If the testes are not maintained at a temperature about 2 °C lower than body temperature the process of spermatogenesis will not take place, so that is why it is important for the testes to descend into the scrotum during maturation.
No. The testes should be cooler than the body, that is why they are on the outside and not inside the torso.
The testes are slightly cooler.
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.
a healthy body temp is 98.6 degrees Fahrenheit
Normal human body temperature is 37 C. Fevers should be diagnosed by physicians.
There are a lot of nerve endings in your feet and hands so they are very likely to get cold. When, you warm them then your whole body will be warmer because they were the coldest part of your body.
warmer temperatures will cause the milk to sour faster because the enzymes that cause the protein breakdown into amino acids (hence the sourness) have an optimum temperature at which they work and this is usually just above body temperature. That is why milk is stored in the fridge.
No, I think it's the other way around. The testes hang out so they can be a bit cooler than the body.
The testes are located outside of the body because the bodies temperature is too high for the testes and the scrotum has a lower temperature for them to be able to produce sperm.

The testes need to be kept at a temperature that is just shy of body temperature. The normal textbook body temperature is 98.6, the testes need to be kept at about 96.2 degrees Fahrenheit.

The temperature of wooden or metal spoons depends on the temperature of the environment.
The temperature needed for the sperms to survive and thrive is lower than the optimum body temperature , hence it is not possible to maintain a lower temperature inside the body hence the testes are located outside the body.
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.)
Because sperm function at 35 degrees where as your normal body temp is 36 so the scrotum is meant to keep the sperm slightly cooler then the rest of the body. That is also why when a male becomes cold the scrotum becomes smaller to bring the testes closer to the body to keep them warmer thus keeping the sperm warmer.
The sperm count is dependent on the temperature of the testes. The testes are external to the body because they require a lower temperature to produce viable sperm. The testes work best at temperatures slightly less than core body temperature. Spermatogenesis is less efficient at lower and higher temperatures. This is the reason for retraction of the testes in the cold as well as non-viable sperm in men with (medically) undescended testes.
The scrotum will hang lower which moves them away from the body so they cool off. When the testes are cold, they will draw closer to the body. This is a built in temperature control system
It isn't that hot. A cow's body temperature (which is around 101 to 103oF is only a few degrees warmer than our normal body temperature (which is around 99oF). But the probable reason that a cow's body temperature is warmer than a human's is because of the built-in fermentation vat that cows have which humans don't. Fermentation process quite often creates heat, which will make a ruminant's body temperature a little warmer than a non-ruminant's body temperature.
