During arousal, the testicles are drawn closer to the body to regulate temperature for optimal sperm production and safeguard them during intercourse. The cremaster muscle contracts to pull the testicles up, which can make them appear as though they've 'gone away.' This is a normal physiological response and varies among individuals.
