Service life - 20 year study

[Lost Sheep]

I found this article. Haven't read it yet, but the title seems VERY promising to yield useful information about service life expectancy and perhaps modes of failure.

Long-Term Survival of Inflatable Penile Prostheses: Single Surgical Group Experience with 2,384 First-Time implants spanning two decades.

Excellent study, well worth the read

Thanks for sharing.

I am pasting the Conclusion here :

Long-term revision-free survival for inflatablepenile prostheses is probably the highest of any medical devices currently implanted in humans. We estimated that 60% of historic virgin penileimplants survived 15 or more years without revi-sion or extraction. So far, our shorter-term track-ing of devices that have been enhanced to diminishmechanical breakage and infection predicts evenbetter improvement in the 15-year survival for Mentor Titan and AMS 700 CX.

yes, this is grreat great news, implants can last easily 15 years !!!!!!


woo hooooooo

thanks for the reference, thrilled to see it.

also great to see how satisfied the majority of patients are !

I figured given all the recent discussions about the varying lifespans of each model of implant it would be helpful to post the individual mechanical survival rates by each type of implant.

It is especially worth noting that this study was published in 2007, and contains data going back 20 years before that. As a results the exact implant models discussed in this study are not even currently on the market.

The AMS 700 CX is the only model that is still on the market in name. However, there have been improvements made to the modern AMS 700 CX's that were not present in the older CX models used in this study. For example, the Parylene coating introduced to the AMS 700 CX in 2000 has contributed to notably longer survival rates when compared to models before 2000.

The AMS 700 Ultrex listed in the study was later replaced by the AMS 700 LGX. This is not simply a case of name change, the LGX is the successor of the Ultrex, and while there are similarities in their designs, the LGX is expected to be more durable than it's predecessor. The LGX also features the Parylene coating that was originally introduced for the AMS 700 CX in 2000.

For those who are unaware, the company Mentor was bought by Coloplast in 2006, so the Mentor Alpha I is the predecessor of the modern Coloplast Titan. Unfortuantely I haven't been able to find any information about whether the Coloplast Titan has been significantly altered from the old Mentor Alpha I design. I know that the design of the pumps has changed since the publication of this study, but I am unaware of any innovations regarding the cylinders of the Titan have been made.

AMS 700 CX
1 year 96.3 (94.3, 97.6)
5 years 85.2 (80.5, 88.8)
10 years 67.7 (60.6, 73.8)
15 years 57.0 (47.5, 65.5)

AMS 700 ULTREX
1 year 96.5 (86.7, 99.1)
5 years 74.3 (60.5, 83.9)
10 years 61.5 (45.8, 73.8)
15 years No Data Present

MENTOR ALPHA I
1 year 98.1 (97.3, 98.7)
5 years 89.9 (88.2, 91.4)
10 years 82.1 (79.5, 84.4)
15 years 76.2 (70.1, 81.2)


It is clear from the data that while the survival rates of the different models are comparable, the Mentor Alpha I has a significantly higher mechanical survival rate than the CX or Ultrex, and the CX sits comfortably above the Ultrex in terms of reliability. If we were living decades ago, I think the data would indicate that the Mentor Alpha I would clearly be the most reliable choice of implant for a man to get.

Unfortunately, we can't directly compare these study results to the more modern implant models that most of us have. However, if we assume that the rates of mechanical survival for the different models roughly correlate with the modern successors, the Titan would be the most reliable, followed by the CX and then the LGX. Of course, improvements have been made to both the CX and the LGX models since the old CX and Ultrex days, so while the CX was more reliable decades ago, it's very possible that the new design of the LGX has the modern CX matched in terms of lifespan. And the improvements such as Parylene coating may very well bring the mechanical survival rates of modern AMS 700 models up to (or surpassing) the level of the historical Alpha I.

Ultimately, I would say the results of this study are very positive, as even the least durable implant, the AMS 700 Ultrex, (which has since been succeeded by the supposedly superior design of the LGX) still has a 61.5% chance of being functional at 10 years.

Given that improvements have been made the modern AMS 700 CX and AMS 700 LGX models, (And I believe the Titan has certainly seen some improvements from the Mentor Alpha I days) I think it is safe to say that modern implants should have an even greater chance of being functional at 10 years.

Idk guys. Don’t mean to be a buzzkill, but I’ve had 2 failures in less than 2 years.

About to have my 3rd Revision. I’m trying to keep the faith, but I believe the devices are pieces of shit. Try to stay positive, but all I’m reminded with are failed rigs.

I hear you. Even the best manufacturers will produce a "lemon" once in a while. I wonder if your three failed implants were the same model, implanted by the same surgeon and if the modes of failure were the same or different?

Some failures are tubing connectors, some are due to pump or valve failures, some are due to the implant body itself, leakage in the reservoir and other miscellaneous causes.

Have you discussed with your surgeon or the manufacturer(s) what the cause might be (if there is one) of the string of failures that have visited themselves on you?

Do their explanations satisfy you enough to trust to another implant with the same model tried before, switch to another manufacturer or model or (how close are you to considering the option to) pass on an implant (and sex) altogether?

It's the genesis pump. I've read in a couple places where the latest iteration of that pump was not made correctly. Dr. Hakky and Dr. Perito favored that pump because of it's reputation for dependability. They no longer use it from what I understand. I think 1Roofer has just had a run of bad luck.

The Genesis pump was the failure of the initial installation & was the failure on the pump revision. I’m going in for my 2nd revision on June 9th. Yes perito & Hakky both said that the Genesis pump systems have recently been weak manufactured products. Also, Hakky states that Perito is not installing Genesis pumps in young guys anymore. Coloplast Director of Medical Affairs, Dale Klous, says that there has been some issues which is why my next revision is free & Hakky is doing my next complete install free of charge. I’m getting a new 22cm or larger, but using the One Touch pump.

I talked with Dr Wilson who was the number one leader in penile implants in the world who has installed over 11,000 penile implants & he said that both of my failures should’ve have never occurred during sex which was their demise. I rock climb, CrossFit, climb roofs, but my failures were from sport fucking with my penile implant inflated. Seems like some weak shit regardless

Regardless, I still think there is a case for it being mechanical and the more often it’s used.....well who knows?
Mine is used 6/7 days a week....so 10 years might be a great outcome
