Sperm can stay alive under the right temperature and other conditions conditions for about 3 days without being frozen.
It is usually collected ONLY AT the sperm bank so it can be placed in a controlled temperature environment before freezing.
If a sperm has died, there is no reviving that puppy, but the vagina has a fairly constant temperature, and that makes it possible for sperm to live for a little while (usually up to 72 hours), but many will die.
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.
They are cryogenically frozen to suspend animation.
If he stays in long enough and often enough to significantly raise the temperature in his scrotum, then the sperm currently under production will be somewhat degraded. However, sperm is under constant renewal and it doesn't take ling for the sperm quality to bounce back.
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.
A sperm can survive at a temperature of between 33 to 35 degrees Celsius.
Artificial preservatives are made from frozen sperm from billy goats while natural preservatives are fresh never frozen 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.
There is no expiration date on frozen semen, as long as the semen are not constantly thawing and freezing again, the sperm can be frozen for as long as needed. Take care. This is very wrong there has only been sperm given 12 years frozen to someone and they had a fine child. Anything after this they are not sure of
In order to produce sperm the gonads need a slightly lower temperature than body temperature. This is why testicles are external body organs.Now vampires are not frozen (else how would they be able to move, ice is very solid, y'know. Ever tried to bend a frozen weaner?) but they are cold, just cold enough for sperm to be still actively produced. This is why male vampires are still able to father children. (No female vampire however has ever mothered a child.)
Yes, tanning beds can reduce sperm count. Sperm is stored in the testes in the scrotum for a reason. The sperm needs to be held in the scrotum because sperm cannot survive the regular body temperature and needs to be kept at a lower temperature (in the scrotum). When men tan, the temperature of the sperm increases, killing them.
