The Concentration of Immunoreactive Prostate Specific Antigen is not Decreased in Viscous Semen Samples/Keine Konzentrationsverminderung des immunoreaktiven Prostata-spezifischen Antigens in viskosen Ejakulaten
Bibliographic record
Abstract
Summary: The concentration of immunoreactive prostate specific antigen (PSA) was determined in the seminal plasma of 79 men who were classified into 4 groups according to sperm characteristics: there were 3 groups with low viscosity sperm (normal, large or small volume) and one group with high viscosity and normal volume. PSA concentrations in the group with high viscosity were not significantly different from the group with low viscosity and normal or large volume. PSA was significantly increased only in the “small volume group” (p < 0.01). These results show that absolute amounts of PSA are not decreased in seminal plasma with high viscosity and therefore are not the cause of abnormal liquefaction of the semen in these patients. Zusammenfassung: Bei 79 Männern wurde die Konzentration des immunoreaktiven Prostata-spezifischen Antigens (PSA) im Ejakulat, das nach dem Spermiogramm in 4 Gruppen geteilt wurde, untersucht: Unterschieden werden drei Gruppen mit geringer Viskosität des Ejakulates (bei normalem, großem oder kleinem Ejakulatvolumen) und eine Gruppe mit hoher Viskosität und normalem Ejakulatvolumen. Die PSA-Konzentration in der Gruppe mit hoher Viskosität unterschied sich nicht signifikant von den Gruppen mit geringer Viskosität bei gleichzeitig normalem oder großem Ejakulatvolumen. Lediglich in der Gruppe mit geringem Ejakulatvolumen war PSA signifikant erniedrigt (p < 0,01). Dieses Ergebnis weist daraufhin, daß der absolute Gehalt von PSA im Seminalplasma mit hoher Viskosität nicht vermindert ist und daher für eine abnorme Verflüssigung des Ejakulates bei diesen Patienten nicht verantwortlich ist.

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.
