Functional testicular evaluation using PET/CT with 18F-fluorodeoxyglucose.
Article in European journal of nuclear medicine and molecular imaging, 2012. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 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
purposePET/CT using (18)F-FDG is a well-established diagnostic examination in oncology, cardiology and neurology. The clinical significance of nontumoral testicular uptake of FDG is unknown. Functional testicular imaging may have important clinical applications in the diagnosis and prognosis of male infertility. The aim of this study was to determine the andrological value of a FDG PET/CT in analysing testicular function, by correlating the PET/CT data with the sperm parameters.
methodsRetrospective analysis of FDG PET/CT in 20 consecutive cancer patients without testicular pathology in whom two semen samples had been obtained for analysis before any chemotherapy. FDG PET/CT parameters were the mean standardized uptake value (SUVmean), used for measuring the intensity of uptake, and the functional testicular volume (FV). For statistical analysis, a Spearman's rank correlation test and a Mann-Whitney test were used.
resultsOf 20 patients (mean age 22 years), 18 had provided two sperm samples for cryopreservation. Sperm concentration was above 20 × 10(6)/ml in 55% of the patients. The intensity of uptake and the FV were correlated with the total sperm count, the sperm concentration and motility (p < 0.05). The difference in SUVmean between the two testes showed an inverse correlation with sperm concentration (p = 0.036). Normospermic and oligospermic men had significant differences in: (1) mean SUVmean, (2) mean FV, and (3) the difference in intensity of uptake between the testes (p < 0.05).
conclusionThis is the first report on the andrological value of FDG PET/CT in analysing nontumoral testicular function. This pilot study showed a significant correlation between intensity of uptake of FDG and testicular FV with the main sperm parameters. PET/CT with FDG could become a useful new tool in assisted reproductive technologies and other andrological or urological applications.
