Structural and functional alterations within the testis and epididymis of the Follitropin Receptor Knockout (FORKO) mouse
Bibliographic record
Abstract
Follicle stimulating hormone (FSH) acting on Sertoli cells of the testis plays important roles during reproductive development. FSH-R knockout (FORKO) mice provide a model to examine alterations in testicular and epididymal structure and function in its absence. Examination of the FORKO testis revealed a gross alteration of Sertoli cell structure indicative of a fluid imbalance. Functional parameters, such as ABP secretion were also significantly reduced in FORKO testis. Morphometry revealed quantitative reductions in seminiferous tubule size. The epididymal epithelium, appeared abnormal and morphometry revealed that epididymal tubule size was reduced in the knockout. Computer Assisted Sperm Analysis on sperm from the cauda epididymidis revealed significant alterations in parameters corresponding to sperm motility as well as sperm counts. These data suggest an important role for the FSH receptor on Sertoli cell structure and functions and on epididymal epithelial size and functions in relation to sperm motility.

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.
