Results

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)
