How many ounces is the average urination for a human?

Depends on one’s bladder size. I peed into a (European) pint bottle once to see. I filled it exactly. Another time (when I’d been drinking lots of beer) I went about a pint and a quarter. I believe that I have a rather small bladder too.

:smack: Didn’t read the word “average” in your OP. Ignore me (and my puny bladder).

All I know is I used to astound the nurses when I was in the hospital. I used to fill the large jug they gave me with one um… useage…

Not sure how big it was though.

My name may suggest so but I’m no expert on these things… however, not long ago, I went just over a pint in one go (used a beer mug).

**green\_bladder** , I’m willing to bet you found this thread via a vanity search. Am I right? Am I? Eh? 😉

Ah, that would’ve been quite a safe bet. But you would’ve lost, my friend. I usually restrict my vanity searches to the less formal forums. I encountered this thread merely because words like ‘urination’ catch my eye 😉

I read once the average piss is around 400ml, give or take a few dribbles.

Don’t know what size the survey group was though.

Filled up a 500ml bottle and about half of another one, once, so that would be 750ml (or about 1.5 pints). It seemed like a lot. It was just because I had been drinking a lot of water that day.

Oh, it was a contest and I won. The worst part is we weren’t drunk!
