Abstract
AIMS: To establish reference values of semen parameters in a residential, geographic, and age representative sample of healthy Chinese men. METHODS: From a national study of 1,191 healthy Chinese men, semen samples were analyzed from 105 subjects whose wives or partners were pregnant within the 12 months prior to the date when the semen sample was taken. RESULTS: The means, fifth percentiles, and percentages lower than the WHO criteria for semen parameters were, respectively: 75.8 x 10(6)/ml, 17.8 x 10(6)/ml, and 6.7% for sperm concentration; 206.9 x 10(6)/ejection, 26.3 x 10(6)/ejection, and 6.7% for total sperm count; 18.9, 3.0, and 79.1% for rapid progressive motility; 49.1, 25.3, and 52.4% for sperm progressive motility; 73.8, 49.3, and 45.7% for sperm viability, and 49.5, 25.2, and 9.5% for normal morphology. CONCLUSION: The values of semen parameters for Chinese men are lower than the WHO criteria, especially for rapid progressive motility, progressive motility, and sperm viability, and a different standard for Chinese may be needed.

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
