The testicles are the organs used to produce sperm and are contained in a sac called the scrotum.
The slightly strange thing about the testicles is that in order to function (ie produce viable sperm) they need to be kept at a fairly constant temperature that is BELOW normal body temperature.
The muscular contractions and relaxations of the scrotum function to move the testicles nearer or further from your body so that they are kept at a reasonably constant temperature. When the scrotum contracts the testicles are pulled nearer to you and are warmed up - which is why you will note that they are "harder" when you (or they!) are cold.
An ancient method of contraception (not to be reccomended) was for the guy to sit over a bucket of boiling hot water so that the heat killed the sperm. A more recent phenomenon is that guys who wear tight-fitting underwear that pulls their testicles close to their bodies have been found to have lower sperm counts because their body heat is killing the sperm. If you want a high sperm count then wear boxer shorts and loose-fitting trousers!
Other factors may also induce this contraction - notably fear or a sudden burst of adrenaline. This is a normal response of pulling your vital sexual organs as close to your body as possible for maximum protection from injury (you also wouldn't want all that wobbling about if you had to run to escape from some danger).
Some people, notably martial arts guys are supposed to be able to control the contractions of their scrotum - to the extent of retracting the whole package partly back into their bodies for protection. A very good friend of mine who was a Kung Fu instructor described this to me although I have never seen it demonstrated.

I like all the answers so far - very informative and I cannot wait till I can get to level 2 so I can vote.
I like the answers; however, I cannot attest to the truth behind the theory.
I can tell you though, that mine were really tight (from what I remember as I am now around 48 years old ...) when I was around 11 years old. I mean tight - budd. I thought I was pretty bad to the bone back then.
When one day, I was going along; and ALL OF A SUDDEN, my foot slipped off the peddle ... and ever since that day my nads have been really soft and fluffy ... kind of like mashed potatos, or cotton candy with a bit of humidity.
I must admit though ... I lost my bad to the bone attitude right away, on that day. My hobbies changed a bit from sparring with the boys to feeling great about hitting those certain notes that no other guy seems to be able to hit in the choir.

They contract tightly when you get close to ejaculation; if that is what you mean by hardening--the ball sac is pulled up tightly as you should well know. I have noticed that as I get older, mine tend to hang looser than when I was young. Then, they seemed to stay in a semi-tight position most of the time, perhaps this is because that age is when we think most about sex and our balls are always ready and willing to go. I remember at the Y in my early 20's that it seemed that the older guys really had low hangers, while the younger guys were certainly more taunt. Everyone at the Y in the lockerroom was always nude, so there wasn't any modesty.

Sperm are kept healthy and produced under a specific temperature that is lower than normal body temperature. Hardening and loosening will help regulate temperature so that you will have plentiful and healthy little soldiers!

It is a matter of temperature control and ejaculation. Sperm is produced at a optimum temperature. Too cool and the scrotum tightens to bring the testes's closer to the body for warmth too warm and the testes's loosen to allow for cooling. Also at the time of ejaculation they tighten.

Sperm is very sensitive to temperature... So your nuts will harden to get warmer and loosen to cool down... All done to protect your little solders!!

Answer 1. When the concrete is cured.
Answer 2. When you degenerate into dust hopefully soon.

When you are too warm they will get really loose and when you are cold they will tighten!

its the temperature that affects the contraction man!
