Apologies in advance, its a bit of a grim subject but one that needs to be addressed.
I remember hearing that there have been three famous bands named after the average amount of sperm released in a male orgasm. The first two were 10cc and That Lovin’ Spoonful but I can’t recall the third one.
Anyone know?
Can’t believe I just said that. I’m a veteran doper. 
But that should answer your question, I hope. Type 10cc into search and it should get there. It won’t let me link to the exact page.
Although 10CC may have taken its name from the quantity of the male ejaculation, evidence seems to indicate that they got the amount wrong. According to the master, its only 5CC.
It lets me link directly to it. Because I’m special.
Probably the most famous, Pearl Jam!
My bad,
"The name Pearl Jam comes from a special recipe Eddie’s grandmother used to create some rather interesting jam. If you check out the ‘thanks’ section in the Ten insert, you’ll notice that Eddie thanks ‘Great Grandma Pearl’. So, for those of you who still think that ‘pearl jam’ is actually a refence to semen – think again, and get your minds out of the gutter. It’s just a reference to a hallucinogenic recipe." - from here.
::sticks tongue out at SmackFu:: Oh yeah? I answered first, so there. 
yeah ok, that link above deals with 10cc but what about lovin spoonful but what would the third one have been?
I recall it was an older band than Pearl Jam anyway, same sort of era as the other two - 60s/70s but really, really famous, I just cant remember their name.
Ill kick myself if someone says it.
I was always under the impression that “The Lovin’ Spoonful” named themselves after the Mississippi John Hurt song.
It wouldn’t be “the Reluctant Mouthful”, would it?
(Runs for cover sniggering childishly)
Perhaps you’re thinking of Steely Dan, who named themselves after a dildo?
It appears that the number of bands that really did (as opposed to allegedly) named themselves after cum is down to zero.
I think you’d have better luck with finding bands named after phalluses (artificial or otherwise):
Steely Dan
Sex Pistols
Throbbing Gristle
Buzzcocks
Baby Gravy?
Nine Inch Nails
You’re exactly right, Spritle!

No cite I’m afraid, but I don’t believe this is a phallic reference, but a reference to the length of the nails with which Jesus Christ was crucified.
I think both Nine Inch Nails and Pearl Jam fall into that great double entendre category, sure they may have “legitimate” explanations but the sexual connotations are pretty obvious and amusing. It adds depth. I remember an interview where Courtney Love refered to her brief affair with Trent Reznor by saying the band should have been named Three Inch Nails.
I am personally rather suspicious of the Pearl Jam explanation about Grandma, I think this was made up after the fact to give them something they could say on MTV, etc. There is a long history of rock stars pulling pranks on journalists.
Thought of another ejaculatory reference!
