The testes move away from the pelvic cavity.

Heat; excessive warmth., Intensity of feeling or expression; glowing ardor; passion; holy zeal; earnestness.
They hang outside to control their temperature. When cold the scrotum contracts and so brings the testes closer to the body for warmth. When hot the scrotum sags so moving the testes away from the body for cooling.
Signs of infection include leakage of pus from the blisters or excessive redness, warmth, tenderness, or swelling around the blisters.
Sperm production requires an environment that is neither too hot or too cold. The cremaster muscles are those that will raise or lower the scrotal sac. If the testes are too warm, the cremaster muscles loosen and the scrotal sac will hand lower. If the testes are too cold, the cremaster muscles will control and draw them up closer to the body for warmth. So it's all about temperature control.
This is an interesting question. Sperm do best at temperatures slightly below the temperature of the body. This is why the testes are located outside of the abdomen. The scrotal muscles tense and relax to control the distance of the testes from the body. If it is colder they will pull the testes closer to take advantage of body heat. If it gets hotter they will relax to allow the testes to get further from the warmth of the body. Hope this helps! (BTW, they also have a reflexive action that pulls the testes close to the body when something touches the inner thigh. This does nothing to maintain a constant temperature but it does help protect them from injury.)
It basically means, a happily inebriated man wearing mixed clothing welcomed you warmly.
They usually lay their eggs on the underside surface of leaves. this provides warmth, without direct exposure to the sun. Additionally - positioned on the underside - keeps them hidden from most predators.
It is normal for the testes to go up the abdomen if pushed that direction. ===ANOTHER ANSWER=== THE SCROTUM ON A GUY functions much like a thermostat. The testes have to remain in a certain temperature range to keep the sperm alive. If you are very HOT, the scrotum will relax and hang down to cool off. If you are COLD, the scrotum comes up and pushes the testes in your body to warm them up. So my first guess would be that your testicles are cold and are seeking warmth. ANOTHER reason is stress. If you are uptight, the act of lying down makes it easier for one or both testes to go up into your abdomen. Next time it happens, try relaxing all the muscles in your body, and do some breathing exercises to really relax. If that doesn't help, it's probably just a natural relaxed position for it. I wouldn't worry about it. The scrotum is just doing it's job. By the way; this is the reason why fertility doctors recommend boxer shorts for guys that are trying to have a baby. Tighty whiteies tend to hold the testes close to the body, and over time the heat diminishes the sperm. Also the same reason when guys get out of a pool or the ocean, their testes head north for warmth!
The testes hang outside in many mammals to keep them cool. Too much warmth is bad for them.
The scrotum is the structure that regulates the temperature of the testis. It contracts in the cold, drawing the testicles closer to the body increasing their warmth, and when it is warm it relaxes allowing the testicles to fall farther from the body, thus cooling them.
