Using the ultrasound for therapeutic heat in PE

I was planning on starting a new log but have been way too busy with work, fixing things at home, family, etc. As such, I am also having a difficult time maintaining a steady routine.

In general, I had some issues getting the proper heat levels in the therapeutic range. I quickly learned that the digital “K” temperature scales are polarized and must be plugged in so the “+” symbol on the probe matches up to the “+” symbol on the thermometer base unit. (I purchased 2 models from different companies. One might work better than the other but need to test more first before commenting further).

So after a few tries I was able to go through a list of troubleshooting tips and was able to hit the proper temps by using my fingers to squeeze my shaft onto the US prob. Definitely felt uncomfortable on my fingers at times but I kinda ignored it or slightly moved my fingers. We do have a ton of nerve endings at the tips of our fingers…

After a few more tries, I used the “Crystal Clear Gorilla Tape” recommended by Igigi. I was a bit intimidated by the name of the tape but it works extremely well and it isn’t too bad to remove especially if I get it moist from gel, lube or water. The tape really held the K temp probs in place the entire session and this removed a big struggle I was having.

After 5 sessions, I am very good at using only one US probe to maintain temps above 40C as monitored by 2 separate K temp probes. I am able to get up to 43C and a bit beyond for a slit second. I definitely feel the heat and there are many times I must move the probe due to slight pain. (This was while in an extender for the first time and I have not tried to replicate this OTL yet, however, I like the extender better).

I am having a difficult time with the stress relaxation portion using a pulley, hanging weight and using a clamp to maintain a particular stretched length (particular stain length) and decided to test the extender.

I have removed the springs from my traction extender and am getting great results with stress relaxation. It is in this device which I have had the great success of achieving and maintaining the proper therapeutic temps.

The odd thing is that I am able to achieve the proper temps which I am in my extender and it is pointed straight out and I do not have any backing material for the US waves to bounce back on. (I was planning on putting a bag of rice or beans on my stomach for protection of the waves and then some Ultrasound phantoms followed by US gel, followed by the dorsal (back side) of my Dick which already has 2 K probs attached.

Is it okay that I can reach the temps when straight out in the extender with no backing material? I place the US prob on the Ventral (underside) of my Dick, with lots of US gel reapplications. It heats through my shaft to the dorsal side where I have 2 K probes taped. Then there is just air and no phantom and no flesh as backing, again, my dorsal side is just exposed to air.

Second question. Since the heating has been working well, when I finish the session, I remove the K probes from the dorsal side and apply the US prob to the dorsal side for 5 mins to try to heat the CS. Again, the ventral side is only exposed to air but the heat feels strong within.
Any feedback?

Thanks All

Great that you had it all started !

How uniform is the heat distribution?
I do mean that when moving away from the thermometer do you have a significant drop in the readings.
For getting non-biased readings I would recommend you to circle around not pointing too much direct exposure for the thermocouple.
In that way, you are more informed if the temperature elevation is uniform.
For the sake of uniform heat distribution, the phantom makes a real difference, as I am sure Rocco can confirm.

If you are experiencing your CS being tensioned and carrying the load then you should be targeting the heat also on it.
In any case, most of the load is carried by the dorsal side (from 10 o´clock to 2 o´clock) of the tunica which is the thickest and largest cross-sectional area of this bi-layered structure.

Certain cases like the famous restricting septum both Igigi and me have been molding with the heat make an exception.
Manko007 found the restricting element to be ventral thickening.

When connective tissue is stretched within therapeutic temperatures ranging 102 to 110 F (38.9- 43.3 C), the amount of structural weakening produced by a given amount of tissue elongation varies inversely with the temperature. This is apparently related to the progressive increase in the viscous flow properties of the collagenous tissue when it is heated. (Warren et al (1971,1976)

Thank You for the feedback. I am excited to have started and glad I have a decent understanding and time working with other PE techniques before I started the US Therapy. There is a lot involved.

I tape 2 temperature probs to the dorsal side. I try not to keep them in one place. I make small circles and keep them moving. Often I will just move the transducer up and down the ventral side slowly. Sometimes directly on the CS and sometimes slightly to either side. I tend to focus on either the top or bottom half for a few seconds, 10 seconds of smaller movement within a section and then move to the other half. It seems like the temp decrease might take about 30 seconds to decrease 2 degrees Celsius (this is a guesstimate from memory and would have to check during a session, however, I remember being happy that I could maintain good temp levels throughout my shaft.). The initial temp seems to hold for a few seconds before it declines after the transducer is moved away.

It took several rounds but it now seems easy to keep my entire shaft between 40-42+ degrees C.
I really think the solid and uniform tension being in the extender helped. I will try OTL again but really like the extender setup.

I will still add the phantom backing material. If there is potentially 60% of the energy lost to air, I would like to gain some of it back from the reflections off the phantom. I also want to prevent any adverse effects discussed earlier when we do not have a phantom or leg to reflect back the energy. I will make a small holder to help keep the phantom in place since the one I have seems slippery.
If the phantom further helps heat uniformly, awesome and I look forward to testing it out.

My Septum definitely seems to be my limiting factor. Just curious about heating from the dorsal side to hit the CS for a few mins. My CS is not well pronounced. I remember reading a post from Igigi in which he describes his CS being less pronounced and squished and when he used US to strain and lengthen his Septum, his CS had more room to express itself and it became fuller and more pronounced and produced some girth increase (hope I am recalling this properly. I was very intrigued when I read this…)

I stopped taking measurements pre and post. I would like to track and report measurements but it was becoming counter productive. I was wanking too hard and my Dick was becoming defensive and tightening up. I also started moving and rotating my hips to cheat the numbers. For now I will proceed like I play golf and not keep scope and just enjoy the process. I do feel like my Septum is being stretched and my Dick is more flexible.

