Study design: Retrospective study.
Objectives: Most men with spinal cord injury are anejaculatory. Much has been reported about their semen quality collected by penile vibratory stimulation and electroejaculation (EEJ). What is not well-described is the nature of semen quality in SCI patients who can ejaculate by masturbation. This study was performed to understand the degree to which their semen quality differed from that of anejaculatory SCI patients versus that of healthy non-SCI control subjects.
Setting: University of Miami.
Methods: Retrospective chart review of Male Fertility Research Program participants from 1991 to 2011.
Results: Of 528 SCI subjects, 444 met inclusion criteria of completing an algorithm in which ejaculation occurred by masturbation than the PVS group or EEJ group as the PVS group and control group than the PVS group or EEJ group (41%, P< 0.001).
Conclusion: This is the first report focusing on semen quality obtained by masturbation in men with SCI. Sperm motility was higher in men with SCI who could, versus could not, ejaculate by masturbation. Completeness of injury may contribute to this difference.
