Will a boy be born earlier than a girl, and will it be a boy or a girl who will be born later

Life is a really amazing thing, and there is a scientific basis for boys to be one to two weeks ahead of their due dates and girls one to two weeks later than their due dates. There are two reasons why boys are born earlier than girls, so let's find out together.

Why are boys prone to early birth?

1. Estrogen and androgen levels have different effects on fetal development.

There is an argument that male and female hormone levels are not the same, so boys and girls develop at different rates in the womb, and boys generally develop faster than girls. For example, the weight of the child at birth.

The same babies are born at term, and the comparison finds that the weight of the male baby will generally be heavier than the female baby; When comparing babies of the same weight, it will be found that the mother's pregnancy time when the male baby is born is shorter than the mother's pregnancy time when the female baby is born.

Moreover, the difference in the level of this hormone does not only act on the fetal period, but also on the height and weight of men and women.

Second, boys love to move and are anxious to come out to see the world.

Doctors also said that there is such a phenomenon, which is related to fetal position activity. Because the general male baby is very active, the more active will naturally come out a few days earlier; And the female treasure is quiet, and she will be born a few days later.

Of course, there are some cases, male treasures don't like to move or female treasures don't like to be quiet, this is normal and can't be generalized. I still hope that the pregnant mother will maintain her mentality, adjust herself, and welcome a smooth delivery is the most important thing!

What should I prepare for an early delivery?

Preparation for childbirth refers to the preparations that need to be made on the eve of childbirth, including the items that need to be prepared, the psychological preparations that need to be made, etc., and the need to make full preparations in three aspects: material, spiritual and physical, so that there will be no mistakes after childbirth, and nothing will be wanted.

Material preparation is the first thing we need to do, the maternity medical certificate (including the pregnant woman's contact card), ** certificate, medical insurance card or publicly-funded medical certificate must be brought, and the delivery bag should also be prepared, including the various items needed by the mother and the newborn baby, the items needed during childbirth, during pregnancy must be prepared one after another, and these things should be summarized together in the 10th month of pregnancy and placed in a place where family members know.

First of all, from a medical and scientific point of view, in fact, boys and girls have already been determined when the fertilized egg is formed, and the length of embryo development will not cause a change in gender, so this has nothing to do with the date of birth, mainly depending on the expectant mother's menstruation, exercise, diet, sitting and resting habits, etc., which will have an impact on the date of birth.

The expected date of delivery is generally calculated from the first day of the last menstrual period, with an average of about 40 weeks. However, for some pregnant women who can't remember the last menstrual period, or who are breastfeeding and have not resumed menstruation, and are pregnant, B-ultrasound examination and other methods are generally used to help calculate the expected date of delivery, so this can only be used as a reference.

Those who are born earlier than the expected date of delivery are not necessarily born prematurely. Many pregnant women and their families think that as long as they give birth earlier than the due date, they will be born prematurely, but this is not the case. Doctors usually refer to premature babies as babies who are 28 weeks old but are born before 37 weeks.

In fact, as long as it is 37 weeks old, it is full-term. All of them are eligible for full-term birth.

There may be a saying among the people that boys are born early and girls are born later, but of course, after our observations, we found that there are many such phenomena. Sometimes when the baby is born late, the mother will have doubts, is the baby born late a girl?

Of course, this can not be generalized, this is also related to fetal position activity, generally speaking, the momentum of the male fetus will be larger, it will come out a few days earlier, and the female fetus is relatively quieter, and the fetal movement is infrequent will stay in the mother's belly for more time. But there are always exceptions, and some boys are not so active, so the due date will be relatively late, so it is not necessarily girls who are born later.

In fact, this is also related to the hormone secretion level of pregnant mothers, the secretion levels of male and female fetal hormones may be different, generally boys will secrete a little more, which makes them develop faster in the mother and fetus than girls, so they will stay in the mother's womb for a shorter time. Of course, this is not entirely true, this is also related to the physique of the pregnant mother, the level of hormone secreted by different physiques is different, and the impact on boys and girls is also different.
