Testicle
internal organ used in the male reproductive system / From Wikipedia, the free encyclopedia
Testicles are parts that are found on the bodies of male creatures. Male mammals, including humans, 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.

Anatomical terminology |
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.
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. [1] In cold weather, testicles pull up nearer to the body to keep warm.
