Infertility in Spanish Pigs Has Been Traced to Plastics. A Warning for Humans?
National Geographic Magazine ^ | 6-5-2014 | Josie Glausiusz

Posted on 06/18/2014 4:33:09 PM PDT by Renfield

A strange catastrophe struck Spain's pig farmers in the spring of 2010. On 41 farms across the country—each home to between 800 and 3,000 pigs—many sows suddenly ceased bearing young.

On some farms, all the sows stopped reproducing. On others, those that did become pregnant produced smaller litters.

When investigators examined the sows and the semen that had been used to artificially inseminate them—it had been collected from different boar studs and refrigerated—they couldn't find anything wrong. The sperm cells weren't misshapen. None of the sows were diseased. No microbes or fungal toxins were detected in their feed or water.

Only one factor was common to all the farms and studs: The plastic bags used for semen storage all came from the same place.....

Magapor had purchased the semen storage bags from a Chinese manufacturer. When the company switched to a different bag producer, the Spanish pigs’ fertility returned to normal.

Don’t get me started on soft drinks ,, the original artificial sweetener that was banned ,, the cyclamates , tasted great and were later proven to be harmless.

It's too bad the can't work these Chinese plastic bags over to our wild pigs in the South. There's an epidemic of hogs in the woods, fields and swamps and they're out-breeding even the hunters.

Damn fertile Myrtles!

The day will come that factory soy can no longer be protected.

I avoid raw soy... which is hard as “they” put it in everything...

I also believe it makes people “vote poorly”. Bwhahaha!

Perhaps there is something to Weston A. Price’s studies, afterall?

How much of our food supply and pharmaceuticals comes from China. I’m sure they’d never engage in ‘shenanigans’ with any of that.

20 years ago the largest city near me had one part time fertility doc located in a major ob/gyn practice. His patients (he’s a friend of a friend) were 2 types (ok, 3). They were either the 35+ who forgot to have kids, the 20 something or early 30 something who had reproductive damage from an STD or tubal ligation and changed their minds, or they were damaged due to DES.

Now, that same city has grown by about 20% populationwise. However, now there are SIX fulltime fertility docs. They have patients in the above mentioned categories along with a whole host of men who have no swimmers or have too few to do the job or have defective swimmers. Along with a whole bunch of seemingly healthy couples who are infertile for ‘we have no idea why you can’t get pregnant...’. The latter group contains a lot of mid/late 20 somethings. The waiting list at those fertility specialists clinics run from 3-6m for an initial appointment.

I’m about 15yrs older than that particular demographic. When WE were in our late 20’s we’d never heard of someone being infertile. And we were hardly getting married off in our late teens either. Many of us waited till our mid/late 20’s to become mothers with absolutely no problems. Infertility was for someone ‘damaged’ or some sad 40yr old. In our group (and it happened more than once), if your boyfriend hung his pants on the chair you MIGHT be a mama 9m later. It’s not like that for that age group now.

Even the teen pregnancy rate has crashed. Significantly. Even among the demographic for whom a teen pregnancy is a ‘career move’. They’re not having babies like they were 20 years ago. And you’ll not convince me it’s because they’ve all suddenly decided to go to junior college. I know better than that...Ditto trying to convince me they’ve stopped having sex or have suddenly become responsible about using birth control for some reason.

And all those abortion clinic closings? As much as I’d like to believe it’s because the women suddenly decided en masse they’d rather keep the baby, I suspect based on the aforementioned data it’s because even unwanted pregnancies are becoming increasingly uncommon.

The question is, why? I fail to believe it’s because a generation of kids wasn’t spanked appropriately and somehow the participation trophies have stolen their fertility.

You have grown older. I am old enough that my parents were of your grand parents generation. My father’s high graduation picture looks about the same as mt brother’s and my daughter’s friends. You have an axe to grind and I am not sure why. The studies you cite are meaningless and your personal observations, while interesting to you, are anecdotal.

Your views on child rearing are strande

I have no ax to grind. I merely notice the differences between kids in my generation and those of today. Today’s young males are WAY more effete than those of even 30 years ago. They are also way more infertile.

Sperm counts are halving every generation. That’s not normal. Or healthy.

Lots more out there like this one.

As I said, the effect is most noted in those who have rural grandparents. As compared to the grandkids today.

Incredible. I always hoped that you would be wrong about this, but it sure ain’t shaping up that way.

And the bit about the local fertility docs is something I learned a month or so ago.

In less than a generation, the need for ‘fertility services’ has gone up 6 fold. Actually more than that, the guy who was the fertility doc 20 years ago only did that part time. And the age of those seeking services has gone down. Wonder how much of that is due to guys with no, or defective, swimmers.

Actually your choice of words show exactly where your bias lies. Because you view these young adults as ‘more effete’ it must be true. I already gave you observations from my experience (which interesting enough I can really on my parents, my siblings, and my children for DIRECT observation).

You cannot provide any data to show that males are more infertile than before ( because the fertility rates match those of the Great Depression). People choose to have children for many reasons. Again you cannot show that sperm counts are halving every generation.

What I get from your posts is that you don’t like where modern society is going. Okay but please don’t ridiculously blame it on plastics,etc.

Really an article from the LA Times that includes such scientific ‘evidence’ as the following “But finding such super sperm isn’t as easy as it used to be. Only 1 in 100 donors makes the cut. A decade ago, it was 1 in 10.

And it’s not just first-rate sperm that’s in short supply. All of Israel’s half a dozen or so sperm banks are scrambling to keep their liquid-nitrogen freezers stocked.”

Now analyze that bit of information....Are the same number of people still donating sperm? Doesn’t say. Is the age of the do not (on average) the same? Why are people in general no longer donating to other sperm banks (that don’t reject sperm that isn’t super)?

And don’t bother with any more articles because they really aren’t supporting your thesis. Your biases are clear. Your anger is also clear.

I can 'prove' that cigarettes are totally safe because no one in my family has ever gotten cancer. Of any sort. In spite of most of them having smoked 3 packs a day of unfiltered camels for 60+ years.

I like modern society just fine. I looooooove men. Especially masculine ones. Those are becoming the modern day Dodo bird in the under 30 age group. I despair of my daughters being lucky enough to actually find one.

Look at the high school yearbooks. That's a way more representative sample than your own specific family. Even my 70+yr old mother has noticed that the little boys today are very very 'pretty'.

And do read the articles I helpfully provided in the links.

http://www.foxnews.com/health/2012/12/05/french-men-not-producing-as-much-sperm/

"Researchers found that between 1989 and 2005, the number of sperm in one milliliter of the average 35-year-old Frenchman's semen fell from about 74 million to about 50 million - a decrease of roughly 32 percent."

http://www.sciencedaily.com/releases/2010/11/101128194013.htm

"Sperm counts have dropped significantly in the last 50 years in developed countries. Today, at least one in five 18-25 year old men in Europe have semen quality in the subfertile range. Testosterone levels are also declining. This is mirrored by increasing testicular cancer in most industrialised countries and more developmental abnormalities such as undescended testes. All of these factors are linked to reduced fertility and may have common origins during foetal development."

You clearly don’t know any fertility docs.

They are openly talking about it.

They’re not angry however, they’re counting the money they’re sweeping into their bank accounts left, right and center.

Fertility was a backwater specialty just 20 years ago. Not anymore.

But keep your head in the sand. Not everyone will live to be an ancestor.

This guy is a Danish researcher who seems to be doing a lot of studies on androgens and their effects.

It would be really great if this was global warming quality research. Given the jump in fertility docs I suspect it’s not though.

Then read what some of the reports are that also take issue with the methodologies and conclusions
