well If you spit in to the vagina before penetration when you climax and ejaculate the enzymes in the saliva will denature the sperm therefor killing it and conception will not take place.
If sperm were to be put in a sperm bank the average life span of a sperm once ejaculated is 4 days however in some cases sperm has survived 6 days and was still able to fertilize an egg.
Sperm whales can live to forty years or more.
1 hour
one day maximum
yhh
No average life span of sperm is 4 days, sperm can live in a woman's body 6 days after intercourse
1. 500 million sperm are produced and matured each day by a healthy average male 2. after a sperm has penetrated an egg the outer shell of the ovum makes it impossible for any other sperm to penetrate it. 3. the ovum is larger than sperm 4. the life span of a sperm on average is 36 hours 5. the average life span of an ovum is 12 to 24 hours
Birth control doesn't affect the sperm's life span. They can live about five days.
No, their life span varies to an hour or half hour after ejaculation. That's why at sperm banks they freeze them.
Excessive use shortens life span
An overuse of just about anything will affect the life span adversely. In the case of batteries, how severe the effect is would depend on the specific technology used.
