PGS是胚胎植入前染色体筛查的缩写，是当今IVF的一大创举 通过检查每一个胚胎，我们可以找到是否这个胚胎是基因上正常的，同时也可以得知胚胎的性别。这对于客人夫妻双方都十分重要。在过去，妊娠成功率远低于现在，其中很大原因在于我们植入的胚胎很大程度上是异常胚胎，但是我们无从得知这个胚胎是正常或者异常的 而现在我们可以知道，这个胚胎是正常的吗？是男胚还是女胚？ 接下来，我们会把每个夫妻的每个胚胎都拍照，而且会把信息共享给他们，客人通常会告诉我们，我想移植四号胚胎，或者五号胚胎也可以。这给准父母提供了极大的选择余地，PGS现在所包含的现实意义远远大于我们当初开始研究使用PGS技术时候所设想的，因此我强烈建议所有客人都要在移植前进行PGS检查，得知结果再做决定。
Do you recommend doing this? Pre-implantation Screening, is one of the most amazing advances in IVF What it lets us do is look at each embryo, and tell if it is normal, and also tell u whether it is male or female embryo. This is very important information for couples In the past pregnancy rates were lower and the reason they were lower is we were putting in embryos that were abnormal We just had no idea they were abnormal Now we know, is the embryo normal? Is it a male? Is it a female? What we do, is we take pictures of each embryo that a couple has and we let them know that information And they tell us, "I want to put in embryo 4, or embryo 5" So it gives intended parents a great deal of choices And I think it is something that is proven be even far more successful than I thought when we first began PGS So whatever you do, I will suggest you do PGs before you decide which embryo you decide for transfe.
