In Swyer syndrome they are genetically male (Y chromosome) but the testes don't develop properly and instead they develop female characteristics, sometimes including a uterus. However, they don't produce ovum like females so they would have to have an egg donor and hormone treatment but could theoretically get pregnant through IVF. That's how I understand it, at least. Even though they're genetically male, they're almost always brought up female due to their characteristics and genitalia. Sounds like a difficult life, it's a shame they get lumped in with fetishistic freaks who use them as pawns.
This is quibbling about terminology, so it's not super productive, but I wouldn't describe individuals with Swyer syndrome as "genetically male".
The reason being, the Y chromosome triggers male development because of one specific gene on it, SRY.* Not really the whole chromosome.
When DNA gets copied, if the SRY gene gets fucked up and is nonfunctional or missing, the individual develops as female (that's Swyer syndrome). Or sometimes the SRY gene can get copied to an X chromosome, so you get XX males.
There's other genes on the Y chromosome that aren't strictly sex genes, but the effects they cause are almost always found in males for obvious reasons.
And in reverse, males aren't supposed to have two X chromosomes, so XX males have a lot of side effects, even if they still have the essential male development gene, SRY. (Or like how XXY Kleinfelter patients have a lot of side effects from their extra X.)
I think it might be more accurate to say someone without a functioning SRY gene is still "genetically female", even if they've got XY chromosomes.
But in general, I don't like the practice of subdividing sex with terms like "genetically male", "hormonally male", etc, etc, because it feeds into troon arguments.
Like if a woman has high T naturally or due to something like PCOS or whatever, perhaps scraping into traditionally male ranges, the troons will want to describe her as "hormonally male", instead of what she actually is, a female with a disorder.
But yeah, this is just quibbling about terminology, so not super important.
* And if you really want to get into the weeds, there have been examples of SRY-negative individuals who still develop as male. There's some niche genes that seem to be able to step in for SRY in a pinch, like SOX9. That's an extremely rare anomaly of an already rare anomaly.
