Wikipedia Meaning and Definition on 'Scrotum'
In some male mammals the scrotum (also referred to as the cod or scrot) is a dual-chambered protuberance of skin and muscle containing the testicles and divided by a septum. It is an extension of the abdomen, and is located between the penis and anus. In humans and some other mammals, the base of the scrotum becomes covered with curly pubic hairs at puberty. The scrotum is homologous to the labia majora in females.
The function of the scrotum appears to be to keep the testes at a temperature slightly lower than that of the rest of the body. For human beings, the temperature should be one or two degrees Celsius below body temperature (around 37 degrees Celsius or 99 degrees Fahrenheit); higher temperatures may be damaging to sperm count. The temperature is controlled by the scrotum moving the testicles closer to the abdomen when the ambient temperature is cold, and further away when it is hot. Moving the testes away from the abdomen and increasing the exposed surface area allow a faster dispersion of excess heat. This is done by means of contraction and relaxation of the cremaster muscle in the abdomen and the dartos fascia (muscular tissue under the skin) in the scrotum.[See more about Scrotum at Dictionary 3.0 Encyclopedia]
