Each woman lives transformations your body differently and those around not hesitate to assert the most ridiculous theories. So, get statements like "if cutest is because it leads to a male in the belly" or "if your belly has a rounded shape will be a girl." both move away from what is happening in reality: every pregnant and fundamentally happy woman, looks extremely beautiful (is it the same symbol of life), beyond the sex of your baby, and your tummy swaps responds to position small adopt within her womb.

Nor weaken teeth, as some claim, since calcium has is enough. If the doctor were to consider otherwise, give more. Nor is it necessary to eat for two, that will only increase the risk of developing gestational diabetes. Finally, it is permissible to take a dip in a pool and, if possible, to have all the sex you want, unless the doctor says otherwise.

Those are some of the myths circulating on the Internet and word of mouth. Find out the rest here:

Myth: You can not have contact with cats

Have you told your mother? Well tell that toxoplasmosis virus-scientific-popular name of fear spread through feces and if they are infected. So if you have a kitty at home, just take him to the vet for quarterly deworming and someone else takes over the pebbles change.

Fact: The hormonal changes occur in the mother and the father

That maternal hormones were agitating and change their levels in an amazing range is not new. However, according to a study published in Evolution and Human Behavior in 2000, the paternal hormones also be modified during pregnancy.

The levels of testosterone in a man who is expecting a child decrease as well as increasing their levels of the hormone prolactin, which in women is responsible for the formation of milk. The researchers suggest that these adjustments the body could help men to become fathers.

Myth: The shape of the skull determine sex

This theory, fashion blogs babies were probably created by the number of scans that have pregnant. For experts, however, it is completely impossible to determine if it's a boy or a girl depending on the size and shape of the skull.

Anthropological studies have shown that men tend to have larger and more massive skulls, while women are more rounded and delicate. The forehead is more prominent in men and is more square chin. All of these features, however, newly acquired puberty.

87 percent of reality: You can choose the sex of baby food

According to the theory of Dr. François Pope and journalist Francoise Labro, 1984 could scientifically prove "the influence of maternal nutrition on the sex of the child to be born" on the balance of certain minerals and their effectiveness would be 87 percent. So Adriana defends biochemistry Baretta, which updates the method and promises a 98 percent guarantee.

While there is a margin of failure, the balance between sodium, potassium, calcium and magnesium in the body of women before pregnancy could determine the sex of the baby.

Progesterone hormone reigns in most of the pregnancy, the female stimulates the respiratory center to increase oxygen consumption and can release more carbon dioxide, and the self that is generating the baby. Also, because pregnancy limits the expansion of the diaphragm, the respiratory muscle, than the frequency is increased to compensate.

Although this may slightly unbalance the body gases, no disturbances in the acid-base status are generated, since pregnancy is a physiological state of the body.

Myth: If you do not fulfill a craving, your child will be born with a stain

Scientists agree on something: birthmarks have nothing to do with cravings. But fail to agree on the following: cravings correspond to what your body and your baby need.

"No one knows why cravings occur, one theory is that they represent the nutrients that are missing mother and maybe that's the way for the body to ask for them," said Andrei Rebarber, associate director of the division of maternal fetal Medical Center NYU . Experts recommend that you listen to your healthy cravings and try to replace those who are not with emotional support, exercise and eating breakfast daily.

Myths and realities are infinite. An Aztec belief holds that if a pregnant look at an eclipse, your child will be born with a split lip, as it represents a bite on the face of the moon. Cleft lip is given by a mixture of genetic and environmental factors, so if it is known that the myth is false, just in case, better care to pregnant eclipses.
