Not in my case but I did read something about this, years ago though. There were statistics on babies in distress and premies. The girls tended to be a little bit better survivor.
There have also been correlations that a vegetarian diet increases the odds of having a girl. That effect even held true for upper class white vegetarians in England. Perhaps the link is lack of meat to lack of boys. The poor are more likely to be vegetarian because they can’t afford animal protien.
