But these sperm are on a mission- to fertilize the female egg and make a baby.
These are sperm. If you are a guy, over a thousand sperm are produced in the veins of your testicles.
But only ONE sperm out of a million are chosen by the egg to fertilize it.

The first obstacle is the fallopian tube, acidic around the walls
Most sperm are to weak to even make it to the egg
