Subversion of human history's reproductive technology, skin creation or achieved within 20 years

Sexual activities play a key role in the evolution of life on Earth. The reproductive reproduction of almost all animals and plants on the planet is inseparable from sexual activities. Sexual activities can pass on genetic material from generation to generation. However, geneticists at Stanford University in the United States believe that human reproduction may no longer require sexual activity in the future. Geneticists claim that humans using skin samples to perform laboratory man-made can be achieved within 20 years.

Professor Hank-Geli, a genetic ethics expert at Stanford University in the United States, believes that human reproduction will be subject to historic changes, and that human activities may require only laboratories, not necessarily bedrooms. Gree explained that it is only necessary to collect a little skin cells from the mother, extract genetic material from them to produce eggs, and collect sperm samples from the father; the two combine to form a fertilized egg.

Through this process of creation, parents can effectively “design” their future children, who can choose the most desirable one of the approximately 100 embryos formed. This sounds a bit like the plot in the American sci-fi movie "Millennium", which gives children an idealized appearance through genetic selection. Greeley said, "In 20 to 40 years, when a couple wants a child, the father only needs to provide sperm, and the mother only needs to provide some skin cells. Parents get a variety of embryos, one of which may be very serious. Incurable diseases that can affect 1% to 2% of embryos."

In "The End of Sex and the Future of Human Reproduction," Professor Graley details his views on the future reproductive patterns of mankind. Greeley claims that stem cell technology has made his vision a reality. Humans have learned to use genetic techniques to accurately examine the specific state of an embryo during in vitro fertilization. Scientists have also been able to use stem cells to generate germ cells such as eggs and sperm in the laboratory.

According to Greeley, the combined use of cloning and stem cell technology allows women to be protected from invasive procedures during in vitro fertilization. He only needs to extract genetic material from the skin cells, which are then used to generate stem cells, which are then used to generate eggs, which are then used to form fertilized eggs using traditional in vitro fertilization techniques.

Preimplantation embryo genetics diagnostic techniques can help parents choose their best embryos without disease. The pre-implantation embryo genetics diagnostic technique was first applied 25 years ago, and this technique can be used to find many problems, and it is now more widely used.

According to Greeley, this technology will make asexual reproduction more and more economical and easier than traditional reproductive methods. Although this method may be expensive, it can effectively eliminate many serious genetic diseases and save potential huge medical expenses in the future.

However, this technology can also cause many serious ethical issues. Many people oppose the use of genetic technology to select "designing babies."
