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%.
Ha! {wipes off mouse}
The Russians have won. They have made the world a cesspool of distrust, greed, fear and hate.
No...Blame the food. Whenever I go to those so called 3rd world countries, their fruits taste better, have an aroma and someone can tell that a neighbor is preparing beef or poultry from the perceived smell.
When one visits the fruit section of some of these so called healthy food stores, not an iota of smell/scent of fruit is perceived! Something is surely wrong here.
Heck, my wife gets pregnant if I look at her too long.
I don't think so. You might want to get a paternity test done on "your" kids.
The communist plot to dilute our precious bodily fluids has succeeded !
Not being able to belch and fart in public, no more wolf-whistling or swearing like a sailor, the cancellation of the Man Show, eating fscking gluten-free vegan yoghurt steak-substitute, and having to get in touch with our "feelings", not only are sperm counts heading for zero, at this rate we're going to start having periods.
Exactly what I was going to post
Fat = more estrogen = less sperm
Not to mention the other parts of our diet.
Try the massive contamination of drinking water with estrogen from birth control pills as well as the estrogen mimickers such as soy products.
Every time Mr. Skinny Jeans gets a soy Cappuccino along with his Tofu smoothie, goodbye a little of the Mr. and hello a little more of the Ms.
I'm all for reproductive rights, but if you even mention the possibility that all those birth control pills are screwing up the hormonal balance of literally everything that uses water, at least in the U.S., holey moley, the feminists will scream bloody murder.
Repeat after me: "Nothing, nothing on Earth matters more than MY reproductive rights!! Not my health, not your health, not the frogs and fishes health. NOTHING!!!"

Peace is easy to achieve, just surrender. Liberty is much harder get/keep.
I don't know. I'm no where near overweight (around 15% BF) and my wife and I are having some trouble with conceiving, so I got my sperm levels checked and they are quite low. Oddly my T-levels are on the high side of normal. I'm fit and run 30-40 miles per week. No grey hair and no guy at all.
145lbs and 37 years old.
You're probably too skinny. Too low a body weight also lowers sperm production.
A man's fertility may be affected by his weight, a new study shows. Men who are either too fat or too thin may find that they have lower sperm counts, often low enough to be classed as 'impaired fertility'. The study, undertaken by researchers in Denmark and published in the journal Fertility and Sterility, could lend weight to the possibility that high levels of obesity in Western societies may be contributing to fertility problems.
The researchers studied 1558 Danish men, comparing their sperm count to their body mass index (BMI - a measure of weight in relation to height). They found that men with either a low or a high BMI had differences in reproductive hormone levels as well as lower sperm counts than men of the recommended weight. Men with a low BMI (below 20) were, on average, found to have a 28 per cent lower sperm count and a 36 per cent lower sperm concentration than men with a normal BMI. Men with a high BMI (above 25) had a 22 per cent lower sperm count and 24 per cent lower sperm concentrations.
So if you're already borderline, all that running will make it worse. Same as too high a level of testosterone will.
Also, what do you mean by "no guy at all?"
"Transparent" is a shit show that trades on every stereotype going. A man in drag is NOT a transsexual.
I blame skinny jeans. I've been in boxers and loose pants for decades and have no issues. I see these young beta males running around in skin tight jeans and I just figure they never want kids or something.
It is likely the packaging too, look at plastics that leech BPA, which mimics estrogen.
Not sure if that is the cause, but the issue you describe is related to the fact that most fruits and vegetables these days are grown far away, and to save money on refrigeration, the fruit is picked green and allowed to ripen in transit. The downside is that the chemical processes are not the same as ripening on the tree/vine/etc. and you wind up with highly acidic produce lacking in some nutrients.
If you disagree, please post your argument. (-1, Overrated) isn't your personal censorship tool for views you don't like
A combination of obesity in men (besides not being able to spell) and the most highly educated women, those in academia, hating men
When did "women won't have sex with me" turn into "women hate all men".
Most of the women in academia that I know personally are in relationships. Bit of an odd claim that they hate men.
SJW n. One who posts facts.
Also, what do you mean by "no guy at all?"
Possibly you have identified the root cause of the lack of sperm count.
