How electroconductive is semen?

That’s not an answer to the question, since what you measured is a property of the sample, not of the substance. Yes, you measured the separation of your electrodes, and that’s important, but it also depends on the geometry of the sample.

Measuring the conductivity of a liquid is more difficult than measuring the conductivity of a solid. For a liquid w/ mobile ions, the DC conductivity will not only be a function of geometry, but of time. (I believe this is because the mobile ions will be swept toward the probes.) Because of this, instruments that measure the conductivity of liquids usually use a low level AC excitation voltage.

In addition to geometry, the conductivity of a liquid is a function of the magnitude and frequency of the AC voltage. It’s a rather complex measurement.

Is this addressed in the cavitation-method cite? I was wondering about Vicullum’s result as well.

I’m aware conductivity depends on cross-sectional area and length (I have a degree in electrical engineering). However, we’re investigating a material whose properties vary from highly liquid to viscous to solid, depending how long you wait. Had the material been in long, thin pipette would I have gotten a different answer? Of course. But how often does one encounter semen in that state? The way I measured it–sitting in a small pool–is about as representative an example as you can get.

If you people want a more thorough answer then run your own experiments.

We tried but have had a hard time finding a cooperative lab assistant.

Well there’s your problem. Get out of the pool, which is compromising your sample, and measure it on a proper lab bench.

You’re lucky you didn’t electrocute yourself.

That could be a very useful information for all sex robot makers.

Also for all electric fence fetishists.

But the question isn’t “what is the resistance of a typical puddle of semen”, but “what is the resistivity of semen”. The latter question will have the same answer no matter how the sample is arranged. What you did was equivalent to determining the density of semen using the formula “density = mass divided by length cubed”, which, if your sample is anything other than a cube in shape, will be wrong.
