Der durchschnittliche Testosteronspiegel von Männern hat sich in den letzten 50 Jahren halbiert, sagen Wissenschaftler. Forscher warnen vor einer „großen Krise der männlichen Fortpflanzungsgesundheit“, die teilweise auf Fettleibigkeit und Diabetes zurückzuführen ist.

Men’s average testosterone levels have halved over the past 50 years, according to scientists, who say society is facing a male fertility crisis.
Total testosterone levels in men declined by 54% between 1972 and 2019, according to data presented at the annual meeting of the European Society of Human Reproduction and Embryology in London on Tuesday.
Rising levels of obesity and diabetes are expected to play a part, but the team behind the work suggest that environmental factors such as endocrine-disrupting chemicals – which can be found in various household items – and global heating could also be factors in the apparent striking decline.
A fertility crisis is hardly a problem when people deliberately opt out of having kids.
Not to say that dropping testosterone levels isn’t a problem, but not for that reason.
PFAs are released in almost everything that’s manufactured. That ‘new’ car/house/furniture smell is just endocrine-disrupting chemicals.
Its also microplastics
no joke, google it
Ya
Dunno. With 9 billion people on Earth going on 10 billion that may be a good thing.
So, what am I doing right, then? I’m part of this group, probably have whatever levels the rest do. But I managed not to get fat, and I’ve avoided diabetes so far.
This has always seemed weird to me; I have to take HRT to get my t levels below 800.
Now let’s see what the future will look like with all the young kids shooting up steroids and peptides
Not peer reviewed.
But interesting nonetheless. Probably microplastics and obesity.
Ok well it’s time to get serious. Move to a farm, grow your own vegetables, adhere to an ivermectin and raw milk regimen, swim in sewage, stop getting vaccinated, don’t take Tylenol or antidepressants and stop drinking birth control pill and abortion water!
Give it a few years. With all the arsenic, mercury, parasites and pfas that these data centers are spewing out… and all the clean water/air regulations thrown to the curb…
Given gen z men went for Trump, guessing he just appeals to low testosterone men.
No wonder he loves ymca.
(/s that’s a myth btw, gay men have = T)
it’s all the sugar in our preserved food
The drop off started a few decades before Americans started getting obese though, this title is a bit misleading. The main cause is most likely environmental toxins, specifically groundwater and soil pollutants.
There is a large chunk of the US male population that look at eating vegetables and fruit as being not masculine. Some of this is self inflicted
LifeProTip: meat is often high in fat, and not necessarily a good source of protein. Nutritionists consider a hard-boiled egg to the gold standard protein source, as it contains a complete set of amino acids and is relatively low in fat. Other sources or protein that are better sources of protein (per calorie) than your typical cuts of meat include nuts, legumes, seeds, [quinoa](https://www.health.harvard.edu/heart-health/seed-of-the-month-quinoa), spinach, etc.
[Most of us eat too much meat, and it’s harming our health](https://www.mayoclinic.org/healthy-lifestyle/nutrition-and-healthy-eating/in-depth/meatless-meals/art-20048193).
Diabetes is not good for blood flow, either.

No surprise. They infiltrated the bulk of our processed food with soybean oil. Intentionally.
NIH and the American Diabetes Association define normal fasting glucose level as 70 –
99 mg/dL But some research shows that Testosterone levels start dropping well before that 99 number.
In a 2012 study of 400 Korean men in their 40s and 50s:
>
Total testosterone was significantly decreased in non-diabetic subjects with high-normal glucose and IFG levels. In particular, subjects in the high FPG groups (above 88 mg/dL) showed decreased testosterone levels after adjusting for age, BMI, smoking, and alcohol consumption

I can tell you from personal experience as a 55 year old man, I had ED problems for a couple years when my fasting glucose was in the upper 90s. Two months of low carb diet got that number into the 80s and the problems stopped immediately. I was never diagnosed as Diabetic or Pre-Diabetic. The problems start earlier than most people realize.
I think one thing to consider is the total cumulative exposure we now have to synthetic fragrance. It has skyrocketed in the last few decades. Think about the total number of fragrances we get hit with a day – laundry detergents, scent beads, plug ins, soaps. Colognes, hair stuff, cleaning supplies. It’s on your clothes, your sheets, towels, skin, hair, the air you breathe. All day and all night. You can’t go anywhere without get it. At low doses I’m sure the stuff is fine. But I doubt anyone has ever tested the types of exposures people get every day.
I plotted the use of fragrance and make T levels over time. I can’t share it here, but the inverse correlation is nearly perfect. Obviously correlation does not equal causation, but it sure should give us a reason to look at it.
Sorry, but can we stop linking The Guardian and link the actual study?
