The life span of sperm after ejaculation depends on the circumstances. Ejaculated sperm remain viable for several days within a woman's reproductive tract or in nutritive liquid (culture medium) in a lab setting.

If a sperm is at body temperature (38 degC) itâll swim around a lot, and the battery wonât last very long â perhaps 2-3 hours maximum. At room temperature (22 degC) a sperm will swim a bit, but not a huge amount, and its battery may last up to 8 hours.So thereâs no simple answer to how long a sperm will live after ejaculation.nswer They say that sperm can survive for up to 5 days, although this is only in the right 'conditions' eg. fertile cervical mucus. Usually they would last for 2-3 days and that would be just prior to ovulation when your cervical mucus resembles egg whites.
