View Full Version : Testicle shrinkage?

10-05-2001, 03:43 PM
I'm a healthy and sexual 30 year old. I have normal sized balls, but often, and for no reason I can tell (like cold) they shrink up to a small size. This is especially true during sex/masturbation.

Sometimes one even slides up a bit, they get so tight. They do not hurt, and it has never caused me problems. And many times they stay normal, and get just slightly tighter when I'm hard. I shoot a normal load.

I was just wondering if any other guys had this. I've noticed in some porns that some guys seem to have shrinking/tight balls, but don't know how common it is.

Well, the colder it gets, the more the scrotum shrinks and the closer the testicles get to the body. This is true with everyone. The actual size of the testicles does not change inside the scrotum. They just look smaller because the skin of the scrotum gets thicker as it contracts toward the body. This is completely normal. This happens because the testicles need to be at a certain temperature to make sperm properly. They are VERY sensitive to temperature, and the job of the scrotum is to make sure they are always at the right temperature for maximum sperm production, which is about 3-5 degrees cooler than body temperature. So, when its hot out, the scrotum relaxes and keeps the testicles as far away from the body as possible for maximum cooling. When its cold out, the scrotum contracts and brings the testicles as close to the body for warmth. It's all automatic - your brain controls it subconsciously.

Thanks for the reply, Focus. I mean that my balls get tight and recede without any cold, they just do. And during sex, sometimes, they almost seem to recede, the sack gets very small, and they are up against my penis.

It's not a bother, more just wondering if this is normal. I have no problems with erections, ejaculation, but I do wonder about if others have this.

I've also noticed that at times (not related to cold) that mine will "pull in" also. I think that I've noticed it when stressed or nervous also. As for during sex, they will pull up and in just prior to ejaculation, yours just might be getting ready early!

It is normal for the scrotum to tighten and the testicles to be pulled up close to the body just before and during orgasm. Actually, that is the first visible sign a guy is ready to ejaculate: his scrotum will tighten and the testicles move up a few seconds before ejaculation and orgasm. I'm not sure what the reason is for this, but all guys get this effect.

Just want to clarify,

I was masturbating last night, and my ball sac becomes almost non-existant for the duration, almost a few minutes into masturbating. My testicles stay the same size, but my sac gets very tight, and my balls are pretty much almost flush with my penis, on either side of it. It isn't only at the climax, but from the very start that they get this way. It doesn't hurt or affect me, but sometimes I'll stop, and push them back down. A half a minute later, they work there way back up again.

Anyone else have this?

How cold is the room you are masturbating in? If its even a little bit cool, then my testicles do the same thing, and the scrotum always pulls up very tight just before orgasm.

I think what you are experiencing is more of a temperature thing. Remember once you're naked, the testicles immediately get cooler than when they are inside underwear.

It's really not a temperature thing; they get that way in the summer, in a hot shower, etc. Sometimes, my sac just gets very small, and rather than hanging down much, the sac as it gets tighter, draws them closer to my penis, so that one is a little under and to the left, and the other is a little under and to the right. And they stay that way for awhile, from beginning to half an hour later.

Like I said, it doesn't hurt, but I had one girlfriend who was surprised at them, saying that other guys she had been with, there's still hung down; they got tight before coming, but their sac didn't get nearly as tight as mine, or their balls so up against their dicks.

No big deal; I guess it may just be the way my body is, since they get this way long before climax, and regardless of the climate.

OK - now I understand. Never heard of that before, but I don't think its a problem. As long as the testicles don't go all the way up into your abdomen.

just to let you know your body does things for a reason.if your ever in a fight your balls shrink up so they don't get damaged.Its weird but true your body has a mind of its own your body and minds' goal is to reproduce when your older.
