Trial of Endometrial Scratch Prior to Frozen Embryo Transfer in Patients With Recurrent Implantation Failure
- Conditions
- Recurrent Implantation Failure in Setting of Artifically Prepared Endometrium
- Interventions
- Procedure: endometrial biopsy
- Registration Number
- NCT03157765
- Lead Sponsor
- Brown Fertility
- Brief Summary
Patients with a history of recurrent implantation failure who are planning a frozen embryo transfer (FET) are enrolled into the program. Patients are randomized to an endometrial biopsy prior to starting estrogen to prepare for the transfer of warmed vitrified embryos or to routine care.
- Detailed Description
Patients who failed to achieve a clinical pregnancy after embryo transfer of at least three high quality embryos in at least two IVF or FET cycles and for whom their last failed cycle was a frozen embryo transfer are offered the opportunity to enroll in this study. All patients will follow our routine FET protocol.
On a randomized basis, selected patients will undergo an endometrial biopsy using a Pipelle disposable device in the week prior to starting estrogen to prepare her endometrium.
