Only around 15 out of the 55 million sperm that embark on the treacherous journey to fertilise the egg are able to make it through the reproductive tract where cervical mucus, which is one hundred times thicker than water, forms part of one of nature's toughest selective challenges.
...With no central nervous system to make decisions about how to move and whenwhat controls sperms movement remains a scientific mystery

“Well, I gotta have a central nervous system.”
How about a dorsal root ganglion?
For some of my friends, that is all they have.
Would that count as a central nervous system?
It is centrally located.
Nice, I always wondered about that.
Sounds good, but I’m happy with the SSD.
The rotary stuff might slow my solitaire game?
All you need is a single fast one.
What do the “bad” swimmers produce? Democrats, Antifa, BLM, snowflakes, femi-nazi, Clintons, Beto’s, Lie-a-watha (however her DNA level only goes up when she sleeps with native American s), etc.
The pyramidal tracts are a housing development outside of Cairo.
Too bad.
You're the champions if you answer correctly.
The pyramidal tracts... are a complex of multi-synaptic lower motor neurons... which interconnect the basal ganglia with the reticular formation.
You said, "Lower motor neurons." The answer is: Upper motor neurons.

Same here, though it’s possible you’d be a half of two someone elses, as it took both an egg & sperm to create you. I’ve occasionally wondered who would have been created if a different sperm met my mother’s egg & a different egg met my father’s sperm, meaning the ones that created me. No way of knowing, amen, I am grateful to the ones that created me for meet & combine to make me. So mind boggling.
Just glad they can’t swim thru a latex wall ...
Sell it on Craig’s List.

“... cervical mucus, which is one hundred times thicker than water, forms part of one of nature’s toughest selective challenges.”
So rinsing away the cervical mucus before intercourse should enhance the chance of pregnancy in infertile couples.
It's ridiculous how they obviously can't say it was created. There's no way on God's green earth that these incredibly complex sperm AND the incredibly complex egg just happened to evolve so that they could work together to create a human being. No way that happens due to "evolutionary pressure".
No it has to be cervical mucus. Anything thinner and it can't go forward. Nothing there at all and it can't swim.
Even the parts took intelligence to create. There are so many good creation youtube videos about the complexity of proteins alone.
We’re all winners of the Fallopian Derby.
Were all winners of the Fallopian Derby.
Mostly so, but like the students that gained entry via the ‘side door’, some used exceptional methods to finish first.
$$$ IVF.
its possible youd be a half of two someone elses
Yet again, this makes my brain hurt.
