The live birth rate per egg retrieval following fresh embryo transfer was noted to be higher for TLI cycles (TLI 39.87% vs SC 38.02%, aOR 1.20, 95% CI 1.01 to 1.44). More embryos were available for cryopreservation in the TLI arm (MD 0.08 embryos, 95% CI 0.10 to 0.41). The live birth rate per frozen embryo transfer was not significantly different. The cumulative live birth rate per egg retrieval was significantly higher in the TLI arm (TLI 50.29% vs SC 46.78%, aOR 1.24, 95% CI 1.04 to 1.48)
