1、 Bioethics
Ethical issues are the core issues facing the three generations of IVF. First of all, ethical issues mainly relate to the way of IVF birth, that is, whether the process of using the third generation IVF technology conforms to ethical and moral standards. The birth of IVF involves the selection and manipulation of embryos, which has aroused the concern of ethical issues. Some ethicists believe that there is a tendency to regard people as tools in the application of this technology, and the treatment of embryos involves ethical issues of life.

Secondly, the genetic transformation involved in the three generation IVF technology has also triggered the discussion of bioethics. Through the third generation IVF technology, some genetic disease genes can be screened out, but there is also the risk of changing the embryonic genes. This change involves the basic life materials of human beings and the core issues of bioethics.
Third, ethical issues also involve the impact of IVF on life. The three generations of IVF babies may face different treatment and expectations from family and society. This difference may have a psychological impact on IVF babies, thus affecting their quality of life and development. Therefore, ethical issues also need to consider the status and treatment of IVF and its family in society.
2、 Family ethical issues
Three generation IVF technology not only involves scientific and medical issues, but also involves family relations and ethical issues. First, in the process of selecting IVF, mother's eggs and father's sperm are often needed, which may have an impact on the relationship between husband and wife. Emotional disputes and family conflicts may intensify, and may bring emotional pressure to both spouses.
Secondly, three generations of IVF babies may bring financial burden to families. IVF technology itself is very expensive, and IVF needs long-term medical care and special environment construction, which requires a lot of money and energy from families. Therefore, family ethical issues mainly involve the economic and psychological pressure of IVF on families.
Third, family ethics also includes the care and education of IVF. IVF babies may need more careful care and cultivation, and families need to invest more time and energy. At the same time, the development of IVF also faces certain potential risks, so families need to have better education and cultivation strategies.
3、 Social ethical issues
The promotion and application of three generations of IVF technology also involves social and ethical issues. First of all, social ethical issues mainly involve fairness and justice. The third generation IVF technology itself is very expensive, which makes only a few wealthy families can bear the costs of this technology. This inequality has caused problems of social justice and distribution fairness.
Secondly, at the social level, the promotion of three generations of IVF technology may lead to the change of the society's concept of fertility. Traditional fertility methods may be gradually replaced by IVF technology, which may have an impact on the traditional family structure and values. Therefore, social ethical issues also involve the impact on fertility concepts and traditional culture.
Third, social and ethical issues also include support and care for IVF and its families. The application of IVF technology needs the support and help of relevant medical institutions and professionals, and the society needs to provide necessary support and care. At the same time, the society also needs to establish corresponding laws and regulations to regulate the application and management of the third-generation IVF technology.
4、 Medical ethics
The application of three generations of IVF technology involves medical ethics issues. First of all, medical ethics mainly involves the professional ethics and responsibilities of medical personnel. In the process of developing IVF technology, doctors need to ensure the safety and legitimacy of the technology in accordance with relevant national laws, regulations and ethical standards, and protect the right to know and privacy of patients.
Secondly, in IVF technology, doctors need to weigh and judge the handling and tampering of embryos. Doctors need to balance interests, risks and ethics to ensure that the application of technology conforms to ethical standards. Medical ethics issues also involve the ethical review of IVF technology research and the protection of test patients.
Third, medical ethics issues also include risk assessment and monitoring of third-generation IVF technology. Doctors need to assess the health risks of patients and monitor the development and health of IVF in a timely manner. Medical ethics issues also involve the evaluation of the safety and effectiveness of IVF technology.
Summary
The ethical problems of three generations of IVF mainly involve bioethics, family ethics, social ethics and medical ethics. These problems involve life, family, society, medical treatment and other aspects, and need to be comprehensively considered and solved. When promoting and applying the third-generation IVF technology, we need to pay attention to these ethical issues to ensure the safety, legitimacy and ethics of the technology, while protecting the rights and interests of patients.
