Chronic Orchialgia (Investigational Adjunct)
Investigational adjunct for chronic orchialgia (testicular pain) after workup; pharmacotherapy, pelvic-floor physical therapy, and (selectively) microsurgical denervation of the spermatic cord remain evidence-based.
Resumen para el Paciente
- ¿Está esto autorizado por FDA para este uso?
- Not FDA-cleared for chronic orchialgia. FDA cleared medicinal leeches only for venous congestion in microsurgical reconstruction (K040187, 2004). Use here is Tier C investigational.
- ¿Qué evidencia existe?
- Tier C (investigational). No controlled trials exist. Chronic orchialgia is testicular pain persisting at least 3 months and significantly affecting quality of life. Workup must exclude infection, varicocele, hernia, tumor, and referred pain (renal, ureteral, neuropathic). Evidence-based management is multimodal: NSAIDs, tricyclic antidepressants or gabapentinoids for neuropathic features, pelvic-floor physical therapy for myofascial component, and (for selected refractory cases) microsurgical denervation of the spermatic cord with success rates of 70 to 80 percent in published series.
- Riesgos principales
- Bleeding from bite sites for 6 to 24 hours after detachment
- Bruising and tenderness for 5 to 10 days
- Aeromonas infection or local skin infection in a region near the testicle
- Allergic reaction to leech saliva
- Worsening of pain or new neuropathic symptoms if a bite is too close to sensitive structures
- Delay of evidence-based pelvic-floor physical therapy, neuropathic pharmacotherapy, or microsurgical denervation
- If a practitioner inappropriately places a leech on the scrotum, substantial bleeding and infection risk in a uniquely vascular area
- Quién no debería considerar esto
- Anyone where active infection has not yet been treated
- Anyone offered scrotal placement (this is not appropriate)
- Anyone with testicular tumor or inguinal hernia not yet worked up
- Patients with sperm-banking or imminent fertility concerns
- Patients on anticoagulants or with severe anemia
- Patients without prior trials of pelvic-floor PT and neuropathic pharmacotherapy
- Qué preguntar a su clínico
- Has my workup excluded infection, varicocele, hernia, tumor, and referred pain?
- Have I tried at least 12 weeks of pharmacotherapy (NSAIDs, tricyclics, or gabapentinoids)?
- Have I had a course of specialized pelvic-floor physical therapy?
- Has microsurgical denervation of the spermatic cord been considered?
- Where exactly will the leech be placed — confirm it is NOT on the scrotum?
- What is the realistic expected benefit, given there are no controlled trials?
- Cuándo buscar atención urgente
- Sudden severe scrotal pain or swelling (rule out torsion)
- Fever above 38.0 C / 100.4 F or chills
- Visible blood in urine or semen
- Spreading redness, pus, or red streaks around any bite site
- Bleeding from a bite site lasting more than 24 hours
- Hives, throat tightness, or breathing difficulty
Qué NO significa esto
- It does not substitute for urologic workup to exclude tumor, hernia, or referred pain.
- It is not placed directly on the scrotum.
- It does not replace pelvic-floor physical therapy or pharmacotherapy, both of which have evidence support.
- Only anecdotal evidence exists.

Evidence Summary
Chronic orchialgia is testicular pain persisting at least 3 months that significantly affects quality of life. Workup excludes infection, varicocele, hernia, tumor, and referred pain (renal, ureteral, neuropathic). Evidence-based management is multimodal: NSAIDs, tricyclic antidepressants or gabapentinoids for neuropathic features, pelvic-floor physical therapy for myofascial component, and (for selected refractory cases) microsurgical denervation of the spermatic cord with reported success rates of 70 to 80 percent in published series. No published controlled trials of hirudotherapy exist for chronic orchialgia. Scrotal placement is uniquely high-risk for bleeding and infection.
Treatment specifics
How many leeches, where they are placed, how long a session lasts, and whether to repeat are clinical decisions made by a qualified provider under institutional protocol — not something to self-administer. Discuss the specifics with a clinician experienced in medicinal leech therapy. (Clinicians: switch the audience selector in the top bar to “Clinician” to view protocol detail.)
