Brief Summary:
Repeated implantation failure(RIF) is a insurmountable bottleneck in assisted reproductive technology, many studies have considered that the cause of two-thirds of implantation failure is the decreased endometrial receptivity. After exclude some major local immune factors(NK,CD138 cells) and implantation window out of phase, There are still a part of patients infertile .Human chorionic gonadotropin (hCG) is an early pre-implantation signal molecule secreted by the embryo, it can promote endometrial proliferation, increase blood flow and promote embryonic adhesion and inhibit self-regulated apoptosis of trophoblast cells. Previous studies showed that: intrauterine injection of HCG before embryo transfer can improve clinical outcomes in IVF/Intracytoplasmic sperm injection(ICSI). But some studies found that the intrauterine injection of HCG can not significantly improve the success rate of blastocyst transfer, and the reason may be the intrauterine injection of HCG time is too late to significantly increase the implantation rate. Would ahead of intrauterine injection of HCG be more effective? Thus, the patients of repeated implantation frozen embryo cycle according to the random principle accepted two kinds of transplants ways: ①intrauterine injection of HCG before blastocyst transfer; ②blastocyst transfer. Try to understand whether intrauterine injection of HCG can significantly improve the clinical pregnancy rate of blastocyst transfer in repeated implantation failure patients.

Arm Intervention/treatment
Experimental: HCG group
All patients will accept HCG 500IU intrauterine injection 2 days before blastocyte transfer
Drug: HCG
we will use the catheter to pass through the cervix, and after that, the experiment Group will accept 40 μl 500 IU HCG injection into the uterine cavity 2 days before the blastocyst transfer.

Placebo Comparator: control group
All patients will accept same dose of culture medium intrauterine injection 2 days before blastocyte transfer
Other: culture medium
The placebo group will accept 40 μl of culture medium injection into the uterine cavity 2 days before the blastocyst transfer.




Primary Outcome Measures :
  1. clinical pregnancy rate [ Time Frame: 28 days after blastocyst transfer ]

Secondary Outcome Measures :
  1. clinical implantation rate [ Time Frame: 28 days after blastocyst transfer ]
  2. ongoing pregnancy rate [ Time Frame: 70 days after blastocyst transfer ]
  3. ectopic pregnancy rate [ Time Frame: within 3 months after blastocyst transfer ]
  4. abortion rate [ Time Frame: within 28 weeks after blastocyst transfer ]
