The 33-year-old Wang couple have been married for 3 years and have always wanted a child. Lao Wang worked hard every day. But his wife's stomach has not moved, so anxious that Lao Wang has trouble sleeping day by day, and even the relationship between husband and wife is not as good as before. Lao Wang decided to go to the hospital to check if there was something wrong with him or his wife.
When the test results came out, Lao Wang's wife's physical indicators were normal, and it was found that Lao Wang had long-term alcoholism due to work, resulting in a decline in sperm quality, low vitality, and most of them were malformed, which led to infertility. When Lao Wang heard the news, he burst into tears, and hurriedly asked the doctor what he could do, the Wang family can't die!
The doctor recommends IVF. Lao Wang hesitated with an incredulous expression, and then the doctor took out a few case books in a lost folder and showed them to Lao Wang and his wife.
"You see, this is 33-year-old Mr. Li, but also due to work reasons, sperm survival rate is not high, a year ago the couple came to the hospital for IVF, and now they have given birth to a white fat child.
As soon as Lao Wang heard that it was feasible, he immediately went home and was ready to go to the hospital for a series of treatments. The process went smoothly, and soon after Lao Wang's wife had it. The family is excited to sigh that now with the continuous advancement of scientific level, medical technology is gradually maturing. So that many couples who are infertile also have the opportunity to become parents.
So, what is IVF? Is there a difference between IVF and regular babies in terms of IQ or otherwise?
First, what is IVF, do you understand?
IVF first appeared in the UK in 1978 and did not receive much support due to limited technology at the time. But as the number of people continues to increase, the number of IVF has grown significantly, which precisely reflects the demand for IVF.
According to relevant reports, the number of IVF babies has grown to 1 million between 1978 and 2000. By 2007, the number of IVF babies exceeded 2.5 million. IVF gives couples the opportunity to become fathers and mothers, and a large amount of data proves that IVF has become the main means of curing infertility.
In the mainland, from 1988 to 2004, IVF has reached 100,000. Today, the number exceeds 8 million. From the previous generation to the current four generations of IVF, IVF technology has been continuously improved and updated. So what exactly is a test baby?
Before learning about IVF, most people may think that IVF is a baby that grows in a test tube. In fact, IVF is a popular term, and its professional term is called in vitro fertilization embryo transfer technology.
Specifically, eggs and sperm are retrieved using medical techniques and combined outside the body. After 3-5 days of culture, embryos with good quality, morphological integrity and normal development were preferred. It is then transplanted back into the woman's uterine cavity and the baby is born through delivery.
Today, IVF technology from one generation to the third generation can select excellent cells for transplantation, reducing the probability of babies suffering from genetic abnormalities and other diseases.
However, the process is not so simple, and not all IVF can be successful. Success is conditional, starting with the retrieval of healthy sperm and eggs. Secondly, in terms of selection, if there are weak sperm and less sperm on the male side, it will also reduce the success rate.
In terms of age, the best age is 23-30 years for women and 30-35 years for men. After the optimal childbearing age, function decreases and success rates decrease. For women, a healthy uterus is required, so that the embryo can grow healthily. The normal thickness of the endometrium is about 5-10mm, and too thin and thick endometrium will affect the success rate, and may even cause lesions.
Both physical conditions require that egg cell sperm is indispensable, and if you have the following diseases, you can not do test tubes, such as autosomal dominant inheritance, X-linked recessive genetic diseases, and polygenic genetic diseases. However, two and a half patients with AIDS, syphilis, and hepatitis B can do test tubes. For patients with other diseases who want to do IVF, you need to follow the doctor's advice.
Although the process is difficult, it is worth the hardship for parents to welcome the arrival of their children. So regardless of the outcome during the process, parents need to maintain a good attitude. However, more parents are worried about whether IVF is different from ordinary children?
Second, the difference between IVF and ordinary babies, do you know?
With the continuous upgrading of IVF technology, it is now the fourth generation of IVF. More people will consider whether there is a difference between IVF and ordinary babies, and what is the difference?
In fact, the normal pregnancy process refers to a healthy couple after the husband and wife life, the male will ejaculate sperm, this number can reach hundreds of millions at a time. After passing through the fallopian tubes, sperm find the egg cell and successfully conceive the egg to form a fertilized egg. It is then transferred to the uterus, where it undergoes complex division and differentiation to form small embryos.
In this complex process, it is not necessarily the fastest to run, but it must be healthy and viable sperm to combine with the egg cell. At this time, the uterus has prepared an environment suitable for the growth and development of the embryo. However, this process requires a healthy and normal union of men and women.
As mentioned above, IVF is formed by in vitro fertilization to form embryos into the female uterine cavity. Ordinary babies, that is, normal babies, are fertilized in the body and enter the uterus through the fallopian tubes to grow and develop. This shows that the biggest difference between IVF and ordinary babies is the different fertilization location.
So is there a difference between IVF and ordinary babies when they grow up? Does IVF have an effect on offspring when it grows up?
In fact, in recent decades since the world's first IVF case, in 2004 the news showed that the UK's first IVF baby had grown up and married a bank security guard. And without human intervention, a newborn was successfully born.
