Q: Is sperm the largest constituent by volume of seminal fluid?

A: In most cases, yes.

By a substantial amount.

In your case, no.

To a puzzling degree.

Your seminal fluid mainly consists of microscopic warships from the Cat's Eye Nebula.

You should probably see a doctor.

I'm not a doctor.

I never said I was a doctor.

I just asked for your sperm sample.

You're a very trusting man.
