The only way to 'nudge' the chances of a girl baby is to select the sperm based on which sex genes they carry. Any hormonal or such changes induced in the fetus down the line is too late to have any effect on genetic gender.

I would suspect, though I haven't seen any studies, that some fertility treatment steps unintentionally have mass-sorting properties similar to the barrier diffusion Uranium enrichment technique used in the Manhattan Project.
