A prolonged decline in male fertility in the form of sperm concentrations appears to be connected to the use of pesticides, according to a study published Wednesday.
Researchers compiled, rated and reviewed the results of 25 studies of certain pesticides and male fertility and found that men who had been exposed to certain classes of pesticides had significantly lower sperm concentrations. The study, published Wednesday in Environmental Health Perspectives, included data from more than 1,700 men and spanned several decades.
“No matter how we looked at the analysis and results, we saw a persistent association between increasing levels of insecticide and decreases in sperm concentration,” said study author Melissa Perry, who is an environmental epidemiologist and the dean of the College of Public Health at George Mason University. “I would hope this study would get the attention of regulators seeking to make decisions to keep the public safe from inadvertent, unplanned impacts of insecticides.”
Can’t wait to hear Alex Jones lie about this one, I hope aliens get involved again
Nah the chemicals in the crops are making the sperm gay, fellow policy wonk.
Big regrets not washing those blueberries before eating them now.
Depends on whether you want kids though. Free birth control, just eat more pesticides by never washing your produce!
Can’t wait to see someone say.
Oh I don’t need a condom I ate some unwashed raspberries earlier
It looks like the experiment itself was comparing sperm levels between direct exposure and indirect exposure. That tells us that high concentration and direct exposure reduce sperm and establishes the pesticide as capable of doing that. But it doesn’t tell us much about the global decline. Nothing in the article actually links the two together, and they haven’t even linked the actual study.
We know that some harmful substances are benign in small quantities. The everyday radiation we’re exposed to by naturally occuring isotopes doesn’t do anything. On the other hand, X Rays are safe, but the technicians actually have a noticeable increase in cancer risk if they don’t leave the room when they actually take the X Ray. So the latent background radiation there is enough to make a difference.
Ultimately, we still don’t know if the latent exposure we get to these pesticides is enough to cause reproductive harm. If there isn’t a scientifically significant difference in sperm levels between vegans and non vegetarians, I’m inclined to think this isn’t the culprit. But it’s worth further research and cutting back on usage anyway of course. It could be that we’re exposed to enough to cause a decrease in sperm, but not enough that dietary differences would be visible.
(This is why foods and consumer products can have incredibly complex molecules and still be safe. The concentration makes it benign – most of the time. This is why food additives are an interesting topic.)
Get outta here with your nuanced, well-reasoned opinions!

Just kidding. Great comment and analysis, this is why I love Lemmy.
I was told that we haven’t even established that there is a global decline in sperm numbers. That the methods of counting in the past weren’t as good as modern ones, meaning it isn’t a controlled variable of one time.
Also, a long the lines of what you said, I wonder if the number of people with direct exposure has gone up the past few decades or down. Less of the human race is involved with farming as farms have grown in size and output.
That the methods of counting in the past weren’t as good as modern ones, meaning it isn’t a controlled variable of one time.
That’s actually mentioned an article.
That saves me a shitload on a vasectomy.
Just drink Roundup!

Another round of Roundup?
Vasectomies are actually pretty inexpensive.
This is fantastic news, all the better for the planet 👍
Glyphosate is stored in the balls
Im a little offended that Monsanto thinks my sperm are insects if I’m being honest
Is this a bad thing? Fewer kids in the future seems like a win.
There’s no fda approved male birth control because everything they’ve tried to specifically target fertility has other unacceptable side effects.
So view this as a canary in a coal mine scenario. This is one aspect of health that’s easy to measure, but without further study we cannot assume that there aren’t other more severe health complications associated with exposure to pesticides.
That’s funny since there’s countless negative side effects to female birth control
What are the unacceptable side effects to a vasectomy
Sterilization is not equivalent to birth control. To be considered birth control, fertility should return shortly after the cessation of usage. Since vasectomies are considered permanent it’s not in the same category.
Although, that’s beside the point, and I’m pretty sure you know it and are being cheeky. The point is if researchers trying to target just fertility with no unwanted adverse health effects have a hard time developing such a drug, then we should assume that it is very likely that substances that cause decreased fertility are also causing other adverse health consequences.
Depends if the economy can cope with the shrinking labor force and demand. And who is going to take care of all these old people. Unless we have automated a large part of our economy by then either we’d be fucked or the developing nations will be exploited even harder.
- automate
- cut down the bullshit jobs
- ?
- profit for the people
African overpopulation was seriously overweighted back when people were talking about global warming in the 00s.
It’s never been an issue we didn’t have solutions for.
It’s not for countries with shrinking populations. The most sustainable model is a roughly constant population, which we’re going to reach sometime within the next 50 years. A shrinking population means an aging population, which comes with its own host of issues (see: Japan and Korea).
Next stop: children of men
Given the role reversal, wouldn’t it be Children of Women ?
Either way, whatever drops the pop … ulation.
Lets get it into the drinking water.
Good news: it’s “microplastics” and it already is!
You’re an idiot and a psychopath.
Sperm Motility issues 😪

