Is There a Single Biological Determinant for Womanhood?

A, there really is no such thing as a singular biological determinate for womanhood. A, the actually have been scientific studies on how there were women who gave birth and lived their whole lives. So even if they have an x y chromosome, a set of chromosomsa, they developed female characteristics and even gave birth. And so i just want to put it out there that even on the level of biology, it just does not make sense for us to tie the definition of womanhood to that.
