澳大利亚墨尔本Monash大学的一个研究小组正利用DNA指纹图谱和其他分子生物学技术来鉴定在生育过程中产生的有活力的胚胎。当只有一个胚胎被移入到子宫时,方可提高妇女怀孕的机会。目前,美国的许多生育专科医院每次向子宫中植入2个或2个以上在体外受精过程中产生的胚胎。那会导 A team at Monash University in Melbourne, Australia, is using DNA fingerprinting and other molecular biology techniques to identify viable embryos that are born during fertility. When only one embryo is moved into the womb, women’s chances of becoming pregnant can be improved. At present, many gynecological hospitals in the United States are implanted with 2 or more embryos produced during in vitro fertilization each time into the uterus. That guide
