In brief: Odds ratio

Sperm have to swim upstream the equivalent of a human swimming 8 miles.
Not all of them will survive. The odds are better of 1 making the journey if there are millions to start. Pre ejaculatory fluid can contain enough sperm per drop so one might make it to the egg. Thanks for trusting HealthTap!
