Sperm Counts Among Western Men Have Halved In Last 40 Years, Says Study (theguardian.com)
New submitter flote shares a report from The Guardian: Sperm counts among men have more than halved in the last 40 years, research suggests, although the drivers behind the decline remain unclear. The latest findings reveal that between 1973 and 2011, the concentration of sperm in the ejaculate of men in western countries has fallen by an average of 1.4% a year, leading to an overall drop of just over 52%. The study, published in the journal Human Reproduction Update by an international team of researchers, drew on 185 studies conducted between 1973 and 2011, involving almost 43,000 men. The team split the data based on whether the men were from western countries -- including Australia and New Zealand as well as countries in North America and Europe -- or from elsewhere. After accounting for factors including age and how long men had gone without ejaculation, the team found that sperm concentration fell from 99 million per ml in 1973 to 47.1 million per ml in 2011 -- a decline of 52.4% -- among western men unaware of their fertility. For the same group, total sperm count -- the number of sperm in a semen sample -- fell by just under 60%.

My father and both grandfathers always got a full week off each year. I haven't had an entire week off since graduating from college in 1986. Also, they only worked a little over forty hours a week. Other than around Christmas, I don't think I've ever worked that little in any week of my adult life. It takes its toll.

This is hype news. Like Ehrlich and his Population Bomb but now it is the Population Unbomb. Nature massively overcompensated with millions of sperm and only ONE is needed for conception.

Blame creimer for jacking it when he was 7 years old. The rest of us are traumatized since he made us watch.
Millennials have this really disgusting complexion,all pale and ruddy like a pregnant fat girl from Topeka. They also these weird oblong squidward-potato features. When they grow their "beard" it comes out looking like some FTM transssexual, all potato face and effeminate. Honestly it's been a long time since such schlubby, faggy-looking creatures have roamed the planet, with their stunted malformed XXY genitals. Really disgusting, TBH.
Phyto-estrogens, found in a number of meat/milk substitutes, have been blamed for years but no-one is studying the effect of these ingredients.
Impregnation is a numbers game: So the sperm needs to have the quantity to get through the minefield that is the female reproductive system and deliver a few healthy spermatozoa (most aren't, numbers) to the ovum. That's usually been regarded as 200 million sperm as a blanket assumption. That assumption can be incorrect if the female system has also evolved to be less toxic to sperm.
See subject: What you said's funny enough but WHY are you constantly crapping on creimer for? Seriously. Why??
* I've "had it out" w/ him before but he's not all that bad really so I have to ask WHY you're constantly ribbing on him for... yes, I've stuck up for him as well once vs. your ribbing (yes, probably was you).
Another e.g. - I see you say how "fat" he is etc. - do you KNOW that for a fact or are you projecting your own issues onto him? Don't take offense to that. I'm curious. Folks have a habit of that (think about it - I call you, say, "fag" - but you KNOW you're not so it 'bounces off you' but it'd PROJECT what hurts me or bothers me about myself...)).
(I have a few "troll fans" like you are to creimer but I know WHY they do it to me & WHO most of them are as far as "registered 'luser'" names & some in REAL life as to who they are, where they live, etc. (they're harmless & butthurt over me blowing them away on tech issues they must've thought they were 'all-knowing God' in & I proved otherwise...)).

