Fun fact...many cis woman have microchimeraism where some of their chromosomes are XY-
From
Fetal microchimerism and maternal health during and after pregnancy.
Pregnancy is another source of microchimeric cells, implicated by studies in women identifying Y-chromosomes from a male fetus. Male and female fetal cells cross the placenta in equal numbers, but studies of microchimerism rely on the demonstration of the Y chromosome as proof of principle.
Fetal microchimerism is defined as low levels of fetal cells harbouring in maternal blood and tissues during and for years after pregnancy. It has been proposed as ‘a state of balance between host versus graft and graft versus host reactions, leading to the acceptance of the allogeneic fetus’.
10 Presumably, the placental immune suppression that is needed to maintain the allogeneic pregnancy also helps establish microchimerism. This immune suppression of pregnancy may remain for several months after delivery, allowing persisting fetal cells time to establish themselves.
3 All parous women thus become chimeric.
@JustGeorge for example is a ciswoman has had male kids. Its possible she could be a microchimera without knowing it. It's not something many people test for. It dont really affect health from my understanding. It's unknown how common this is but considered to be very common. If she is would that make her less of a woman?
