[/]: According to foreign media reports, July 16, published in the journal nature, the United States scientists on human future reproductive technologies and trends predict that within the next 30 years, humans will be able to easily create synthesis, uterus or egg, sperm and fertility by modifying genes "perfect children."
United States scientists forecast include:
1, new baby, or centenarians, alike can have children.
2. Human Infertility will no longer appear. In the lab, anyone can produce sperm or eggs.
3, one can use the pluripotent stem cells derived from the sperm and eggs cells to form a human embryo.
4, the fetus can flow in artificial uterus or placenta float freely. You only need to pass a cord and laboratory of a specific machine.
5, in embryo development stages, can be injected into them, "the box" genes to the prevention and control of certain diseases, such as hereditary Huntington disease, etc. Because the entire process of the embryo growth are in a lab monitor, so it's no mutation can receive timely corrected, even through human intervention methods be improved. Even so, we cannot say that certainly can produce a perfect baby, because people could not through an independent gene can predict it will probably grow up to be a "perfect children."
6, IVF will become more and more expensive, you may only need $ 100; for those in developing countries, poor women, they will have the capacity to pay the costs; in vitro fertilization and for those who are affected by various injuries cannot bear female, IVF will help them to realize the dream of giving birth.
United States Hopkins genetics and reproductive Genetics Centre national policy project director Suzanne-Baru odd, "Although IVF are becoming more common, but people will be crossed the traditional sexual reproductive way instead of the IVF method breed? the problem temporarily unpredictable. Estimated in the next 30 years the human genetic pattern does not change, because human ancient genetic manner without spending money, and you can enjoy the fun of course. ”
Since the late 1980s, scientists began to pay attention to the problem of human fertility. Who in the 25 countries of 33 Research Center organized a standardized diagnostic investigation of infertility, the couple. The results show that developed countries about 5% to 8% of couples affected by infertility, infertility prevalence in some regions is as high as 30%. The world of infertility about 50 million to 80 million. Estimated annual also count about 200 million infertile infertile couples. Experts believe that lead to this result because in the final analysis, people living environment continues to deteriorate. Agricultural fertilizers and herbicides pesticides in toxic substances, decoration material and plastic products contain certain compounds, as well as for animal feed quickly fertility, so that human beings and animals and plants live in soil, water, food and air contamination, thereby directly or indirectly harm the human sperm. In addition, drug addiction, alcoholism, smoking, obesity, social pressure, and so are the male sperm count down.
