Age-Related Changes in Antral Follicle Count among Women with and without Polycystic Ovaries
Bibliographic record
Abstract
BACKGROUND/AIMS: To evaluate follicular phase antral follicle count (AFC) in women of different ages with and without polycystic ovaries (PCO) and to correlate it with early follicular phase serum follicle stimulating hormone (FSH), estradiol, and ovarian volume. METHODS: Retrospective analysis of 1,003 patients' medical records at McGill Reproductive Center. AFC, ovarian volume, serum FSH and estradiol were evaluated and analyzed. RESULTS: The mean numbers of AFC in women without PCO in the age-groups 19-24, 25-29, 30-34, 35-39, 40-44 years were 16, 13, 13, 10, and 6, and in those with MCO 41, 38, 33, 33 and 34 respectively. In women without MCO, AFC was associated with the strongest correlation with age (r: -0.50, p < 0.0001), followed by basal FSH (r: 0.33, p <0.0001). The correlations in women with PCO were less pronounced (AFC, r: -0.24, p < 0.0001; basal FSH, r: 0.17, p < 0.004). CONCLUSIONS: Compared to women without PCO, age-related decreases in AFC and changes in ovarian volume and FSH levels in women with PCO are less pronounced.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