Did they control for urban vs. rural populations, white collar vs. blue collar occupations (more specifically, sedentary seated jobs vs. active standing jobs), and BMI?
Urban lifestyles in themselves (crowding, chronic stress from noise, light pollution etc.) have been shown to affect testosterone production and by derivative germ cell count in some studies. Similarly, sedentary jobs and being overweight reduce test and germ cell count.
In fact, I'd be surprised if sperm counts were -not- lower across the general western population over the last few decades.
Packing people into cities and moving to a service economy is the other half of the birth rate decline coin- the first half being lowered desire for children as a social norm.
The drop in Human fertility, and the fall in the average age of puberty, in nations that suffer the 'age of plastics' and the 'age of intensive farming' is the most significant scientific story about the future of Humanity in the last one hundred years- yet gets near zero coverage. Unlike the scares organs like slashdot push daily (to promote pro-war and orwellian policies by the neo-liberals), the change in the Human condition is beyond dispute.
The main problem is that Americans live quite happily with abusive scientific experimentation on the population. Yanks love their 'built like a fridge' high-schools football players, but never question the abuse of the same hormones that bulk up cattle used on American boys. The Deep State in the USA loves that hormones in American food gets into American kids.
Then we have the Yank love of baseball- with Americans never questioning the poor parents who abuse Human Growth Hormones to artificially increase their kids height in the hope they'll become high-earning stars. In most of America a poor black mother can go to her doctor and claim that little 9-year-old Johny isn't growing fast enough. Most Yanks are so thick, they think all those tall black basketball players just grew that way 'naturally'- same as Yanks think they are anti-drug use in sports while ignoring the essential chemical methods required to build muscles in any sport where excessive muscle bulk is essential.
This abuse of chemicals in the USA makes the USA an engine of denial when it comes to the fertility and puberty disasters- for American 'scientists' argue that if you took the factors that are causing the fertility and puberty problems seriously, you'd end up having to expose the quite deliberate programs of chemical 'alteration' of American children in the name of 'sport', the military etc.
What Yank ever wonders why American children are uniquely susceptible to 'allergies' or 'attention/behavoral' problems when compared to any other nation. Yanks are made so thick by their press, they honestly think the rules of science literally change in their nation.
Anyway, what we do know is in the West, we allow terrifying chemicals to flood into our drinking water and food. Much of this is driven by the age of plastics- and since plastics are 'organic' chemistry, living tissue has a baked in vulnerability to many organic chemicals. And the intensive farming of the West puts another raft of chemicals into the Human diet.
When fertility rates drop, social factors also matter. If traditional westerners are already significantly changing the size of their families downwards (later marriage- more parents wanting just one or two kids), a drop in fertility can end up meaning no kids at all. Meanwhile the new 'immigrants' who come from cultures wanting as many kids as possible will tend to mask the drop in fertility with the effort they put into procreating.
In nations like Britain, the Deep State is now openly admiting it opened the floodgates to immigrants precisely because they will have far more kids- helping 'pay' for a rapidly increasing elderly population. Of course this is just an excuse. The real reason was that the native population was never going to willingly vote for the orwellian policies desired by the Deep State. The Deep State has arranged a cultural invasion of West Europe that ensures in 50 years time the common culture there would be utterly alien to someone from the 1960s. A plastic pliable 'religious' population breeding vastly greater numbers of 'cannon fodder' units - as we now see in all muslim nations destroyed by Saudi Arabian wahhabi terrorist in league with the US military.
Thus the fertility disaster becomes an irrelevant 'white person' problem- that organs like slashdot will claim only 'trump-supporting' 'racists' care about. The Deep State in the West rejoices in the drop in the age of puberty because the immigrant flood is not 'modernised' but encouraged to hold onto 19th century principles of family, like arranged marraiges, early marriages
Probably just the men in the western world getting their balls too hot. No big deal really. Search for "Genital heat stress and semen quality".

Increased sexual equality and decreasing importance of marriage in Western countries have strengthened actual monogamous relationships, at the expense of nominally monogamous marriages (avoid social stigma, requiring a breadwinner when one partner is excluded from the workforce, etc.) that lack emotional connection and lead to partners straying. This means there is less need for sperm competition to ensure heirs, therefore the selection pressure is on lower sperm counts and redirecting those resources elsewhere.

P.S.=> One of my best pals weighs, no shit, 450lbs - now He's FAT (he doesn't like hearing it though) but I could care less personally - he's honest & you always know where you stand w/ him (for the most part). That's WHY I consider him a pal (who cares how somebody looks UNLESS they're UGLY INSIDE too. Hey, I've met women who @ FIRST I thought "Oh my God are you sexy" UNTIL I got to know the REAL them & their TRUE "ugly" overshadowed their physical beauty totally)... apk
Like some other guy for instance.
There is a whole subculture around that.
See subject: You're just f'ing around & not serious. He left a link in reply here so even IF he's fat he isn't ashamed of it obviously. I could care less if a dude's fat (one of my best pals since 2004 is HUGE fat in fact & I noted it in my reply to him). Yes, I will use it against someone who gives me guff, but it's more about the "internals" of someone's persona imo. You can be beautiful/handsome outside, but UGLY as hell inside & it radiates out over physicality imo.
HOWEVER: Women I do though (lol)!
Speaking of which: IF he is a virgin? In a way, I ENVY him. Women (well, me really) have made me a "broken sad defeated abused man" as I didn't know how to handle it well early on so... in a way, he's avoided ALL that madness & lunacy (think about it - perhaps you've never been there & were TOO SMART to play/chump yourself, but admittely, I have - 1 of the worst experiences in my life).

