This Has Been Studied Before
Chimerism from bone marrow transplants has been studied previously. In 2004, Bone Marrow Transplantation found that marrow transplants replace at least some of the patient’s blood DNA. Even blood transfusions can temporarily replace DNA in the patient’s blood. However, these research solely examined DNA alterations in blood. Prior to the Chris study, scientists had not investigated how a patient’s DNA changes throughout their body. In this regard, his situation defied all expectations.

He also stated that if Chris’s donor were female, it would not transform him to the feminine sex. “It doesn’t matter,” Dr. Rezvani replied simply.
