"Chimerism in a woman with a 46,XY karyotype and female phenotype," Human Reproduction, 2001, 16, 56-58.
"Demonstration of spontaneous XX/XY chimerism by DNA fingerprinting," Human Genetics, 1989, 82, 197-198.
I didn't read the second article (published too early to be online) but the first involves a woman with a normal reproductive system but some of her tissues have XX cells and some XY. She had a baby at 17 and was seeing the doctor because of infertility (unrelated). This article references the other case and says that in that case the woman had XY cells identical genetically to her twin brother's. They don't say if she had children, but said she was phenotypically normal.
The article I'm looking for is even more interesting because the woman had one normal ovary and the other had a mixture of XX ovarian and XY testicular tissue.
