The sperm keeps it temperature because the ball sack will lower when the body temperature is to warm for the sperm. Although if the air is to cold the ball sack
will higher closer to the body and warm up the cold sperms.
The testicles are found in the scrotum. Together these are outside the body and the sperm production area remains cooler than normal body temperature. Once the sperm are ejaculated and move up into the vagina and into the Fallopian tubes, they are not affected by the higher temperature. The time this takes is too short to have any effect.
The sperm is held in a compartment, the scrotum, that raises or lowers to keep the testicles and sperm at a constant temperature lower than body temperature.
Sperm are produced in the testicles and, since they are outside the abdominal cavity, they can regulate their temperature independently of the rest of the body.
the scrotum
Sperm cell nutures the sperm and helps protect the spermatozoa.
Most male mammals have testes in an external sac in order to protect their sperm from overheating. Excessive heat can impair sperm, negatively affecting fertility.
Serum is the fluid that protects the sperm cells.......................................................... >_
Slows the loss of heat from the body's core
Because they they can survive heat and their body parts help them to protect against heat.
Sperm develops best when at normal body temperature. They are very sensitive to temperature changes. Thus, the body does everything it can to help regulate the internal temperature to help protect the reproductive area.
Not sterile but it can surely reduce the viability of your sperm. The testicular sac is situated outside the body for just this purpose. The heat weakens the sperm mobility.
Fur is what covers the wolf's body to protect it from cold and heat
Shoes do not conduct heat therefore they protect feet from heat.
As new sperm are made in the body, there is no shortage of them in the body.
Not without killing the sperm too.
The scrotum needs to be able to move away from the body and closer to it depending on the need for heat. If your body is to hot the sack will expand and move away from your body and if it becomes to cold it will tighten and move into your body. This is all done with sperm production in mind as if its too hot or cold the sperm will die.
