Abstract

fetched live from OpenAlex

Varying degrees of necrozoospermia are common findings in cases of male sub-fertility; however, it is rare to find persistent and 100 % necrozoospermia. A case of persistent 100 % necrozoospermia is presented in this paper, where aneuploidy analysis was carried out on sperm. No known associations like thyrotoxicosis, genital infection, spinal injury and diabetes were found. Sperm fluorescent in situ hybridization (FISH) was carded out to evaluate sperm aneuploidy for chromosome 1, 9, 12, 13, 16, 18, 21, X and Y and did not show any excess of aneuploidy over controls. To the best of our knowledge, this is the first attempt on meiotic segregation analysis on 100 % necrozoospermic patient. (Asian J Androl 2003 Jun; 5:163-166 )

Not 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.
