1. Realistic possibility of gender selection by technical means
With the progress of science and technology, people's demand for gender selection is becoming stronger and stronger. At present, some reproductive medicine technologies have been able to select gender through technical means. For example, embryo sex screening and gene screening in IVF technology, sperm screening and embryo sex screening in artificial insemination technology, etc.

In China, some formal reproductive hospitals, such as Peking Union Medical College Hospital and Ruijin Hospital affiliated to Shanghai Jiaotong University School of Medicine, have carried out gender selection services through relevant technical means.
However, there are also some controversies about the choice of gender by technical means. Some people believe that gender selection by technical means breaks the natural law and may lead to social problems of inequality and injustice. However, under certain restrictions, it is still a realistic possibility for technical means to choose gender.
2. Ethical considerations on gender selection of technical means
The choice of gender in technical means involves ethical issues. On the one hand, does the choice of gender involve a violation of human dignity and value? Will it lead to increased gender discrimination? On the other hand, does sex selection violate the natural process of reproduction? These issues need careful consideration and discussion.
In addition, the choice of gender may have a certain impact on the social structure. If the choice of gender becomes a social trend, it may lead to an imbalance in the proportion of men and women, thus posing risks to social stability and population development. Therefore, the choice of gender needs to be limited within a reasonable range to balance the development of science and technology and social stability.
*Later, the choice of gender by technical means also involves the moral choice of families and individuals. Each family should weigh the advantages and disadvantages and decide whether to choose technology to choose gender.
3. Advantages and disadvantages of gender selection by technical means
The advantages and disadvantages of gender selection in technical means need comprehensive consideration. On the one hand, the choice of gender by technical means can realize the family's personal wishes and expectations. For example, some families may want a boy to inherit family blood or a girl to be closer to family members. Technical means can meet their wishes and increase family happiness and life satisfaction.
On the other hand, gender selection by technical means may also lead to some problems. First, gender selection may lead to gender inequality, thus increasing gender discrimination and prejudice. Secondly, the choice of gender may cause imbalance in the proportion of men and women, leading to imbalance in the population structure. Thirdly, the choice of gender by technical means will also increase medical risks and uncertainties, which may lead to some complications at birth.
4. Summary
To sum up, it is a realistic possibility to select gender by technical means, but it needs to be restricted within the scope of ethics and morality. Although the choice of gender by technical means can realize the family's personal expectations and increase the family's happiness, it may also bring some negative effects, such as gender inequality and population structure imbalance. Therefore, the choice of gender in technical means needs careful and careful consideration within a reasonable range.
