Testing sensation of gently squeezing the testes has diagnostic value in spinal cord injury men.
Article in Spinal cord series and cases, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.

STUDY
designRetrospective cohort study.
objectivesDetermine the diagnostic value of testing the sensation of squeezing the testes.
settingResearch group run by the University of Antwerp.
methodsDuring the clinical examination, it was evaluated if male spinal cord injury (SCI) patients felt gentle squeezing of the testes. The outcome was related to the type of SCI, to the sensations of the light touch of the dermatomes of the perineum, of bladder filling, of overactive detrusor (DOA) contractions during urodynamics, and of electrosensation elicited in different parts of the lower urinary tract. The neurological pathways elicited by these tests were compared.
resultsSeventy-four patients were included, mean age 46 ± 17 years, a number of weeks post SCI 318 ± 586. Sensation in the testes was present in 72.2%. In patients with AIS A, the sensation was found positive in 41%, while all with AIS B-D felt the sensation. Testes sensation was strongly correlated with the sensation of touch of the perineum and with the filling sensation during cystometry, proving a dorsal column pathway. The sensation of DOA contractions and electrosensation in the bladder, bladder neck/proximal, and distal urethra were not significantly related to the outcome of the testicular examination, showing that anterior and lateral spinothalamic pathways were not involved
conclusionsOur data show that sensation from gently squeezing the testes informs about the dorsal column from spinal cord level T10-L2 upwards. The test can help refine the neurologic diagnosis after SCI. We advocate to include this easy-to-do test in the neuro-urologic clinical examination.
