1 · What the graph read from it

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.

2 · The registry

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

Introduction: Sperm immobility is a condition in which sperm are viable but not motile. We reported three patients with sperm immobility, who underwent testicular sperm extraction-intracytoplasmic sperm injection. Case presentation: In case 1, a 32-year-old patient with sperm immobility had previously undergone intracytoplasmic sperm injection with ejaculated sperm; however, pregnancy was unsuccessful. testicular sperm extraction-intracytoplasmic sperm injection was performed at our clinic, and pregnancy was achieved. In case 2, a 23-year-old patient with clinical varicocele whose semen analysis revealed sperm immobility underwent varicocelectomy, without improvement. Using the hypo-osmotic swelling test technique, testicular sperm extraction-intracytoplasmic sperm injection was performed; however, pregnancy was not achieved. In case 3, a 44-year-old patient with sperm immobility underwent testicular sperm extraction, and motile sperm were retrieved. testicular sperm extraction-intracytoplasmic sperm injection using these sperm resulted in pregnancy. Conclusion: Although testicular sperm extraction-intracytoplasmic sperm injection is not considered a solution in patients with sperm immobility, pregnancies were achieved. testicular sperm extraction-intracytoplasmic sperm injection may be successful in some cases in which ejaculated sperm intracytoplasmic sperm injection is unsuitable.
