Report according to British medium, the scientist discovered to hide in "changed sex gene" in the mankind's body recently, this gene could make the mankind keep a sex characteristic, but if it appears an abnormality, the female body then probably grows a male's testicle and beard.There is expert that think, this detection not only breaks with the idea of "sex with living accompany" in the traditional thinking, but also has already finally hoped for change sex surgical operation bring revolution,cheap sunglasses and improve the female and male treatment from the same body infant.The men and women are in general use:All of the distinction between sexes depends it according to report, this research thesis formally and publicly announces on 《cell 》 magazine on the 11th and challenged people the concerning sex simplicity is decided by the idea of X, Y chromosome, because of research middle finger the or so sex develop of the single gene FOXL2 exist the non- sex chromosome that all has at the men and women up.The discovers to also suggest, sex possibility than think in times before of still easily manipulate.The common author of the thesis and Luo Fu Er in medical science institute for research genetics house in England nation?Expect a space to say, the research challenges people to maintain the dogma that the gifted sex sees as the naturally."We always think that our sex with living accompany, male long testicle, female long the ovary is a naturally.But this research suggests, adult's ovary of so can't become testicle, all depend on the gene FOXL2."The animal experiments:Sexual organ occurrence variety the researcher discover, be after the gene that is named FOXL2 in the female rat body be closed, their ovaries start becoming testicle, and start producing the testicle vegetable of healthy male rat.Manage European member living creature of virtuous fortress of German sea of the research laboratory scientist especially the Lai Er say:"We expect that the rat will stop ovulating, however the true state of matter is more shocking."The researcher makes use of the FOXL2 that the genetic engineering technique closed female rat, the ovum in the result ovary all dies, finally will grow up for the filtering of ovum bubble to slowly change into a history to give benefit cell, the history gives benefit cell to make sperm in the testicle.The female rat develops the cell of a manufacturing testicle vegetable from here, the testicle vegetable density heats up at the same time for at first of 100 times.The external appearances, such as size and skin...etc. of the female rat in the experiment and male rat are several to make no difference, and the reproductive organs produce variety, besides which, don't show side effect, test the life span of rat also normal.Applied prospect:Change sex need not do surgical operation researcher and discover that the FOXL2 geneses obviously keep with another the gene SOX9 to reject a relation.When a kind of gene starts, another then automatically close.SOX9 genes usually just in the male activity inside the body, be the male's SOX9 once being opened, the activity of FOXL2 is repressed, and then and life long grind to a stop.This circumstance is exactly the opposite in the female body, the FOXL2 will first be started.The educational circles widespreadly understands a FOXL2 rightness of female maintenanceses daughter the body is as very important as the growth of ovary,mens sunglasses however the scientist doesn't expect that the row ovary cell in the ovary will be absorbed by the SOX9 geneses and then develop a male and grow function.The researcher thinks that the detection leaves a human body application to still need to walk a very long road, however this by all means brings the change of changing sex treatment, even may open non- surgical operation to change sex treatment of first river.By that time, the transexual person will need not to the whole life use a medicine, the gene therapy that need to accept short date went.
