Does a woman retain traces of her male partner after giving birth?

Nope – still doesn’t count. The question wasn’t, “Does pregnancy have any permanent effect on a woman’s body?” Of course it does. But those Rh antibodies[ul]

I thought the question was “Does a woman retain traces of her male partner after giving birth?”.

Are you suggesting that the baby (and thus its genetics) isn’t a direct consequence from a particular father, ahem, “leaving his trace”? Sure, luckily, the father’s residual immunochemistry won’t have any genetic effect on subsequent children. It “only” may cause the next baby to die. And since the entire baby comes from the woman herself, after all, this can’t possibly have anything to do with the first father, eh?

It’s not just a permanent effect left by pregnancy, it’s an immunisation against a specific type of antigens, depending from a particular father. Anyway, it’s likely that you’ll find fetal cell lines remaining in the mother. Half of their genetic information comes from the father. One father’s effects differ from another. You can tell one father apart from other men by identifying the changes they caused in the mother. I call this “retaining a trace”.