That is the only logical explanation for this. Women are fucking impossible to deal with anymore. They cannot be satisfied no matter how much money you make, how much you work out, how much stuff you have, or how popular you are. You're never good enough.
It gets to the point that you don't even want to reproduce with them anymore, and so your body's like "whatever, Ima shut down this sperm factory down here and use my energy to get better at minecraft instead."
Not long ago a friend of mine and I were having a beer and he asked me, "you know, my wife thinks you don't like her; you never talk to her and blow her off when she tries to talk to you." And my response was, "she's right." I actually loathe the idea of interacting with females in any capacity. It's actually pretty fucking great, because it's so much less stress in my life. I'm not constantly having to walk on eggshells and jump through hoops.
Drop in men's sperm counts match up perfectly with the rise in feminism. Wonder if rather than due to some type of physical or environmental effect, it could be psychology affect men's sperm counts...
In a longitudinal study that follows the same male subjects over the course of 40 years, OF COURSE sperm counts are going to drop. That happens when you get old... ... dumbasses. And this is what we call "science" today. It's no wonder we think the Earth is a runaway oven and that all of our medical ills are caused by gluten.

Estrogen mimic plasticizers are all over the environment. They're in your clothes, your bottled water, your food, the chairs you sit in, ETC.
They would be my first guess as to the reason for many abnormalities, and certainly for something involving sperm counts.

I blame feminism. They have already cut of an average of one ball from every American male, halving the sperm count. When they are through cutting off the other ball, the sperm count will drop to zero. A few decades later, American will be populated only by parthenogenically propagating lesbians.

Many plastics interact with the human body in the same way as estrogen. RBGH also interacts with the human body in the same way as estrogen. Not only does this result in lower sperm counts, but if it makes it way into the fetuses of pregnant women, it can cause gender dystopia (aka gender identity disorder). I would not be surprised if we discovered that the number of gay males and trans humans has been on the rise, even after accounting for greater rates of gays coming out.
After accounting for factors including age and how long men had gone without ejaculation
Hmmm, I'm sure that men in the western world wouldn't lie about how long they've gone without ejaculation.
Western men sperm count low?
No problem !
Just import more Muslim Men into the Western countries and the mean sperm count will inflate, magically!

Over the last few months several Science reports were released, each dealing with the subject of drugs, water, and gender.
Many people take prescribed medication with no thought of what they do to the body, how they are used, or what actually becomes of them.
As example, when we ingest vitamins, our bodies take what it needs and the excess is passed out of the body via urine an excrement. Therefore, these excess vitamins end up in our water supply.
The same is true for medications dealing with high blood pressure, diabetes, Anti-depressants or Anti-Psychotics.
Approximately 70-80% of these medications are passed through and end up accumulating in the water system.
For the last 10-12 years, Anti-depressants have been over prescribed and the number 1 medication prescribed by doctors in the US.
I read a science report a few months ago of large amounts of Anti-depressants being measurable in our drinking water.
These were also detected in the ocean, which means the levels must be pretty high if they can be measured in an ocean.
Scientists also noticed a change in the ocean wild life. There were a variety of fish whose gender was being drastically altered by these drugs, with some male fish even developing female organs.
I wouldn't be at all surprised if this has also contributed largely to the sudden emphasis of trans-gender alteration we are seeing in humans for the last 10 years.
Surely, the EPA and FDA must have noticed this change in our water supply. The question is, why haven't they responded by protecting the citizens?
Personally, mines still 100% because I was 2, however, maybe males are having sex more frequently... so that the stores of sperm don't get to their full load (unintentional pun) before the next delivery?
Either way... a joyous day...becuase now males can claim that they have to have sex twice as much for the same outcome.
It's because we don't play enough football.

