Long enough for the police to get a DNA sample!!!
Seminal fluid dries out very quickly when it's outside the body - and once it's dried, the sperm die almost at once.
How quickly it dries depends a lot on what the surface is.
On a human hand, the drying/survival time would be very short.
Are we talking about human sperm, i have had bad experiences with the animal kind.
no, sperm cant last long outside the human body and if its dry then there's no way it is alive.
Up to 72 hours.
Y sperm can stay in womb for 36 hours after which it dies
How long sperm can survive in the female body depends on how healthy the sperm are and whether the female is fertile at the time. If there is fertile quality cervical mucus present then sperm can potential survive for up to a week within her body.
It can take 12 - 72 hours for human sperm to reach the egg.
A day
A sperm cell is only a fraction of a millimeter long. Typically a human sperm is about 5 microns long. A micron is equal to one one-thousandth of a millimeter.
No. Sperm cannot survive outside the body for long
It depends on what birth control method you're referring to. If using hormonal birth control this stops fertile cervical mucus being produced, thus the sperm will not survive for long within the acidic environment of the vagina - a few hours to a few days at most. Obviously if you were using spermicide the sperm wouldn't survive more than around 30 minutes to an hour.
A sperm can survive at a temperature of between 33 to 35 degrees Celsius.
The average sperm cell survives for about three days (72 hours), however in some cases sperm cells have been know to survive as long as 6 days. That's why we use condoms!!!
