women who don't have periods are... wait, for it, women. and thus adult human females.

your blood has the DNA of your male donor because of the marrow transplant. still doesn't make you male or a man. if you wan't a label it would be Chimera. lol.

Our blood cells need to be replaced constantly (this is why a blood transfusion only temporarily changes the DNA profile of our blood). What this means in a bone marrow transplant patient is that his or her blood comes from the donor's stem cells. And so has the donor's DNA.

It is possible for women to have male DNA in their bodies, and it's often because of pregnancy. In the 1990s, scientists first discovered that, during pregnancy, a woman and a fetus can trade a small number of cells. In some cases, these swapped cells can be detected decades later in both mothers and offspring,

The basic idea here — that you can have another person's DNA inside your body — is not BS. It's known as chimerism, and it can happen in a few different situations — like in people who get bone marrow transplants. The term comes from "chimera," a mythological fire-breathing creature with traits of a lion, goat, and dragon.