It’s purely anecdotal, but go to a small town in Iowa and you may notice something a little unexpected - there’s seemingly a larger than normal population of gay and transgender people.
Again, anecdotal, but I visit there frequently for work. My gut tells me the crop treatments are screwing with hormones…unless there’s some other explanation.
Proooobbbbably that those folks finally feel remotely safe being “out”
“I visit there frequently…for work…” 😏
Sure thing, Alex.
People mock the gay frogs thing, but pesticide runoff was mucking with frog hormones, causing a genuine physical sex shift. Frogs are capable of shifting sex under specific conditions, and the chemical pollution was forcing the change. Huge ecological damage.
It was perhaps the single time alex jones was correct about anything, and if he hadnt called the frogs gay he probably wouldnt have been mocked for it.
It was making them trans, not gay.
They do that anyway if the population ratio is off by enough, but yeah they transitioned much more rapidly and more often. They also would excrete everything at once so currently male frogs would read another current male as a mate. Technically it was a grain of truth with zero nuance
I honestly wonder if being exposed to xenoestrogens in the womb is why I’m trans.
I’m not unhappy about it, just something I think about!
I grew up in Iowa, and I live in a large Ohio city now. There are barely any LGBT folks in Iowa, even per capita, it’s just not normal or accepted there en mass. There was literally only one gay kid in my high school of 1500.
I move to Cleveland, then I meet more LGBT people than I have ever seen in my life, even having 4 lesbians in my workplace and one FTM.
But social media is probably the biggest driving factor behind the rise of so many LGBT people in the past decade.
You mean there was only 1 kid who was “out”
Observation bias I imagine that and the more open society. There were always LGBT people, they just were in the closet when the theist were determined to murder them.
it’s also the cosmetics that contain a shitload of hormones or stuff that messes with hormones, that causes a behavioral shift in society.
It’s well known the elite has depopulation plans running already in the alimentary fields.
Well shit, what can we do?
Organic food only maybe
They still use pesticides growing organic food.
Organic food typically has more pesticides, since gmos are often attempting to remove the need for pesticides
Also organic farming relies on old types of pesticides instead of the modern ones which are designed to be more effective and safe.
Have a source for this?
FDA, EPA, and the Department of Agriculture. Pesticides and drugs are both heavily regulated and new ones do not gain approval or even make it through early test phases unless and until they can demonstrate equivalent or better efficacy compared to existing alternatives, with equivalent or fewer side effects and environmental hazards.
This depends very much on the country you are in - perhaps that’s the way it works in the US. But in the UK Soil Association standards limits the kin dof permissable pesitcides and how they are used quite strictly: https://www.soilassociation.org/media/23378/gb-farming-growing.pdf - see page 63 onward
Source?
Any farmer? Including me?
Organic is nebulous, first off. But depending on your region, the organic label just makes some specific pesticides off limits. Which means we over apply the stuff we can use.
There isnt a modern produce company on the planet who doesnt use pesticides. You cant compete otherwise. Only pesticide free foods are locally grown by very very very small gardens and farms.
That’s one solution, but even being more careful with what pesticides are used would help in this case (though it would still be devastating for the insect population and will come back to bite us in other ways)
Who cares? Kids suck
