“… 15 Similar observations were made in an Asian population by Zamli et al, in which 66.7% and 33.3% of the participants with neurological level above T6 and below T6, respectively, had successful response to PVS. 23 Our study corroborates these observations. All the four participants with higher level of injury (T6-T8) were responders (100%), whereas among the 19 participants with a lower neurological level (T9-T12), only three (18%) were responders.…”

Introduction Infertility in men with spinal cord injury (SCI) occurs due to combination of factors like erectile dysfunction, ejaculatory failure, and semen abnormalities. Penile vibratory stimulation (PVS) is a known method of treatment for anejaculation. Predicting successful outcome of PVS depends on several clinical factors, which assess the intactness of the neural arc pertaining to the spinal ejaculation pattern generator. This study reports the clinical predictors for successful candidacy for a PVS trial in males with SCI. Methods Twenty-three males with SCI, satisfying the inclusion criteria, were recruited in this prospective observational study. Participants underwent two trials of PVS with single high-amplitude vibrator. The clinical predictors recorded were neurological level, superficial abdominal reflex, cremasteric reflex, bulbocavernosus reflex, plantar reflex, ankle jerk, knee jerk, lower abdominal sensation, and hip flexor response. In addition, somatic responses during PVS were recorded and corelated. Participants who had successful ejaculation were “responders” and the others were termed as “nonresponders.” Binary logistic regression analysis of the clinical parameters was done to compare responders against nonresponders. Results Of the twenty-three males (mean age 33.2 ± 6.8 years) with paraplegia, all four persons with neurological level above T9 had successful ejaculation with PVS. Among all the clinical parameters in the study, presence of somatic responses showed statistical significance in predicting successful ejaculation (p-value = 0.02). Conclusion This study reports that in men with SCI, along with the level of injury, somatic responses and other clinical reflexes, should be considered concurrently to predict the outcome of vibrator assisted ejaculation.
