According to this site (sperm facts), I listed some of the interesting one.

Average volume of semen per ejaculation: 1-2 teaspoons
(I know mine is in 1-2 tablespoon. No wonder my balls so big.)

Average number of times a man will ejaculate in his lifetime: 7,200
(I'm coming close to this....I'm not even in my forties yet.)

Average total amount of lifetime ejaculate: 18 quarts
(1 quarts = 0.95 litres and is 17.10 litres of lifetime? Oh, I can fill up about 13.5 bottles of 1.25litres of coke bottle)

Average speed of ejaculation: 28 miles per hour
(I can't calculate my speed but I can shoot even through the wall when I was young. But ever since reaching my thirties, my speed is nil. My ejaculation is basically drip...drip...drip.)

For one, a healthy human male produces about 30 million sperm each day. With one ejaculation, 300 to 500 million sperm are released. Men continually produce sperm, day in and day out, throughout their lives.
(For those who think themselves as useless, think again. Even before you're born, out of the 300 to 500 million sperms, you are the fastest.....a winner.).
