Definition of three generations of IVF
The third generation of IVF refers to the embryo transfer between different surrogate mothers by means of assisted reproductive technology (IVF), so as to realize the gene connection of a family. This technology can help couples who are unable to conceive naturally for some reasons or who are not suitable for natural reproduction due to genetic diseases to achieve their reproductive aspirations.

Condition 1: medical conditions
One of the first conditions for three generations of IVF is to have a professional and regular medical institution. At present, many famous hospitals in the world provide third-generation IVF services, such as George Washington University Medical Center in the United States, London HFEA approved hospitals in the United Kingdom, etc. These hospitals usually have high-level medical equipment and qualification certification, which can ensure the safety and success of technology.
At the same time, the couple also need to conduct a detailed physical examination to assess the health of their reproductive system and ensure that there are no genetic diseases or other physical conditions that are not suitable for reproduction. The doctor will check the patient's genetic background, reproductive organ health and other factors to determine whether it is suitable for three generations of IVF.
In addition, the couple also need good psychological guidance to cope with possible stress and emotional fluctuations. Only when medical conditions and psychological conditions are appropriate, three generations of IVF can be carried out.
Condition 2: Economic conditions
The third generation IVF is an expensive medical technology, and the cost usually includes medical examination, drug cost, and the cost in the process of IVF. According to different hospitals and countries, the cost varies greatly, generally ranging from tens of thousands to hundreds of thousands of yuan.
Therefore, both spouses need to have sufficient economic strength to bear these costs. This is also one of the factors to be considered when selecting medical institutions. Some countries and regions provide medical subsidies or subsidies for third-generation IVF babies, which can reduce the economic burden of couples to a certain extent.
Condition 3: Ethical and moral standards
Three generations of IVF babies need to comply with certain ethical standards. This includes respecting patients' autonomy, personal privacy, etc. When conducting technical operations, doctors need to obtain the consent of patients or their legal representatives, and try to ensure the privacy of patients.
In addition, doctors should also follow the principles of honesty, responsibility and fairness to ensure the transparency and traceability of technical operations. A formal medical institution should have an ethics committee to supervise and manage technical operations to ensure that they meet ethical and ethical requirements.
In the three generations of IVF, the couple should also maintain correct ethical concepts, and should not use this technology to conduct gender selection, genetic optimization and other behaviors deviating from ethics.
Condition 4: Requirements of laws and regulations
The third generation of IVF also needs to comply with the corresponding laws and regulations. The laws and regulations of three generations of IVF are different in different countries and regions, and some countries even impose strict restrictions on it.
Therefore, when couples choose to carry out the third generation IVF, they need to understand and comply with the requirements of relevant local laws and regulations. At the same time, medical institutions also need to carry out relevant services within the scope of laws and regulations to ensure the legality and safety of operations.
summary
The third-generation IVF is a technology that requires professional medical institutions, higher economic strength, ethical awareness, and legal and regulatory support. Only when the couple meets the medical conditions, has good economic conditions, and complies with ethical and moral standards, laws and regulations, can the three generations of IVF be carried out smoothly. The emergence of this technology provides a new birth choice for those couples who are unable to bear naturally or have genetic diseases.
