IVF is not cloning. Its principle is to combine sperm with eggs by external means and then send them back to the mother for culture. The health of IVF is mainly determined by technical conditions, egg health and sperm health.
Technically, first of all, it is necessary to collect and preserve sperm and eggs to ensure that they can be taken out without damage and remain active during fertilization. In the subsequent fertilization process, it is relatively simple, as long as the temperature, humidity and nutrient solution environment meet the survival of germ cells, and the most important thing is to ensure a sterile environment to prevent fertilized eggs from being polluted.
Then there is the process of implantation of fertilized eggs. Under normal circumstances, it is safer to implant directly into the donor's body, and there will be no rejection, which is conducive to the smooth implantation of fertilized eggs. Allogeneic transplantation needs some anti-rejection drugs, which requires a high level of maternal health and requires long-term injection of drugs. This is how many illegal organizations carry out surrogacy business. Surrogates are badly hurt, and there is a great possibility of miscarriage.
The process of taking out and replanting fertilized eggs is harmful to women, and the uterus needs to be broken. Improper operation of this process will lead to the failure of subsequent steps. Both egg retrieval and fertilized egg implantation need to choose a specific time. Before that, fertilized eggs need to be kept outdoors for a period of time, and the length of time will also affect the health of IVF.
After normal implantation, the development process of a fertilized egg is consistent with that of a normal embryo. 10 will come into this world after conception. Under normal circumstances, normally implanted fertilized eggs will not have much problems, and fetal development will not be affected by surgical techniques.
In addition to technology, the main factors affecting the health of IVF are maternal and paternal bodies, and the quality of eggs and sperm determines the health of the fetus. Under normal circumstances, sperm needs fierce competition to get the chance to finally combine with eggs, which can ensure the activity of sperm, but in IVF technology, selection is more important, and we are not sure whether the sperm finally obtained is healthy enough. Moreover, the genetic defects of father and mother themselves cannot be corrected, and many diseases cannot be defective. The same is true for normal babies, and these uncertainties are bound to exist.
IVF technology is a boon for those infertile patients. Now the technology is very mature, which ensures the popularization and application of IVF. You don't need to worry about these aspects. People who accept IVF services must follow the doctor's advice and follow the doctor's guidance. IVF is no different from normal children. I hope you don't have any opinions about them.
