Many young couples have their own expectations for their future child before becoming pregnant. The father wants a son to share his passion about sports and speed. While a lot of mothers want a little angel to put on lovely princess dresses. However, the sex formation of the fetus also depends on many factors. So what factors determine the sex of the fetus? Along refer to the article below to know more.
What does the sex of the fetus depend on?
According to research, in the body has 1 pair of chromosomes in 23 pairs helps the doctor can recognize the sex of the fetus. A pregnant woman, a boy or a girl, depends on the father's sperm. the daughter's chromosome pair.
If sperm carrying Y chromosome combined with oocyte carrying X chromosome of mother will form pairs of XY chromosome, it is son's. So whether a boy or a girl is due to the father's sperm carrying the X or Y chromosome.
Factors determining the sex of the fetus
Age
The number of male sperm will decrease with increasing age, so the probability of giving birth to a girl becomes greater, this is a proven fact. Likewise, as an older woman reduces the amount of alkalinity in the uterus, the chance of giving birth to a girl increases. Therefore, young couples tend to have a boy because their physical health and fertilization environment are very favorable.
Breakfast
A recent UK study has surveyed 740 pregnant women about what they ate before becoming pregnant. As a result, those who typically ate a cereal breakfast, calorie and potassium-rich foods were more likely to have a son. On the contrary, people who often skip breakfast have more girls.
Weather temperature
According to Livescience, Japanese research shows that climate change can affect the sex ratio of a human fetus. Scientists have found that male fetuses are more vulnerable to the effects of climate change, particularly when the weather warms.
In addition, researchers from Ben-Gurion Negev University (Israel) and Harvard (USA) have also shown a relationship between air temperature and infant weight . Specifically, the mother's exposure to high temperatures during pregnancy increases the risk of having a baby with a lower weight than normal and more likely to give birth prematurely.
Posture "love"
The X chromosome carries sperm that is larger and lighter than the Y chromosome. This also means that lighter sperm can meet eggs more quickly. This may be the reason why many people believe that applying a certain position can cause X or Y to "swim" to the egg more quickly.
According to Webmd, traditional posture (male upper, female lower) will make it easier for you to have a girl, while the male "attacking" position from behind has a higher rate of male births.
The "little girl" environment
Some studies show that the vaginal environment can also partly determine the sex of the fetus. Specifically, the alkaline environment helps increase the proportion of boys because Y sperm are susceptible to damage in an acidic environment. Therefore, an acidic environment is more likely to have girls.
To increase acidity, you can clean the "little girl" with water and vinegar, and water combined with baking soda will create an alkaline environment, making it easier to have a son.
The moment of "love"
Choosing the time when the egg is ovulating to conceive is also a popular way to determine the sex of the baby. Accordingly, if you have sex near the day of ovulation, you will have a son more easily. And "love" far from this point, the rate of having a girl will be higher.