In order to confirm this result abroad, researchers have also done a lot of comparative studies. In 2003, the European Union publicly showed that IVF is no different from ordinary babies in terms of physical fitness. U.S. researchers have also made many comparisons with the European Union and come to the same conclusion. The birth of the first test tube baby in the mainland has not been found to be abnormal in all aspects of the baby caused by test tube.
Therefore, a large number of studies have shown that IVF and natural conception, although the two are different in the way of conception, as long as the mother has no abnormal reaction, the quality of sperm and eggs meet certain requirements, and there is no impact on the healthy growth of the embryo. IVF can also form a family and naturally give birth to new life.
Third, is the IQ of IVF lower than that of ordinary babies? Tell you the answer
From the perspective of good fertility, many people will wonder if IVF will have a lower IQ than ordinary babies? So we need to know what are the factors that affect IQ?
IQ, defined from a biological point of view, refers to a baby's ability to perceive the outside world, learn and solve problems, and adapt to new environments. There are many factors that can affect IQ, one is physiological factors, and the other is external factors.
Physiological factors include congenital and acquired formation, including genetic inheritance, self-development and nutritional status. The day after tomorrow includes the factors of pregnant women taking drugs and infections during pregnancy. In terms of innate inheritance, IVF has reduced the low IQ or other problems caused by genes by screening out excellent cells, but has a genetic advantage.
In addition to congenital factors, acquired factors are also important. Nutrition is a vital factor in children's intellectual development. Relevant studies have shown that malnourished children have an average of about 10 points lower intelligence than normal children. The golden period of brain development is mainly the last three months of pregnancy and the six months after birth, so pregnant mothers at this stage need to supplement enough nutrition for fetal development, and the best breastfeeding after the birth of the baby is to enhance the baby's resistance.
In addition, some drugs taken during pregnancy can also affect the intelligence of the fetus. Since many fetal physiology is not yet mature, it can only be absorbed from the mother, which is more likely to cause harm at this time. Drugs like barbiturates and anti-epileptic drugs can cause hydrops in the fetus, which in turn can affect fetal brain health.
Infection during pregnancy is another factor in mental decline in children. Especially in the first trimester, the impact is the greatest, if accidentally infected with cytomegalovirus, toxoplasmosis, etc., it will affect the development of the central nervous system of the fetus, resulting in mental retardation.
External factors such as family and social environment also affect the baby's IQ development to a certain extent. This is because in the process of brain development of infants and young children, the central nervous system development of the brain needs to be constantly stimulated by the environment, such as hearing, touch, vision, etc. can promote the connection between the nerve cells of the brain.
As the first imitation object of the child, the family environment is the first to affect the child's IQ. Parental behavior has a subtle effect on children, and happy families can promote children's intellectual development.
Therefore, whether it is IVF or natural pregnancy, except for the different fertilization location, the two are combined through the parents' germ cells, inherit the genes of the parents and finally give birth, and there is no difference in genetic factors.
In addition to genetic factors, children's intelligence factors are more affected by the above-mentioned acquired factors, so this does not mean that IVF has a lower or higher IQ than ordinary babies.
However, IVF has the option of high-quality and healthy sperm and eggs for transfer and reduces the risk of some diseases when taking sperm and eggs, which is not available in natural pregnancy. So when choosing IVF, what should I pay attention to?
Fourth, what problems do you need to pay attention to when doing IVF?
Moms and dads considering IVF need to pay attention to the following questions:
In the pre-transplant period:
▶ Pay attention to develop good habits and not stay up late. Eat plenty of protein and fresh fruits and vegetables every day. Enhance nutrition, which is beneficial to sperm development in men and egg cells in women.
▶ Folic acid tablets can be taken appropriately to improve the quality of sperm and eggs, and can also prevent the probability of fetal malformations. Follow your doctor's instructions before taking folic acid.
▶ During the period of male pregnancy, try not to smoke and drink alcohol to avoid the decline of sperm quality. You can exercise appropriately to enhance your physique, and after egg retrieval, you can drink diuretic drinks in moderation to prevent ascites and reduce implantation rate.
After transplantation:
▶ The first six hours after the transplant are important, be sure to lie flat. This increases the success rate.
▶Do not bathe for 48 hours.
▶ Supplement more protein, avoid alcohol and tobacco. Eat plenty of vegetables to avoid constipation
▶ After transplantation, pay more attention to rest and do not take heavy objects. Walking slowly and properly is beneficial to restore the body
▶ Get enough sleep and a good state of mind, don't rush and get angry. Medicine has confirmed that bad emotions are not conducive to the growth and development of the fetus.
Epilogue:
In short, IVF is no different from ordinary babies, and there is no difference in IQ, physique, etc. Whether it is IVF or ordinary babies, it is the crystallization of parental love, and the baby born hard through October pregnancy. It is a continuation of family happiness and a gift from God. They should all be treated equally and equally.
Only when doing IVF need to pay attention to improving nutrition and enhancing physical fitness before transplantation. Pay attention to rest and maintain a good attitude after transplantation. To prepare for the arrival of a new life.
