AI-Assisted Euploid Embryo Selection for Single-Blastocyst Transfer in Women of Advanced Maternal Age
Effects of Multimodal AI-Assisted Noninvasive Euploid Embryo Selection on Clinical Outcomes After Single-Blastocyst Transfer in Women of Advanced Maternal Age: A Prospective Randomized Controlled Trial
This single-center prospective randomized controlled study will enroll 500 infertile women aged 35 years or older who meet the criteria for fresh day-5 single-blastocyst transfer. Participants will be allocated 1:1 to AI-assisted morphological assessment using EmbryoInsights™ or AI-assisted morphological assessment combined with euploidy prediction using EmbryoInsights™ Plus. The study evaluates whether adding euploidy prediction improves ongoing pregnancy after the first fresh transfer. Secondary outcomes are clinical pregnancy, early miscarriage and live birth. Maternal and infant safety will be monitored.

Gedetailleerde beschrijving
After routine ovarian stimulation, oocyte retrieval and IVF/ICSI, embryos will undergo closed time-lapse culture. Patients will be recruited and provide informed consent on day 3. Eligible patients will be randomized by the random envelope method in a 1:1 ratio on day 5. The control group uses EmbryoInsights™ for morphological assessment. The experimental group uses EmbryoInsights™ Plus to predict euploidy probability and rank morphologically transferable blastocysts, prioritizing those classified as predicted euploid and then using morphology. Senior embryology professionals and study clinicians make the final transfer decision. If AI results are unavailable or the system fails, routine manual assessment is used. An AI result alone does not automatically cancel transfer. The investigational euploidy-prediction model has already been developed. No additional embryo biopsy or biological sampling is required. Follow-up includes hCG at 14 days after transfer, ultrasound at 35 days, assessment at 12 gestational weeks (±7 days), fetal anatomy assessment at 20-24 weeks, delivery, and 42 days postpartum. The primary analysis of ongoing pregnancy will use the intention-to-treat (ITT) population, with all randomized participants analyzed in their originally assigned groups. A per-protocol (PP) analysis will also be performed.

Ongoing pregnancy rate

Ongoing pregnancy is defined as pregnancy reaching 12 weeks of gestation after transfer, with fetal cardiac activity confirmed by ultrasound. The ongoing pregnancy rate is the proportion of transfer cycles in the group that achieve ongoing pregnancy. This outcome is the sole basis for sample size estimation in this study. Assessment: ultrasound at 12 weeks of gestation ±7 days. |
