Sequelae of IVF
IVF is a kind of assisted reproduction technology, which helps couples who cannot conceive naturally realize their fertility aspirations by combining sperm and eggs in the laboratory and then implanting embryos into the mother's womb. Although IVF technology is very advanced, there are still some potential risks and sequelae.
1. Risk of multiple pregnancy
IVF technology often uses multiple embryos for implantation to improve the success rate. However, simultaneous implantation of multiple embryos can also lead to the risk of multiple pregnancies. Multiple pregnancies can increase maternal and fetal health problems. For example, the risk of premature birth, low birth weight, congenital malformation and growth retardation will increase. In order to reduce the risk of multiple pregnancy, some hospitals have implemented the policy of selective embryo implantation, that is, only one or two embryos are implanted.
In addition, multiple pregnancy will also produce certain pressure and health risks to the mother's body. Pregnant women may have complications such as hypertension, anemia, diabetes and placenta previa during multiple pregnancy. Therefore, for test tube babies, reducing the risk of multiple pregnancy is an important topic.
2. Risk of genetic disease
Through IVF technology, embryos with certain genetic disease risks can be screened to avoid the transmission of these genetic diseases. However, in practice, due to certain errors and risks in the process of embryonic cell sampling and detection, the risk of genetic diseases cannot be completely excluded.
Another possibility is that one of the parents has a potential gene for a genetic disease, but it has not been screened, or it is a new genetic mutation. Therefore, IVF cannot completely guarantee that offspring will not suffer from genetic diseases.
3. Psychological pressure
IVF is often an important hope and expectation for couples, but the whole process is a huge psychological pressure on couples. For couples who cannot conceive naturally, they may have experienced a long period of infertility treatment, and they are under great psychological and physical pressure.
In the IVF cycle, many processes such as egg retrieval and embryo transfer are required. The success of each process and the two-week waiting period will increase the anxiety and psychological burden of couples. Even after successful pregnancy, for women, the whole pregnancy process is also a long and uncertain journey, which may be accompanied by various fears and worries.
4. Social identity
As IVF is an assisted reproductive technology, which is different from natural conception, it may cause some ethical and social identity problems. In some cultural and social environments, IVF may be regarded as an abnormal way of reproduction, and couples may be subject to pressure and discrimination from family, friends and even society.
In addition, the risk of fertility success rate and sequelae brought by IVF will also lead to moral and ethical disputes on the technology. Medical institutions and experts need to balance the factors of bioethics, law and patients' interests to ensure that the application of IVF technology is within the moral and scientific framework.
summary
The development of IVF technology has solved the fertility problem of infertile couples to a large extent, but it is also accompanied by a series of risks and sequelae. Multiple pregnancy risk, genetic disease risk, psychological pressure and social identity problems are important aspects of IVF sequelae. These problems must be taken seriously, and research and management must be strengthened to ensure that risks are reduced as much as possible and better reproductive choices and support are provided for couples.
