Semen Quality and DNA Fragmentation After Limited Testicular Sperm Extraction in Non-Azoospermic Men With ART Failure: A Retrospective Matched Cohort Study.

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
Background and Aims: Testicular sperm extraction (TESE) is sometimes used in non-azoospermic men with persistent infertility, particularly in cases of high sperm DNA fragmentation index (DFI) or repeated intracytoplasmic sperm injection (ICSI) failure. However, the impact of TESE on subsequent semen quality and sperm DNA integrity remains unclear. This study aimed to evaluate the effects of limited TESE on semen parameters and DFI in non-azoospermic men. Methods: In this retrospective matched cohort study, 160 non-azoospermic men with at least three failed ICSI cycles were included between 2021 and 2024. Eighty patients who underwent limited TESE were compared with 80 age- and BMI-matched controls. Semen parameters and DFI were assessed at baseline and after 3-6 months. Data distribution was evaluated using the Shapiro-Wilk test. Continuous variables were reported as mean ± standard deviation or median (interquartile range), as appropriate. Between-group comparisons were performed using independent-samples Results: No significant between-group differences were observed in changes in sperm count (TESE: +8.6 ± 67.3 × 10 Conclusion: Limited TESE does not appear to adversely affect semen parameters or sperm DNA integrity over a short-term follow-up in non-azoospermic men. These findings should be interpreted with caution, and further well-designed prospective studies are required to confirm long-term safety and reproductive outcomes.
