You probably have a vague idea of what sperm does, but not all sperm are created equal, and some have even developed unique adaptations to get where they're going.

So much time has been spent by people with microscopes, looking at sperm. People did this research, for the knowledge of mankind.

too much interpretational words. where the hell are microscopic photos? sperm must be specific to female genital tract. i can say it even without looking.

I can't help thinking that making things that don't work is more costly. Making less, but working, sperm would require a lot less input, would it not?

Why cant the "suitor" who makes the lady "arrive" be the winner... instead of this more self fulfilling agenda... or better yet one who arrives first carries the brood hahaha! Lots of seahorse models would be the norm 🤣

Nr 9 - so could, in theory, the social progress of humankind, including the abolishment of enforced monogamy and the acceptance of alternative relationship models such as polyamory, if it continues on long enough, lead to humans to develop less deformed sperm and more sperm of better quality?

NOT a very good video because you didn't even show pics of the weird sperm like the corkscrew shaped ones and did show pics of the sperm we are already familiar with like human sperm!

That moment you realize the Amish have more limited mating AND socializing habits than an animal called a "naked mole rat," in some ways it makes sense, and in other ways it doesn't make much sense.

I was so hoping you're going to use the scientific names when talking about the sperm like it's not called a tail it's called a flagella

Not surprised human sperm is regularly deformed. Monogamy was actually not the original way humans mated. Plus it's probably for the best considering how much probably ends up in a dude's socks lol Also is it wierd I'm sad they didn't mention snakes? They also retain sperm (some species) and can lay fertilized clutches a year or two later when they have not been with a Male.

Creating fruit flies So you take the fly, ok? Yeah... Now make it eat fruit. Finally a species that isn't buzzing around the hou- Make its sperm larger than its entire body. I'm sorry, WHAT!? I mean there's gotta be SOME incentive to see it.

I love SciShow and this video was good but it would have been cool to see some pictures of these 5-cm-long or "killer" sperm from a microscope. Is that too edgy for THvid? (actually, "edge" is a bad term to use in this context...)

89. That's the number of times Stefan said "sperm". He also said a word with sperm in it (um eww) 5 times. Not once did he smirk or giggle. I wonder how many takes they had to do?

A different one of anyone's father's sperm might've fertilized an egg as opposed to the actual sperm, leading to a different individual. In an alternate universe.. Maybe
