Can test tube babies choose twins?
IVF technology is an important breakthrough in modern reproductive medicine, which provides a reproductive option for couples who cannot conceive naturally. And the twins are the combination of children that many families dream of, so can IVF realize the choice of twins? The following will elaborate on this issue from the perspectives of background introduction, influencing factors, practical experience at home and abroad, and ethics.
Background
IVF refers to the technology that fertilized eggs are cultivated in vitro and transferred to the mother for further development after the embryo has reached a certain stage of development. Dragon and phoenix twins refer to twins of both sexes in a single pregnancy. According to scientific research, the success rate of IVF is related to female age, number of fertilized eggs, fertilization method and other factors. Therefore, in order to realize the selection of dragon and chicken fetus, multiple factors need to be considered.
influence factor
The following main factors need to be taken into consideration in the selection of dragon and chicken foetus:
First, the selection of fertilized eggs. Test tube baby technology can artificially conceive multiple embryos, and then carry out gene testing at an early stage to screen healthy male and female twins for transplantation. This can improve the possibility of realizing the dragon and phoenix foetus.
Secondly, the choice of implantation time. In the process of IVF, the fertilized eggs are generally incubated in petri dishes for 2-6 days, and then the best time is selected to transfer the embryos to the mother. Studies have shown that the timing of embryo transfer into the uterus also has a certain impact on the selection of twins.
Finally, the regulation of breeding environment. The realization of dragon and phoenix fetuses also requires reasonable regulation according to the patient's physique, lifestyle and other factors, so as to improve the survival rate of fertilized eggs and the quality of embryonic development, thus increasing the probability of dragon and phoenix fetuses.
Practical experience at home and abroad
In practice, many hospitals at home and abroad have begun to explore and realize the choice of twins for IVF.
For example, a famous reproductive medicine research center in the United States has tracked more than 500 IVF babies and found that about 30% of IVF babies have finally realized the choice of twins through reasonable embryo screening and implantation timing.
In China, a large general hospital in Beijing has also successfully helped many couples achieve the choice of dragon and phoenix fetuses for test tube babies. Through accurate embryo screening and scientific implantation technology, the hospital has a success rate of about 20%.
Ethics and Conclusion
The selection of twins by IVF also raises some ethical and moral issues. On the one hand, whether the selection of twins by technical means violates the laws of nature has triggered a dispute over life and human dignity. On the other hand, the realization of the choice of twins also reduces the risk of multiple pregnancies to a certain extent, which has a certain protective effect on the health of mothers and infants.
To sum up, in vitro babies can choose twins, but to achieve this goal, multiple factors need to be considered. With the continuous progress of science and technology and the accumulation of experience in medical practice, I believe that more couples can realize their dreams of twins in the future.
