lol Jennifer, giving hand jobs to gorillas, in California that must be only one step away from servicing the football team.

But it does sort of take away the spontaneity of the whole thing, you know 1) put this sheath cobered in spermicides on to prevent pregnancy, and 2) when the girls want to get pregnant, lets make them jump thru loops and hurdles, to pick the fastest or most energetic.

I guess there'll be a sigh of relief from some of the females of the species when we can incubate babies from IVF to birth in 'artificial' Japanese wombs.

Clearly fears over overpopulation have died away, and there is little risk of the human race becoming extinct as long as one man has a harem or two.

But never mind smoking (and dioxins) or cycle riding. What are all those hormones in chickens & meat doing to the sperm count - any results out yet?

lol, nice article, thanks!

"Etoro people of Papua New Guinea, who believe that young boys must perform oral acts upon their elders and (ahem) swallow the sperm in order to become sexually mature"

Is this the same tribe that practices cannibalism??? Sheesh...

I'm thinking you could have recycled the title of the last blog entry for this one. Remember, every sperm is needed in your neighborhood.


You may not be aware, but "manual methods" are widely used in animal breeding, and most vets have considerable personal experience.

I've seen a deadly serious training video explaining how to use a plastic bag on a stallion, how it's more convenient than an artificial vagina, and the stallions don't seem to lose interest in more traditional foal-making.

(Regarding the previous blog entry... how can any discussion of fun physics omit liquid nitrogen ice cream?)

Forget about the Parental Advisory, you need a Hilarity Advisory.
I can see the necessity for the safety video for collecting samples, one pal in University was collecting a sample from a randy bull and toro missed the plastic bag. The sleeve of his labcoat, on the other hand...

Just for reference, Google makes it oh-so-easy to do conversions from x units to y.

Human sperm:
Chimp and monkey sperm:
Gorilla sperm:

Of course, these are nothing compared to Superman's sperm, according to Larry Niven: "Ejaculation of semen is entirely involuntary in the human male, and in all other forms of terrestrial life. It would be unreasonable to assume otherwise for a kryptonian. But with kryptonian muscles behind it, Kal-El's semen would emerge with the muzzle velocity of a machine gun bullet."

Does anyone else find the idea of an artificial womb a little creepy? Or is that just the Luddite in me?

By the way, thanks for the advice in the comments of Asymptotia.

"Does anyone else find the idea of an artificial womb a little creepy? Or is that just the Luddite in me?"

If it helps a couple have children who normally couldn't then it's just fine with me.
