Knowing the gender of the fetus: 5 scientific indicators of pregnancy with a boy

A technique called preimplantation genetic diagnosis is the only way to ensure that the sex of the newborn is chosen, as it involves implanting a single sperm into the egg through in vitro fertilization.

While many of the proposed sex determination practices have not been proven successful, results from many scientific studies provide evidence that could indicate an increased likelihood of conceiving with more sex than the other, although the results of this follow-up cannot be taken seriously. In this report we review 5 scientific hints that the gender of the fetus was mentioned, according to a report by the What to Expect health site.
1. A high-calorie diet

One study found that eating a high-calorie diet during pregnancy and eating breakfasts regularly increased the chance of having a boy.

The researchers found that 56 percent of women who consumed the highest amount of calories at the time of pregnancy gave birth to males, compared to only 45 percent among women who consumed the lowest amount of calories.
2. Eating a lot during pregnancy

One study tracked mothers’ diets and found that pregnant women with boys ate 10 percent more caloric-rich diets than pregnant women with girls, as all of these extra proteins, carbohydrates and fats add up to 200 extra calories a day.

Researchers suspect that the testosterone hormone produced by male fetuses may send a signal for their mothers to eat more food, and this could explain why boys’ children tend to be larger at birth than girls.

3. Disgust of favorite foods

Researchers say that the more disgusted foods a pregnant woman feels, the more likely she is to conceive a boy.

The reason for this is that the aversion is related to the way a woman’s immune system works as she tries to protect her developing fetus.

The researchers say the severe allergies are designed to protect a particularly vulnerable male fetus by making the expectant mother shy away from inaccurate substances.
4. Spouses live together

Couples who live together may be more likely to have children than single mothers, as one study looked at 86,000 children born in the United States between 1959 and 1998.

The study found that 51.5 percent of women who had been with their husbands before pregnancy had given birth to children, compared to 49.9 percent of women who were not with their husbands.
5. Gestational diabetes

Some research has found that expectant mothers are more likely to develop gestational diabetes, a pregnancy with higher than normal blood glucose levels – than expectant mothers who carry daughters.

Researchers are not sure why a fetus might lead to greater pregnancy-related metabolic changes than a girl’s fetus, but these results seem to be supported by more than one study.
