No it's not. I have friends in the medical community who confirmed that Jamie Lee Curtis has 100% female appearance yet is chromosomally a male. She is totally infertile. I presume (don't know) that this also means her body has no uterus and she doesn't ovulate.
Jamie Lee Curtis ... is chromosomally a male. She is totally infertile.
If Jamie Lee Curtis were truly chromosomally a male (XY), she would be presumptively fertile. As I understand it, she is neither chromosomally male nor chromosomally female --
i.e., neither XX nor XY -- but some other combination.
