Risks of three generations of IVF
IVF is a kind of baby produced by in vitro fertilization technology, which is widely welcomed by infertile couples. However, three generations of IVF have caused more and more controversy. Although the success rate of this technology continues to improve, there are still some potential risks. This article will discuss the risks of three generations of IVF from different aspects.
1. Risk of IVF process
In vitro fertilization involves multiple steps, including egg sampling, in vitro fertilization and embryo transfer. During egg sampling, women may face some side effects, such as tingling, abdominal discomfort and local infection. In vitro fertilization may lead to the risk of egg or sperm damage. In addition, in the process of embryo transfer, women may be at risk of multiple pregnancies, which may lead to higher health risks for children at birth.
In addition, assisted reproductive technology used in IVF may bring new risks. For example, preimplantation genetic screening can help screen embryos with certain genetic diseases, but it may also lead to problems such as selective parental preference and loss of biodiversity.
2. Risk of genetic factors
The third generation of IVF is carried out by transferring the embryo into the mother's body, which means that the embryo has the mother's DNA. This may lead to genetic related risks, including genetic diseases and gene mutations. For example, some mothers may carry some genetic defects, leading to an increased risk of congenital diseases in newborns. In addition, the mother's lifestyle and environmental factors may also have an impact on the embryo, thereby increasing the risk of birth defects.
In addition, the third generation IVF may also face genetic risks related to germ cell storage. Due to the need to preserve eggs or sperm, these germ cells may be exposed to harmful factors such as radiation and chemicals, thus increasing their risk of disease or mutation.
3. Psychological and social risks
The birth of three generations of test tube babies may have a certain impact on the psychology of family members and children themselves. First, for couples, experiencing multiple unsuccessful IVF processes may lead to depression, anxiety and psychological pressure. Secondly, children may face criticism and discrimination from others when growing up, because they were born in an unnatural way. This may have a negative impact on their psychological and social development, leading to lower self-esteem and social barriers.
4. Legal and ethical risks
Three generations of IVF involve many legal and ethical issues. For example, the selective screening of embryos involves controversial issues such as human genome editing and infant design. In addition, the issue of legitimacy may also cause legal disputes and disputes. Different countries and regions have different legal provisions for third-generation IVF, which may lead to legal uncertainty and conflict.
To sum up, although three generations of IVF have brought hope to many infertile couples, there are still a series of risks. These risks involve the risks of IVF process itself, genetic factors, psychological and social risks, as well as legal and ethical risks. Therefore, before the third generation of IVF, infertile couples should fully understand these risks, and fully discuss and make decisions with doctors.
