Full disclosure, my baby is right now being karyotyped because there is a higher-than-average chance that he could have abnormal sex chromosomes. That's XYY or XXY.
If he has one of those configurations, he will definitely still be a male. He was visibly male at his 12 week ultrasound! These chromosomal abnormalities are specific male conditions (ones I've been reading up a lot about for obvious reasons!). XXY men are often infertile, but when there is fertility help, guess what, it's to make their testes make sperm.
If you have an X and a Y, you've got an XY. Even if you've got something else besides.
Now, there is one syndrome - de la Chapelle syndrome - that gives you an XX and (because there's an unusual transposition of the SRY gene that's normally only on the Y chromosome over to one of the X's) male genitalia. So if LM had that, LM's sex chromosomes would be XX.
HOWEVER.
De la chapelle's Syndrome is marked by the complete absence of sperm (which require more of the Y chromosome than just the SRY gene to develop).
LM has been perfectly clear before in stating that LM could produce a baby that biologically belonged to LM. In fact, LM has said so repeatedly.
Fertility is only achievable in one of the three abnormal chromosome configurations that can result in a person with male phenotype. That chromosome configuration is XYY.
If LM is trying to use an extra Y chromosome as a reason to regard LM as female, that's a laugh riot.
