Eight years of trying.
One surgery that worked.

I went through every treatment option — pills, injections, shockwave. I tracked my bloodwork the whole time. Eventually I had a penile prosthesis implanted in 2022. This is what I wish I'd known earlier.

Why ED happens — and why it’s almost always physical

The biggest misconception about erectile dysfunction is that it's psychological. For the vast majority of men over 40, it's vascular, hormonal, or neurological. Your body is sending a signal. The question is whether you read it — or ignore it for another decade.

Most common
Vascular restriction
Blood can't fill the corpus cavernosum fully. Often the first visible sign of cardiovascular disease.
Very common
Low testosterone / high SHBG
Low free T kills libido and erection quality. SHBG binds your testosterone so your bloodwork looks normal — but it isn't.
Common
Nerve damage
Diabetes, prostate surgery, and spinal conditions can damage the nerves that initiate erection.
Less discussed
Venous leak
Blood flows in but doesn't stay. An erection starts and fades quickly. Often misdiagnosed as psychological.

The treatment ladder — in order

Treatment typically follows this sequence. Most men start at tier one and work their way up. I spent eight years across the first three tiers before making the decision that actually solved it.

Tier 1
💊
Oral medication
PDE5 inhibitors. Low-intensity solution. Results are often weak, brief, and unreliable — and dosage dependency develops quickly.
Tier 2
💉
Injection therapy
Directly injected vasoactive drugs. Higher success rate. Requires consistency and nerve.
Tier 3
⚡
Shockwave / ESWT
Low-intensity shockwave promotes vascular regeneration. Results vary widely by patient.
What I chose
Tier 4
🔧
Penile prosthesis
Surgical implant. Highest satisfaction rate of all ED treatments. Permanent solution.

What is a penile prosthesis?

A penile prosthesis is a surgically implanted device that replaces the natural erection mechanism. There are two main types: malleable (semi-rigid) and inflatable. The three-piece inflatable is the standard for most men — and the one I have.

The device is entirely internal and concealed. From the outside, no one can tell. Appearance is completely normal when not in use, and fully functional when activated.

The device I chose

The Coloplast Titan is the three-piece inflatable device I have. You inflate it manually via the scrotal pump, and deflate when done. Appearance is completely normal at rest — no visible difference, no external hardware. The decision to go this route was the best medical decision I've ever made.

“I spent eight years feeling like something was wrong with me as a person. Turns out something was wrong with my blood flow. Once I had the surgery, I stopped thinking about it entirely. That's not a metaphor — I literally never think about it anymore. That's the bionic super-power nobody talks about.”

The hormonal piece

The prosthesis solves the mechanical problem. But hormones run everything upstream. My testosterone was at 380 ng/dL in 2018 — low-normal by standard lab ranges, but nowhere near optimal. Tracking SHBG alongside total T revealed the real picture: my free testosterone was even lower than my bloodwork implied.

Today my total T sits at 850 ng/dL — not from injections, but from a disciplined supplement and lifestyle protocol. The bloodwork page has the full breakdown.

What’s worth knowing before you decide

These are the six things I wish someone had told me clearly — not in medical jargon, not buried in a research paper.

1
It's irreversible — and that's okay The implant removes the ability to have a natural erection. For men who already can't, this isn't a loss. It's a trade: uncertainty for reliability.
2
Surgeon experience matters more than the device The device is secondary to who implants it. Volume matters. Ask how many procedures your surgeon performs per year. Hundreds, not dozens.
3
Satisfaction rates are genuinely high Penile prosthesis surgery has one of the highest patient satisfaction rates in all of urology — consistently above 90% in published studies.
4
The timing conversation is real Waiting too long after severe ED can affect surgical outcomes. The tissue atrophies. Earlier is often better if other options have failed.
5
Partner communication changes everything Men who had this conversation openly with their partner before surgery consistently reported better outcomes. Don't carry it alone.
6
You will stop thinking about it The mental load of ED is enormous and invisible. Post-surgery, most men report that the psychological relief was as significant as the physical result.

If you’re considering this — talk to me first.

I'm not a doctor and I won't give you medical advice. But I'll tell you exactly what I went through, what I asked my surgeon, and what I would do differently. No agenda, no sales pitch — just a real conversation from someone who's been there.
