it's Not a problem. It is a Blessing. And, the other continents will have the same issues, they just arent testing as thoroughly for it.

>>12761206
It's not seen in those countries because people there still eat decent foods and don't have their water supplies polluted with hormones and micro-plastics. It'll happen everywhere sooner or later, and the only way to solve it is figuring out which chemicals and pollutants are causing it

>>12761215
exactly. the article points out endocrine-affecting pollutants, which are in just about every plastic product and pesticide/ herbicide used in the entire world. not a western issue by any means

>>12761215
>study already says it's specifically a western problem
>"i-if i wish hard enough the data will be wrong! and if it isn't then it's a good thing anyway!"
cope
they did test for this and found it wasn't anything even close to the western decline in sperm
they controlled for lifestyle and obesity and literally the only thing that correlated with the decline was living in the west

>>12761215
100% guaranteed this poster is white
>>12761218
Phthalates, for one. Evidence for them getting boys to become more like girls both physically and psychologically is overwhelming.

>>12761206
so this is why governments are pushing so heavily for open borders. they "accidentally" mass-sterilized us and want to prevent the inevitable extinction collapse of western populations.

Is this a sample bias issue and the actual numbers are better?
If not, is this caused by some kind of population-wide genetic thing?
If not, is this caused by plastics, chemicals leaching from plastics, chemical pollution in the diet, chemical pollution in the drinking water or chemical pollution in the air?

>>12761443
no
it's far too rapid to be genetic, it's almost completely impossible for this to be true
it's phthalates for one, as >>12761281 said
they're strongly associated with reduced sex drive, reduced penis size, change in male behaviour to become more feminine (even as children, studies have shown this very clearly), space between anus and penis becoming smaller (like in females), and more importantly these effects accumulate across generations since the child is exposed to these effects in utero and the germ cells will be affected before birth
nobody will address this because it provides strong evidence transsexualism is caused by chemicals

>>12761206

Kek

>>12761458
>these effects accumulate across generations since the child is exposed to these effects in utero and the germ cells will be affected before birth
PS this is why it's whites being hit hardest despite Asians having objectively worse pollution currently as the effects have been stacking ever since we invented these chemicals

>>12761458
Tell me about this anon. What foods are the worst with this kind of stuff? Just plastics? I have been almost exclusively drinking from plastic bottles since I was a kid because of shit in tap. What the fuck am I supposed to do?

>>12761479
nothing, even tap water is full to the brim with microscopic plastics. there is literally nothing you can do, because it is an environmental pollution issue.

>>12761485
So you're saying the only solution is the final solution?

>>12761488
the solution is to ban plastics the same way we banned lead, mercury, asbestos, etc.

>>12761494
You think it will happen?

>>12761479
You can fix this mostly. Of course >>12761485
>even tap water is full to the brim with microscopic plastics
is true, but you can do many things to help.
But it is basically what you got told by doctors and parents. You need to eat healthy. Eliminate processed foods as much as possible. You need a healthy diet of fish, vegetables, fruits, nuts, all that good stuff. We see the most disastrously low sperm counts in men who eat crap like burgers, shitty pizzas (by which I mean American style pizzas - Italian ones are ok, actually) basically abandon the stereotypical American diet completely.
Even going vegetarian is better for testosterone than the American diet. Believe it or not.
Secondly get more exercise. If you're overweight, get to a healthy weight. Strength and cardio both good.
These things tend to shift the average sperm count back up to a healthy level, or at least make you much better off than you would be otherwise.
Also, make sure the mother of your child does the same.

Are phthalates a fundamental component of plastics or some kind of additive that all manufacturers use to save money?

>>12761485
is well water ok?

>>12761513
well water has no plastics but it has shitloads of worse stuff.

>>12761501
>You need a healthy diet of fish, vegetables, fruits, nuts, all that good stuff
Done, mostly
>Secondly get more exercise
Reckon I'm good there

So basically just be healthy? I mean now that you mention it, it does make sense that sperm counts are down regardless of chemicals considering how fucking fat and disgusting so many people are now.

>>12761515
elaborate

>>12761522
heavy metals. test your water regularly unless you like lead poisoning

>>12761496
>>12761512
we're gradually phasing the worst of them out due to health concerns like this
that said, we really ought to be pushing to discuss this more openly, as they have significant effects on sexual development and nobody wants to touch the elephant in the room because of the demonisation of masculinity and the holy status of transsexuals
>>12761520
i'd cut the plastic bottles but yeah, basically just be healthy
you'd be amazed how disgusting the diets of most people are, people honestly do not consider what they eat in the slightest, and fixing that issue is a huge battle in the west but it's one of the easiest things you can do to boost your testosterone and sperm count
fast food has an enormous amount of phthalates in it, you can look it up

>>12761206
Could it be that Westerners (and Americans in particular) lead, in general, shitty lifestyles? Maybe microplastics and other pollutants have some effect, but being a fat sack of shit can't be ignored, I think. Do these studies control for BMI, drug abuse and related lifestyle variables?

