Erectile Dysfunction Treatment in Miami, FL

What Is Erectile Dysfunction?

Erectile dysfunction (ED) is the consistent inability to achieve or maintain an erection sufficient for satisfactory sexual performance. Occasional difficulty with erections is normal and happens to most men. ED becomes a medical concern when it is persistent — occurring in more than 25% of sexual encounters — or when it is progressive, getting worse over time.

ED is not a diagnosis in itself so much as a symptom — often the first visible sign of an underlying condition that deserves attention. Understanding the cause of your ED is just as important as treating the symptom, because the underlying cause may have implications for your cardiovascular health, metabolic health, and longevity.

How Common Is Erectile Dysfunction?

Far more common than most men realize. The landmark Massachusetts Male Aging Study — the most widely cited ED prevalence study — found that:

• 52% of men between ages 40 and 70 experience some degree of erectile dysfunction
• 40% of men are affected at age 40
• Prevalence increases to nearly 70% by age 70
• Complete ED (total inability to achieve erections) increases from 5% at age 40 to 15% at age 70
• An estimated 30 million American men have ED
• Only 25% seek treatment — leaving approximately 22 million men untreated

ED also affects younger men more frequently than commonly believed. Studies suggest that 8-10% of men aged 20-29 and 11-15% of men aged 30-39 experience some degree of erectile difficulty, often driven by performance anxiety, medication side effects (particularly SSRIs), or early metabolic dysfunction.

Causes of Erectile Dysfunction

An erection is a complex vascular, neurological, and hormonal event. Disruption at any point in this chain — from the brain signaling arousal to blood vessels dilating to smooth muscle relaxing — can produce ED. Most cases involve a combination of factors.

Vascular Causes

Vascular disease is the most common physical cause of ED. Erections depend on robust arterial blood flow into the penis and effective venous restriction to maintain engorgement. Conditions that damage blood vessels impair this process:

• Atherosclerosis — plaque buildup in arteries reduces blood flow. Because penile arteries are smaller (1-2mm) than coronary arteries (3-4mm), they clog first. This is why ED often precedes heart attack or stroke by 3-5 years
• Hypertension — damages the endothelial lining of blood vessels and reduces nitric oxide availability
• Diabetes — damages both blood vessels and nerves. Up to 75% of diabetic men experience ED
• High cholesterol — contributes to atherosclerosis and endothelial dysfunction
• Obesity — associated with endothelial dysfunction, low testosterone, and increased inflammatory markers
• Smoking — damages blood vessel walls and reduces blood flow. Smokers are approximately 50% more likely to develop ED

Hormonal Causes

Hormones — particularly testosterone — play a critical role in both sexual desire and the physiological erection process:

• Low testosterone — reduces libido and impairs nitric oxide synthesis and smooth muscle function in penile tissue. An estimated 25% of men over 30 have clinically low testosterone
• Elevated estrogen — excess estradiol (often from aromatization of testosterone in overweight men) can suppress sexual function
• Thyroid disorders — both hypothyroidism and hyperthyroidism are associated with ED
• Elevated prolactin — can suppress testosterone and sexual function

Neurological and Structural Causes

• Spinal cord injury or nerve damage
• Multiple sclerosis, Parkinson's disease
• Pelvic surgery (prostatectomy, colorectal surgery)
• Pelvic radiation therapy
• Peyronie's disease (scar tissue in the penis)

Psychological Causes

Psychological factors are the primary driver of ED in younger men and a contributing factor at all ages:

• Performance anxiety — the most common psychological cause, creating a self-reinforcing cycle where fear of failure leads to failure
• Stress — chronic work or life stress elevates cortisol, which suppresses testosterone and sexual function
• Depression — both the condition itself and many antidepressant medications (SSRIs, SNRIs) impair erectile function
• Relationship issues — conflict, lack of emotional intimacy, and communication breakdown

Medication-Induced ED

Many common medications contribute to or directly cause ED:

• Antidepressants (SSRIs like sertraline, paroxetine, fluoxetine)
• Blood pressure medications (beta-blockers, thiazide diuretics)
• Finasteride / dutasteride (for hair loss or prostate)
• Opioid pain medications
• Antihistamines
• Benzodiazepines
• Excessive alcohol

If you suspect a medication is contributing to ED, we can evaluate alternatives or adjunct treatments. Never stop a prescribed medication without consulting your healthcare provider.

