If they have a Y chromosome they are male. It's not a theory it's a fact. They presumably have some abnormality which means their male-ness hasn't been expressed. All will be infertile.
The "abnormality" for the first two is that their testicles failed to develop, so their prenatal development took place in the absence of testicular hormones. The third one does (or did until the NHS butchered her) have testicles which did produce testosterone throughout her prenatal development, however she has a mutation to her gene for the androgen receptor, which means the cells throughout her body are completely unresponsive to testosterone and other androgenic hormones. As a result, all her prenatal development took place as if those hormones weren't there. Since all 3 people have developed as female not male, that shows it's not the Y chromosome that makes a person male, but androgenic hormones produced in the testicles.
Just to drive the point home, there is a condition called De La Chappelle syndrome, which causes genetically female (XX) people to develop testicles instead of ovaries. These people develop as male despite being XX. I guess since their chromosomes say XX you'd be happy to welcome such people into your women only spaces, penis and all!
I should also point out that the women in the first two videos were born with the full set of female internal organs (apart from ovaries). Through donor IVF and with appropriate hormone treatment to grow their uteruses to adult size, they can fall pregnant and give birth.

Are these women not intersex then?
Medically they're classified as intersex because they have XY chromosomes and aren't male. However, there's no hint of masculinity to them, they're not in between male and female, they are fully female people. It's an example of how the doctors who came up with the system for classifying abnormalities of sexual development, didn't actually understand the biology of how sexual development takes place.
What medication affected you HugeE?
I don't know for sure. I've got many of the same symptoms that seem to commonly go with DES exposure in natal males. I was born with a hydrocele, one of the genital abnormalities that often seem to occur in DES sons. I have a "eunuchoid" body structure, another thing that commonly seems to go with DES exposure. I experienced the same pattern of very shy, socially withdrawn behaviour as a teenager that was commonly seen in teenaged DES sons. In my 40s, the subclinical hypogonadism I've had all my life abruptly became much worse, and I got sick with all the typical symptoms of acute hypogonadism. This is another thing that commonly seems to happen with DES exposure (and I think may be the deciding factor for many late transitioners who've been sitting on the fence up until that point).
On the other hand, my mother had no prior history of miscarriage, nor (according to my dad) were there any medical problems during the pregnancy that might have led to DES being prescribed. There's also the fact that nearly all the DES exposed "males" I've talked to identify as women, whereas for me it's very much a case of not really being male or female, but kind of a mixture of the two.
Especially when I was younger, my mother used to suffer from depression a lot, and I can remember some quite outlandish behaviour from her (throwing things at my dad, smashing stuff etc). Looking at the parts of my psychology that appear to be female, whatever happened to me must have happened very early in the process of wiring up the permanent structure of the brain (which starts around 16 weeks after conception). That's also just around the time a pregnant woman will first feel her unborn baby moving around inside her.
The thought I had was, perhaps my mother was in a depressive state during her pregnancy with me, and when she felt my first kicks, instead of being overjoyed, she decided that she couldn't cope with another baby so soon after the first (she fell pregnant with me just 3 months after my brother was born), and took an overdose of something in an attempt to terminate the pregnancy.
I did a bit of snooping on some maternity forums, and the first thing most unhappily pregnant women looking for a DIY way of ending the pregnancy seem to think of, is an overdose of birth control pills. I was able to establish that they were using birth control pills for contraception at the time she fell pregnant with me (the first generation high dosage ones), and there's something otherwise inexplicable that happened later in my childhood, that makes me think she could have been hiding a guilty secret along those lines. But I'm unlikely to ever know for sure. Both parents are now dead, and the chances of medical records having survived from a pregnancy more than 50 years ago are remote to say the least.
However, if that is what happened, then it opens up an enormous can of worms. It means that other synthetic hormones besides DES can also interfere with male development, including those in the oral contraceptive pills that 150 million women worldwide use every day for contraception. Furthermore, although the birth control pills my parents used contained a small amount of estrogen (ethinylestradiol), their main component was the progestin norethisterone acetate. This would mean that it's not just estrogens (such as DES) that can interfere with male development, progestins can too. In most places, DES, and all other estrogens, had been withdrawn from use in pregnancy by about 1980. Progestins were never withdrawn though, and some are used during pregnancy even now.
Perhaps you can see why I've been trying to alert people to what these drugs are capable of doing? It's bad enough when it was just DES, but if what I think happened to me is correct, then the entire gamut of hormonal contraceptives and progestin-based miscarriage treatments can do the same thing. That would explain why more and more trans kids continue to be born, even though DES was phased out 40 years ago!