I will certainly monitor temps and I have to purchase the recommended load cell and will monitor these metrics for sure.

When I can easily stretch to 8” BPFSL, I will know that the US Therapy has worked scientific magic.

Thanks Again for the Support and Sharing of Knowledge and Experience.

Since you feel comfortable with the setup and maintain the uniform heat, you should stick with the setup.
If you are not having control over the strain you should at least be cautious with the loading, not to exceed the necessary loads.

You do know the load profile of the extender springs? I thought you were testing the spring setup at some stage?

I have same “problem” with pre and post measurements and generally in PE measuring flaccid it tends to go like that.

I can confirm that I had quite homogeneous results with the Phantom at 4 measurement points. However, I cannot confirm whether it is worse without the phantom, since I did not perform any measurements here. But I assume it is. I had stabbing pain without a phantom - like little pinpricks - so the issue was quickly settled for me.
See also here about the measurement: US Phantom made of silicone

In the meantime I use IR from above to support the whole thing. The phantom is really very warm after a few minutes.

At least that’s how I had interpreted it by calling it “top five format”. But it doesn’t matter to me which ranking it has, that was only a joke. Everything you listed works and that counts.

@Stix + Trapezius

I assume that you both work in a 3 on / 2 off cycle. I measure the pre-BPFSL only once per cycle and preferably a few hours before the first workout of the three on-days. So I don’t have the problem with stiffening right before the workout anymore. Post-BPFSL, however, I measure after every workout. Since it can be assumed that the pre-BPFSL will increase by about 1 mm in these 3 days, the calculation error is small. I use the pre-BPFSL value from the first day for all three days to calculate the strain.

Thanks for all of the feedback from everyone.

I removed the springs from my extender to focus on stress relaxation. I have to purchase the proper load cell to get constant monitoring and not have the screen shut off after a few seconds. I will definitely start monitoring loads when I get the new load cell. I do understand the importance of less is more and I am one who tends to go with more as more.

Looking forward to testing the phantom to see if it helps even more and helps reflect more energy back into my Dick and helps prevent any of the safety issues mentioned early in the thread. I think the extender keeps more uniform tension on my shaft than I was achieving with OTL hanging. I never liked OTL hanging much and preferred other angles of attack. I feel like the uniform tension helps me heat up but I do want to try OTL again. I did not have the Crystal Clear Gorilla tape to secure the temperature probes when I was working the protocol OTL. This could have been an issue and I might have had an issue with the 4 port temperature meter as opposed to the 2 port unit I am having good success with (from a different company).

(The extender I have comes with some general loads based on the distance the springs are compressed. However, I want to avoid creep and really let my unit relax into the stretch.)

I have t had the time to be consistent with a 3 on 2 off schedule and it will be several weeks before I am able to be consistent. For now, I am performing the protocol when I can fit it in.

I do like the idea of measuring once per cycle as you mention. It seems like a good compromise to ease myself into.

In my honest opinion is its IMPERATIVE and SACRED to measure ALWAYS pre and post BPFSL RELIGIOUSLY. There is simply no way to create a detailed chart of progress, or there is no way to tell if the approach is being performed the right way. Measuring each time allows to tweak the protocol in order to improve strain.

Not to mention that a detailed log with detailed measurements allows each individual to always go back and repeat what worked the best. It is just like any sport or bodybuilding. You have to track weight, dimensions, size, symmetry, in other sports like track and field you strictly measure times, distances, etc. Always, no exception. This is the same. Is self discipline and commitment.

I do agree. I will try again.
It will be easier in a few weeks when
I am able to dedicate to a 3 on 2 off schedule.

I’m still trying to figure out all the small details to get it right. I am defined getting closer. It was a bit frustrating the first few sessions as I could not get over 39 degrees Celsius and I am now easily able to enter and stay in the therapeutic range.

I also want to add markers to the threads on my extender so I know the strain distance as well as the load.

Thanks for the push to keep it scientific.

I don’t share your opinion about pre-BPFSL. The pre-BPFSL does not change so much that missing two measurements should be dramatic. The way I suggest it, you measure before the first workout of a cycle and just don’t measure for the next two. So what?

Do the math yourself: If the pre-BPFSL changes by 1 mm within the three days, then that makes 0.5% at 20 cm BPFSL. Sorry, but that is within the scope of our measurement accuracy.
I prefer to accept the inaccuracy of the calculation instead of stressing the shaft too much before training.

As for the post-BPFSL, I’m right there with you, I would measure that after every workout. At least this way I can calculate the daily stretch with a possible error below 0.5% if I refer to the first pre-BPFSL of the cycle.

You can still log everything, but you take this small possible calculation error into account. I see no problem in this and still enough information for possible need for action. Just as an example: Whether you now have exactly 0.5% or 1% elongation is not so important. What is important is that you realize that you have to change something.

I can get some measurement with pulling 1kg force, orher with 2kg, other with 4 kg, some other with full force, let’s say 15 kg. If I do that it surely produces negative tissue responce. If I do it with light force, I cannot be sure if I pull with same force pre and post training when I do it manually by hand. Also I cannot say that I can measure my dick with millimeter precision.

When I see 5mm change then I can be quite certain that something has happened.

Going to try that what Rocco suggested, one pre measurement per cycle and done separately from workout. I would like to do that with some light controlled force instead of manually, because I want to minimize all pulling with cold dick and with great force. After measurements after every session.
