Intimate Health

Autonomic dysregulation is an underdiagnosed contributor to sexual dysfunction, pelvic pain and incontinence. The autonomic nervous system (ANS) governs erection, ejaculation and bladder function. When it remains in a state of chronic hypervigilance, none of these functions operate optimally.

Non-invasive neuromodulation with NESA XSIGNAL® helps normalize the underlying system that allows your interventions to integrate and sustain their effects.

Abdominopelvic treatments

Autonomic support for overactive bladder, chronic pelvic pain and post-surgical pelvic integration.

Superior hypogastric plexus →
sympathetic-parasympathetic
integration for pelvic organs.

Inferior hypogastric (pelvic) plexus →
autonomic integration for
bladder, uterus/prostate and rectum.

Cavernous nerves (from pelvic plexus)
→ key autonomic input for
erectile tissue and vascular control.

Lumbar sympathetic chain (T11-L2) →
vasomotor-sudomotor
control; involved in stress and pain responses.

Sacral parasympathetic outflow (S2-S4)
+ pelvic splanchnic nerves →
bladder/rectal function and
sexual response.

Pudendal nerve (S2-S4)
+ Alcock's canal
→ key somatic sensory-motor
pathway of the pelvic floor.

Common Indications
Chronic pelvic pain
Functional urinary symptoms (urgency, frequency, pain)
Female sexual dysfunction (pain, lubrication, dyspareunia)
Erectile dysfunction and male sexual function
Postpartum recovery and pelvic floor rehabilitation
Sleep disturbances
Microcirculation and perfusion support
Autonomic dysregulation (sympathetic/parasympathetic imbalance)
  • Support sessions before or after the main intervention to facilitate regulation and improve tolerance
  • Protocol adjustment based on dominant symptoms: pain, sleep, stress, microcirculation
  • Useful during high therapeutic load phases (intensive rehabilitation, return to activity, post-surgical recovery)
  • Monitoring through functional indicators: sleep, fatigue, load tolerance, perceived pain
  • Always within a multimodal and individualized approach

Introducing NESA XSIGNAL®

NESA XSIGNAL® is a non-invasive neuromodulation system that delivers very low-intensity microcurrents through electrodes, with protocols designed to regulate the autonomic nervous system. It is intended to be integrated into clinical practice as part of a multimodal approach.
In Intimate Health, protocols specifically target the autonomic pathways that control sexual function, urinary continence and pelvic inflammation.

The Impact of ANS Regulation in Intimate Health
When specific work on the autonomic nervous system is incorporated, the effect is often systemic: reduced physiological “noise”, more consistent recovery and improved adaptive capacity. In Intimate Health, this may translate into:
Supporting autonomic balance may expand the patient’s adaptive capacity, allowing local interventions such as manual therapy, exercise or procedures to be better tolerated and more consistent over time.

Persistent pain is associated with both autonomic dysregulation and altered central processing. Supporting autonomic regulation may help reduce hypervigilance and complement pain management strategies.

The autonomic nervous system regulates vascular tone and perfusion. Improved regulation may support peripheral comfort, effort tolerance and recovery processes, particularly in patients with coldness, heaviness or reduced perfusion.

Integrating non-invasive neuromodulation as a supportive approach may help address the regulatory component without replacing the primary treatment. The aim is additive: greater stability, improved recovery and better adherence.
