Quote:

these guys need to go back to high school health class. the female has absolutely no control over and no input in whether the baby she carries is male or female. all eggs carry the X chromosome. it's the sperm that carry the X and Y chromosomes. gender of the baby is determined at the moment of conception, based on whether the egg is fertilized by a sperm carrying an X or Y chromosome.

it wouldn't matter one whit what the mother ate before or during pregnancy. we aren't alligators where the environment surrounding the offspring has an impact on sex.

I can see how it may be possible - the environment the sperm travel through and/or the thickness of the outer layer of the egg it must penetrate may be such that an X or Y sperm becomes favored to "win" getting in to fertilize the egg.....or it could be viability of the XX or XY embryo that is the determining factor of the fate of the outcome - if the environment is favoring one way or the other, an embryo may be spontaneously aborted before the woman knows she's pregnant and then that would skew the percentages of boys vs. girls born over time.
