Timing of Testicular Biopsy in Relation to Oocyte Retrieval and the Outcomes of Intracytoplasmic Sperm Injection.
Article in The Journal of urology, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
purposeWe evaluate microscopic (micro) testicular sperm extraction (TESE) timing relative to oocyte retrieval on intracytoplasmic sperm injection outcome. MATERIALS AND
methodsCouples with nonobstructive azoospermia who underwent intracytoplasmic sperm injection with freshly retrieved spermatozoa were analyzed based on whether micro-TESE was performed at least 1 day prior to oocyte retrieval (TESE-day-before group) or on the day of oocyte retrieval (TESE-day-of group). Embryology and clinical outcomes were compared.
resultsThe percentage of patients who underwent a successful testicular sperm retrieval was significantly lower in the TESE-day-before cohort (62%) than in the TESE-day-of cohort (69%; odds ratio [OR] 1.4, 95% CI [1.1, 1.7],
conclusionsAlthough sperm retrieval and fertilization rates were lower in the TESE-day-before cohort, the 2 cohorts showed comparable embryologic and clinical outcomes. Micro-TESE can be performed before oocyte harvesting to provide physicians ample time to decide between cancelling oocyte retrieval or retrieving oocytes for cryopreservation.