ED as an Early Warning Sign for Cardiovascular Disease

This may be the most important section on this page. Erectile dysfunction is not just a quality-of-life issue — it is a vascular health marker.

Because the penile arteries are significantly smaller than coronary arteries, atherosclerotic plaque accumulates there first. Research published in the European Heart Journal found that men with ED have:

• A 59% increased risk of cardiovascular disease
• A 74% increased risk of coronary heart disease
• A 33% increased risk of stroke

ED typically presents 3-5 years before a major cardiovascular event. This means erectile dysfunction can serve as an early warning system — a window of opportunity to identify and treat cardiovascular risk factors before a heart attack or stroke occurs.

At Rewind Anti-Aging, we don't just prescribe an ED medication and send you home. We evaluate the vascular, metabolic, and hormonal factors driving your ED — including lipid panels, fasting insulin, hemoglobin A1c, inflammatory markers, and blood pressure — because treating ED properly means treating the whole patient.

Treatment Options at Rewind Anti-Aging of Miami

PDE5 Inhibitors (Oral Medications and Custom Compounds)

PDE5 inhibitors are the first-line treatment for erectile dysfunction. They work by blocking phosphodiesterase type 5, an enzyme that breaks down cyclic GMP — the molecule that relaxes smooth muscle in the penis and allows blood to fill the erectile chambers. They require sexual stimulation to work and do not produce spontaneous erections.

Standard Options

• Sildenafil (Viagra) — onset 30-60 minutes, duration 4-6 hours. Best for on-demand use. Effective in approximately 70% of men
• Tadalafil (Cialis) — onset 30-60 minutes, duration up to 36 hours. Also available as a daily low-dose (2.5-5mg) for continuous readiness without planning. Effective in approximately 70-80% of men

Custom Compound Blends

Where Rewind goes beyond standard prescriptions. Our compounded formulations combine PDE5 inhibitors with additional active ingredients for multi-pathway efficacy, delivered as sublingual troches (dissolved under the tongue) for faster absorption:

• Sildenafil + Oxytocin — combines blood flow enhancement with oxytocin's arousal, bonding, and anti-anxiety effects
• Sildenafil + Testosterone — PDE5 inhibition plus direct testosterone support for desire and erection quality
• Tadalafil + Testosterone — long-acting PDE5 inhibitor with hormonal support
• Tadalafil + Oxytocin + Sermorelin + Testosterone — our most comprehensive compound, combining blood flow optimization, hormonal support, growth hormone peptide, and neuroendocrine enhancement

Injectable Therapy: BiMix, TriMix, and QuadMix

For men who do not respond adequately to oral medications — or who want the most reliable, powerful erectile response available without surgery — intracavernosal injection therapy delivers medication directly into the penile tissue. This is the most effective non-surgical ED treatment.

BiMix

A two-ingredient compound containing papaverine (a vasodilator) and phentolamine (an alpha-blocker). BiMix produces a full erection within 5-15 minutes of injection with an efficacy rate of approximately 80%. It is a good first-line injectable option for men transitioning from oral medications.

TriMix

The gold standard in injectable ED therapy. TriMix combines alprostadil (a prostaglandin that dilates blood vessels), papaverine (a vasodilator), and phentolamine (an alpha-blocker). These three compounds act synergistically — increasing arterial inflow, dilating smooth muscle, and restricting venous outflow — to produce firm, reliable erections with greater success and in smaller individual doses than any single agent alone.

