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.
Is it true that perm can develop normally only in sightly cooler temperature than normal body temperature?
Yes, it is true that sperm can develop normally only in sightly cooler temperature than normal body temperature. Sperm need a cooler temp than the rest of the body. The scrotum keeps sperm lower than the body, but tight shorts can keep the testicles too warm for the sperm.
Do hot tubs reduce sperm cells?
The sperm need to be cooler than body temperature, hot tubs increase the temperature of the testicles above body temperature and production of sperm is decreased.
IS sperm best produced at body temperature?
No, it is not. That's why the testicles are not internal organs; this is where semen is produced. To be able to produce it, the testis need to be a bit cooler than regular body temperature.
Do Porcupines need to be at a certain body temperature?
A dolphin (species indeterminate) maintains a core temperature between 35C and 36.9C when healthy. The outer body temperature is naturally cooler.
What happens when the testes become warm?
Production of sperm is reduced. The testicles need to be cooler than core body temperature for the production of numerous and viable sperm.
Why testis of a man is outsider in his body?
To produce sperm properly they need to be a little cooler than body temp. Being outside lets them hang or pull up tighter to adjust the temperature.
Can amphibians regulate their own body temperature?
No, they cannot. Amphibians are cold-blooded and thus have no biological body temperature regulation. Their body temperature is dictated by their environment. They can regulate their body temperature to some degree by choosing their surroundings. For example, they can be warmer by being in the sun or cooler by being in the shade, etc.
The optimal temperature for sperm production is about normal body temperature?
Temperature below body temperature in neccessary for sperm production. That is why the testicles are descended; they need to have a separate, lower temperature system.
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.
What happens to air particles as they cool?
The cooler the temperature, the slower the particles move and the closer together they are because they don't need as much room. That accounts for how cooler air is thicker.
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.