> and for non-western men? ... What's been happening with them?
I think you are asking about "developed" countries outside of the "Western" or graeco-roman-christian cultural tradition (because we know "developing" third-world countries have no problem producing a huge number of newborn babies every year).
Anyhow the situation in e.g. Japan is even more disastrous, they are on the verge of abyssal demographic collapse, with just 1.2 reproductive rate (even though 2.1 would still be mere sustainment of headcount). Japan too has the sperm count problem and furthermore: their boys never grow into men, but keep jacking off compulsively to 2D anime / manga / game girls, like Idolm@ster, while japanese girls grow into lone ladies who keep cats instead of husband and kids.
The all pervasive and heavily propagandized "j-pop" culture has also taken a bizarre and dangerous direction in the last 15 years or so: on the face of it, it still idolizes girls (the "seifuku" mini-skirt schoolgirl heroine stereotype) but in fact the stories just preach expendability and replaceability of girl characters, scripts are more and more angsty just for the sake of angst and usually the survivor is the boy, not the girl. This teaches boys commitment is unimportant and also teaches girls that boys cannot be trusted to keep their promises (I will save you, I will make you happy! Marry me... girl is slaughtered next day...) Societal peer pressure forces almost everybody to watch anime junk in Japan and what they see takes a toll on the population's mental state or even health.
It also doesn't help that divorce law in Japan is terribly unfair to the women, i.e. the husband can walk away any time, without paying a dime, provided he doesn't want to see ex and kids ever again. Furthermore the structure of japanese language differs a lot between male and female speakers and so their guys address the ladyfolk in rather (c)rude terms. Now that japanese girls are also getting good quality public education they are less and less willing to accept being addressed almost as an animal and just shun contact with malekind.
(This is not a joke, I've read several foreigners reports which coherently claim that having a vocabulary of just 150-200 words and saying 5-10 basic kind sentences to young japanese women essentially made them melt out of their pantsu. They have never been fawned or even addressed with true respect in their whole life by a member of the stronger sex! Apparently japanese men are really unsure of themselves over and under the beltline and express that in verbal arrogance towards the ladyfolk.)
We do less male stuff, plain and simple. Testosterone is down from sitting on the couch, getting fat, drinking to much beer, stimulating with videogames rather than real stuggles and not work harder physical labour as we used to. Porn feeds an epidemic of erectile dysfunction that has to play out into sperm quality and count at some point. And on top of that the guilt-show western males have to go through hamper true male heterosexuality - a very important aspect consistently left out of this shitty ongoing gender debate that seems to totally ignore hetero males other than in shaming them.
Anecdotal point in case: I startet social dancing (Tango) about a decade back. Curiously, this old-school supposedly macho dance is consistently overbooked with often very well educated women who apparently really desire a strong man to hug and lead them at regular intervals. I just came back from a Tango trip to Moscow two days ago, which drove this impression home tenfold for me once again.
Anyhow, after starting Tango I started to finally get the encounters with women I had so desperately desired since my teenages, often just consisting of firmly hugging a beautiful lady for an extended period of time, and soon noticed my body hair getting significantly darker and my voice lowering. Clear sings of testosterone going up to normal levels. That, as you can imagine, actually did amp my attractieness to the ladies quite a bit.
Now being in my mid/late 40ies I'm also slowly getting a grip on the "male guilt" thing that comes with growing up in an often wrongly feminist society. I'm leaving nerdy escapism more and more behind (Slashdot being still one of the exceptions) and have by now had enough sexual experiences to finally feel OK as a white hetero man. Not perfect, but OK. The guilt thing withdrawing includes a healthy perspective on porn and masturbating (i.e. not that spectacular as the real thing and often not worth it) which actually go back to 'normal' levels once confidence sets in and there is emotional room for escapism and numbing to retreat.
Long story short: We basically lack most of the natural environment that makes men men and have to work it out in other ways. Ad in fathers either chickening out of their responsiblities or - as in the US - too much in a legal risk to get married these days and you completed the picture. That sperm count goes down in these times comes as no real surprise to me.

