Because they need to be outside to create the best temperature for the production of sperm. Which is why they tend to raise up when it's cold. It's just a temperature thing.
Who ever designed the male body was having a right laugh that day.

The testicles, or testes (singular testis), are the male generative glands in animals. Male mammals have two testicles, which are often contained within an extension of the abdomen called the scrotum.
In land mammals, with the exception of the elephant the testes are located outside of the body, as they are suspended by the spermatic cord and within the scrotum. "This is due to the fact that fertile spermatogenesis in mammals is more efficient at a temperature somewhat less than the core body temperature (37°C or 98.6°F for humans). The cremasteric muscle is part of the spermatic cord. When this muscle contracts, the cord is shortened and the testicle is moved closer up toward the body, which provides slightly more warmth to maintain optimal testicular temperature. When cooling is required, the cremasteric muscle relaxes and the testicle is lowered away from the warm body and are able to cool. This phenomenon is known as the cremasteric reflex. It also occurs in response to stress (the testicles rise up toward the body in an evolutionary effort to protect them in a fight), and there are persistent reports that relaxation indicates approach of orgasm. There is a noticeable tendency to also retract during orgasm.
The above are the reasons the testicles are located outside of our body.

The optimum temperature for sperm production is 2 degrees lower than human body temperature and as such the testicles are kept cooler by being on the outside.
This is true of all mammals except the platypus and the echidna which have internal testicles and no scrotum.

In order for the testicle to function properly and produce sperm, the temperature needs to be 2 degrees less than the body temperature. That is why it is away from the rest of the body..dangling down. In case you sit in cold water..it shrinks and comes closer to the body to maintain the correct temperature. Its bodys mechanism to ensure that healthy offsprings are produced.. :)

It's a process that evolved in order to ensure adequate temperatures for sperm to stay at their optimum fertile rate.
This is why when you're cold, they'll tighten up and move close to the body. When you're hot, they'll loosen away from the body to increase air flow around the testes and thus cool them down.
If the temperature gets too cold, the sperm will die. If it's too hot, the sperm will die. They need to be at a certain temperature, and that's a round 34 to 36 degrees C. The internal body temperature is approximately 37 degrees C, so obviously being internal would be no good at all.

LOL yeah however the interior your physique can warmth up quite speedy and is extra good to maintain cool. If a male wears boxers and shall we his testicles air out they stay cooler and enhance sperm production interior you need to no longer save them cool like that lol.

You asked why they were shrunken into you the other day. Got a bit of a fixation there haven't you? They are dangling out to get cooler.

Hi Friend..
Sperms are Produced in the testes.. It need to be lower than the Body temperature 4 the sperms 2 be active. Thats the basic reason..
In short: They want 2 be COOL..
Regards..

Two reasons, kiddo:
One: Practical necessity (they require a lot of cooling to avoid cooking the poor little wigglers before they can go out into the void to find an egg); and
Two: Sexual dimorphism (it's how we tell the difference ... ever try to sex a parrot or a kitten? Even the pros can make mistakes.).
Cheers.

If they were inside they would get too hot and burn the little swimmers. You know like when you have a temparature they seem to be trying to get away from you, and when you're cold they huddle up a little more.
