Since the dawn of time, man has needed sex to reproduce. No alternative to be able to create generations and generations. Except thatwith technological and scientific advances, it may be that in the future, we will not need sex to be able to conceive children..
IVF imposes itself in society
In any case, this is the theory of Joyce Harper, a British professor of reproductive science at the University College of London. The scientist based on the fertility problems faced by more and more women and the fact that they spend more time in their careers, which favors the later arrival of children. This last point would also have the consequence the deterioration of the quality of their eggs. Finally, with the progress of In Vitro Fertilization (IVF), the researcher believes that this method would become the most common way to make children. By the end of the century, more than 150 million people will use assisted reproductive technologies.
Questioned by Newsweek, Joyce Harper explains that "the majority of people will not have sex to reproduce". According to her, "women will not even carry more childrenIn addition to IVF, the scientist believes that through genetic analysis, it will be possible for us to identify which embryos may be at risk before they are implanted.
It builds on what is happening now. Today, Sequencing an individual's genome takes only a few hours and costs only around $ 1000. In the near future, the approach could be democratized in order to anticipate cancers, diabetes, allergies or heart disease.
A future potential that raises ethical issues
This way of imagining the conception of children in the future leaves many scientists perplexed. Like always, the ethical question will be at the heart of the debate. As a reminder, last week, a team of Chinese researchers announced that they had modified two binoculars' DNA to immunize them against the AIDS virus. For that, they deleted the CCR5 gene, but the problem is that the deletion of a gene can affect other genes. There is an interaction between all our genes and some researchers think it could change the functioning of other genes, but also the behavior of the cell and the phenotype of the body.
Of course, before this kind of practice is legalized, it will be very clearly think about framing them by being extremely rigorous on the legal and moral framework. But it is clear that In Vitro Fertilization and other genetic manipulations will become more and more common and that sex to conceive children will become more and more rare …
