No muscle, but opposing sliding actions of tubules in the tail
This resource doesn't explain how energy is transferred to the sperm tail, but it does show you the structure. I suppose its accurate, since its Khan Academy. You'd have to check with a journal database to be sure. Cellular MovementVery interesting. I'm curious what causes the tubules to move.

"That may well be true sir but we're still going to have to ask you to leave the park."I also heard that sperm are attracted to violets, the uterus emits a similar smell which gives them their guidance
That i dont know but i think of it along the lines of "what causes us to keep out hearts beating?"

From my amateur genetic genealogy perspective, it's the mitochondria at the base of the tail that's the "work-horse" that powers the tail which moves the sperm. Mitochondria are little non-cellular energy-production factories. They float around in a female's egg, turning whatever it is that they convert into energy and, in a sperm, providing the energy necessary for sperm motility.
Every human, male and female, inherits his or her mitochondria from his or her mother which provides the genetic information that genetic analysts use to "source" a person's maternal ancestry.
So, if every human, male and female, inherits his or her mitochondria from his mother, but not from his or her father, what happens to the mitochondria at the base of the sperm's tail?
In the process of entering the egg's nucleus, the mitochondria-powered tail (and mitochondria) drop off. The tail and its mitochondria have done their job and are no longer needed. That's why we don't inherit any of our fathers' mitochondria, only our mothers' mitochondria.

I read a perspective from Douglas Hofstadter that's been bouncing around in my brain for months now:
- When you install a new OS on your computer, the entire OS is represented as a single, stupendously long integer (in this case, a binary integer).
- When you make a new creature (humans too), that creature is represented - in DNA - as a single, stupendously long integer (in this case, in base 4).
