I like how this was posted in November, of all times.
nice pic
I don't know what is important about November but, I do know that I tend to dislike the topics covered by this host.
Not much else that's interesting in November, I guess (at least here in the northern hemisphere).

Older sperm are less effective at fertilization because they keep swimming back to try to remember where they were going & why. I'm old so I understand!

That’s good to know. There’re some men who think only women have to worry about biological clocks.
This video gave zero statistics about male fertility as it relates to age. Yeah sperm quality can degrade with age. A middle-schooler could guess that much but what are the rates of infertility as a man ages? What factors contribute to faster degradation? How does male infertility at various ages compare to female infertility at those ages? This video is low information clickbait trash.

It would be more complete as a video if you also included the viability of sperm storage as in sperm banks
Why? The issue was the effects of aging on sperm, not the way that healthy sperm decay as they age in storage. Totally different subject.
@@matbroomfield the question that prompted the video was "Are Sperm Viable Forever?" Clearly that also implies sperm banks
@Mat Broomfield ... also relevant is the reason why someone would watch a video on the the topic right? Mat, If you fail to see the relevance then I don't know what to tell you.
@@derekwheeler4299 I didn't see that - I was listening podcast-style. But you're correct - yes it does, in which case the video answered entirely the wrong question in the first place, implying the age of the producer, not cryogenically stored sperm.
Sperm banks freeze their stocks. They'll be viable -- i.e. the DNA -- for as long as they can keep them frozen.

canaldecasta: That reminds me of the sperm scene in Everything You Always Wanted to Know About Sex but Were Afraid to Ask, especially the one African American sperm.
Can we take a moment to appreciate the thumbnail.
... and because the video doesn't provide any numbers, let me help - after 30-35, motility and counts can go way down quickly. So while men don't hit menopause the same as women, the timelines are surprisingly similar.

Not gonna lie I thought it was strangely apparent how he avoided the words male or men when talking about the male reproductive system..
As when veterinarians speak of spaying a female pet and castr cast cas uh neutering a male.
Men get defensive when it comes to their manhood but we as women can’t get defensive when it comes to our womanhood. They are afraid of hearing the truth about what could possibly be wrong with them but tell us women all the time. Sounds hypocritical to me.

@@j03man44 The answer to all of this is probably "we don't know yet"

I will never understand why this show hasn’t gotten better camera equipment or lights literally ever. It looks like it’s filmed with a webcam and an assortment of household lamps, rather than equipment befitting a 5+ million subscriber channel...
so if males make sperm and female ovum, what does the other spectra make?
Literally does not answer the original question at all.
Yes I was thinking more in terms of the sperm delivery system. 🤠
@@stephenpowstinger733 Well the original questions was "Are sperm viable forever?", not "What are the effects of aging on sperm?"
The video didn't just gloss over the question, it completely ignored it.
SCIENCE!!! #jazzhands
Agreed! I thought they’d also talk about trouble performing that increases with age. That paired with sperm deficiencies could have at least given us a biological clock age range
Yea sometimes they shorten the videos by not adding a conclusion. You are still aloud to come to a conclusion on your own based on the data provided. Isn't knowlage fun!?!?!
I've been on a serial killer video binge and I was noticing a lot of the killers had one parent that was significantly older than the other one. And now this video tells me that older parents have a slightly larger likelihood of having offspring with schizophrenia among other things.

My siblings used to call me an old egg when I was a kid. My parents had me in their 40's.
Dad was 45 but Mom was 21 so...
Last time I came this early... *oh wait*
It's getting continuously harder to watch SciShow videos on the bus
Any particular age ranges where one should worry about? Also, is there such thing as negative effects on sperm for being too young?
No mention of telomere length increase huh? Interesting you left that tidbit out.
you just said when men get older?! how old 30?40?50?60?
men in 30s and 40s are in their prime. So I would guess after 40?50?60? yea. we can only guess. sadly, scientific show but not much data in this one.

Do a video on the reason metal sparks in a microwave!
No real age range? Kind of a vague video IMO.
I was looking for a number too
Maybe lifestyle has a bigger affect than age
Also how is this new. Since eggs take a massive toll with age very fast, something had to be said about the known minute degradation of male gametes. Equality.

Anyone else read the title of this video but still giggle when he started yelling at you about sperms, despite being almost 30?
Dammit I was hoping to spend my 60's doing midnight feedings, chasing toddlers and attending elementary school "concerts"! I guess I'll just have to spend the coming boomer years walking naked around my house and sleeping 'til noon on the weekends.
Those "perks" are no consolation if you never had kids at all
Depends. Those perks sound good to me.
@Kathryn Geeslin ...
Do you have kids?
@@24emerald No. Two nieces. Lots of young friends. No offspring.
@Kathryn Geeslin ... ha, same here.
So have kids young to promote healthy life styles and then proceed to succeed as adults? We are having children older and older because of how unforgiving and insane modern day living is... so... looks like we will eventually mutate ourselves out of existence. Seems legit.
My parents had me in their late 30's early 40's and I turned out fine.
I’ve never came this early to a scishow video this quick (no pun intended) lol.
Have kids early so they are not autistic is the take home message here.
Not entirely accurate. Most of my friends with autistic kids had them relatively young.
I think the autism thing is environmental but theres a plethora of other things to worry about.
@@MtnTow I used Autism as an umbrella term for mental disabilities. Also your sample size for your conclusion is small.
@@Anskurshaikh I have 9 or 10 friends with kids and almost half have 1 autistic. Most are in 40s but not all and geographically spread out as well.

