In the womb times two…
Girls are born with all their eggs, and so a pregnant woman who is having a girl is also carrying half her grandchild.
Now, from what I’ve read before about stress, heavy stress like living in a war zone can produce so much cortisol than it affects the unborn child. Given this, I suspect this could also effect a soon to be born girl’s eggs too!
It's been shown that heavy stress in children can modify the glucocorticoid receptor gene which your brain uses for stress response. The study of this phenomenon is called Epigenetics. It's pretty intuitive once you go one layer deep: stress itself does not change your genome, but stress triggers a hormonal/chemical response which does.
