Mother catering to determine fetal sex?

In Chinese folk have a "sour spicy female children," the reference, meaning that the mother's diet can affect the fetus's sex. But from the perspective of reproductive science sex of the fetus appears to form a fertilized egg as early as the moment of the decision by the chromosomes, with the diet in the mother's body has nothing to do. So what if the mother's diet does affect the sex of the fetus? Ancient China "sour spicy female children," whether there is some scientific basis?








The mother's diet may affect the sex of the fetus, it is scientists have found. In the trial, if given the pregnant mice were fed drugs to reduce their body's blood glucose levels, then the birth of the pups are usually female. This discovery also the traditional view - from eating certain foods can affect the sex of offspring, providing conclusive evidence.



It is generally believed that, in determining the sex of the fetus, the father's sperm and its main role, but more and more evidence that the same factors will affect the mother's child's gender. For example, there have been studies have shown that babies born to single mothers, most of the time there is his daughter.



The University of Pretoria, South Africa, Elisa Cameron (Elissa Cameron) is the person in charge of the study, she and her colleagues just want to confirm that dietary changes on sex of the fetus in the end how much impact. In experiments on mice, they fed the mice with dexamethasone (dexamethasone, steroid drugs), reduce blood glucose levels in mice.







The first three days of the experiment, researchers put the mice in drinking water the right amount of dexamethasone, after which they Youji mice fed normal drinking water. Throughout the experiment, Cameron and his colleagues repeatedly measured blood glucose levels in mice: from the average level of view, taking the effect of dexamethasone on mouse blood sugar levels dropped from 6.47 mmol per liter to 5.24 millimoles per liter. A result, the control group in the female mouse (without drugs) gave birth to 53% of the mice were male, while the test female mouse (taking drugs) left only 41% of male mice.



Why is low blood sugar can cause females born in volume? The specific reasons not yet clear, but be sure, high blood sugar also increases the amount of male births. Has there been a study showing that in rodents, high levels of glucose in the blood of the mother animal giving birth to the possibility of males higher than expected number.



Biologists believe that the above-mentioned phenomena are the result of natural selection, because the food is not sufficient circumstances (cause blood sugar lowering), more conducive to the evolution of female offspring. If you give birth to the male fetus, grow up too weak constitution would not be conducive to mating, if the birth is to female, no matter how thin, still be able to raise more offspring.



Of course, scientists do not agree with the above-mentioned experiment. Scientists at the University College London Lusimeisi (Ruth Mace), said: "blood sugar levels is not a criteria for judging health of the mother." Metz has found that when food is short, muscular women are more likely to give birth to more boys.



Food influence a child a gender perspective has long been a matter of fact. Private point of view is that if you want a boy, in relation to eat "red meat" (such as beef and mutton), or Xianla food, on the contrary they should eat fish, vegetables, chocolate and other food.



Cameron said: "This is a very interesting phenomenon, although the meat and sugar can raise blood sugar levels, but the meat for the improvement of blood glucose is a long-term effects, but eating foods with high sugar content, the in the short term will reduce the blood sugar levels. "



Conclusion: If the results of this experiment is really true, then the sex of the fetus appears to be the decision the day after tomorrow! Test-tube baby it also can change the gender out? Look forward to further confirmation of science. .
