Management of Recurrent Implantation Failure (RIF)

February 9, 2016 updated by: Yasmin Magdi, TopLab Company for ART Laboratories Consultation and Training

The First Study to Compare the Effect of Freeze All Policy Versus Fresh Embryo Transfer After ICSI in Patients With Recurrent Implantation Failure

This is the first study to investigate, whether pregnancy and implantation rates would improve in patients with recurrent implantation failure (RIF), if all embryos were to be frozen and transferred in a consecutive natural cycle.

Intervention / Treatment

Detailed Description

There is growing evidence that elective frozen-thawed embryo transfer in a non-stimulated cycle (freeze-all policy) would eliminate the risk of controlled ovarian stimulation and resulting in better endometrial receptivity and lower uterine contractility as compared with fresh intracytoplasmic sperm injection (ICSI) cycles.

RIF refers to women who fail to achieve a clinical pregnancy, in a minimum of three embryo transfer cycles with at least four good-quality embryos were transferred in a woman < 40 years. It affects approximately 10% of ICSI cases. Many management protocols aimed to enhance ICSI outcome in cases of RIF, however, none of them examined the effect of freeze all policy in this category of patients.

Description

Inclusion Criteria:

  3. all the patients had a history of recurrent implantation failure i.e: failed to achieve a clinical pregnancy after at least three fresh ICSI cycles where at least 8 good embryos were transferred;
  4. their embryos were pushed to Day 5 resulting in blastocysts, and undergo embryo transfer day 5 or vitrification on day 5;
  5. endometrial thickness ≥ 7 mm;
  6. selected embryos for embryo transfer were blastocysts. -

Exclusion Criteria:

Couples with testicular or epididymal sperm were excluded.

Design Details

  • Primary Purpose: Treatment
  • Allocation: Randomized
  • Interventional Model: Parallel Assignment
  • Masking: Double

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
No Intervention: fresh embryo transfer
Patient with RIF underwent ICSI cycle followed by Day 5 fresh embryo transfer.
Experimental: Freeze all
Patient with RIF. All of them underwent ICSI cycle, all their embryos were cryopreserved at Day 5 and transferred in a consecutive natural cycle.
Cryopreservation of human blastocysts for freeze all group has been employed using vitrification. The blastocysts were transferred after thawing in a frozen-thawed cycle.
Other Names:
  • Frozen-thawed embryo transfer

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Clinical pregnancy rate
Time Frame: 4 weeks post embryo transfer
Clinical pregnancy was identified by fetal cardiac activity on ultrasound examination 4 weeks after embryo transfer.
4 weeks post embryo transfer

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Ongoing pregnancy rate
Time Frame: 10 weeks post embryo transfer
Ongoing pregnancy rate was defined as the number of pregnancies with visible fetal heart motion over the number of transferred embryos at 10 weeks' gestation.
10 weeks post embryo transfer
Implantation rate
Time Frame: 6 weeks after embryo transfer
Implantation rate was defined as the number of intrauterine gestational sacs over the total number of embryos transferred.
6 weeks after embryo transfer
