Evidence of a new pattern of ejaculation in men with spinal cord injury: ejaculation dyssynergia and implications for fertility.
Article in Spinal cord, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 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
objectivesTo describe the presence of sperm in the prostatic urethra as a stand-alone ejaculation entity and to assess its characteristics.
methodsThirty-three patients with anejaculation during sexual stimulation were enroled. Penile vibratory stimulations were carried out following bladder catherization and instillation of a pink buffering medium (Ferticult). Two-step catheterisation was then performed: a catheter was inserted through the urethral sphincter into the prostatic urethra to aspirate its content, and then bladder catheterisation was performed to collect the Ferticult. The procedure was repeated in some patients after at least 1 week. The characteristics of the semen collected from each organ were analysed and compared.
resultsA total of 42 trials were obtained from 22 patients. Sperms were found in the prostatic urethra in 21 samples (50%) from 12 patients (11 with spinal cord injury, 1 with diabetes). The colour of all 21 prostatic urethra sperm samples differed from the Ferticult. Sperm motility was greater in 8 samples, sperm count was higher in 10 and pH was different in 10, compared with the bladder samples. The higher overall quality of the sperm allowed cryopreservation in 10 prostatic urethra samples compared with only 5 bladder samples. Four of the five patients who underwent repeated trials had a reproducible pattern of prostatic urethra ejaculation.
conclusionThe presence of sperm in the prostatic urethra most probably results from 'ejaculation dyssynergia', a lack of coordination between bladder neck and external sphincter. Sperm from the prostatic urethra should be systematically sought to improve the outcome of assisted reproduction.
