What do we know about penis valve damage?

Have we figured out anything on this board about potential valve damage to the penis from PE - particularly from squeezes, which might force the blood against the valves the wrong way?

There’s a series of valves that close to seal off the blood from leaving the penis - that is what causes an erection.

I do squeezes while clamped, so there’s a good amount of pressure being applied.


*I measure PRE-WORKOUT, normal erection* Started: 7 EBP x 4.9 EG. Several years on and off PE, now 8.125 EBP length x 5.5 EG midshaft (5.8 base). Working on girth (clamping) again after breaks due to injuries - fast recent gains! Pics

Leaky valves can cause erectile dysfunction, in other words. It does happen.

If you are experiencing leaky valves I would imagine you are using way to much pressure between clamping and squeezing. You don’t want to cause an injury.


sunny A day without sunshine is like a day without laughter :sun:

I am not necessarily experiencing it - I am just wondering if anyone has any knowledge about the potential of PE in general, and squeezes in particular, to cause valve damage.

There are no such valves in the penis, like there are in, say, the veins in arms and legs which stop the back-flow of venous blood.

What causes an erection to keep going is the increasing pressure of the tunica (as the CCs expand) against the veins which carry blood out; this almost seals them off.

Venous Leakage is another animal and not related to valves.

There are three venous drainage systems in the penis: They are the superficial, intermediate and deep systems. (I will ignore the deep system because the large vessels are found mainly in the pelvis where they drain the cavernosa and the spongiosum)

The superficial vessels of the penis do not have valves which is advantageous because blood flow in the these veins gets jerked around during intercourse. BTW, it appears that in some guys, there are occasionally small branches that drain parts of the scrotum, but they are not common (see attachment 1).

The intermediate venous system includes the deep dorsal vein and the circumflex veins. The deep dorsal vein runs in the groove between the two cavernosa. It can exist as a single large vessel. In some guys there are a few smaller branches that run with the larger deep dorsal vein. There are between 3 - 8 valves in the larger deep dorsal vein. The circumflex vessels run circumstantially from the bottom (or ventral) portion of the penis and drain into the deep dorsal vein(s) (see attachment 2).

The penis is designed to stand up to the rugged nature of intercourse. In many animals, intercourse is a short very aggressive act with marked penis stresses (maybe in some of us guys as well). The deep dorsal vein, where the only known valves have been found, in the exposed portion of the penis, are quite distensible. In addition. with the circumflex draining into them, blood from the deep dorsal vein has the capacity to back flow into the circumflex veins. The circumflex veins by their circumferential arrangement are not affected by base to head (or head to base) longitudinal stress (intercourse, masturbation, jelqing). Therefore back flow into them from the deep dorsal vein and distensibility relieves pressure that might otherwise push against and damage the valves.

If you are so aggressive that with your jelqing or squeezes are so aggressive that you get close to damaging the valves, I guaranty you will do other damage as well. Over aggressive PE is not recommended and should be avoided.

While I’ve absolutely had no symptoms of this, I’ve wondered about the possibility of this happening.

What about valves in the kidneys or elsewhere. I’ve sometimes had pains in my kidney area, however I can’t say positively that it wasn’t pulled muscles from exercising.

There are no valves to the renal vein emptying the kidney.

Valves are found in veins that are generally in the arms and the legs where blood must flow “up hill”. the valves keep the blood from pooling in the ankles and hands. As the blood moves up, the valves keep it from dropping back.

How about the deep system?

In extremities it’s the most important pathway.

The deep venous system is definitely important. The deep system empties the majority of the blood from the penis. The vessels draining the expanded sinusoids of the cavernosa (called the emissary veins) from the end 1/3 of the penis (the entire penis including the unexposed penis; so it is the distal 1/3) feed into multiple small cavernosa veins. These smaller cavernosa veins ultimately unite into 1 or 2 larger main cavernosa vein(s). This (or these) main cavernosa vein(s) form after the penis enters into the body (the unexposed penis). There are 1 - 4 valves in this (or these) main cavernosa vein(s), but they are located deep in the pelvis where PE cannot affect them. This why I ignored them.

