了解格鲁吉亚代孕的5天囊胚跟7天囊胚区别

格鲁吉亚代孕,大家一般都会选择第三代试管婴儿。所谓的第三代试管婴儿就是精子和卵子结合成受精卵以后,放在试管中培养5到7天,然后再植入母体。我们把这个培养的过程叫做养囊,把养到5到7天的受精卵叫做囊胚。

在格鲁吉亚,通常会把第三天的鲜胚继续培育到第五天或者第六天,少部分医院会继续培育到第七天。胚胎会生长为有囊胚腔的细胞团,有时分的胚胎养不到囊胚阶段,医生就中止养囊直接冷冻;有的养到第5天或者第6天,剩下的达不到筛查标准的被淘汰掉;有的还会继续养到第7天看看胚胎情况。

就囊胚的培养天数来看5天的最好,6天的次之,7天的再次之。再有就是最好的囊胚评分应该是第5天的囊胚3AA,第6、7天的囊胚4AA,也就说优质囊胚为d5:3AA、3AB、3BA、3BB或是d6:4AA、4AB、4BA、4BB。

格鲁吉亚试管婴儿胚胎在体外发育过程中,有的长得快的,第5天抵达了活检囊胚的规范,胚胎师就会抽取活检并中止养囊,冷冻起来。假定剩下的还有生长的趋向,还有继续发育的可能,那么就会继续培育。假定胚胎师断定剩下的曾经中止发育,无继续培育价值,就会中止养囊。有的胚胎生长比拟迟缓,第5天达不到规范继续培育生长后养到第6或者7天,胚胎师断定合格的话~~这局部胚胎也会被抽取细胞送去中止PGS检查。

当然最终结果还需要听从医生的建议,可能有时候囊胚在5天的时候还没有发育好,医生会建议再观察一天,只要养囊成功后期移植的结果都不会是很差的。
