This is essentially correct. Sexual differentiation in humans occurs
around the 6th - 8th week of gestation. Before then all fetuses
contain both male and female reproductive organs and tracts. In the
absence of the Y chromosome, the male tract regresses and the female
I teach my students that we are all born to become female. Only the
presence of the Y-chromosome will stop the inevitable. :-)
