Cryoneurolysis for Premature Ejaculation

Context and indications

Premature ejaculation affects approximately 20 to 30% of men. It is often related to hypersensitivity of the dorsal penile nerve, causing an excessively rapid ejaculatory reflex.

Cryoneurolysis is offered when standard treatments (behavioral therapy, SSRIs, topical anesthetics) are insufficient or poorly tolerated. This minimally invasive technique modulates penile sensitivity without affecting erection or libido.

Principle

Cryoneurolysis involves applying intense, controlled cold (-40 to -60°C) to the branches of the dorsal penile nerve. The cold temporarily reduces sensory nerve conduction while preserving nerve structure, allowing progressive regeneration over months. The effect is therefore reversible and the procedure repeatable.

Procedure

The intervention is performed on an outpatient basis, under local anesthesia, and takes approximately 30 to 45 minutes:

• Precise localization of the dorsal penile nerve using ultrasound or CT guidance.
• Percutaneous insertion of a thin cryoablation probe (2-3 mm) adjacent to the targeted nerve.
• Application of a freeze-thaw-freeze cycle under real-time monitoring.
• Compressive dressing at the end of the procedure.

Cryoablation is unilateral: only one side of the nerve is treated, which is sufficient to reduce hypersensitivity while preserving normal residual sensation (Prologo et al., JVIR 2013).

Results

In the prospective study by Prologo et al. (Journal of Vascular and Interventional Radiology, 2013) involving 24 patients:

• Technical success: 100%.
• Mean ejaculatory latency time at 6 months: 182.5 seconds (versus less than one minute before treatment).
• 83% of patients reported willingness to undergo the procedure again.
• No procedure-related complications.

Improvement is noticeable from the first week and is maintained for several months to over one year.

Risks

The safety profile is favorable. Possible side effects are minor and transient: local tingling, mild edema, puncture site hematoma. No lasting adverse effects have been reported in published series.

Recovery

Same-day discharge. Sexual rest for 2 to 4 weeks. Follow-up consultation at 4-6 weeks. If the effect gradually diminishes (natural nerve regeneration), the procedure can be repeated.

Practical information

Outpatient procedure under local anesthesia, no hospitalization required. A prior consultation with the interventional radiologist allows assessment of the indication and procedure planning.
