Since ancient times, in terms of having children, everyone has pursued "children and daughters". With the opening of the three-child policy, more and more people have put the plan of having three children on the agenda, and the two children have not been able to put together the word "good". However, mainland law stipulates that doctors are not allowed to disclose the baby's gender before giving birth. Therefore, the most popular topic for pregnant mothers and relatives and friends is to guess whether the baby in the mother-to-be's belly is a boy or a girl. After the implementation of the "comprehensive second child", the experience or folk saying that the boys and girls of the second child already know are even more popular.
After some attempts, whether it was the "Qing Palace Map" or the "Folk Folk Remedies", they did not let the family that sought the dragon and the phoenix get their wish. So what method can make a two-child family know exactly "giving birth to a boy and a girl"? Today, Pregnancy International will introduce you to...
First, let's take a look at the important substances that determine males and females--- chromosomes. Chromosomes are carriers of genetic material genes, the number of normal human chromosomes is 23 pairs, 46, of which 22 pairs are common to both men and women, called autosomes, and the other pair is the deciding other chromosome, called sex chromosomes, male xy, female XX, so the normal male karyotype is 46, XY, female 46, XX.
The third generation of IVF PGS technology, during the fertility process, the embryologist will put the female egg and the male sperm into the same petri dish to fertilize it, and in the next 3-5 days to simulate the uterine environment, by constantly adjusting the proportion of the culture solution, so that the fertilized egg successfully developed into an embryo. According to pregnancy international IVF experts, PGS technology is to extract 1-2 cells of embryos (80-120 cells) before implanting them into the female uterus for sex chromosome screening, detect whether the embryo is xx (girl) or xy (boy), and then implant into the mother's uterus according to gender selection. This technology can 100% solve the needs of boys and girls, and can achieve "children and daughters".
However, in modern society, giving birth to boys and girls is basically the same. The social status of boys and girls is the same as the rights of people, and there is no distinction between who is higher and who is lower. The most important thing is that the baby can be healthy and healthy, and the family is harmonious and happy.
