This poor bloke who found out he was infertile during a premarital medical exam, for instance: https://pmc.ncbi.nlm.nih.gov/articles/PMC7760426/

Have you heard of the politician's fallacy, "something needs to be done, this is something, so this needs to be done"...

Your argument here is that... needing a test, and having a test, doesn't mean it's the right test.

You're also assuming that we even need a test... evidence (no transfemale olympians ever coming not dead last) suggests we don't.

it doesn't really do anything after puberty

it's about gene expression and it can be discarded genetically

so yes there are "men" walking around who would show negative on a SRY test and qualify

again, they tried this exact thing in 1996

and it went over so badly they ended it by 2000

this is 100% politics and conservative people with power trying to manipulate things

biology is not binary, it's messy and not exact

there are "common" things and less common

Another approach would have been to accommodate the less common

But you'll notice they didn't even try to do that
