I have a friend that was going to the bathroom recently when he was
struck by a violent case of the "pee shivers".  He wants me to find
out what they are and what causes them.  This is where you come in.  Not
being able to describe what it is I need a guy to answer this one. 
Sorry ladies but this truly is a "guy thing".

Hello aeh5a2

According to Jon Cross, M.D., a neurologist at Jackson Memorial
Hospital in Miami, "the shiver is a response of the autonomic nervous
system."

Actually, no it's not strictly a "guy thing".  At risk of TMI, I'm
possessed of a very teeny bladder.  We're talking split pea sized. 
Should I be forced to hold it much past the initial "hm, I need to
pee" sensation, or get to the "oh my god, get the hell out of my way
or I'll pee on your shoe!" stage, actually getting to relieve myself
is followed almost always by the shivers.

Whether it's from sheer relief or some other cause, I've no idea. 
I've always attributed it to my bladder being grateful to be empty.

If no male comes to your rescue, I'll be glad to point you toward two
good discussions of the "pee shivers" phenomenon and it s possible
causes.

Just another * female* commenter...

Hmmm...I have not too much to add...
I have no such *shivers*..alas :(

Wow ... The questioner specifies that this truly is a 'guy thing' and what happens?

Three dames close their eyes and jump in ...

When ... They should not have even been looking in the first place!

Sorry, I don't know the answer either but I am a guy!

Pee shivers happen after going.  From what I've heard, it relates to
the fact that a hot liquid has left the body, therefore reducing
internal temperature somewhat.  Not sure of the truth of this, though.
 I've had violent shivers in a few cases.  Is your friend gay and was
there a cute guy also peeing in the vicinity?

OMG Nelson!!!!!!!!!!
 Harharhar..............

I've caught you peeping again.

Now, go to your room and wash your mouth out.

Let this serve as a warning to any other naughty ladies.

Sheep do it too.

Oooh, Bryan, did you just call for naughty ladies?  I can't resist a
summons like that!  And Missy, PinkF, and Steph are such good
peepers--uh, people--to hang out with that I'll risk a scolding from
you.

I came back and peeped at this one (after noticing it when it was new
and uncommented) because I was hoping somebody would reveal what the
phenomenon *is* and not just what causes it.  I am having a hard time
imagining exactly what it is that's shivering.
