What Is Erectile Dysfunction?
Erectile dysfunction is defined as the persistent inability to achieve or maintain an erection sufficient for satisfactory sexual intercourse. It is not simply an occasional difficulty — which is entirely normal — but a recurring pattern that affects quality of life and, often, emotional wellbeing.
ED is far more common than many men realise. The Massachusetts Male Aging Study, one of the most widely cited epidemiological reports in men’s health, found that approximately 52% of men between the ages of 40 and 70 experience some degree of erectile dysfunction, ranging from minimal to complete. Studies suggest that prevalence increases with age, but ED can and does affect men in their 20s and 30s as well.
Causes are typically classified as physical (vascular disease, diabetes, hormonal imbalance, neurological conditions, medication side effects), psychological (stress, anxiety, depression, relationship issues), or — most commonly — a combination of both.
Treatment Options for ED: How They Work
Modern ED treatment is highly effective for the majority of patients. The appropriate option depends on the underlying cause, overall health, medication tolerance, and personal preference. A thorough consultation with a physician is essential before starting any treatment.
Oral PDE5 Inhibitors (Sildenafil / Tadalafil)
PDE5 inhibitors — the drug class that includes sildenafil (the active ingredient in Viagra) and tadalafil (the active ingredient in Cialis) — are the recognised first-line treatment for ED in most international clinical guidelines. They work by relaxing smooth muscle tissue in the penis, increasing blood flow in response to sexual stimulation.
Sildenafil is typically taken 30–60 minutes before sexual activity and is effective for approximately 4–6 hours. Tadalafil has a longer duration of action (up to 36 hours) and is also available in a low daily-dose formulation for men who prefer not to plan around a pill. Clinical evidence consistently reports response rates of 70–85% in men with mild to moderate ED, though outcomes vary based on the underlying cause.
Common side effects include mild headache, facial flushing, and nasal congestion. PDE5 inhibitors are contraindicated in patients taking nitrate medications (commonly used for angina/chest pain), and a medical history review is mandatory before prescribing.
Intracavernosal Injection (ICI) Therapy — Trimix / Bimix
For patients who do not respond adequately to oral medication — including those with more severe vascular ED, post-prostatectomy ED, or certain neurological conditions — intracavernosal injection (ICI) therapy is a well-established second-line option. This involves injecting a small amount of vasoactive medication directly into the erectile tissue of the penis (the corpus cavernosum), producing an erection typically within 5–15 minutes.
The most commonly used formulation is Trimix, a combination of three agents: alprostadil, papaverine, and phentolamine. Bimix (alprostadil and papaverine, without phentolamine) is a common alternative. Studies indicate that ICI therapy achieves satisfactory erections in 80–90% of patients who have not responded to oral PDE5 inhibitors.
Under physician guidance, patients are trained to self-administer the injection at home. The needles used are very fine (similar to insulin needles), and most patients report only minimal discomfort after the initial training sessions. ICI therapy requires careful dose calibration and ongoing medical supervision.
Dr. Karibe’s Note
Many of our international patients are surprised to find that ED can be discussed openly and addressed practically in a Japanese clinic setting.
A common question I receive is whether Japanese doctors will prescribe sildenafil or tadalafil to foreign nationals — the answer is yes, provided a standard medical evaluation confirms it is safe to do so.
For patients who have already tried oral medication elsewhere without satisfactory results, ICI therapy with Trimix or Bimix is an option we can discuss in detail during a consultation at BIOTOPE CLINIC.
Comparing ED Treatment Options
| Treatment | How It Is Taken | Onset | Duration | Typical Candidate | Key Considerations |
|---|---|---|---|---|---|
| Sildenafil (PDE5 inhibitor) | Oral tablet | 30–60 min | 4–6 hours | Mild–moderate ED; first-line treatment | Contraindicated with nitrates; requires sexual stimulation |
| Tadalafil (PDE5 inhibitor) | Oral tablet (on-demand or daily) | 30–60 min | Up to 36 hours | Mild–moderate ED; men preferring flexibility | Daily dose option available; same nitrate contraindication |
| ICI Therapy (Trimix / Bimix) | Self-injection into penile tissue | 5–15 min | 30–60 min (dose-dependent) | Moderate–severe ED; non-responders to oral therapy | Requires physician training; risk of priapism if overdosed |
Cost of ED Treatment in Tokyo
At BIOTOPE CLINIC in Shirokanedai, the initial consultation fee is ¥3,300. A consultation with Dr. Karibe specifically is ¥2,200. These fees are separate from medication costs.
Oral ED medications (sildenafil and tadalafil) prescribed at cosmetic/private clinics in Japan are not covered by national health insurance and are priced per tablet. Costs at private clinics in Tokyo typically range from approximately ¥500–¥2,500 per tablet depending on dosage and formulation, though pricing varies between institutions and should be confirmed at the time of consultation.