I get what you're saying, but it honestly isn't very unusual for women to melt out of their pants if a foreigner compliments them in their own language, no matter where you are. Women are always somewhat interested in bringing exotic genes into the local gene pool, it's a basic evolutionary tactic to avoid inbreeding.
If the trend continues, there will be a day when Western Man is no longer able to produce sperm at all.
But fear not, humanity! Thanks to frozen sperm, bulls that died years ago are still fathering calves. With my high IQ and 6' 2" manly-man size, I am willing to contribute now to save First World Man from extinction.

Amen. Once you start thinking about where plastic is found, and the precious few places where it isn't found, plus as you say known estrogen mimic properties (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3222987/), it's pretty hard not to see that as a the culprit.

In 1970, my step father told my younger brother that if I did anything he didn't like, he was to kick me in the balls, repeatedly. In 1973, he told his son, my half brother, the same thing, so in my case, my sperm production has suffered probably due to having been kicked in the balls a few hundred times between when I was 10 and when I was 17.
1. Someone mentioned obesity, which does lower fertility.
2. Oh, and need moar guns, gotta protect ourselves against, um, against people who don't live here, who... make sure that we're TERRIFIED, SCARED SHITLESS ALL THE TIME, and that cuts fertility.
3. Finally, it sure looks to me like the studies they did in the sixties and seventies with rats on overpopulation. Once it hits that, you get fewer kids, more craziness, cannibalism... hell, you might have a psychotic elected President!

Can the woman do the same? If yes, it sounds pretty fair to me.
By far the most likely cause of lower sperm count in western men is... western women! Testosterone decreases in proportion to how low you are on the pecking order. Western men have been told they are total losers for decades. Result: lower sperm. Western women, though, have increased their sperm count, or so it would seem.
Not just plastics, I would guess it's also all the chemicals in processed foods that has long term effects.
our increasingly sedentary lifestyles. I would really like to see a study where counts are compared between people who exercise regularly and those who do not. I would further like to see such a study broken-down by type of exercise, such as bar bell strength training vs cross-fit vs pure cardio vs just using those Nautilus-type machines at the gym.
Too much methane
This has nothing to do with technology.
Boy is this comment section full of highly educated, well respected, nutrition scientists who can all tell you precisely why this is happening. Weird that they contradict each other though.
It's probably oral contraception. It seems each generation is much less fertile than the last. Pretty soon everyone will be sterile except those that didn't believe in it and followed natural family planning. That's what happens when you separate the sex act from procreation and make it a sterile act. When you mess with natural law, there will be consequences.
I agree. The explosion of plastic in everything, wrapping everything, items impregnated (no pun intended) with anti-bacterial chemicals and what not. What they should do is measure men for the amount of chemicals in their bodies. Perhaps you'd see a correlation worth investigating. Since the 1940's we have been creating artificial substances that are never tested, often are used for thing different that what was planned (artificial sweetener was originally rat poison), these substances mix together in ways that can't be tested or even thought of TO test, chemicals are added to foods, etc. etc. What really pissed me off is the long list of chemicals that were banned in Europe, but still OK here. What do they know that we are ignoring because of politics or money?
Given the overpopulation issues we're heading toward, is a decreased sperm count such a bad thing?
It is THE most adulterated food supply int he world.
You can't even know what's IN the products you buy because of the shit labeling laws favoring corporations.
You should be upset. You should be outraged. You should be demanding a stop to this absurd corruption. But you're like all Americans, you remain silent. You deserve to die off.
No it wasn't!
Robots don't need sperm. Humans will die off in the robot apocolypse.
^ this BPAs and similar other toxins in the environment will be our slow undoing. It'll be just slow enough that we'll let it happen before doing anything to prevent it, just like climate change.
Well, at least you have an understanding of the difference between a plastic and a plasticiser.
Birds are not dinosaur descendants;birds are dinosaurs, for all useful meanings of "birds", "are" and "dinosaurs"
I don't see any big problems either. It'll take time (generations, literally not figuratively) to work through the demographic pyramid, but reducing fertility is an obvious requirement on a planet of finite resources and with an individual desire to not die young.

Ridiculous. My sperm count decreased by 100% in the past 40 years. In fact, it decreased by 100% over a few days in 2001, and it's stayed at zero since.
Since this is Slashdot, I'm assuming my anecdotal experience counts as compelling evidence for the general case.
