Sperm Dna Integrity: Correlation With Sperm Plasma Membrane Integrity In Semen Evaluated For Male Infertility
Bibliographic record
Abstract
Previous independent studies have indicated that abnormally low parameters of sperm DNA integrity and sperm membrane integrity correlate to reduced fertility due in part to implantation disorders. The purpose of our study was to evaluate the relationship between sperm plasma membrane functional integrity assessed by the hypo-osmotic swelling test (HOST) and sperm DNA integriy test assesed by DNA fragmentation index (DFI). Semen samples from 102 random patients were evaluated in terms of standard semen parameters and assessed by DFI and HOST. Both tests showed a significant correlation to standard semen parameters (p < .05). In addition, patients with abnormal HOST results had a higher likehood of a subnormal or abnormal DFI result (p < .001). Our results suggest that a common sublethal insult may manifest as abnormalities in both the nucleus and the plasma membrane that act at the implantation and/or subsequent levels of development rather than at the fertilization stage.

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.
