Testosterone!
Your testes descend from abdominal cavity to the scrotum. There is difference of one degree Celsius from body. It is lower in the scrotum. This one degree Celsius lower temperature is necessary for production of the sperms.
The sacs located outside the body and in which the testes are suspended are called the scrotum. The scrotum is a pouch-like structure that contains the testicles and helps regulate their temperature for proper sperm production and development.
'Le scrotum' or 'les bourses' are the French names for the scrotum.

Mature sperm is stored in the scrotum before discharge.
Dihydrotestosterone (commonly abbreviated as DHT) is the hormone that promotes the development and growth of the prostate gland, as well the external genitalia (penis and scrotum) in men.

The female ovaries are generally developed about 100 days after fertilization. The male testis do not descend into the scrotum until the ninth month of development although this sometimes occurs after birth.
Infants have their testicles in their scrotum from before birth, if they are not there at birth, then the doctor will have to do a procedure to get them to descend from the abdomen.
Males have glands called TESTES, which are located in the scrotum. Testes produce the hormone testosterone. Testosterone regulates male sexual development and reproduction.
Cryptorchidism is when one or both of the testicles fails to descend into the scrotum. It is also called undescended testicle(s). Uncorrected cryptorchidism can increase the risk of male infertility and testicular cancer.
The testes don't actually drop at all, therefore there will be no pain or discomfort. When a boy is born his testicles descend into the scrotum. At Puberty his testes begin to grow bigger and hang lower from the body. This is in readiness for sperm to begin being released. The sperm must be kept at an ideal temperature to be healthy and to do this the scrotum will descend and retract. 'When your balls drop' is just a figure of speech given for male Puberty beginning.
