> That implies a woman's reproductive system knows and remembers or at least keeps a tallies of the sex of the offspring it has produced...
It doesn't require a tally, it just requires that the body stores something that correlates with number and gender of previous children. Like, say, indefinitely retaining genetic material from each of them. Which, you know, mother's bodies do:
“Not only fetal cells, but also fragments of fetal DNA can be present in the maternal circulation indefinitely after pregnancy. This finding has practical implications for non-invasive prenatal diagnoses based on maternal blood, and may be considered for possible pathophysiological correlations.”
