About this study

Official title: Percutaneous Dorsal Penile Nerve Cryoneurolysis as an Adjunct to Combined Pharmacological and Behavioural Therapy for Lifelong Premature Ejaculation: A Single-Centre Randomized Controlled Study

The goal of this clinical trial was to learn whether adding dorsal penile nerve cryoneurolysis to medication and behavioral therapy helps men with lifelong premature ejaculation. Cryoneurolysis is a treatment that uses cold to temporarily reduce nerve signals. The study also looked at the safety of this treatment.

The main questions were:

Read more

Does adding cryoneurolysis make the time from vaginal penetration to ejaculation longer after 3 months? Does adding cryoneurolysis improve premature ejaculation symptoms and satisfaction without worsening erectile function? What side effects occur after cryoneurolysis?

Researchers compared cryoneurolysis plus medication and behavioral therapy with the same medication and behavioral therapy without cryoneurolysis.

Participants:

Took sertraline and tadalafil once daily for 3 months. Received education about behavioral techniques for better ejaculation control. Were randomly assigned either to receive one cryoneurolysis procedure or to receive no cryoneurolysis procedure.

Used a stopwatch to record the time from vaginal penetration to ejaculation and completed questionnaires during follow-up.

Read the detailed description

This prospective, single-centre, parallel-group randomized controlled study was conducted at Biruni University Faculty of Medicine Hospital, Istanbul, Türkiye.

Men with lifelong premature ejaculation were assigned in a 1:1 ratio to one of two treatment groups. Participants in the experimental group received a single session of percutaneous dorsal penile nerve cryoneurolysis in addition to combined pharmacological and behavioural therapy. Participants in the comparator group received the same combined pharmacological and behavioural therapy without cryoneurolysis.

Combined pharmacological treatment consisted of sertraline 50 mg and tadalafil 5 mg orally once daily for 3 months. Both groups also received an individual behavioural education session addressing ejaculatory control and behavioural techniques, including the stop-start technique and, as an alternative, the squeeze technique.

Percutaneous dorsal penile nerve cryoneurolysis was performed under sterile conditions using a CRYO-S® Painless cryoanalgesia system (METRUM CRYOFLEX S.A., Poland) with a 21-G, 0.8-mm cryoprobe. Four dorsal treatment targets were accessed through a single dorsal coronal puncture site. Each target received two 2-minute freezing cycles at approximately -78°C, separated by a 15-second thaw period.

The primary endpoint was the change in stopwatch-measured intravaginal ejaculatory latency time from baseline to 3 months. Secondary and supportive assessments included PEDT, PEP, IIEF-5, patient and partner satisfaction, and adverse events.

A total of 117 participants were randomized. The protocol-evaluable 3-month efficacy population consisted of 107 participants, including 53 in the cryoneurolysis plus combined therapy group and 54 in the combined therapy alone group.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Percutaneous Dorsal Penile Nerve CryoneurolysisProcedure or surgery

    A single percutaneous dorsal penile nerve cryoneurolysis procedure was performed under sterile conditions using a CRYO-S® Painless cryoanalgesia system with a 21-gauge, 0.8-mm cryoprobe. Four dorsal treatment targets were accessed through one dorsal coronal puncture site. Each target received two 2-minute freezing cycles at approximately -78°C, separated by a 15-second thaw period.

  • Sertraline (Oral Antidepressant)Drug

    Sertraline 50 mg was taken orally once daily for 3 months.

  • Tadalafil 5 mgDrug

    Tadalafil 5 mg was taken orally once daily for 3 months.

  • Behavioral Education for Ejaculatory ControlBehavioural

    Participants received one individual educational session addressing premature ejaculation and ejaculatory control. The session included recognition of rising arousal and pre-ejaculatory sensations, the stop-start technique, and the squeeze technique as an alternative. Participants were instructed to practice these strategies at home and during sexual activity.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change in Intravaginal Ejaculatory Latency Time From Baseline to 3 Months

    Intravaginal ejaculatory latency time (IELT) was recorded by participants using a stopwatch and measured from vaginal penetration to intravaginal ejaculation. The primary outcome was the change in IELT from baseline to the 3-month follow-up.

    Measured: Baseline to 3 months

Secondary outcomes (6)
  1. Change in Premature Ejaculation Diagnostic Tool Score From Baseline to 3 Months

    Premature ejaculation symptoms were assessed using the Premature Ejaculation Diagnostic Tool (PEDT). The PEDT consists of 5 items and has a total score ranging from 0 to 20, with higher scores indicating more severe premature ejaculation symptoms. The outcome was the change in PEDT total score from baseline to the 3-month follow-up.

    Measured: Baseline to 3 months

  2. Change in Premature Ejaculation Profile Index From Baseline to 3 Months

    The Premature Ejaculation Profile (PEP) consists of 4 items assessing ejaculatory control, intercourse satisfaction, personal distress, and interpersonal difficulty. Each item was coded from 0 to 4, and the 4 items were averaged to produce a PEP index ranging from 0 to 4. Higher scores indicate a more favorable premature ejaculation-related profile. The outcome was the change in PEP index from baseline to 3 months.

    Measured: Baseline to 3 months

  3. Change in Five-Item International Index of Erectile Function Score From Baseline to 3 Months

    Erectile function was assessed using the five-item International Index of Erectile Function (IIEF-5). The total score ranges from 5 to 25, with higher scores indicating better erectile function. The outcome was the change in IIEF-5 total score from baseline to the 3-month follow-up.

    Measured: Baseline to 3 months

  4. Patient Satisfaction at 3 Months

    Participant satisfaction with treatment was assessed at the 3-month follow-up using a 5-point ordinal scale ranging from 1 to 5, with higher scores indicating greater treatment satisfaction.

    Measured: 3 months

  5. Partner Satisfaction at 3 Months

    Partner satisfaction with treatment was assessed at the 3-month follow-up using a 5-point ordinal scale ranging from 1 to 5, with higher scores indicating greater treatment satisfaction.

    Measured: 3 months

  6. Number of Participants With Procedure-Related Adverse Events

    Procedure-related adverse events were assessed through systematic questioning for numbness or hypoesthesia, paresthesia, dysesthesia, neuropathic or glans pain, hematoma, infection, skin injury, erectile dysfunction, delayed ejaculation, anejaculation, and treatment dissatisfaction.

    Measured: From the cryoneurolysis procedure through 3 months

The record says: finished, as of the sponsor's last update on 16 Oct 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Turkey (Türkiye). Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change in Intravaginal Ejaculatory Latency Time From Baseline to 3 Months (time frame: Baseline to 3 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT07879105, which also lists 8 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 16 Oct 2026.
