Abstract

OBJECTIVE
The study was designed to document the effects of regular drainage after penile vibrator stimulation on the quality of semen in spinal cord injured (SCI) men. METHOD: Three tetraplegics and eight paraplegics, aging from 20 to 39 years with neurological levels of C7 to L4 were examined between 1 and 11 years after injury (mean; 4 years 11 months). None had ejaculated after the injury. Eleven responders to penile vibrator stimulation (PVS) were prospectively examined. We used a vibrator (POWER MASSAGER ) with a frequency of 100 Hz and an amplitude of about 2.0 mm. Stimulations were performed mostly 2~3 times per week. Semen quality was characterized by semen analysis every visits. We compared baseline values with the values of post-treatment 1~3 months.
RESULTS
The percentage of motile sperm and the total count of motile sperm per ejaculate were low but increased substantially with treatment.
CONCLUSION
We concluded that repeated ejaculation treatment, for at least 1 month, using the vibrator technique improves semen quality in SCI men who have not ejaculated earlier after injury.