TriMix has an efficacy rate of approximately 85-90%, including in men who have failed oral medications. Onset is within 5-15 minutes. Duration is typically 30-90 minutes depending on the dose. TriMix has transformed the sexual lives of many men with severe ED who thought they were out of options.

QuadMix

For the most treatment-resistant cases. QuadMix adds atropine to the TriMix formulation, further enhancing smooth muscle relaxation and venous restriction. QuadMix has been reported to produce erections in effectively 100% of men seeking ED treatment — making it the last-resort injectable before considering surgical options.

Self-Injection: Simpler Than You Think

We understand that the idea of penile injection causes anxiety for most men. The reality is far less daunting than the concept:

• We use ultra-fine 29-31 gauge insulin syringes — the same needles diabetics use for insulin, which cause minimal discomfort
• Injection is into the side of the shaft (corpus cavernosum), avoiding the dorsal nerve and urethra
• Most men describe a brief pinch lasting about one second
• We teach you the complete technique in our office and supervise your first injection
• Most patients are comfortable self-injecting within one or two attempts

Testosterone Optimization

Low testosterone is often the underlying driver of both erectile dysfunction and low libido. Testosterone supports nitric oxide production, smooth muscle health, and neural signaling in the erectile pathway — in addition to being the primary hormone driving sexual desire.

Through hormone replacement therapy, we restore testosterone to optimal levels. For many men, testosterone optimization alone resolves or significantly improves ED. For others, it enhances the effectiveness of PDE5 inhibitors or injectable therapy — often allowing lower doses of those medications to work more effectively.

We test total testosterone, free testosterone, SHBG, estradiol, and related markers to understand your complete hormonal picture before designing a treatment protocol.

PT-141 (Bremelanotide)

PT-141 works through an entirely different mechanism than any other ED treatment. Instead of targeting blood flow (like PDE5 inhibitors or injectables) or hormones (like testosterone), PT-141 activates melanocortin receptors in the brain — directly increasing sexual desire and arousal at the neurological level.

This makes PT-141 particularly valuable for men whose ED has a significant desire or psychological component, or who want to enhance both the mental and physical aspects of sexual function. It is administered as a subcutaneous injection approximately 45-60 minutes before sexual activity and can be used alongside PDE5 inhibitors or injectable therapy.

When to See a Doctor About Erectile Dysfunction

Many men delay seeking help for ED due to embarrassment. But given what we know about ED as a cardiovascular marker and its impact on quality of life, earlier evaluation is always better. You should schedule an evaluation if:

• ED occurs in more than 25% of sexual encounters
• ED is getting progressively worse over weeks or months
• ED appeared suddenly — which may indicate a vascular event, nerve injury, or significant psychological trigger
• ED is accompanied by other symptoms — fatigue, weight gain, mood changes, or reduced morning erections (suggesting low testosterone)
• ED is causing relationship distress or significantly reducing your quality of life
• You have cardiovascular risk factors — diabetes, high blood pressure, high cholesterol, smoking, family history of heart disease — and ED may be your body's earliest warning

Our Approach to ED Treatment at Rewind Anti-Aging

1. Confidential consultation — we discuss your sexual health history, symptom onset and pattern, medical history, medications, lifestyle factors, and goals in a private, judgment-free setting
2. Comprehensive blood panel — total and free testosterone, estradiol, SHBG, PSA, thyroid panel, CBC, CMP, lipid panel, fasting insulin, hemoglobin A1c, and inflammatory markers. We evaluate both the direct hormonal causes of ED and the metabolic and cardiovascular factors behind them
3. Root-cause identification — is it vascular, hormonal, psychological, medication-related, or a combination? The answer determines the right treatment approach
4. Personalized treatment plan — we match the treatment to your specific situation. Some men need testosterone optimization alone. Others need custom oral compounds. Some require injectable therapy. Many benefit from a combination. We start with the least invasive effective option and escalate only as needed
5. Follow-up and optimization — ED treatment requires fine-tuning. We follow up to assess results, adjust medications and dosing, and ensure you are getting the outcomes you want
