Any theories as to why some implants take way more pumps than others ?

Table 5 shows median #of pumps to full inflation for Titan implants 18 cm and up.
Median is 37, maximum 69.
They also state that one pump delivers “a little more than 2 cc’s”, which makes perfect sense with the pump’s volume being 2.5 cc since it would be practically impossible to squeeze 100% of the fluid out.
Which again raises the question why 125 cc reservoirs exist. If one pump delivers 2 cc and your theory of nobody needs more than 17 pumps is true, then maximum needed reservoir size is 34 cc. Tell me then why Titan has 75cc and 125cc reservoirs????

That is an interesting study. Re chart 5... in a way it addresses the whole point of this topic... why are there some men that only require 6 pumps but others that require 60 ? That is a huge variance even if one assumes smallest Titan versus largest Titan. I believe the study results are for real and that you are correct about your own experience...nonetheless the huge differences in pump numbers are also for real and my valve leakage theory was just one attempt to postulate why.

The study results make it even stranger that my implant surgeon out of hundreds of patients has never achieved more than 16 pumps.

Guys, I really don’t understand why you keep coming up with your theories and just keep refusing to see the obvious.

Before delivering another creative theory, explain - or realize the following:
Fact 1: the theoretical size of one pump is 2.5 cc.
Fact 2: 125 cc reservoirs exist and are frequently used.
Fact 3: if 17 pumps was the maximum, nobody would ever need more than 43 cc. Why then does a 125 cc reservoir even exist, and why do doctors use them?

As long as you don’t have a good explanation to this, why do you keep coming up with your theories?

So please tell me, what is it with the above you don’t agree with or understand?

Focusing on my point:

Fact 3: if 17 pumps was the maximum, nobody would ever need more than 43 cc. Why then does a 125 cc reservoir even exist, and why do doctors use them?

"if".

17 pumps is not the maximum.
Q.E.D.

It all depends on the size of the cylinders. Some rte's take inches away for longer cylinders. So lets say you have 18cm cylinders with a total with rte's of 22 cm in length. It would take approximate 22 full pumps to fill those cylinders. 60 does not make any sense unless you have a John Holmes.

If a guy only does shallow squeezes instead of full-depth squeezes, that would explain it, woudn't it?

Cylinder sizes in the study was 16-24 cm. Adjusting for fixed part of implant, inflatable lengths in the study was 11-19 cm. That alone does not explain the differences. But when adding differences in diameter between shorter and longer implants, we are at more than double the volume of the large ones.
Still, a difference between 6 and 69 is way more and as you say, hard to understand.
However, what I am saying is that I don't see the point of you trying to explain the normal (i.e. the average and the median results of the study) with some odd theories on leakage etc.
You cannot seriously believe that the normal situation is that the implant is leaking?
Go ahead and find conspiracy theories for the odd results, the 60+ and the >15. But for the normal results of 25-50, just accept the fact that that is the normal number of pumps it takes to inflate a larger Titan to the maximum.
And it corresponds very well with supporting data as pump size and reservoir size.
By the way, an 18 cm Titan in lab setting, i.e. not in a dick, takes around 30-40 pumps to inflate to max.

As for Lost, you chose a very good username at this site.

Good point Lost Sheep. Only my 1st squeeze is a full squeeze as the rest of my 15 to 20 squeezes are shallow.

Just a follow up that yesterday I started a cycle with full squeeze and the bulb wouldn’t reinflate for the next squeeze ! Stuck in the full collapsed position. Pressed relief valve and bulb back to normal but would do the same thing each time. Sooo I tried squeezing bulb maybe just halfway and it worked normally. Guess from now now I’m gonna squeeze less and pump more times ... ten or so seems to work.

As an aside, if not for posts here where others had temporary stuck valve issues that were easily resolved I would have been freaking out over that worried my system was down for good ! Thank goodness for this forum.