ICI therapy involves both the cost of the medication itself (compounded Trimix or Bimix preparations) and an initial training session with the physician to ensure safe self-administration technique. Patients should budget for follow-up consultations to adjust dosing. The total cost of starting ICI therapy — including the consultation, initial medication supply, and training — typically falls in the range of ¥15,000–¥40,000 for the first visit cycle, with ongoing costs for medication refills thereafter. These figures are indicative; exact pricing depends on dosage requirements and consultation frequency.

What to Expect: Before, During, and After a Consultation
Before Your Appointment
Patients are asked to complete a medical history form prior to or at the time of their consultation. It is helpful to note the duration and pattern of ED symptoms, any relevant existing conditions (cardiovascular disease, diabetes, hypertension), and a current medication list — particularly if taking nitrates, alpha-blockers, or antihypertensives, as these interact with ED medications.
During the Consultation
The consultation at BIOTOPE CLINIC is conducted in English with Dr. Karibe. The discussion covers symptom history, medical background, lifestyle factors, and treatment goals. A brief physical assessment may be recommended. The physician will explain which treatment option is most appropriate, outline any contraindications, and answer all questions before anything is prescribed.
At BIOTOPE CLINIC in Shirokanedai, the team regularly sees international patients — expatriates, business travellers, and medical tourists — who appreciate the ability to discuss a sensitive health matter clearly in their own language without the communication barriers that can arise at general hospitals.
After Prescribing
For oral medications, the patient receives a prescription and typically a supply of tablets. Follow-up is recommended after 4–6 weeks to assess response and adjust dosage if needed. For ICI therapy, a supervised in-clinic training session is conducted before the patient begins self-injection at home, and follow-up visits are scheduled to review technique and dosing.
Who Is a Good Candidate — and Who Should Seek Further Assessment First
Most adult men experiencing persistent ED are candidates for an initial evaluation and, in the majority of cases, for oral PDE5 inhibitor therapy. There are no significant age restrictions for treatment.
Patients who should seek cardiology or general internal medicine clearance before starting ED treatment include those with unstable angina, a recent heart attack (within the past 6 months), severe heart failure, or uncontrolled hypertension. This is because sexual activity itself places demands on the cardiovascular system, and the interaction between PDE5 inhibitors and nitrate medications can cause a dangerous drop in blood pressure.
Patients with diabetes or neurological conditions that have caused more severe ED may find oral medications less effective and are good candidates for a discussion about ICI therapy as an alternative.
Common Misconceptions About ED Treatment
Misconception 1: “ED medication will cause an erection on its own.” This is a widely held misunderstanding. PDE5 inhibitors such as sildenafil and tadalafil enhance the body’s natural response to sexual stimulation — they do not cause an erection independently. Sexual arousal is still required for the medication to work. ICI therapy does produce a pharmacological erection regardless of arousal, which is part of why careful dosing and physician oversight are important.
Misconception 2: “Needing ED treatment means something is seriously wrong with your heart.”
While ED can sometimes be an early indicator of underlying cardiovascular issues (since both involve blood vessel function), the presence of ED does not automatically mean a patient has heart disease. A thorough consultation will help determine whether further investigation is warranted. For many men, ED has predominantly psychological or lifestyle-related causes that respond well to treatment without any cardiac implications.

Frequently Asked Questions
- Q. Can a foreign national be prescribed ED medication at a private clinic in Japan?
- Yes. Private clinics in Japan can prescribe ED medications (sildenafil, tadalafil) to non-Japanese patients provided a standard medical evaluation confirms it is safe to do so. National health insurance coverage does not apply, so the cost is paid out of pocket, but the prescribing process is straightforward at a private clinic with English-speaking staff.
- Q. Is it possible to get a same-day prescription?
- In many cases, yes. If the consultation is completed and no further investigations are required, a prescription can typically be issued on the same day. Patients with complex medical histories or those on multiple medications may need a brief additional evaluation first.
- Q. Is ICI (injection) therapy painful?
- Most patients describe the sensation as mild and much less uncomfortable than they anticipated. The needles used are very fine — comparable to those used for insulin injection — and the injection site is carefully selected to minimise discomfort. With proper training and technique, the procedure becomes straightforward for the majority of patients.
- Q. Will my consultation at BIOTOPE CLINIC be kept confidential?
- Yes. All medical consultations in Japan are subject to strict confidentiality obligations under Japanese law. Medical information is not shared with employers, immigration authorities, or third parties without patient consent. The clinic’s English-speaking team handles enquiries with full discretion.
- Q. Are there any non-medication treatments for ED available at the clinic?
- The men’s health menu at BIOTOPE CLINIC currently focuses on pharmacological treatment: oral PDE5 inhibitors and ICI therapy. The clinic also offers preventive and general wellness services — including nutritional (orthomolecular) therapy and IV drip protocols — that may support overall vascular and hormonal health. These are available to discuss during a consultation with Dr. Karibe.
