Seminal Immature Germ Cells as a Predictor of Microdissection Testicular Sperm Extraction for Development of a Combined Predictive Model.
Article in The world journal of men's health, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeTo investigate the relationship between immature spermatogenic cells (IGC) in semen and sperm retrieval (SR) rate of microdissection testicular sperm extraction (m-TESE) in patients with non-obstructive azoospermia (NOA). MATERIALS AND
methods95 patients with NOA who underwent m-TESE between 2019 and 2024 were included. These patients underwent comprehensive clinical, laboratory, and histopathological evaluations. Multivariable logistic regression analysis was used to explore the association between several variables and m-TESE success rate in patients with NOA, and a predictive model was developed. Model validity and stability were assessed through five-fold cross-validation.
resultsA positive SR was observed in 40.0% of patients undergoing m-TESE. Multivariate logistic regression analysis identified mean testicular volume (TV) (p=0.023, odds ratio [OR]=1.382, 95% confidence interval [CI]=1.046-1.826, area under the ROC curve [AUC]=0.681), IGC in semen (p<0.001, OR=13.757, 95% CI=3.663-51.671, AUC=0.785), and Johnsen score (p=0.005, OR=2.642, 95% CI=1.339-5.213, AUC=0.707) as significant predictors of positive SR, with IGC demonstrating the strongest predictive value. Four predictive models were constructed using the three factors: models A (Mean TV+Johnsen score, AUC=0.726±0.039), B (Mean TV+IGC, AUC=0.859±0.021), C (Johnsen score+IGC, AUC=0.864±0.029), and D (Mean TV, Johnsen score+IGC, AUC=0.874±0.028). Models showed significant improvements in predictive performance. The validity and stability of models B, C, and D containing IGC were better than those of model A without IGC (p<0.05).
conclusionThe presence of IGC in the semen of patients with NOA may serve as a predictive factor for successful SR using m-TESE. Models incorporating IGC significantly enhanced stability and validity, highlighting their potential clinical utility.
