Depends: It's not the oxygen that kills sperm it's more the ambient temperature. Also sperm does not survive well within the semen. So to answer your question the temperature matters and also the environment that the sperm is in will determine the length it survives.

Depends where: Sperm can live up to a week in the fallopian tube if they get that far. Do not survive more than a few hours in vagina unless they pass thru opening in cervix. They need to pass thru uterus to fallopian tube to survive. Die soon after ejaculation if outside vagina. Can survive many years if frozen as at a sperm bank. Need to be inserted rapidly after ejaculation if used for artificial insemination.

Minutes: Sperm is very sensitive to any environment other than testicles. Even in the vagina tons of sperm cells die quickly. Outside of the body it dies quickly as it dries up.

NO: This may be a misconception for couples using the "pull out method" for contraception. Sperm may not be viable for long "out in the air" however, if you are using the pull out method for contraception, normal sperm are very active and strong swimmers, so even if most of ejaculation happens after "pull out" and , even small amounts left close to the vagina, can make a bee line to the womb.
