feasibility analysis
In vitro fertilization and embryo development are completed by means of assisted reproductive technology. Therefore, in theory, sex can be selected. However, at present, most countries and regions have very strict restrictions on gender selection, and only under special circumstances can selection be allowed, such as familial genetic diseases or sex chromosome abnormalities.
Due to social and ethical considerations, there are also disputes about gender selection, and there are some controversial issues, such as: allowing gender selection may lead to gender imbalance; Gender selection may also lead children to become family expectations and pressure sources, which need comprehensive consideration.
Although there are still some limitations and controversies in the technology of gender selection for the eight character test tube baby, under a reasonable moral and legal framework, gender selection for the eight character test tube baby is a feasible technology.
Technical implementation mode
There are two main methods for selecting sex: the first is biological sex identification of embryos. In the early development of the fertilized egg, cells are extracted for genetic analysis, and embryos with normal sex are implanted into the mother; The second is the sperm screening technology, through screening and separating sperm of different genders, the required gender sperm is injected into the mother.
The accuracy of embryo biological sex identification is relatively high, but cell extraction is required at the early stage after in vitro fertilization, which has a certain impact on the development of fertilized eggs. Sperm screening technology has little influence on the fertilized eggs, but the accuracy of sex selection is relatively low.
Different technical implementations correspond to different clinical institutions and hospitals. For example, Reproductive Science Center, a reproductive clinic in California, USA, provides gender selection services, but needs to meet certain medical indications and ethical review.
Ethical and legal considerations
Because gender selection involves many social and ethical issues, many countries and regions have strict restrictions on gender selection. For example, the Measures for the Administration of Human Assisted Reproductive Technology in the mainland of China stipulates that it is not allowed to choose a gender for non genetic and life-threatening sexual diseases, while Taiwan of China allows the selection of gender, but needs to obtain the corresponding permission.
There are also different legislative differences on gender selection internationally. Some countries completely prohibit it, and some allow it when it is medically necessary. For example, the Human Lung Derived Assisted Reproduction Technology and Embryos Act of the United Kingdom stipulates that gender selection can only be used to avoid transmission of genetic diseases or abnormal sex chromosomes.
Under the consideration of ethics and law, the selection of gender requires strict medical and ethical review to ensure that it meets the reasonable purpose and avoid the risk of abuse and decline.
Summary
To sum up, it is feasible in theory to choose the sex of eight character IVF, but in practice it is restricted by national laws and ethics. Sex selection can be attempted through embryo biological sex identification and sperm screening technology. Different countries and regions have different attitudes and regulations on gender selection of test tube babies, which needs to be carried out under a reasonable ethical and legal framework. Sex selection of eight character test tube baby is a field of coexistence of technology and ethics. It needs to balance multiple factors such as social interests, family expectations and individual rights and interests to ensure its development within a reasonable range.
