Reminds me of an interesting thread from 2018 that had both Barracker and Bowlofbabelfish.
The idea that all of these disparate conditions somehow are part of a community is a myth, I think.
There's no reason really why a woman with Turner's syndrome should feel she has any commonality with a man who has Klinefelters. They are completely different conditions affecting two different sexes, with entirely different health implications.
Dragging them under the same banner simply because they are disorders of sex development is as pointless as telling me my cervical smear gives me commonality with a man's prostate exam because they both involve stuff below the waist.
The term intersex is being used as political collateral by those with an agenda, and not only does it make no sense, it isn't with the consent of the people it relates to.

Somewhat in line with the discussion there, there's a nuanced argument for not including Klinefelter fully in the category of DSDs.
One of the most common chromosomal abnormalities is found in XXY Klinefelter syndrome (NHS, 2019). Whilst technically not a DSD, this condition illustrates the female-male interface further. Males who are born with an extra copy of the X chromosome develop small testes, shortage of testosterone, low muscle mass and enlargement of breast tissue (gynaecomastia). While typically infertile, some men with Klinefelter are fertile; they produce sperm and father children. When a male body fails to fully masculinise, it does not develop reproductively into a fully female body instead, because the male and female pathways are not interchangeable.
