Semen retrieval by penile vibratory stimulation in men with spinal cord injury.

Traumatic spinal cord injury resulting from car accidents, falls, violence or sport-related activities is a common occurrence throughout the world. Spinal cord injuries occur most often to young men in their parenting years. Among the medical challenges facing many of these men is the inability to ejaculate via sexual intercourse. To achieve biological fatherhood, their semen may be retrieved by methods of assisted ejaculation. This paper discusses the use of penile vibratory stimulation in men with spinal cord injury, and includes the topics: patient selection and management; proper placement and timing of stimulation; appropriate use of low-amplitude, high-amplitude or dual vibrators; and factors influencing ejaculatory success rate. Also summarized are recent data on semen quality in men with spinal cord injury. When performed properly, penile vibratory stimulation is a safe and easy method of obtaining semen from anejaculatory men with spinal cord injury. Semen quality is better when obtained by penile vibratory stimulation compared with electroejaculation, an alternative method of semen retrieval. For these reasons, and because of the low investment of time and money, it is recommended that penile vibratory stimulation be used as the first line of treatment for anejaculation in men with spinal cord injury.
