The testicles are outside of the body because the optimal temperature for fertilization and operation is below that of standard body temperature. This is why wearing "whitey tighties" may cause sterilization (aka they hold the testicles too close to the body which is too hot).

Why is it necessary for the testes to be kept above body temperature?
The testicles are outside of the body for temperature control. The sperm develop best when the temperature is lower than the body temperature. If the testicles were kept at body temperature, the sperm would not develop correctly. The body has an ingenious temperature control mechanism, as well, for the testicles. If it is too hot for them, they descend and hang further away from the body. If it is too cold for them, they come up closer to the body!
Why do males have testicles?
Testicles are held in the scrotum which hangs them outside the body where it is cool enough for spermatozoan production. The function of the testicles is spermatozoan production.
Why does sterility results with undescended testicle?
The spermatogenesis is adversely affected in the retained testes. That means sperms are not formed in such testes. In the scrotum, you have little lower temperature. That is necessary for the formation of the sperms.
Why are the testicles on the outside of a males body?
Unless you are very young, your testicles should not go inside your body. Your testicles started out inside your body, but descended into your scrotum through the inguinal canals before you were born. Those canals should close up long before you reach puberty. If your testicles are able to go back through the canals into your body, you should go to the doctor and have it check out. Sumo Wrestlers, who are generally selected at a very young age, practice 'tucking' their Testicles into their body. When they Wrestle this is a means of protecting them from injury. Continually pushing the Testicles through the canal opening prevent it from closing during maturation of the body.
What does the boy rabbit do to get the girl rabbit pregnant?

Which region of the body have the lowest skin temperature?
testicles
Functions of the testicles?
The scrotum is a sac that holds the testes and associated structures. Its functions are to contain and protect the testes and to allow the testes to be cooler than body temperature, as the sperm production is hampered at body temperature, thus inhibiting virility.
Are the testicles located externally or internally in the body of hippos?
Internally
What gland does androgen come from?

Is it possible to get conjoined twins joined by the testicles?

What will happen if a person with undecended testes will not undergo an operation?
If the testicles remain in the body, the bodys' heat will kill the sperm. That is one reason why the testicles must be cooler than body temperature.
