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.
Sperm cells die at high temperature, or for that matter, even at body temperature. Hence the testes are placed in an extra abdominal sac -scrotum where temperature is 2o below the body temperature!
Your testes have to be about 38 degrees celsius, or your sperm dies. That's why your testicles expand and contract, to keep warm, or cool down. Cold water makes them shrink so as to conserve heat .
A temperature a couple of degrees below the normal body temperature of 98.6 degrees F is needed for sperm production. That is the reason the testicles are outside the male's body in the scrotum.
Sperm must be kept at an optimal temperature for sperm to form correctly. This is why the testicles are housed in the scrotum. The scrotum has the ability to relax or contract to maintain a constant temperature.
The relationship between temperature and sperm production is that sperm require a cool environment in which to live. For that reason, the testes are outside the body of a man.
Sperm is produced in your testes, balls, and need to be kept very warm.
yes. it so effects sperm production. as they are heat sensitive, when there is a increase in body temperature the sperm count in men decreases.
the
Temperature
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.
37 degree below
Testicle temperature regulation is essential in maximum sperm production.
Lower than body temperature
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.
Production of sperm is reduced. The testicles need to be cooler than core body temperature for the production of numerous and viable sperm.
The mid piece of sperm contains mitochondria, which is required for energy production. The energy is used to propel the flagellum(tail).
The scrotum of a male, is outside the body, because sperm production requires a cooler environment then the internal body. So, the external location actually is required for production of the sperm.
cremaster
The best temperature to keep sperm alive is with the human body. You may realise that during very cold temperatures your scrotum tends to go closer to your body. This is because they want to get the body heat. Once the sperm leaves the penis, it will not survive for very long.
The best temperatures that sperm are produced is 37oc. if the temperature is higher than this then the scrotum lowers and if its colder than this the scrotum contracts and becomes more wrinkly.