>>12761545
could it be that's what literally the entire thread has been saying

>>12761206
Sonu even know the situation in East Asia and South Asia. Chink woman hate their chink male counterparts because they have feminine facial structure and short height. Why do u think so many chink females were filing for divorces in haste when the government announced that they're gonna make marriage and divorce laws more strict or so many women lining up for European sperm banks. On top of that working hours and conditions are fukin insane in China where the drastic reduction in sperm quality is sure to be expected and the 53:47 sex ratio makes things even worse.

>>12761585
Solid anecdote, except they've measured it as significantly worse in the West.

>>12761535
>i'd cut the plastic bottles
I've just been drinking water from the large bottles of spring water for the past few years instead of the small bottles since the water tastes quite a bit less like plastic usually but I wonder if that actually helps. Might be time to invest in a filter.
>you'd be amazed how disgusting the diets of most people are
I already am. got coworkers that bring in deep fried shit every single day and eat out every other day.
Fortunately I haven't had fast food in nearly 6 or 7 months out of not having a car. I've been having frozen garbage every month or so and I really should stop since I imagine it's the same thing.

>>12761585
I meant" do u even know"

>>12761583
Not in general. Some Scandinavian countries reported relatively little decline in sperm counts in some studies.

Not true.

https://www.researchgate.net/publication/323938608_Sperm_counts_in_Asian_men_Reviewing_the_trend_of_past_50_years
This present review also showed a mild time-dependant decline in sperm concentration (-0.44×106/mL/year, 95% CI: -0.65 to -0.23; r = -0.473, P = 0.040) which accounted for an overall 22.17% decrease in past 50 years.
>Conclusions: This study brings to the forefront that sperm concentration among Asian men follows a mild declining trend over the period of 50 years, and further studies addressing the causes of this decline are required.

https://pubmed.ncbi.nlm.nih.gov/11191086/
>Total sperm count, percentage of motile sperm and percentage of normal sperm observed in Kawasaki/Yokohama were significantly lower than those from all European centres except for motile sperm in men from Paris. >CONCLUSIONS: Japanese fertile men had a semen quality at the level of Danish men, who have been reported to have the lowest among investigated men in Europe. The low level of semen quality of the fertile Japanese men may be due to lifestyle or other environmental factors; however, ethnic differences caused by different genetic variation or combinations cannot be ruled out by this study.

>from Paris

>>12761624
Yes, read what you wrote.
>mild declining trend
in Asia it's ~20% over 50 years.
In whites it's ~60%
20% is manageable and easily reversible given it was over 50 years. 60% is not, especially when you remember that this is a cumulative effect. The next generation doesn't start over with a healthy sperm count. They start out with a similarly reduced sperm count, and then also get hit with a further reduction after birth.
This proves exactly the difference we point out.
>>Total sperm count, percentage of motile sperm and percentage of normal sperm observed in Kawasaki/Yokohama
this is completely different to a total decline. Again, total inability to read.

>this decline not seen
There is a decline. Whether it's as significant doesn't mean there's been no decline. It took me about 30 seconds to find two studies to disprove what you stated.

>this is completely different to a total decline.
Okay, glad to know that a decline in "total sperm count" doesn't count as a "total decline."

By western, OP means Europe and the United States of Jesus Christ but not latin america?

>>12761656
A 20% decline is not comparable to 60%. Nobody said absolutely zero decline is present in Asia.
Secondly,
>Total sperm count, percentage of motile sperm and percentage of normal sperm observed in Kawasaki/Yokohama
"total sperm count" does not measure decline. This does not measure decline at all. As the sentence immediately afterwards says,
>ethnic differences caused by different genetic variation or combinations cannot be ruled out by this study.
whereas the European decline has ruled out genetics. It is simply too rapid.
The European decline in sperm counts is about triple the decline in Asia. This is not a comparable situation.

>>12761668
>Nobody said absolutely zero decline is present in Asia.
You did. "This decline not seen in..." implies no decline, otherwise you should have said "this level of decline," but you didn't.

>"total sperm count" does not measure decline.
Are you smoking crack? Total sperm count, as in all sperm, declined, as well as the percentage of motile sperm.

>whereas the European decline has ruled out genetics. It is simply too rapid.
They've taken place over the same time period essentially, the last fifty years.

>The European decline in sperm counts is about triple the decline in Asia. This is not a comparable situation.
You sure are rapidly shifting your goalposts. Next time do a little research first, yeah?

Here's more for you.

