With the changes of the times, China's traditional "son preference" thought is gradually fading away. For example, many young couples now say that boys and girls are the same, and many families prefer boys to girls, but this does not mean that the birth rate of girls has increased.

In recent years, authoritative statistics show that the birth rate of boys in China is still higher than that of girls. Let's not talk about big data. Just look at friends and family around us. It seems that there are more boys and girls. Not long ago, a friend teased me. In the future, with more men and fewer women, it will be more and more difficult for boys to find wives.

But the imbalance between men and women is only from a macro perspective, and whether there are regional characteristics cannot be generalized, understand? There are many male babies, which may be related to the following four reasons, which is quite interesting to say:

1. Climate warming makes chromosome activity stronger.

With the popularization of science, we all know that it is father, not mother, who decides to have boys and girls. The sex of a child is determined by chromosomes. Y stands for boy, X stands for girl, and there is only X in a woman's egg. The chromosome contributed by a man's sperm may be X or Y. If it is XX, it is a female baby. If it's XY, it's a baby boy.

German researchers found through research that when the temperature is higher, couples are more likely to have a baby boy, so with global warming, the activity of Y chromosome is more active, and the probability of a baby boy being born is also increased.

2. Sperm quality of future father

With the improvement of living standards, modern people attach great importance to pregnancy preparation. As long as they plan to have children, prospective fathers and expectant mothers will pay great attention to their daily life together, thus improving the quality and activity of Y chromosome, and the probability of Y chromosome combining with chromosomes in eggs is higher.

3. Childbearing age

Every time I go back to my hometown, I feel that many relatives at home have given birth to boys, which is also related to the fact that young people in many small counties get married early, get married early, are in young health and have a greater chance of giving birth to boys. However, in big cities, people generally marry late and have children late. If you get older, the quality of sperm will also be affected, and the chances of giving birth to girls will be higher.

4. Body pH value

Modern people pay more and more attention to the quality of life. As we all know, acidic constitution is easy to get tired and feel tired. Therefore, all kinds of health preservation theories come one after another, and everyone's attention to their own health has also been strengthened. If you want to keep your body in an alkaline environment, you can improve it by adjusting your diet and strengthening physical exercise. Once your body is in an alkaline environment, the chances of having a boy will be greater.

Although the above four reasons are reasonable, they can only be used as influencing factors for the birth of more boys. For every family, it is not the most important to have boys and girls, but the health and safety of the baby are the most important.
