Sex selection: are there technical guarantees for twins of two test tube babies?
With the development of IVF technology, more and more couples choose to achieve their fertility aspirations through IVF. For couples who have had the experience of a single IVF, they may consider alternative options to achieve the goal of family balance. However, it is necessary to elaborate from several aspects whether there is a technical guarantee for the selection of the sex of the twins of the second test tube baby.
1. Technical means and methods
In order to realize the gender selection of the twins of the second test tube baby, it is necessary to first understand the relevant technical means and methods. At present, the most widely used technology is human embryonic germ cell nuclear transfer. This technology can transfer the reproductive nuclei of both parents to the donor oocytes, and then carry out in vitro fertilization and transfer process, finally realizing the selection of embryo sex. In addition, there is also gene screening technology, which can be used to select embryos with sex for transplantation.
However, it should be noted that these technical means and methods are still in the stage of continuous development and improvement. Although some technical support has been provided, not all hospitals and clinics can provide such services. Only some large hospitals with advanced laboratory equipment and professional teams can carry out such operations.
2. Laws and ethics
The restrictions of laws and ethical norms should also be considered before choosing the sex of the second child IVF twins. Different countries and regions have their own restrictions and regulations on sex selective IVF. Some countries and regions prohibit sex selection, which can only be carried out under special circumstances. In other countries and regions, gender selection may be allowed, but it requires strict review and approval.
In addition, ethical norms also have certain restrictions on the selection of sex in vitro babies. This is because gender selection involves moral and social ethical issues. Before deciding on a selective farewell, couples should take full account of family balance and the possible psychological impact on children's future.
3. Risks and side effects
Sex selective IVF twins also have certain risks and side effects. First of all, IVF itself has certain risks, including high abortion rate and premature delivery rate. Secondly, infection and other complications may occur during the transplantation process and related operations. In addition, because sex selection is achieved by screening embryos, it may have a certain impact on embryonic development.
In addition, for women, receiving human embryonic germ cell nuclear transfer technology may increase the risk of endometriosis. In addition, the application of gene screening technology also has certain risks, because it may lead to the transmission of certain genetic diseases and gene mutations.
4. Medical conditions and expenses
Finally, the medical conditions and costs should also be taken into account when selecting the gender of the two IVF twins. Because this technology is not available in all hospitals and clinics, it is necessary to find large hospitals with advanced laboratory equipment and professional teams. At the same time, because a series of complex operations and tests are required, the cost is relatively high.
To sum up, the selection of the sex of two IVF twins needs to take into account the technical means and methods, legal and ethical norms, risks and side effects, as well as medical conditions and costs and other factors. Although there are some technical guarantees, couples should fully understand these factors and have detailed consultation and discussion with doctors before deciding to choose a gender.
