Glans corona filler: how it works and who it is for

Many men come to my clinic after reading something online, with a clear idea already: «I want the filler». I understand why: it is quick, involves no scalpel and is reversible. But in thirty years of work I have learnt that the right question is not «which treatment?» but «what is the cause?». In this article I try to give you the tools to find your bearings even before booking a consultation.

In a nutshell: how it works

Glans corona filler is an intimate medicine procedure, not a surgical operation. I inject a small amount of hyaluronic acid along the rim of the corona, where the most sensitive nerve endings are concentrated. The gel creates a thin “cushion” that dampens the most intense tactile stimuli during intercourse, without numbing the glans: sensation and pleasure remain.

• Duration: 20–30 minutes, as an outpatient, under local anaesthesia.
• Instrument: I use blunt-tip cannulas, gentler on the tissues than traditional needles.
• Afterwards: you go straight back to your activities; sport after 24 hours; no sexual intercourse for 7–14 days.
• Reversibility: hyaluronic acid is reabsorbed naturally over time and, if needed, can be dissolved with an enzyme, hyaluronidase.

If you want all the details (technique, studies, risks), you will find them in the complete guide to glans corona filler. Here I focus on one thing only: understanding whether it is the right treatment for you.

The real point: where your premature ejaculation comes from

The term “premature ejaculation” covers very different situations. The scientific literature describes four main forms:

To give you a reference: in a large study of almost 500 couples in five countries, the median time between penetration and ejaculation was about 5.4 minutes, with huge differences from one man to another. Time alone is not enough, though: according to the international definition, premature ejaculation is diagnosed only when short latency comes with poor control and personal or relationship distress.

Signs that suggest glans hypersensitivity

None of these on its own is a diagnosis, but together they are useful clues to bring to the consultation:

• the problem has always been there, with different partners and in different situations;
• the reflex is triggered mainly by direct contact with the glans, sometimes within the first seconds of penetration;
• a condom or an anaesthetic spray gives some benefit, a sign that the tactile component matters;
• the erection is good and stable.

When filler is not the right answer

There are situations in which I prefer not to suggest it, or at least not as a first step:

• Erectile difficulties. Some men “speed up” for fear of losing their erection. In this case the erection must be addressed first: the European urology guidelines say so clearly.
• Hormonal or urological causes, such as thyroid disorders or prostatitis: these need to be recognised and treated.
• A mainly psychological or relationship component: performance anxiety, stressful periods, relationship difficulties.
• Subjective form: if your timing is normal, a filler will not change the underlying feeling.
• Active infection or inflammation of the glans or foreskin: this is treated first.
• Short frenulum: sometimes discomfort or tension in the frenulum contributes to the problem, and the solution is a frenuloplasty.

After almost thirty years in practice, saying «this treatment is not for you» is as much part of my job as performing it.

How to prepare for the first consultation

The first consultation lasts 30 to 60 minutes. You can make it much more useful by coming with some information:

1. In the weeks before

   Measure your time

   • Use a stopwatch: start at the beginning of penetration, stop at ejaculation
   • Repeat over at least 3–5 occasions and take the average: that is your baseline IELT

2. Optional

   A short questionnaire

   • There is a validated 5-question questionnaire, the PEDT (Premature Ejaculation Diagnostic Tool), which helps to define the disorder
   • If you like, we can fill it in together during the consultation

3. What to bring

   Your history

   • The medicines you take and the treatments you have already tried (sprays, creams, drugs, exercises)
   • Any recent tests, for example thyroid or urine tests
   • If your partner wants to come, she is welcome: it is not compulsory

4. At the consultation

   Conversation, examination and sensitivity test

   • We go through the history of the problem together
   • I examine the glans corona and carry out a sensitivity test
   • If filler is indicated, we discuss quantity, timing, risks and realistic expectations

Consultations take place in Turin, Asti and Alessandria; the treatment is performed in Turin, at Aesthetic Clinic.

What to expect, honestly

I always tell my patients: in medicine 1+1 does not always make 2. My aim is not to persuade you to have a treatment, but to help you understand whether it makes sense for you, with all the information in hand.
