sepsis and complications (6 inches of necrotic tissue and a gaping hole) due to this doctors actions and lack of follow up support - the doctor was very flippant when she requested advice. This doctor appears to have performed surgery on thousands of young people.
To save money some go for the nipple free option where they end up with a large scar across their entire chest. As their bodies were still growing we have seen instances of this scar stretching vertically and creating an inch wide jagged line across the chest.
This is happening to teenage girls who are too young to get a tattoo, drink or have sex.
