Why is it necessary for the testes to be kept above body temperature?

The testicles are outside of the body for temperature control. The sperm develop best when the temperature is lower than the body temperature. If the testicles were kept at body temperature, the sperm would not develop correctly.
The body has an ingenious temperature control mechanism, as well, for the testicles. If it is too hot for them, they descend and hang further away from the body. If it is too cold for them, they come up closer to the body!

Why are the testes located outside the body in human?
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.
Should the testes be warmer than body temperature?
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.
Why is the temperature of the testes lower than core body temperature?
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.
What condition is necessary to produce viable sperm?
To produce viable spermatozoa, the testes must be maintaned at slightly lower than the body temperature.
Why do men have ballsacs?
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.
What is the temperature necessary for normal sperm production?
The best temperature of the testes for normal sperm production is 1-1/2 to 2 degrees below body temperature, so, say, about 97 degrees.
What is the significance of the location of the testes?
The testes, locatum in the scotum below the penis, are external to the body. As a result, they are cooler than the rest of the body, a necessary attribute for proper sperm production. In fact, the scrotum has muscles that allow it to contract and relax, raising and lowering the testes relative to the abdominal cavity, thereby regulating their temperature
Why do testes in mammals descend into scrotum?
The production of sperm requires a lower temperature than body temperature (in mammals) therefore it is necessary for the testies to be removed from the general mass of the body.
Does the scrotum of the male pig provides a temperature for the testes that is slightly warmer than body temperature?
No, I think it's the other way around. The testes hang out so they can be a bit cooler than the body.
Why must the testes be outside of the abdominal cavity?
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.
How do the scrotal muscles help maintain temperature homeostasis of the testes?
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.)
Is the scrotum found outside of the body?
Your testes descend from abdominal cavity to the scrotum. There is difference of one degree Celsius from body. It is lower in the scrotum. This one degree Celsius lower temperature is necessary for production of the sperms.
