Testis Meaning and Definition in Wikipedia
Testicles are parts that are found on the bodies of male creatures. Male mammals, including men, have two testicles, supported in a sac of skin below the penis called the scrotum. Along with the penis, testicles are called reproductory organs or "sex organs". Only males have testicles; females have ovaries.
Testicles are a type of organ called glands. Like other glands, testicles make chemical substances, called hormones that keep the body working. Testicles also make sperm which can join with ova to make new life. (Read more about this in "What do testicles do?")
Most glands, like women's ovaries, are inside the body, but testicles are outside the main part of the body. This is because the testicles work better if they are cooler than the inside of the body. In cold weather, testicles pull up nearer to the body to keep warm.[See more about Testis at Dictionary 3.0 Encyclopedia]

- Big Testicles Drive Genetic Evolution: Size Does Matter After All
Large testicles drive genetic evolution, with animals with larger testis having an increased speed of genome evolution, researchers have found.