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5637027/
>Following analysis of the data, a time-dependent decline of sperm concentration (r = −0.597, p = 0.02) and an overall 72.6% decrease in mean sperm concentration was noted in the past 50 years. The major matter of concern is the present mean concentration (20.38×106/ml) is very near to WHO cut-off value of 2010 of 15×106/ml. Several epidemic diseases, genital tract infection, pesticides and heavy metal toxicity, regular consumption of tobacco and alcohol are reported as predominant causative factors.
>This comprehensive, evidence-based meta-analysis and systematic review concisely presents the evidence of decreased sperm concentration in the African male over past 50 years with possible causative factors to serve the scientific research zone related to male reproductive health.

So there's decline in Asia, including Japan and China, and decline in Africa. I could check out South America and the Middle East, but I don't see a reason to at this point, your original premise has already fallen apart.

>>12761696
>otherwise you should have said "this level of decline,"
this is pure semantics which you're arguing only for the sake of being technically correct despite everyone being well aware what was meant
>total sperm count
was not compared across time
>They've taken place over the same time period essentially, the last fifty years.
this is very rapid, and does rule out genetics
>Next time do a little research first, yeah?
you just said you looked for 30 seconds online, and you seem incapable of even correctly reading an abstract in your haste to argue semantics
again, a 60% decline in sperm count in 50 years in the west does rule out genetic reasons, and we do not see this happening elsewhere
If I have to spell out (to anywhere near a comparable degree) to you then you're welcome to think you've proved some kind of point, but anyone with common sense knows this already, which is clear from the fact that people were discussing why the decline is lower elsewhere earlier in the thread (you were just the first dumb enough to think everyone else thought it wasn't occurring at all).

>>12761718
kek
>Several epidemic diseases, genital tract infection, pesticides and heavy metal toxicity, regular consumption of tobacco and alcohol are reported as predominant causative factors.
again, not what is going on in Europe, as in the European case heavy metal poisoning and epidemic diseases were controlled for when we see 60% reduction in sperm count
Perhaps you should stop rushing.

>>12761730
>That decline doesn't count!
Are fucking serious? You've gone from "this decline isn't seen" to "it's declining, but not as severe" to "it doesn't count because I don't like those causes." You're hilarious. Also, you never bothered to even link the original study, called other people lazy for not doing your work for you, and now you're claiming I'm being semantic when you're coming up with bullshit reason after bullshit reason why decline everywhere in the world doesn't count because you have some agenda to prove about the West.

I'm legit going to start doing runs into the mountains for veritable natural drinking water

>>12761737
It's been quite clear from context that when you have on the whole a roughly 60% decline in sperm count in the west on average that citing a study which looks at people with genital tract infections and who have been victims of epidemic diseases (which, again, were controlled for in the study posted in OP) are not relevant comparisons.
When you did post a study about Asian decline across a 50 year period (which did not have access to health, from reading it, but seems to have a good enough sample we might ignore that anyway) it shows only 20% decline in the same timeframe western countries declined by 60%.
Also, in the same study, it references other studies which reinforce the large gap between western decline and non-western decline. It's even in one of the earliest paragraphs.

>>12761206
>the median sperm count is set to reach 0

>>12761737
it's literally common knowledge at this point that chemicals in plastics and shit are feminizing boys more and more and it starts in utero
it's not that hard to figure out that that'll lead to a huge issue with men in the place with the longest history of exposure
also who's even attacking the west here? you can stick your head in the sand but this faggot shit and tranny culture didn't come from nowhere and there's actually a good case that it's these chemicals

>>12761730
>not what is going on in Europe, as in the European case heavy metal poisoning and epidemic diseases were controlled for when we see 60% reduction in sperm count
They excluded chronic diseases. Nothing was stated about epidemic diseases or heavy metals, pesticides were stated as a possible causative factor, and alcohol couldn't be accounted for because data for it wasn't available in the majority of studies. I think it's pretty obvious the major issue is pollution, mainly heavy metals and dioxins, which are part of the entire world's food supply at this point. It's not an issue of the West, it's a worldwide issue. Obesity could be another factor since it impacts hormone levels, and aside from Japan, obesity is highly correlated to GDP. Even with that as a factor, Africa obviously has a serious issue despite being dirt poor.

>>12761775
>it's literally common knowledge at this point that chemicals in plastics and shit are feminizing boys more and more and it starts in utero
Yup, and you're an idiot if you believe xenoestrogens and dioxins aren't in all of the world's food supply.

No one's blamed IVF yet so what exactly did they think was going to happen when infertile people started passing on their genes?
It'll fix itself when everyone who can't make sperm dies out.
High sperm count only matters if you rely on billions of dumb sperm anyway. Give them next gen egg seeking smart nav systems and you'll only need to make a few.

>low sperm counts can endanger human species

It's simple, you're wrong. You're just flat out wrong. I don't even disagree with your argument for what the possible cause of the decline is, but your belief that it's primarily affecting the West is moronic.

