Retrospective analysis of personalized embryo transfer timing based on endometrial receptivity testing in patients with implantation failure
ERA-guided pET efficacy study
Personalized embryo transfer timing based on endometrial receptivity analysis mitigates the negative impact of previous failed cycles in repeated implantation failure patients: A single-center retrospective cohort study
ERA-RIF study
| Japan |
Repeated implantation failure (RIF) with no previous pregnancies after two or more embryo transfers
| Obstetrics and Gynecology |
Others
NO
To investigate whether personalized embryo transfer timing based on endometrial receptivity analysis (ERA) could mitigate the negative impact of multiple previous failed cycles in patients with repeated implantation failure.
Efficacy
Pregnancy rate (proportion of cases with blood hCG levels >100 mIU/mL confirmed four weeks after embryo transfer)
Ongoing pregnancy rate (proportion of cases with confirmed gestational sac and fetal heart beats by trans-vaginal ultrasound analysis after nine weeks of gestation)
Observational
| Not applicable |
| Not applicable |
Female
No previous pregnancies
History of two or more failed ART cycles
Azoospermia
Known chromosomal abnormalities
Significant uterine abnormalities (fibroids or adenomyosis >5cm)
Endometrial thickness <7mm on the day of ET
Cases with only cleavage-stage embryos
Cases with PGT-A embryos

ERA testing revealed 49.3% (35/71) receptive and 50.7% (36/71) non-receptive profiles
Overall pregnancy rate after personalized embryo transfer was 35.2% (25/71)
Ongoing pregnancy rate was 25.4% (18/71)
Multivariate analysis showed no significant impact of previous failed cycles on pregnancy rates (adjusted OR = 1.09, 95% CI: 0.89-1.33, p = 0.39)
| 2024 | Year | 12 | Month | 03 | Day |
Median age 37.0 years (IQR: 34.5-40.5), median BMI 20.7 kg/m^2 (IQR: 19.4-22.1), median endometrial thickness 9.7mm (IQR: 8.0-11.0)
Of 99 assessed patients, 28 excluded (6 uterine abnormalities, 6 severe male factor, 15 cleavage-stage/PGT-A embryos, 7 second ERA/no ET), 71 analyzed
None reported
Primary: Pregnancy rate
Secondary: Ongoing pregnancy rate
Yes
