when the government reviews the gender recognition act 2004 (which they've promised to do in 2018), all of that dysmorphia verification stuff is expected to be swept away. all that will be required for gender reassignment is a self declaration, and hey-presto, legally regendered, no surgery or intrusive medical questioning required.
not sure if someone who is born X-Y and is legally female by virtue of self declaration would be accepted as such by the International Sports organisations - there might be some aspects of what's being proposed that the government hasn't thought through yet.
