When it comes to twins, they are all enviable, let alone dragon and phoenix. It is possible to conceive one time and satisfy the experience of having both children, so that the pain of second childbirth can be avoided, but the chance of such a beautiful wish appearing is relatively small.
According to statistics, the probability that the human body will naturally be pregnant with twins is only one in a thousand. With the advancement of society and medicine, this probability has been increased to 3%, let alone the twins. The probability of the appearance of twins is only 25% of twins.
What is a dragon and phoenix?
Dragon and phoenix fetuses refer to twins of different genders, that is, twins with two eggs. Only in this case, can there be dragon and phoenix fetuses. Half of the twins with double eggs may become phoenix and phoenix.
Therefore, the fetus of the dragon and the phoenix may only be a fraternal twin, because two sperms combine with two eggs at the same time to form a fertilized egg, and then develop into twins. They have their own placenta, chorionic membrane and wool membrane, both The blood circulation between them is also not smooth.
Therefore, the sex and blood type of the dragon and phoenix fetuses can be different or the same, and their appearance is the same as that of their siblings.
These three types of women are more likely to have a baby
1. Women with a baby in the family
If in a family There are elders who have given birth to dragon and phoenix fetuses, and their children are very likely to give birth to dragon and phoenix fetuses. This is because the gene has this attribute. Therefore, if one of the spouses carries this gene, it is more likely to have dragon and phoenix fetuses. .
In this regard, scientists have also conducted research and found that if one of the spouses has a history of pregnancy, it will virtually increase the chance of pregnancy, especially for women.
2. Older women who are preparing for pregnancy
According to researchers, the older the woman who is preparing for pregnancy, the greater the chance of getting pregnant. Big.
This is because with age, the endocrine system in a woman's body is likely to be disordered, which leads to an increased possibility of the ovaries expelling two eggs at one time. When these two eggs meet two sperm at the same time When combined into a fertilized egg, twins, or even twins, are formed.
Therefore, when a woman is preparing for pregnancy, if she gets older, she will virtually increase her chances of getting pregnant.
3. Women taking fertility drugs
In daily life, some women will take some fertility aids on the advice of doctors because they are not easy to get pregnant. Drugs, in order to promote the chance of ovulation, will invisibly increase the chance of combining with sperm to form a fertilized egg.
According to data surveys, 25% of women take gonadotropins and other fertility drugs, which increases the chance of getting pregnant with twins or triplets.
So, women who take fertility drugs will have an increased chance of giving birth to fetuses. However, because these drugs contain a large amount of hormones, they can easily cause certain damage to their health, so they must not take them by themselves.
Extended reading: Is the boss born first in the fetus of a dragon and a phoenix?
Because the dragon and phoenix fetuses are formed by two fertilized eggs, there will be a slight difference in the time of implantation. Normally, the implantation time of the boss will be earlier, because this is the reason Can occupy a congenital advantage, occupy a relatively high position in the uterus, in order to benefit oneselfThe growth and development of the body.
But the second child missed the opportunity because of the late implantation time, and could only stay in the lower part of the uterus for development.
Therefore, if the pregnant mother chooses to give birth normally, the second child who is in the lower part of the uterus will be born by the mother first, and the old one who is at the upper end of the uterus will be born later; The incision made by the doctor during the operation is exactly where the second child is located, and the second child will be carried out by the doctor earlier than the boss.
To sum up, among dragon and phoenix fetuses, the second child, not the eldest child, is generally born first.
