Fox News host Elisabeth Hasselbeck learned on Monday that different foods and different workouts could not change a baby’s sex after conception.
During a segment about “babymaking fact or fiction,” Dr. Nancy Simpkins explained that a recent study showed that diet before pregnancy could influence the sex of the fetus.
Researchers concluded that skipping breakfast increased the chances of having a girl, which they said could partially accounted for the declining birth rate of boys in the western world.
“The Y chromosome likes a higher glucose environment,” Simpkins pointed out, adding that workouts with a lot of cardio also lowered the chances of having a boy.
“To clarify, leading up to pregnancy?” Hasselbeck interrupted, sounded genuinely confused about whether a fetus’ sex could be changed after conception.
“We’re talking during the time that you’re trying to conceive,” Simpkins clarified.
“Got it,” Hasselbeck replied in astonishment.
In fact, the sex of the child is determined at the time of conception, when the X or Y chromosome from the sperm cell fuses with the X chromosome from the egg. Boys will have both an X and a Y chromosome. Girls will have two X chromosomes.
