If your refering to women having ONLY XY as their sex chromosomes then I'd say that is very impossible! because XY chromosomes determine the male of our species.

Yes it is possible...even though XY chromosomes are for males only...
e.g
Say that a fetus with XY chromosomes is in the early development stage(2-3weeks)..normally the XY would indicate that it is a male.
However very rarely the DNA structure can change from being a male and becoming a female(but the XY chromosome stays the same)
so the baby ends up being a girl with XY chromosomes...this doesn't mean that she is weird or anything she just acts as a normal woman would
a situation in the 1950s i think....a few women in a sporting competition had a blood test to make sure that they were female and a few of them ended up being "male" simply because they had the XY chromosome

Folks with androgen insensitivity aren't really women. They have testes, not ovaries, so breast development not withstanding, they are men.
However, there are some people born with an X and Y, but a small piece is missing from the tip of the Y chromosome. This location houses the genes that determine gender in humans. If male determining genes are absent, the offspring develop into the default sex: woman. Since the rest of the Y chromosome is present, these inviduals are usually more "normal" than women born "XO" with onlt one sex chromosome.
Sorry, but THIS is the "correct" answer.

That would make them a man.
Occasionally there have been a few people with XY chromosomes who were mistaken for females at birth because their genitals did not develop right. But they are not females with XY chromosomes, they are males who were mistaken for females.

No. They determine gender by the person's chromosomes.
If they have XX that's a guy and XY is a woman. Even she looks like a girl. She's actually a boy if she has XX(only scientifically)

Yes - it's called AIS

What's more, there are also XX men:

no if you have a y your a guy... i think theres a condition when the person has YY chromosomes though i'm not sure what its called.

Edit: I didn't describe it very well. It's an intersex condition.
