Now many families want to form the word "good", a man and a woman a baby, this family is very happy, but many people are not what they want, will usher in the second child, the second child, and the first child gender is the same, although some regrets, but also very happy.
But we can also see that the previous generation of parents basically had 6 to 7 children, and the gender of these children is the same, why is this? What factors are involved?
1. Probability
Male sperm also carries the XY chromosome, if it is a sex chromosome Y that binds to the egg, the female will give birth to a male baby after she is pregnant in October, on the contrary, if it is autosomal X that binds to the egg, a baby girl will be born.
In fact, the chance that the fetus will get the constant or sex chromosomes from the father's sperm is equal, so under this principle of equal distribution, there is a certain probability of the formation of the fetal sex!
2. The impact of mental stress on gender
When the mental pressure of the husband and wife is very large, the body is easy to secrete acidic substances, so the probability of having a daughter is a little larger, and sometimes the mental pressure is large, which not only affects the conception, but also has an impact on the sex of the fetus.
Because in a state of stress, the quality of male sperm and the female egg cells, both in quantity and quality, have an impact, especially the viability of sperm, the number, can directly negate whether the conception is successful and the sex of the fetus.
3. It is related to heredity
It is related to heredity, there are boys in the family who inherit genes, and some families are boys for the next generation, so the regeneration of a girl becomes the treasure of the whole family in the palm of the hand.
Some people say that his grandmother's grandmother's grandmother's previous generation, the previous generation will give birth to twin daughters, so the next generation of the family will also have the possibility of giving birth to twin daughters, so it has been a lot to do with the family's genetic genes.
4. Personal physical fitness:
Theoretically, physical fitness is also an important factor affecting the birth of boys and girls, and researchers have found that as people's annual collar increases, the number of sperm in men will gradually weaken, and the quality will gradually decline.
Women, due to the aging effect, the secretion of alkaline substances in the womb is gradually reduced, and the acidic environment will gradually become stronger and stronger, so the probability of older couples having daughters will be higher.
Conclusion: In fact, every little angel is across thousands of mountains and rivers, come to our side, whether male or female is the fate of several lifetimes, whether it is a boy or a girl, is a piece of meat that fell from the mother, can not because of gender on the child has a different view, of course, the baby is still the best fate.