Let's just all set the standard that Transsexuals are a bad product to have in society

>>12761751
>and who have been victims of epidemic diseases (which, again, were controlled for in the study posted in OP) are not relevant comparisons.
This is incorrect. The study you didn't provide a link for did exclude chronic disease, but it did nothing to account for epidemic disease. I don't understand your line of thinking on that anyway. Africa has always had a problem with epidemic disease, so that should have nothing to do with the declining sperm counts. The same for chronic disease.

>it shows only 20% decline in the same timeframe western countries declined by 60%.
I also provided a study from China showing a 50% decline in a 10 year period, and a study showing Africa had a decline of 72.6% in the last 50 years. This isn't a Western problem, it's a worldwide problem, and there's no quick fix. Dioxins, furans, PCBs, and heavy metals take decades to remove from the food supply. Increased GDP leads to weight gain in nearly every country. Modern living requires desk jobs rather than physical labor.

How do I get drinking water without microplastics?

This is fucking stupid. Even if I have 50% the sperm count of somebody 50 years ago, if I nut raw inside a bitch on her most fertile day, I have a 95% chance of impregnating her.

So 50 years from now, even if people have 10% the sperm count of somebody 100 years ago, they can still impregnate somebody with 90% certainty on their most fertile day.

Sperm counts are memes.

BIG big doubt on the chemical cause. You really telling me that China has less pollution and cleaner water than the US?

I'm betting its a psycho-social thing. Porn addiction is prevalent throughout the west (In a US study 92% of men admitted to watching porn) and because of the neurological affects of being addicted to sexual super stimulus, you see things like Porn-Induced Erectile Dysfunction. It wouldn't be a far leap in logic to possibly attribute to also lowered sperm counts.

Going vegan is not better for testosterone. It is if you eat like shit then start eating vegan because you cut out a lot of hyper-processed foods.

A study done on the testosterone effects of onions had college age men working out then taking a protein supplement and measuring their testosterone levels before and after. The control (no protein) saw very small T gains, while casein saw larger. Whey protein produced the largest by a wide margin. Onions based proteins saw a reduction in free testosterone.

Idiots ITT saying that "third world countries" have it better are fucking retarded. We are far more exposes to harmful plastic on every day life than someone from a developed nation.

>Anyone want to guess how this problem will be solved?
High sperm counts are a solution to the problems imposed by what was originally, at the start of our species, a very high rate of human mortality contrasted to a very small number of actual humans. Fast forward about 30,000 years, and consider that in the first world, we have we have modern medicine, long life spans, no domestic wars, falling job prospects, rising costs of living and record-high populations, our problem today isn't how often and quickly we're dying, it's the opposite. That said, a decline in sperm production sounds like nature trying to solve yet another problem. Perhaps we've done this to ourselves?

That's rich, considering I just showed that you didn't read what I wrote to you, nor have you cited the original study you alluded to in your original post.

>You really telling me that China has less pollution and cleaner water than the US?
China's fucked. I pointed this out earlier. They've experienced a 50% decline in total sperm count in only ten years. See >>12761696.

We're evolving to become more efficent, which means less possible sperm combinations which means less sperm. It has nothing to do with tinfoil plots to turn men into traps.

>>12761875
It's not just falling sperm counts, it's also a decrease in the quality of sperm. Yes, you'll likely still impregnate someone, but possibly with an increased risk of birth defects because the sperm that made it to the egg was of poor quality. Also, sperm count and quality are tightly linked to hormonal levels and overall health, which means adult males are being exposed to something that's causing damage.

You're the one scanning abstracts to find a point you hope to make without even reading or understanding a word of it which is why you take 3 attempts to cite papers which have no direct comparison with the point everyone else is discussing and then totally fall apart when you can't give any argument against the chemical effects on germ cells stacking across generations (which very obviously implies we expect worse outcomes in the west)
Meanwhile your own study cites Carlsen and the like who show decline significantly worse in western countries, which you again didnt read because you only scan articles for abstracts which say stuff you like so you can outsource any kind of critical thinking skills.
You even got confused and compared decline in sperm count to a one-time measurement of low sperm count and motility. I think you should stop arguing like a redditor and either read the things you cite, understand what the papers discuss (you can't because you have no idea what you're talking about), and then discuss something rather than spamming abstracts of things you clearly don't understand.

Cheese (if you get a actually healthy kind) is actually quite good for your health.

Here are some good things to do to increase test levels and sperm count.
-Improve diet, best diet is a Mediterranean diet, especially eat lots of fish, even canned fish is fine and does not absorb BPA.
-Limit exposure to BPA and Phthalates
-Cold showers
-Exercise, and make sure some is outside.
-stop watching porn, and masturbating often.
-Limit time on technology each day and make sure you read (this is beneficial to your mental health, depression is linked to low testosterone and low sperm count.)