I am pretty much new to PE besides knowing how to kegel previously. My glans has always been very defined and hard. After a week of PE I noticed gains in length and width so I intensified my workout getting ambitious about further potential before reading into the possible consequences.

In my second week I was warming up, jelqing, kegeling, and stretching. One session in particular was very intense repeating jelqing and squeezing forcing large amounts of blood into the glans when I was erect. I had no pain but some small spots on the shaft afterwards. Since that day my erections have been harder in the shaft but my glans is completely soft and smaller! Taking three weeks off has not solved the problem and I am hoping I did not do serious damage. The only time I can get the glans even semi hard is to tilt the penis down and put pressure from underneath the shaft forcing blood in. As soon as I take my hands off though it goes back to being small and soft. This is not a mental issue as I have pictures of my penis before PE and the head is much larger and I remember it being more firm. It specifically occurred after that session and my morning wood has gone away.

Is this possibly a valve damage injury? Or leakage in deep tissue? Can anyone help me with any advise or knowledge about this problem. I really hope my head doesn’t permanently stay like this because it really makes my penis look funny, smaller, and not very attractive. Thanks.

Could PE indirectly affect these valves?

Would severing the superficial dorsal vein during penis lengthening surgery cause a venous leak, or would the vein eventually seal off or fuse? I’ve had short lived erections for the longest time after surgery.Viagra helps but I’ve been trying not to rely on it.Doppler flow voids have been within normal limits, a few years after surgery,but I don’t know if borderline normal would isolate SDV involvement?

I know and have read in other posts that the deep dorsal vein is responsible for the majority of venous outflow,but does the superficial dorsal vein play a role in any emission of the CC or the glans?

I’ve googled SDV and regular vein severence with no answers so I thought I would post in a thread related to venous leaks/damage.Thanks .

Can anyone clear the question if there are valves in the penis or not?

If yes, read the following:

My erection has gone worse over the years. I am doing jelqing in a medium-strong way to enhance girth since everal years now, with interruptions.

This information is enough for me to go from jelqing as a girth exercise down in intensity to jelqing as a warm-up exercise.
I was thinking about this valve leakage issue very often and IF there are valves in the penis, no matter how deep they are in the penis, they can be attacked by the stroke we apply against the stream of blood during jelqing.
Maybe mild jelqing doesnt affect these valves severely, but since no one can tell me which pressure could be applied as a maximum since no one knows my body and there is no exact data I wont take a risk. There are too many unknown facts:

-how deep do veins have to be in the penis to be not affected by jelqing
-how strong may the strokes be
-how strong should the erections be while jelqing since a harder penis would protect the inner veins much better
-how long jelqing, how often….

All very unknown data..one thinks this, one thinks that. There are too many “maybe”s and to many “in my opinion”s. I wont go back to REAL jelqing as long as there is no evidence for its safety.

There is successful PEing stated in PUBMED by this Penimaster or whatever it is called and so I will go from jelqing+hanging to only hanging since there seems to be much less risk. If you apply a mild force over the whole day (hanging + ADS) there should be more benefit.

Keep in mind that jelqing as a girth exercise cant be distributed over the whole day like using an ADS so the force you apply has to be stronger since the time span you apply the force is much shorter. Otherwise its just not effective. Of course you can try to find a compromise, but is it worth the 30 minutes of medium-intense jelqing, maybe twice a day, to get some girth gains, still always having thoughts about a potential ED in the backhead?

Jelqing is not multi-taskable like hanging, this is another con.

Ok, to keep it focused: Jelqing just seems either kind of dangerous or ineffective. I dont want to panic. But is jelqing really necessary as an exercise if you are not specifically going for girth?


My goal: from 11.9 cm NBPEL to 18 cm NBPEL (~7 ") ...now or never...!!!! after 5 weeks(and a long break): 12.5 cm NBPEL
