We have no clear data on how many trans people choose private routes for gender-affirming surgery—whether in the UK, elsewhere in Europe (with Spain, Turkey, and Belgium being popular destinations), or, most commonly, in Thailand. This data gap is not minor; it represents a structural blind spot in how health systems record—or fail to record—private medical procedures.

No country collects comprehensive statistics on private-sector gender-affirming procedures. Even countries with robust public health systems, like Belgium or Spain, do not require private hospitals to report procedure-level data. Thailand, arguably the world’s leading centre for gender-affirming surgery, has no national reporting requirements at all. As a result, most gender-affirming surgeries worldwide are happening privately—and remain statistically invisible.

This invisibility matters because public-sector numbers are often mistaken for the whole story. When anti-trans commentators claim that “only a small number of trans people have surgery,” they are either unaware—or, in the UK context, more likely deliberately distorting the facts to support a hostile trans agenda.
