Ball Pumping and Fertility

Ball Pumping and Fertility

I’ve seen a couple of messages around the net where people mention ball pumping possibly causing sterility. I am reluctant to believe this, since there is really no good definitive source on ball pumping on the net, and I doubt whether these people actually know what they are talking about. To me, most of it seems to be heresay.

So what do you all think? I would think that doing a little expansion of the testicles with some vacuum wouldn’t do any permanent damage if it even does any damage at all. And even if it did, the body has a remarkable way of healing/regenerating itself.

I’m also wondering if pumping might actually help fertility. I mean, after all, you are providing additional stimulation to the testicles.

I would appreciate any feedback from anyone who is experienced with this. So here’s my question. Have any of you guys who are routine ballpumpers knocked up your wife or your girlfriend while (or after) you were pumping?

Thanks for the input.


Sorry, I can’t give you any definite input from my end. I didn’t get into ball pumping and dick pumping until well after my two daughters were born. My personal opinion is that if you aren’t abusing your dick with pumping, you should probably be okay. Anybody else?


Ball stretching didn’t prevent me from having a son. I have pumped my balls using a jar a few times, but that was after he was conceived. I doubt that, if done in moderation, you’d have any long-term problems.

I did it out of curiosity, and found it to be a lot more fun than penis pumping. One of these days, I’ll pump them up and see if my wife notices. :p

Did a fair amount of ball pumping before knocking up the wife… TWICE. I almost always ball pumped using hot water in the tube.

By the way, you can get the balls pretty huge and it is fun to see the wife react a little. I found I shot really big loads shortly after pumping the balls.

Do the nuts actually get bigger, or is it just fluid build-up in the scrotum?

Both, but they eventually return to normal. I’ve been pumping 1-2 hours/day every day for at least two weeks and haven’t had an appreciable build-up of fluid. I have noticed that my scrotum stays pink and warm and hangs low all the time, so pumping evidently improves circulation.

Warning: ball pumping is addictive.

If you ball pump for extended period of time ( hours) then you definitely build up fluid. But, if you pump for a shorter period of time (30-60 minutes), the testicles themselves actually do get quite a bit larger. It is VERY cool.

I just started, and my balls got bigger, and I would say they have stayed larger for 1 to 2 days, although they definitely do slowly return to a smaller size.

I read on one website where supposedly testicle enlargement could be permanent. I don’t see any reason to disbelieve this. I mean, done moderately and gently every 2 to 3 days, I don’t see why the testicles wouldn’t react and grow more testicular tissue.

I know that on some of the ball pumping sites, the guys who pump up huge and build up alot of fluid have REALLY HUGE nuts when the fluid leaves their sac. I’ve seen a picture of PEKKA where his sac has shrunk down completely, but he’s got two balls that are at least the size of GRADE A LARGE EGGS!!!

I just don’t want to do it if it’s going to affect fertility. But, I must say that I don’t see how a little expansion is going to make them stop working or anything. I mean, obviously the guys that are pumping themselves up really big are still VERY HORNY, so we know that at least they are still producing quite a bit of testosterone. I see no reason to believe that they wouldn’t be producing sperm as well.

I’m still open to other thoughts and experiences.

Thanks for the replies thus far.



Thanks for the input. I’m glad to know that you were able to ballpump and still be a stud!

Since you are a little more experienced than the rest of us, I was wondering what your take was on permanent enlargement. Have you experienced any long term or residual enlargement of the nuts?

Also, had you ever experienced any slight soreness or dull ache in your nuts due to ball pumping?

Do the nuts get more used to it after awhile?

Thanks again.


I’ll give it a try if I can find a container of the proper size. My nuts won’t fit in my 1 7/8” tube, so I’m guessing something about 2.25” may be what I need. What diameter do you use?


Actually I’ve used both my 1.75” cylinder and a 2 3/4 cylinder to pump just my balls. The 1.75 is a bit of a snug fit, but you get more downward pull that way. The larger cylinder stretches your sac more in all directions.

Right now, I prefer pumping my balls in the 2 3/4 cylinder because I’m looking for an overall stretch of my entire scrotum. I’m trying to get my scrotum back. Due to years of wearing briefs, I’ve gotten to the point where I have very little sac at all. I’m trying to get that back, and it’s working very slowly.


Ball pumping question

For you experienced ball pumpers, I have a question. What range of vacuum pressures are you working with? It appears that you do longer sessions for balls than for straight dick pumping (30-60 minutes vs 5-10 minutes per set for penis). Any guidance would be appreciated. Thanks!



I won’t be content until I’ve earned the name!



I use anywhere from 2 to 5 pounds. Actually, right now I’m trying to stay away from 5 pounds and work in the 3-4 pound range. If you go above 5 lbs, you’re gonna be hurtin.

If you go above 5 lbs, do it just for a few seconds to get an additional stretch, and then go back down to a lower pressure. Even at that you’re going to be stretching things quite a bit.

Personally, I think slow and steady at 3 lbs, maybe 4 is just as good if not better. Slow and gentle… no need to rip anything apart here.



<”no need to rip anything apart here.”> :chuckle:

Thanks for your response! I think I want to give this a go. My sack hangs well, but I want to increase the size of my balls. I don’t have the right size (or kind?) of tube for this, but I am going to try to work something out.

In response to some quesitons:

I never pumped frequently enough to feel I gave permanent enlargement a chance. I would just do it once a week or so as a change in pace and to enjoy the huge balls as a novelty. My balls hang pretty tight most of the time, but if I am out of a warm shower they look awesome and hang low and pretty big. I wish they were like that all the time.

I would get some dull aching the next day after ball pumping. Not too severe, but kinda like you got blue balls and you want to shoot a load real bad. (like I feel right now)

The pain I felt never bothered me too much, but yes, you get used to the “full” feeling in your nuts while they are swollen and the tenderness the following day. I found if you use really hot water and only pump for an hour or so, that the nuts themselves get bigger and the sack does not collect too much fluid. If you use no water and pump for longer it seemed to load the sack up with more fluid. I did it both ways depending on my mood.
