In the winter of 1977 the world’s first IVF fertilized egg was successfully laid, bringing hope for life, while early this summer the initial success of artificial sperm research has raised concerns that the existence of men will become redundant. The British reproductive research community must be crowded with scientists who give rise to endless hope and fear. Not to mention that in 2007, British scientists shook the world twice, once in mid-April when Professor Karim Nayenia of the Stem Cell Institute at Newcastle University announced that they had mastered the technology of extracting stem cells from women’s bone marrow and eventually breeding them into sperm; the other time was in early September when the British Artificial Insemination and Embryology Authority announced that British scientists were allowed to create embryos for scientific purposes. human-animal hybrid embryos. The debate about human-animal hybrids is more about whether the lifeforms that are eventually formed are more human or more animal. The panic quickly passed when people finally learned that the so-called human-animal hybrids would not actually produce half-animal humans, that 99% of the genes came from human genetics, and that the scientists promised to end the research within 14 days of embryo formation. The research program ended up dead in the water and was temporarily shelved. Instead, the “artificial sperm” program at the Institute of Stem Cell Research at Newcastle University in the United Kingdom is proceeding in an orderly fashion, and in three to five years, will be put to trial among the 1.5 million infertile couples in the United Kingdom. On July 10 of this year, German scientists Prof. Nayenia published their preliminary research paper in the journal Cytology Development, saying that they had successfully developed sperm by extracting cellular blasts from male rats. The mature sperm was implanted into female rats and seven rats were successfully conceived. Although these rats are short-lived and often sick, scientists at Newcastle University are confident and determined to see the experiment through to the end. According to their expectations, they will soon be able to apply this experiment to humans, and eventually achieve no man’s participation, so that infertile women with their own bone marrow to successfully grow artificial sperm, thus realizing the dream of continuing offspring. Of course, there is no need to panic about this technology. First of all, it is still a mystery whether this technology will eventually reach the general public or not. Moreover, even if it does, it is believed that fertile couples will still choose the natural way to have children. It’s been 30 years since IVF, and I don’t think couples who can have children themselves will care what this technology does for them. Besides, the country must have very strict laws and regulations in place by then, just like the specific implementation details of IVF. As a final step, the final embryo developed from female artificial sperm will be female only because there are no Y cells, which is a disaster for couples who prefer boys. Therefore, such a scientific experiment will eventually affect only a very small percentage of people, and for those who even consider the gender balance of the human race, there is no need to worry about it. I believe that for most couples who want to have children, such scientific findings are of more widespread concern, for example, women who like to eat chocolate are more likely to have girls, while those who like to eat red meat have a greater rate of having boys.
