In the past, the dissemination and popularity of medical information was not as good as now, many people did not understand ivory infant technology, and even mistakenly thought that IVF was a baby that grew up from an IVF and did not need to experience a pregnancy in October. Most of this view is due to the lack of clarity on the principles of IVF technology, which can only be understood literally. In fact, IVF technology is only through technical means to help infertile patients transfer embryos to the female uterus to become pregnant, and eventually still have to go through October pregnancy.
Hengjian Overseas pointed out that nowadays, with the progress of medical science and technology, assisted reproductive technology is gradually maturing, and "IVF" has helped many families realize their dreams of parenthood, and has become the best treatment for infertility. However, although more and more people recognize IVF, there are still some people who still have doubts in their hearts, so is it safe to do IVF?
Is IVF technology safe and reliable?
Fertility is based on male sperm and female eggs, with the help of sexual life between husband and wife to complete the "encounter" and "union" between each other, form a fertilized egg, develop into an embryo, settle in the womb, and eventually mature in the wife's body, and then give birth to a baby. However, during the journey of sperm and egg "meeting", sometimes encounter some "bumps", such as female fallopian tube blockage, or narrowing, the man's vas deferens blocked, etc., making it difficult for sperm and eggs to meet. With the development of technology, people will "please" sperm and eggs separately, allowing them to "meet" in test tubes (Petri dishes). Test tubes are glass tubes for chemical tests, but the test tubes used for IVF breeding are much more precise and clean, and most laboratories have now used more sophisticated "Petri dishes" to replace traditional test tubes, but people are still accustomed to calling this technique "IVF technology".
After the woman's eggs are "invited" out, and the man's sperm is "selected for the best job", a certain number of competitive "elite troops" are selected and placed in a test tube with culture solution to combine the eggs with sperm. After the combined fertilized egg culture and development are re-screened, the embryo is transported to the woman's uterus through a special pipeline to settle down and develop into a fetus. Born naturally at the time of gestational term, this kind of child is called "IVF".
IVF technology has been developed for forty years, and IVF technology has developed to the third generation. The first generation of IVF technology is mainly to take sperm and eggs out of vitro, fertilize and then put back into the woman's uterus, that is, the use of IVF instead of the function of the fallopian tube, to solve the female factor caused by infertility.
In order to solve the infertility caused by poor sperm quality in men, a second-generation IVF technology has emerged, in which sperm is injected into the egg in a test tube - intracytoplasmic sperm microinjection technology, which mainly solves the problem that the man suffers from severe oligospermia, weak sperm, malformed spermatozoa, obstructive azoospermia and so on.
The third generation of IVF technology provides couples with genetic diseases with the opportunity to have healthy children, genetic testing before the embryos are transferred into the female uterus, and embryos without pathogenic genes are selected, so as to avoid the birth of genetically diseased children. Take a male patient with hemophilia as an example, in general his son is normal; The probability of daughters being normal or carrying hemophilia genes is 50% (hemophilia gene carriers generally do not develop the disease). In this way, as long as the chromosome examination is determined to be male, it can be guaranteed that it is normal. The eugenic principles of genetic diseases such as thalassemia and color blindness are the same as those of hemophilia.
Genetic diseases that can be diagnosed by third-generation IVF technology can avoid many birth defects and improve eugenics.
Hengjian overseas tips: With the aggravation of environmental pollution in modern society, the increase in people's work pressure and the postponement of the age of marriage and childbearing, infertility is on the rise, and now the number of people doing IVF has only increased, and the IVF technology has been relatively safe and mature after decades of development, which also makes more people feel at ease with this technology.
