Microsurgical Onco-Testicular Sperm Extraction in a Patient With Testicular Cancer and Congenital Unilateral Testicular Absence: A Case Report.

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
Introduction: Testicular cancer primarily affects men of reproductive age. Therefore, fertility preservation is important in managing testicular cancer. In patients with a solitary testis, oncological testicular sperm extraction (onco-TESE) is used to retrieve sperm from tumor-bearing testis. Case Presentation: A 39-year-old man with congenital absence of the left testis presented with a 4-month history of progressive right testicular swelling. Laboratory tests showed elevated β-human chorionic gonadotropin and follicle-stimulating hormone concentrations, and ultrasonography showed a heterogeneous hypoechoic mass with microcalcifications. A seminal analysis showed azoospermia with AZFc partial deletion. Following orchiectomy, microsurgical onco-TESE was performed. Motile sperm were successfully retrieved from preserved seminiferous tubules. A pathological examination demonstrated a pure seminoma. In preserved seminiferous tubules, the Johnsen score was 9-10, and partial tubular hyalinization and microcalcifications were observed. Conclusion: Microsurgical onco-TESE is for retrieving sperm in patients with testicular cancer with a solitary testis, even in the presence of impaired spermatogenesis.
