Abstract
BACKGROUND: To compare in-vitro fertilization and embryo transfer (IVF-ET) pregnancy outcomes following endometrial polypectomy using either a manual mechanical hysteroscopic tissue resection device (mHTR) or traditional mechanical resection with scissors or polyp graspers resection. METHODS: This retrospective study examined 189 infertile patients who had undergone polypectomy prior to IVF-ET at Reproductive and Genetic Hospital of CITIC-XIANGYA. Patients undergoing polypectomy using manual mHTR resection were compared to those having the procedure through traditional mechanical resection. The primary outcome was clinical pregnancy rate (CPR) following the first ET after hysteroscopic polypectomy. Secondary outcomes included miscarriage rates and the optimal time interval from polyp resection to ET. RESULTS: One-hundred eleven (58.7%) patients underwent polypectomy via manual mHTR while 78 (41.3%) patients underwent traditional mechanical resection for polypectomy. Following the first ET, the positive pregnancy rate (80.2% vs. 79.5%; p = 1.000), CPR (70.3% vs. 74.4%; p = 0.652), and MR (11.5% vs. 12.1%; p = 1.000) were similar between those undergoing mHTR and traditional mechanical resection. After stratifying by the number of menstrual cycles from procedure (after next menses; 2 to 3 menstrual cycles; and > 3 menstrual cycles later), there was no differences in CPR when comparing the time from polypectomy and resection type. CONCLUSION: This study suggests no differences in IVF pregnancy outcomes following hysteroscopic polypectomy regardless of surgical type using manual mHTR or traditional mechanical resection and the timing from resection.

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
