Clinical and research concerns with vibratory stimulation: a review and pilot study of common stimulation devices
The parameters of vibrators used for sexual stimulation in laboratory settings and therapeutic contexts are usually unknown. The unidentified range of vibrator characteristics commonly used for sexual stimulation would help identify
appropriate vibrator for different purposes and clients. Seven vibrators used for sexual stimulation were tested using a piezoelectric accelerometer mounted on their housing to quantify frequency, displacement, and acceleration of each.
Vibratory frequency ranged from 43 to 148 Hz
“Women with spinal cord injuries (SCIs) have predictable alterations in sexual responses. They commonly have a decreased ability to achieve genital sexual arousal. This study determined whether the use of vibratory stimulation would result in increased genital arousal as measured by vaginal pulse amplitude in women with SCIs. Subjects included 46 women with SCIs and 11 nondisabled control subjects. Results revealed vibratory clitoral stimulation resulted in increased vaginal pulse amplitude as compared with manual clitoral stimulation in both SCI and nondisabled subjects; however
We support the right of men with disabilities such as spinal cord injury (SCI) or ejaculatory dysfunction to have children or enjoy a healthy sex life.
Towards that end, we collaborate with leading medical institutions in the research and development of non-invasive products to facilitate ejaculation and the treatment of male infertility, using penile vibratory stimulation – PVS (also designated TMNS – Transcutaneous Mechnical Nerve Stimulation).

The Concept of Penile Vibratory Stimulation (PVS)
While maintaining a healthy sex life is important to many people, the ability to ejaculate is decreased after spinal cord injury. This is the primary cause of infertility in spinal cord injured men. The use of the vibration concept has proven effective in the treatment of infertility. While the technique is often performed initially in a clinical setting, it can also be performed at home – as is being done by more than a thousand men world-wide.
The Medical Explanation
To induce ejaculation by penile vibratory stimulation (PVS) requires an intact ejaculatory reflex arch to provide transmission of afferent stimuli from penis to the sacral, lumbar and lower thoracic segments of the spinal cord, and efferent stimuli from these segments to the ejaculatory organs. The above mentioned spinal cord segments will, even when isolated from the brain, respond to PVS.
