A group of British scientists have found a way to turn female bone marrow stem cells into sperm. Professor Karim Nayernia, who leads the team would be ready to start the experiments within the next month, provided, of course, to have the necessary permissions, and is said to be able to produce some of the first female sperm cells within two years. The mature sperm capable of fertilizing the eggs, but will require at least three years of experiments. A sort of "first stage" of sperm cells from bone marrow has already been produced by bombarding the stem cells of the bone marrow of mice with vitamins and other compounds chimici.C 'is just a small detail and should be considered: children born in this way could be exclusively female, why not come into play in the game, the Y chromosome, which is the exclusive property of maschi.In any case it is a hypothesis to side risk of genetic abnormalities . What is more news like a huge open dibbattiti in moral ethics! I do not question the historical event that would mark the emergence of such a discovery, a huge step forward of immense help in the many cases of infertility ... . I will not conceal even a deep sense of pride in belonging to the fairer sex that is more and more as the "most perfect machine of our planet even capable not only to reproduce but to reproduce itself at the very thought ... incredible! really would be all right but what is conveyed behind this discovery? Well frankly I see too many sides negativi.Io personally love the progress of science as well as I am curious to know that there is no limit to human knowledge ... but I am conscious of the fact that there are limits imposed by law and are primary to all others: the nature, which I think is the strongest power in the world and it scares me when you try to challenge it! Conception in terms of the new discovery is equivalent to a conception derived from sexual reproduction between two identical twins for you ... there would be no problem ..?! In my opinion there are some things that are fine as they are and there is a balance in the beauty of this play is not just change it! It is not easy to judge in this regard, this does not want to elaborate, I'll stop here and invite you to write your opinion .......... .
