WHY do ur balls/sac grow and shrink

[koolanimal]

ok so wats up with my balls like getting bigger and then gettin smaller
sometimes my ball sac is really lose and just hangs low, other times it is super tight close to my body
wat the heck?

[Unkownn]

Its all to do with keeping the balls the right temperature for te sperm to survive in.

The sac hangs close to the body(shrinks) when its cold to keep warm, thenhangs low when its warm to stay cool.

Unknown took the nail and hit it on the head, the poor, helpless nail!

Yeah, anyway... It's down to temperature control since sperm requires very specific conditions to survive.

Fussy little buggers arn't they!

[OhNoes]

just goes to show you how awesome our bodys really are

I testes need to be kept roughly 1 degree Centigrade less then normal body temperature. For the body to regulate that the scrotum is designed to expand and retract in order to warm them up or to cool them down, this is why on a REALLY warm day they may sag to an extreme length then on a freezing day you could have almost no scrotum at all, figuratively speaking of course.

temperature controll man. think of it as air con for the balls

Must be the temperature that is affecting this. Don't worry it's normal.

Must be? Hehe it is!

The scrotum adjusts depending on the temperature in order to preserve the semen. Semen cannot be exposed to extreme cold or hot for long periods of time so the body works to prevent this.

i dont have sperm/semen

[lamborghinidude]

if it is could ur scrotum will git tight and if it is hot the scrotum will get loss

[blue's anatomy]

In order for your balls to produce sperm, your balls must be at a different temperature than the rest of your body. This is why when you are warm yourself or are in warm weather, your balls hang further away from your body and when you are cold and when you are in cold weather, your balls will be closer to the body to help regulate that perfect temperature.

It amazes me when it is really hot out just how much skin there actually is on the scrotum.

Temperature is true. Get in a chilly pool for a little while and see when you get out, how they are close to the body, and as you warm up, they get farther away.