What age is old? Did I miss that part?
@Scishow I read that studies found several times higher risk of certain mental health issues in men that have children over 45. How then is it a small change??
If you start from a low number and double it several times it will still remain a low number.

There was stuff in class last week that went over this plus mental health of offspring, which I found interesting. But as worldwide population get married and stuff later and later in life, how that would impact the future ... hm..
Not much considering defects are still astronomically low even having children later at 35 the chance is 0.2% compared to 0.1% at 20 years old.
Please make one about the female biological clock, too
Before 16yo, too early, after 35yo too late. Mutations and stuffs.
Everyone knows about it already.
Honestly the best thing you can do is freeze your eggs/sperm the moment you hit puberty, it's only downhill from there.
They won't. They'd probably get banned or demonitized if they did.
@@Koozomec My mom had me in her early 40's. I turned out alright.
Did you remember to set your biological clock back an hour last week?
What do you mean by "older"? Is this a problem after 19, or after 59?
My great great grandfather was still having sex and had many children in his 90’s. I was not sure if that was possible for him to do.

The risk of faulty mutations increase the older you get. That is why cancer gets more common the older people get.
@@nattygsbord He asked what age.
Depends entirely on your genetics. Some people age faster than others. No 2 people are the same.
monster8090 sure, however science can still make claims like “on average your eyesight begins to decline around 48-50 years of age” why can’t they make a similar claim here?
@@brothergeorge418 Same thing. But my point is, they would have to map the entire genome of everyone in the world including you and see how or if you would ever have a problem. It's like predicting "When will I get cancer?" You may already have it or you may never have it.

The avoidance of the words “male,” “man,” and “men” was odd. Does SciShow consider those words unscientific now?
Either way if someone is "trans" whether one believes in that or not, their body is still MALE. But we as society call them FEMALE to help them cope with gender dysphoria (or at least thats how we used to understand it). Anyone with a typical male body makes sperm.

Sperm makers ? You mean men, genetically meaning XY. Or are we doing the whole name calling, gender switching thing ? I thought this was a science show.
A male can be sterile and therefore he's not a sperm maker. Doesn't make him less male.

Good luck affording a child at that age.
Wow today i am so proud to know that i am no more ordinary I am one of sperm creators
🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣
Just because you can doesn’t mean you should
All depends Austin B,
Depends if you have or don't have kids yet.
I thought I was an old egg, now my dad is having another kid. If just the sperm is old and decrepit does it have as much of a risk as both an older egg and sperm?
Eggs deteriorate and are never replaced, all the illnesses, all the pollution. Millions of sperm compete for the egg but maybe a thousand have a shot. Defective sperm are unlikely to win, the odds are so low you needent worry about it.
IVF will always be viable for men, so in a sense, yes, time actually doesn't have too significant an impact
Only if they freeze some young sperm. Wouldnt make much sense to waist thousands of bucks using the old faulty sperm. Plus if you look at IVF its the woman that goes through 99.9% of the process and much of it requires lots of medications, pain, and surgical procedures. Unless you are one of those old geezer rock stars with millions in the bank its gonna be pretty hard to persuade a healthy woman with access to fresh young sperm to go through all that.
@MyRedmamba ...
Women naturally value different things than men and for a good reason.
Smart and successful is the woman that catches old rich sperm.
Smart and successful is the man who catches young pretty girls.
Evolution and natural selection has been honed over millions of years to work most effectively. Our instincts bare the evidence.
@@24emerald The amount of old rich men is a drop of water in the ocean in comparison to the amount of women of child bearing age and the young healthy men available to them. No use wasting our time and energy trying to win the lottery of rich but wrinkled old balls and then putting ourselves through cycles of painful artificial treatments to fertilize our eggs with his withered old sperm. Id rather go taking my chances with a man in his 30s or 40s making a comfortable living wage. Smart girls go for the accountant, not the geezer.
@MyRedmamba ... hahahaaa
Heyyyyyy, ...All balls are shriveled ... there supposed to look that way.
Don't be rude huh..
Anyway, I think we have different definitions on what is "old." I'm still considering the 40 year old guy to be old. I'm not talking medical assistance here okay... And if he's a 45 or even 55 year old millionaire, that is a good catch.
And I'm not saying there's anything wrong with a 25 or 30 year old account and your both the same age. It's fine. And good on you if you feel it's as good as your going to get.
We need to know our limits right? I'm just saying, a 25 year old can usually attract a 45 year old millionaire. And why not?
Young couples, (I'm defining as 20's,) have their share of uncertainty.
Divorce rate among young working couples is still 50%
And when they do, after ten years of marriage, he's the one who will still have market value in his 30's, 40's and 50's.
And middle aged single moms are famously disillusioned about the "wall" and about how much fun is to be middle aged single mom. Men are quickly getting wise to it as well.
You may still not like the good reasons but, I will list a couple anyway. (Since your reply was kinda fun to read)
- Older guys are better lovers.
(Just what I heard)
- the older he is and younger you are, less likely he is to trade you up.
- more likely you are to stick with it if it's not perfect. And you'll be young enough to enjoy inheriting his estate.
(That's got to be good)
- mature men have more patience and often better dads.
Hmmm what else... oh yeah, there's more of them out there than you think. (Again, not talking about the boomers okay. those guys are nearly dead)
And ummm yeah,
I know balls aren't pretty...
I agree there're kinda funny lookin really. But hey, they are what they are. No use complaining about the way things are. Better to do the best with what you got.
That's how millionaires become millionaires.

