Introduction

Low intensity shockwave therapy (LiSWT) has been used to treat sexual dysfunction by inducing genital tissue mechanotransduction. Mechanotransduction is the ability of a cell to actively convert contraction/expansion mechanical stimuli induced by exposure to the shockwave energy into biochemical signals with physiological effects including synthesis of nitic oxide, upregulation of vascular endothelial growth factors, recruitment of endothelial progenitor cells, vasodilation, and expression of tumor necrosis factor alpha mRNA with anti-inflammatory activity. The greater the shockwave energy absorbed in genital tissues, the greater the opportunity for mechanotransduction physiologic effects to occur and improve sexual function. Therefore, effectiveness of LiSWT depends, in part, on applied energy (mJ/mm2) and number of applications (total shocks). In 2019, our sexual medicine clinic began utilizing the SoftWave (Urogold 100™) LiSWT device, FDA cleared for pain amelioration, connective tissue activation, wound healing, and improved blood flow, to treat individuals with vulvas with sexual dysfunction.

Objective

To review the various sexual health concerns in individuals with vulvas effectively treated by LiSWT.

Methods

A chart review was performed of individuals with vulvas with various sexual dysfunctions, including genital pain and genito-pelvic dysesthesia (GPD), who received LiSWT between April 2019 and June 2023. In general, 2400 shocks were applied at energy flux density 0.05-0.08 mJ/mm2, Hz = 3, membrane pressure = 1. The Patient Global Impression of Improvement (PGI-I) was used to assess post-LiSWT outcome; improvement was positive if the post-LiSWT PGI-I ranged from 1-3.

Results

189 women, mean age 32 (range 18–67) years, with sexual dysfunction underwent LiSWT treatments in the 38 months. 18 women with neuroproliferative vestibulodynia (NPV) who underwent vestibulectomy received 3-6 post-operative vestibular LiSWT to reduce post-operative pain and improve wound healing; 83% reported improved PGI-I. 24 patients with hormone-mediated vestibulodynia who elected not to use hormone treatment, underwent vestibular LiSWT; 54% reported improved PGI-I. 25 menopausal patients with persistent symptoms of Genito-Urinary Syndrome of Menopause (GSM) received multiple vestibular LiSWT treatments; 64% improved PGI-I, including reduction of urinary incontinence. 36 women with PGAD/GPD from lumbosacral annular tear-and/or Tarlov cyst-induced sacral radiculopathy who were not candidates for minimally invasive spine surgery or continued to have symptoms after recovering from spine surgery, underwent multiple treatments of lumbosacral spine LiSWT; 58% reported improved PGI-I. 86 patients with neuroproliferative vestibulodynia (NPV) underwent 2-3 pre-operative sessions of vestibular LiSWT immediately prior to complete subepithelial vestibulectomy surgery; they used significantly fewer opioids post-op than those without pre-operative LiSWT based on historical data prior to 2019. All patients received multiple LiSWT sessions to maximize mechanotransduction effects on genital tissues. There were no significant adverse events noted with LiSWT use.

Conclusions

Multiple LiSWT sessions are utilized in individuals with vulvas with sexual dysfunction to maximize mechanotransduction. LiSWT is associated with improved sexual health symptoms ranging from 54% - 75%, not associated with any side effects. More research is needed regarding the role of LiSWT for management of various sexual dysfunctions.
