Kiwi men on track to have zero viable sperm by 2040 - scientist

A scientist studying human fertility has warned Kiwi men's sperm counts are dropping so rapidly, within a couple of decades there might be none left.

In 2017, Shanna Swan - an epidemiologist at Icahn School of Medicine at Mount Sinai, New York - co-authored research looking at falling sperm counts in New Zealand, Australia, Europe and North America.

Looking at 185 studies dating back to 1973, Dr Swan and her team found a 50-60 percent decline between 1973 and 2011.


It was sparked by a paper she saw while on sabbatical.

"I spent six months... looking in detail to see, was this decline due to different method of measuring sperm, or recruiting men, or where they more obese or did they smoke more?" she told Environmental Health News this week, promoting the release of her new book Count Down: How Our Modern World Is Threatening Sperm Counts, Altering Male and Female Reproductive Development, and Imperiling the Future of the Human Race.

"Were there other things that could explain the decline? After six months of work, the answer was no. The slope had not changed after all that analysis."

So she started the proper research that would result in the shocking 2017 paper published in journal Human Reproduction Update - which found the decline was indeed real, consistent and showing no signs of slowing down.

Dr Swan says at current trends, it's on track to hit zero between 2040 and 2045.

"What does that mean? These are median sperm counts - which means half the men in Western countries will have no sperm. This is a big problem, if it were to come to that... If things continue in the same way, it looks very grim for our population survival."

Similar drops in sperm quantity weren't seen in men from South America, Asia and Africa - the scientists unsure whether that was significant, or just because they didn't have enough data from those regions.

So what's behind the drop in Western men's virility? The initial study didn't go into that, but she does in the book.

"I think everyone agrees this is not genetics - this is too fast for an evolutionary change, we're talking about 40 or 50 years," she told Environmental Health News, saying that environmental and lifestyle factors are likely to blame - including the effects of pesticides, cosmetics, foam furniture, paper plates, work stress, fatty food, processed food and packaging.

"The chemicals I'm particularly interested in... are those that affect the body's hormones. The reason is that reproduction depends on healthy hormones. Anything that would interfere with the body's natural hormone system... is going to challenge the reproductive system."

"If women want to have a baby, they are often told, 'Clean up your act,' " Dr Swan writes in the book. "But it's probably more important for men to do so."

No .. for one thing she has not carried out research ., she has just analysed data from historical reports .. there is no breakdown of age ... health , circumstances the sperm was collected or why the individual research was conducted . I checked the research Meta-analysis and the limitations are detailed as follows ....

Limitations ....
There are several possible limitations to this systematic review and meta-regression analysis. It is possible that failure to include non-English publications may have limited our analyses of non-Western countries. It has been claimed that men who are willing to provide semen sample may differ from the rest of the population leading to potential selection bias, but current evidence does not support this claim (Cooper et al., 2010).

We analyzed sperm counts (both by SC and TSC) but not sperm motility and morphology because information regarding motility and morphology were seldom available in older studies. Moreover, the recommended methods and criteria for motility and morphology assessments have changed significantly over time making across-time comparisons difficult. In contrast, the assessment of SC by hemocytometer, first described in 1902 (Benedict, 1902), has been the method recommended by the World Health Organization since 1980 (World Health Organization, 2010), and there is no evidence that this method has varied systematically over time. For these reasons SC is considered to be the most reliable endpoint for epidemiological analysis (Le Moal et al., 2016). Because of this stability and the variability of other counting methods over time we only included studies in which counting was done (or likely done) by hemocytometer and excluded studies that used alternative counting chambers (e.g. Makler, Coulter and Microcell) or non-manual methods (i.e. computer assisted sperm analysis or flow cytometry). Even though we followed detailed protocol, this study was not preregistered in Prospero.

Analysing trends by birth cohorts instead of year of sample collection may aid in assessing the causes of the decline (prenatal or in adult life) but was not feasible owing to lack of information.

