The ‘artificial sperm’ were then used to fertilise eggs, leading to the birth of 60 ‘grossly healthy’ baby mice, who went on to have families of their own, the journal Cell reports.
The Kyoto University researchers hope to be able to repeat their success using slivers of skin as starting material, allowing men to father children that are genetically their own.
Josephine Quintavalle, of campaign group Comment on Reproductive Ethics, said the work was ‘total narcissism’ and raised the possibility of ‘male eggs’ from men’s skin and ‘female sperm’ from women’s skin.
She added: ‘Who needs men? Who needs women? All that is required now are artificial wombs and we will have completely rewritten human reproduction.’
科学家近日突破性地培育出“人工精子”,可以使不育男性重获生育能力,帮助数千男性实现“父亲梦”。
在激动人心的实验中,科学家从零开始制造精子,而且首次成功地用这些精子培育出了健康的鼠宝宝。
值得注意的是,这些老鼠宝宝还能自己繁殖后代。这项具有里程碑意义的研究为研发新的治疗不育的药物铺平了道路。每六对夫妇中,就有一对遭遇到令人伤心,但原因不明的不育难题。
但该研究也开启了潘多拉魔盒,带来了伦理困境。这可能使男性在生宝宝的过程中成为“多余的人”,也可能使婴儿完全成为“人造宝宝”。
