胚胎移植后，了解植入率较低是因受精卵不能植入子宫内膜或是植入后妊娠丢失是非常重要的。近来，高敏和特异性放免分析技术能检出植入前胚细胞分泌的小量ｈＣＧ。然而不知道植入前内膜是否能吸收ｈＣＧ。作者对８名生殖腺无功能的患者（年龄范围３３～４６岁），采用激素... After embryo transfer, it is important to understand that the lower implantation rate is due to inability of the fertilized egg to implant into the endometrium or loss of pregnancy after implantation. Recently, high-sensitivity and specific radioimmunoassay techniques have been shown to detect a small amount of hCG secreted by pre-implantation cells. However, it is not known if the intima before transplantation can absorb hCG. The authors of 8 gonadal non-functional patients (age range of 33 to 46 years old), the use of hormones ...
