Scrotum facts for kids
The scrotum is the bag that holds the testicles in male mammals. It is made of skin and muscle and is found between the penis and anus.
The function of the scrotum is to keep the testicles less warm than the rest of the body. Human testicles work best at 36.8 degrees Celsius (98 degrees Fahrenheit) when normal body temperature is 37 degrees Celsius (98.6 degrees Fahrenheit). Higher temperatures than 36.8 degrees will damage the sperm inside the testicles.
