Bladder Neck Obstruction: Experience and Management in a Sperm Bank.
Article in Life (Basel, Switzerland), 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
Primary Bladder Neck Obstruction (PBNO) management provides medical and surgical treatment, such as transurethral incisions that can lead to retrograde ejaculation. The aim of this study was to investigate the maintenance of anterograde ejaculation and semen quality before and after this surgical procedure. A retrospective evaluation was carried out between 2011 and 2020. A total of 73 patients diagnosed with PBNO were recruited. Ejaculatory function, semen quality, and the fertility of recruited subjects were evaluated. Semen parameters-Baseline, 8.2% of patients were oligozoospermic and 12.3% had a semen volume below the WHO 2010 fifth percentile. Post-surgery, 20% of patients were oligozoospermic. We detected a significant decrease in total sperm number, a significant increase in the number of abnormal forms, and a reduction in the leukocyte concentration. Ejaculatory function-A total of 7.7% of patients reported anejaculation after transurethral incision of the bladder neck. Fertility-9.2% of the patients already had children before surgery; 13.8% had naturally conceived children in the years following surgery; 76.9% had no desire for paternity at the time. Our data have important implications for sperm bank management. The alterations in semen parameters and the risk of anejaculation suggest that the use of sperm cryopreservation before surgery for PBNO should be encouraged.
