Using the ultrasound for therapeutic heat in PE

Nobody knows. The effect is not miraculous even having ED. There are non-responders as well.

Shockwaves have been found to cause collagen degradation on healthy connective tissue so reflecting on that, it is not recommendable to use it on perfectly healthy unit at all.

I’m interested in getting started with Ultra sound and would really appreciate some wisdom on the differences between the two types of machine that seem to pop up on eBay . There are ones with some kind of station, which tend to be priced over £100 and made in India, and ones which appear to have the interface on the handheld device, with no station. Not only are these cheaper (seen one for £66), but it looks more user friendly and convenient. Most people I’ve seen on here seem to have gone with the station-based Indian ones. Do the handhelds work just as well?

Surely if the equipment is sufficient enough.
There are certain specs the machinery must meet. And you can find it on this thread.

Minimum of 1.5 w/cm ^2
1 MHz or 3 MHz operating frequency.
ERA (effective radiating area) 4- 5 cm^2
BNR(beam non- uniformity ratio) 5: 1 or less.

And you cannot find such a device at 60-100 $ bracket.

Thanks for the response kyrpa. The £66 device is 3mhz and lists it’s stats as:
Low: 2.3W/cm2 and High: 4.8W/cm2

BNR: 1.74

ERA: 7.06 cm2

Not exactly sure what the 1.74 BNR denotes, but it would work out at a ratio of just under 2:1.

To be honest I should stop being lazy and read your initial posts to work out what BNR is and then make a judgement from that point.

Right. I’ve had a read and understand that 1.74 probably is too high. None of the other machines seem to specify BNR though.

1.74 w/cm^2 you mean?

If so it suits just fine if it has option for 100% duty cycle.
We have examples of guys running 2- 2.5 w / cm^2.
It starts to get intolerable going higher.
Also the limit comes sooner with 3 MHz.

With all decent machinery the BNR is provided.
I wouldn’t purchase any machine without knowing.

BNR is crucial for the user safety.
It is Pretty much mandatory in western medical field.

It tells the ratio between the average intensity and peak intensity bursts the transducer produces.

Using low intensities 6:1 is the maximum, the older high end machinery has such numbers.

In modern machinery 5:1 can be considered fine ratio.
High end machinery having 3:1 ratios.

8:1 or more has been labeled harmful.
This is the greatest concern with cheap machinery. It can be unsafe to use it.

Ok. Didn’t catch this post earlier.

To be honest it is hard to believe BNR being true.

Having such a large ERA it means it has a circle of 3cm diameter which has to be in firm contact with the penis all the time. It can make the usage difficult unless you have really thick penis at flaccid state.

Would you link it?

Thanks again for you responses Kyrpa. Here is the link:

An interesting piece of equipment.

I would love to see the manual, as the sellers often cherrypick the numbers, let’s say creatively.

I do believe their numbers are plain bullshit.

The numbers and the price tag do not match.

I think their output numbers are in real life

2.4 w total output which correlates to 0.4 w/cm^2 and 4.8 w total output correlating to 0.8 w/cm^2
Also, they don´t tell in which duty cycle the outputs are told.
If the machine does not provide a full 100% Duty cycle it is useless anyways.

And the BNR has to be a straight out lie.

I’m inclined to agree with you. I think I’ll order the US pro 2000 2nd edition, since you and others have found this to be very effective.

I have a question about measuring. Presumably everybody should measure the penis temperature whilst using ultrasound to know when the 40 mark has been reached. But does this need to be done with a urethral probe? If not, what device should be used and will it give an accurate indication of temperature?

There are plenty of examples of guys using thermocouple pairings with digital thermometers outside the shaft.
We have found a close correlation between urethral probe readings and thermocouples placed between the shaft and thigh when heated in the OTL stretch.
The accuracy stays inside a one degree Celsius margin.

I really encourage you to read this entire thread first.
You can see who is on the protocol and how they do it.
Many of us have really a lot of informative posts on our individual logs.
This is a topic you can not learn too much about. Both safety and efficiency-wise.

You’re absolutely right and I am in the course of reading all the different threads about ultrasound right now. Unfortunately some of the more technical aspects are lost on me. I had read the study you did on external vs internal measuring but I had no idea what thermocouple or many other words used meant which is why I was confused (I don’t mean to criticize your research or writing, obviously you are doing a great service). Understanding this now, I still just want to clarify one thing. When measuring with a thermocouple wire, is it just the tip of the wire that measure the heat, or is it the whole wire? Ie. do I need to squeeze as much of the wire as possible between my leg and my penis or just hold the tip in place there.

That is with just one US 2000 pro 2nd edition?
