What is the third-generation IVF
The third generation of IVF is also called Preimplantation Genetic Diagnosis, PGD) technology is to screen embryos carrying certain genetic disease genes through assisted reproduction technology and genetic testing, and implant healthy embryos into the mother, so as to have higher accuracy and success rate in screening genetic disease genes, thereby reducing the risk of children's birth.
Conditions for clinical implementation
The implementation of the third generation IVF needs to meet a series of conditions and requirements.
1. Requirements of the Client
The client must be a normal husband and wife relationship that lasts at least two years, and there must be no divorce, separation or other marital disputes. At the same time, both husband and wife must have full capacity for civil conduct, and be over 18 years old and under 45 years old.
2. Requirements for genetic diseases
The third-generation IVF mainly aims at serious genetic diseases, such as blood system diseases, nervous system diseases, musculoskeletal system diseases, rather than curable diseases or disabilities caused by trauma. At the same time, the disease must have a clear diagnostic basis.
3. Embryo acquisition
Embryos can be obtained from embryos after normal fertilization, or from embryos after artificial insemination or in vitro fertilization. The acquisition of embryos must go through legal and compliant procedures to ensure that the source of embryos is legal and compliant.
4. Hospital requirements
The medical institutions for the diagnosis and treatment of third-generation IVF must have certain conditions, such as having relevant technical equipment and professional medical staff team. For example, Peking Union Medical College Hospital is one of the well-known medical institutions in China, which has the qualification and strength to carry out the third-generation IVF technology.
Prospects and challenges of three generations of IVF
The emergence of third-generation IVF technology provides a method for couples carrying genetic disease genes to screen healthier embryos, which is expected to help reduce the spread of genetic diseases. However, the technology also faces some challenges.
First of all, the third-generation IVF technology requires a lot of time and money, which may be difficult for some families with poor economic conditions to afford.
Secondly, although the third-generation IVF technology can exclude embryos carrying genetic disease genes, the current technology is still limited for some complex genetic diseases or polygenic genetic diseases, and cannot fully guarantee the health of embryos.
In addition, the emergence of three generations of IVF technology has also triggered ethical and moral disputes. Some people believe that selecting healthy babies by screening embryos may lead to discrimination and selection of life, and may affect human genetic diversity.
summary
As an assisted reproductive technology, the third-generation IVF has become the choice of some couples carrying genetic disease genes by virtue of its advantage of screening healthy embryos. However, the implementation of the third generation IVF technology needs to meet a series of requirements such as couple relationship, genetic disease diagnosis, embryo source and hospital conditions. Although its prospect is promising, it also faces challenges such as economic burden, technical constraints, ethical disputes and so on. We should explore and apply this technology more carefully to ensure family well-being and social stability.