This episode is pi long
No, it’s not
Almost.
No not at all, pi is a constant it’s infinite
@@haydenv9611 pi is not infinite. Probably you just meant to say that there's no integer numerical base that can express the number pi with a finite string of symbols. However, its infinite-repeating nature in base 10 (and pretty much any other integer base) is not a defining property of pi or any other irrational number.
Anyway, arguing over the length of the video because it's one second off of a clearly inferred approximation is just silly. Besides, even if the time tag was 3:14, strictly speaking, that number has always and always be inaccurate as a representation of pi because seconds are in sexagesimal base (base 60... well sort of). That means that a closer aproximation of pi in time would be 3:08, and even that can be challenged because minutes are also sexagesimal.
Almost jizzed my pants..
The problem is the male reproductive biological clock is not the same as the female reproductive biological clock, the female reproductive biological clock ends near the middle of their life expectancy . The male reproductive biological clock cause the sperms to deteriorate after the man had become sexual matured and will continued to do so thronghout the man's entire life. There is zero chance for an 80 years old lady to became pregnant but it is possible for an 80 years old man to impregnate a woman of the sexual reproductive age.
Yeah that right if man doesn't age then He's cell will replicate eternally, for females beyond age 50 is menopause.
Male germ cells never stop having children
And now, Im hungry
Partially true, as always. The Bias is showing.
Genetic, Particularly as related to Autism, Are a mother age thing. Not from the fathers age.
once normalizing for that, fathers age is not a factor.
When such *do* occur. like you said, rare. start rare, stay rare.
Whay *does* change with age, is telomere length. I.E. age problems are pushed back years.
And yes, Sperm count and quality goes down..
But if ever *that* down. the reason isn't just time.
What bias? The title is about males and the video is all about males.

Male biological Clock..
As in that, Men As the course of Nature become functionally sterile if not literally.

those did not include the illness you mentioned.

>new field of study
i really doubt that no one has ever thought about this before
once you have a large enough population with enough people of different ages having children it should become quite obvious quite early that there is some kind of pattern.
I think he means that even tho people have thought about aging causing a problem. Nobody cared enough to study it, until these researchers came along.
Wow
"avoid saying men or male at all cost" 😀 (I know, I know, no need to explain gender to me).
Absolutely horrific. I thought this was a science show. Scientifically men are people with XY chromosomes. Fact. You can't switch or operate your genetic code.
I saw that and became sad. A supposedly scientific channel avoiding the proper terms of sexual differentiation. Science shouldn't care about hurting feelings. If people want to feel they're giraffes it's their problem, science should just tell the facts... it's surreal...
I recommend Hank Green's quite recent video about biological sex. Basically, the claim is that biological sex is a spectrum. I will not quote it like it's an established fact but I think it may give the push to do some research on latest science view on the topic.
@@dhkukulka666 I've seen and read a bunch of stuff on the topic. I am aware of the la Chapelle syndrome too.
That doesn't mean that just because 2% or less of the population has this unique characteristics we should change language. And it's not gender they are discussing, is sperm which to my knowledge can only be made in male testicles. Even if you are part of this 2%.
How old? What percentage is the risk? Why do you provide no data? Why did you make a meaningless video?
Apparently, we need to draw our own conclusions that after the man's prime time, the risk of deformed sperm increases. At least women are told that getting pregnant after 35 is considered higher risk pregnancy due to higher risk of deformed babies that increase exponentially each following 5 years.
@David Gregory and they did the "sex is a spectrum" video the other day. Either they are running out of ideas or it's a concerted effort at driving a narrative. It's just frustrating when the people who gush over objective science will be the first ones to sell out.
You have 21 sources listed under the video. Go and dig up the info if you need it. It was "fast fact", there is only so much data you can include in a short, 3 min episode.
