Worldwide, boys and girls grow more than girls

In Britain, the number of children born in every year is more than the girl child. There is no year from the time of Queen Victoria where the girl child is born more. For example, in 2011, girl child was born in Britain, 3,31,35,35. At that time, the child was born 17 thousand more - total 3 lakh 48 thousand 71 people.

According to a World Health Organization report, the natural gender ratio of newly born children is 105 births of children against every 100 girls. This ratio is roughly the same throughout the world. Except for some countries like China or India. Because the child is considered to be more desirable to parents than there.

But just because of the fact that the boy is more likely to grow - it is still unknown to the scientists. So there are more than one theory. The first theory is that growing up as a male is a dangerous matter. The reason being that, in the case of life, the probability of her being killed at a young age is more than that of the daughters. It may be due to accidents, risks, suicides or health problems or for any reason.

Oxford University professor David Steinzelz says that the risk of men being killed more than women in any space and time. So, in the evolutionary terms, the birth of a male child is more than that, in the end, there is a parity in the number of women and men in the age of adulthood.

The child will not be a girl, it is defined as how

The child's sex is determined from the sperm of men - maybe many people know now. If the sperm fertilizing the egg ovary is carried by Y chromosomes, then the child will have a son. And if the sperm is carrying X chromosomes then the child will have a baby.

Now, which will be won in the fertilization competition of billions of sperm, depending on the age of their parents, menstrual cycle, emotional status, food, or even their sexual intercourse.

It is said that Y chromosomal male sperm does not live much longer inside the uterus, but they can run faster. On the other hand, women sperm gets slow but can live longer. One popular theory is that during the period of women's menstrual period, how many couples are getting together and how long they break-depending on whether the child will be a child or a boy.

Sperms that run faster before or after women's ovulation or ovulation, can also be combined with the ovum and the probability of childbirth is increased. On the contrary, the probability of a girl child increases if she breaks for several days after having sexual intercourse several days before ovulation.

But whatever the guardians say, scientists, however, think that there are no particular differences in the results by having sex with these plans. Some studies have shown that if the parents are under stress, then the chances of childbirth increase.

On the other hand, the sons and daughters of the parents living in war or conflict may be more. The question is - if there is no work done in such a planned sex, then what else is happening during pregnancy?

Scientists said some studies have found that early pregnancy is the risk of loss of daughter brow. But some other surveys show that male embryos are risky at the end of the pregnancy and can lead to the birth of a baby.

According to the scientists, it is very difficult to say exactly what happens in the pregnancy and why it happens. On the whole, we see that the boy's fetus reaches more and more and the baby's baby is born.
