Abstract
Introduction: The efferent ductules that arise from rete testis convey spermatozoa from the testis to the epididymis. Seasonal studies on morphological and immunohistochemical characteristics of camel reproductive organs are rare. This study aimed to elucidate the morphometric changes and immunoreactivities of S-100 and alpha smooth muscle actin (α-SMA) in dromedary camel efferent ductules during rutting (reproductive) and non-rutting (non-reproductive) seasons. Methods: Simple (proximal part) and pseudo-stratified (distal part) columnar epithelium lined the efferent ductules, which contained ciliated and non-ciliated cells that gave the epithelial lining its wavy shape. Results: The epithelium was significantly higher and stereocilia were insignificantly longer during non-breeding season as compared to breeding season. There was a significant increase in luminal diameter and muscular coat thickness during breeding season. The epithelium of proximal and distal segments as well as smooth muscles and surrounding connective tissue exhibited positive S-100 reactions during breeding and non-breeding seasons; this reaction was stronger in breeding season than non-breeding season. The epithelial cell reaction was negative or very weak to α-SMA during breeding and non-breeding seasons, whereas smooth muscle and surrounding connective tissue showed positive reaction which was stronger in breeding season. Conclusion: In conclusion, S-100 and α-SMA show seasonal morphometric and immunoreactivities variations in camel efferent ductules; these variations could be associated with the physiological condition during breeding and non-breeding seasons.

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
