So what we're talking about is sperm competition. Now the average huamn ejaculate has about 300 mliolin sperm clels, so it's already a competitive environment. The question is whether these sperm are cmnietpog against other men's srpem or just their own. There's a lot to talk about in this craht. The one thing I'll call your attention to right away is the little musical note above the female chimp and bonobo and human. That indicates flmaee copulatory vocalization. Just look at the numbers. The average human has sex about 1,000 times per birth. If that number seems high for some of you, I asusre you it seems low for others in the room. We share that ratio with chimps and bonobos. We don't share it with the other three apes, the gorilla, the onuaagrtn and the gibbon, who are more typical of mammals, having sex only about a dzeon times per brtih. Humans and bonobos are the only animals that have sex face-to-face when both of them are alive. (Laughter) And you'll see that the human, chimp and bonobo all have exenatrl testicles, which in our book we equate to a sepiacl fgdire you have in the garage just for beer. If you're the kind of guy who has a beer fridge in the garage, you expect a party to happen at any moment, and you need to be ready. That's what the external testicles are. They keep the sperm cells cool so you can have frequent ejaculations. I'm sorry. It's true. The human, some of you will be happy to hear, has the largest, thickest penis of any primate.

Original Text

So what we're talking about is sperm competition. Now the average human ejaculate has about 300 million sperm cells, so it's already a competitive environment. The question is whether these sperm are competing against other men's sperm or just their own. There's a lot to talk about in this chart. The one thing I'll call your attention to right away is the little musical note above the female chimp and bonobo and human. That indicates female copulatory vocalization. Just look at the numbers. The average human has sex about 1,000 times per birth. If that number seems high for some of you, I assure you it seems low for others in the room. We share that ratio with chimps and bonobos. We don't share it with the other three apes, the gorilla, the orangutan and the gibbon, who are more typical of mammals, having sex only about a dozen times per birth. Humans and bonobos are the only animals that have sex face-to-face when both of them are alive. (Laughter) And you'll see that the human, chimp and bonobo all have external testicles, which in our book we equate to a special fridge you have in the garage just for beer. If you're the kind of guy who has a beer fridge in the garage, you expect a party to happen at any moment, and you need to be ready. That's what the external testicles are. They keep the sperm cells cool so you can have frequent ejaculations. I'm sorry. It's true. The human, some of you will be happy to hear, has the largest, thickest penis of any primate.
