Abstract
Introduction: The aim of this prospective and randomized study was to evaluate the efficacy of quarterlaser zona thinning assisted hatching (qLZT-AH) in improving the implantation of embryos in patients with previous implantation failure.Material and Methods: A total of 150 patients with a history of previous implantation failure were treated with intracytoplasmic sperm injection, and allocated into two groups: group I, only one previous implantation failure, and group II, repeated implantation failures.The patients in each group were randomized at the time of embryo transfer into a control group (no qLZT-AH) or experimental group where qLZT-AH was performed.For patients with repeated implantation failures, the implantation rate in those who received laser-thinned embryos was significantly higher (p=0.02)than in those whose embryos were not laser-thinned (10.9 and 2.6% respectively).However, this difference was not observed in patients who presented with only one previous implantation failure.The data demonstrate that qLZT-AH is an effective strategy for improving the implantation of embryos in patients with repeated implantation failures.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
