Abstract

fetched live from OpenAlex

We assessed whether estimation of follicular growth, rather than actual measurement of follicular size on the day of hCG trigger, affected pregnancy rates in intrauterine insemination (IUI) cycles. Patient and cycle characteristics were extracted from an existing database. Comparisons were made between the pregnant (defined as a positive beta hCG) and non-pregnant groups for the following variables: patient's age, number of previous IUI cycles, type of ovarian stimulation, endometrial thickness, number of follicles measuring 14 mm and above, pre and post wash sperm parameters, cycle day when IUI was done and number of days between last ultrasound scan and ovulation trigger. A total of 7302 cycles were included in the final analysis. In 4055 cycles (55.5%) the hCG trigger was on the day of the last ultrasound, in 2285 cycles (31.3%) the hCG trigger was 1 day after the last ultrasound, in 850 (11.6%) it was 2 days after the last ultrasound and in 112 (1.5%) it was 3 or more days after the last ultrasound. Sperm parameters, younger maternal age, and the number of follicles above 14 mm were all associated with pregnancy. No association was found between positive pregnancy test rates and the time from last ultrasound to hCG trigger. Planning IUI based on the estimation of follicular growth 1-4 days before trigger, does not affect pregnancy rates.

Full frame distilled prediction

Teacher imitation

Not 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.