If she conducted ACTUAL research (a longitudinal study ) and provided sample and research methodology then I might be more inclined to believe ( based on findings of course)

Ooooh Noooooo!!!
Zero population growth.

Maybe then I'll be able to put my boat in the water with out having to wait an hour and a half at the launch site.

Plus more cheetos for me.

The Institute for Population Research came out with a report similar to this years ago, though it wasn’t just about male fertility, it was about the future viability of humans reproducing in general. And I definitely believe it. Our environment is getting more toxic every year. We’ve covered our civilization with endocrine disrupting chemicals, and we’ve polluted our food supply with GMO soy, glyphosates, and bovine estrogen. And I see for myself how many expecting mothers aren’t able to carry to term. Miscarriages are rampant. Add to that the epidemic of autism in western civilization. Most European countries have already been reporting losses in native population for years, though their numbers are being replaced by migrants.
According to the IPR, in order to achieve true zero population growth, every person needs to have “an heir and a spare”, which would mean four children per couple, because the expectation is that two of the children will not successfully reproduce.

You have such an apt for seeing the big picture Mo

It may be part of the conspiracy theories, but the rumours have been going round for quite some time that the so called New World Order has planned for this and wants this.
Not sure why to be honest.
Aren't these people whining about an overpopulated planet? which is total BS btw.

In essence we could face similar problems with everything on the planet, including plants, insects and animals not being able to reproduce anymore due to the GM seeds that were also deliberately sold. These have 'infected' normal trees and plants as well.
I happened to be talking about this yesterday with my daughter. She brought it up.
It is quite worrying in one sense, in another nature does always restore itself, PROVIDED we stop messing with it.
I refuse to believe that it is too late yet.

No, no, no. My pick is Jason Mamoa....for his superb acting skills of course. 🤭🤭

The human body is unable to digest certain foods
as they are.

Soy gets turned into estrogen, so that it can be
digested.

For those unfamiliar with estrogen, it is a
female hormone. Therefore, probably not the best
thing in the world, to maintain a healthy sperm count.

Soy, is found in almost all processed foods.

I just watched the Australian fictional movie '2065', it is on Netflix. It is about last of humankind and trees etc. It is worth a watch...

Interesting Rock. Guess we better start freezing the little racers....

Know your body, and know what you're putting in it.

True. I am post menopause, so not really a worry for me. TMI? Lol, but it is life ...

There are foods and supplements, that convert to
testosterone... Could throw a woman's body out
of harmony with itself.

Hi there Ladywind. Call me 'naive' or whatever?
In all honesty, I have never considered nor have been remotely curious about your subject post.
How true it is, must be a concern.
You know, my simplistic view on this, was that Western societies 'plan' ahead and limit their family numbers and offsprings to affordability, with the expectation of a 'better life' for those who follow.
Not sure about the science. But might be accurate just the same.

I think this could certainly be...............being a late bloomer in the daddy department I know my "little racers" still worked 16 years ago when I was 48.

thanks!

Yep... I remember when I was a li'l girlie hearing a conversation between my mom and the farm woman who sold us eggs. She had a couple of daughters.
She told my mom that "These days there's hormones in chicken food and everything. My girls are getting hairs on their chins and breasts because of it!"
Now that was around 1972 and that woman wasn't the sharpest tool in the shed, but she did know that!

Meaning our food has been saturated with hormones and antibiotics for at least 50 years! That's a damned long time!

Another thing that might be of interest in this...
Apparently many ED stem from sitting to much, the muscles weakening. When sitting a lot, the testicles maybe also are warmer than they should be?

After all the reason they're outside of the body is that they require a slightly lower temp than body temp to function properly. When sitting all day long for work, and again at home...
It might be a contributing factor.

PS we need a test group with those Aussie PUB pants that can hold a cool inlay to see if that brings about change

I am inclined to agree with you. I was shocked to read the article, like surely something so important would be thoroughly researched before making these claims. It is only 20 years in the future!!!
I do believe it is a future possibility, but way into the future.... Not so soon.

Any chance of a link to that report? What year was that report?
