Although in the human body millions of sperms swim to fertilize, and only one does the job while others die out, how many millilitres "'ON Avarage'" should be given out in order for that one sperm to reach destination? (more or less avarage in millilitres or teaspoons)

The average volume of an ejaculate in man is around a half-teaspoon which contains 40-600 million sperm.

In mL, the average is 4mL.
