The largest spermatozoa belong to Drosophila bifurca (my bad, I originally had put melanogaster), or the common fruit fly. They are 10,000 times as large as a human sperm cell, 20 times the size of the fly itself (about 60 mm).


How the hell does this work?! I understand that it's very small in diameter and probably coiled up but doesn't it need to be motile? Also, fruit flies? Really?
anyway, the information is graciously brought to you courtesy of my biology labs


edit: I was not on wikipedia. Also, my question has been answered thoroughly by Twisted Magnum. Thanks, man!

edit2: The flies making these large sperm have large testes that comprise nearly 11% of the dry mass of the fly

That is very interesting.

Are you sure that's true?

I got it from a very legitimate source, so I'm pretty positive.

In 1950, Cooper (quoted in Pitnick et al., 1995) reported that the spermatozoon of Drosophila melanogaster "proves to be a most impressive gamete." D.

so.. basically this is what you are saying... except the sperm is inside the fly's body but yet the body is smaller than the sperm ans the flies have millions of sperm. meaning the fly's body is 20 million time bigger than it actually is yet it is still the real size

Well apparently, they do not make millions of sperm cells. In fact that make very few, since the female can store the sperm in her body for about 2 weeks, probably reducing the need for a large amount of sperm

I don't understand why you guys are trying to compete with fruit flies for sperm cell size. It's not attractive when a guy's load is comprised of cells the size of small worms.

No, I didn't know you were joking. Not at all. I don't know what humor is.
Anyway, I will applaud the next time I see a snake shoot out of a mansnake.


Also, you must have a pretty small body

You know that cat's just going to eat the duck when it grows up.


Also, I had no idea that their testicles were so big. Pathetically for them, my testicles are the size of 100 fruit flies. Losers.
