Lateralization of Ovarian Follicles
Bibliographic record
Abstract
BACKGROUND/AIM: To evaluate a possible lateralization of antral follicle count (AFC) based on the finding that endometriosis, if present, is more commonly found in the left hemipelvis. METHODS: We evaluated the records of 6,617 baseline ultrasounds conducted at our Reproductive Center between 2007 and 2011 in a university teaching hospital setting. We included all ultrasounds with an AFC of 1 or greater and excluded those with incomplete documentation or with ovarian cyst, including endometriotic cysts (n = 909). The main outcome measure was the comparison of the number of antral follicles between the right and left ovary. RESULTS: The number of antral follicles in the right ovary (median 18, range 15-22) was significantly higher than in the left ovary (median 16, range 13-20) among women with polycystic ovaries (PCO, AFC ≥24). Similarly, the number of antral follicles in the right ovary (median 8, range 6-10) was significantly higher than in the left ovary (median 7, range 5-9) in women with no PCO but normal ovarian reserve (AFC 10-23). CONCLUSIONS: In women with PCO and non-PCO with normal ovarian reserve, the right ovary contains a higher number of antral follicles than the left ovary.

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.
