This has been talked about for decades now. I just assumed it was common knowledge.

It's interesting to note here, its not just western caucasion men, but all men of all races seem to be facing something similar.

Micro plastics maybe?

AI Overview

While testosterone levels naturally decline with age in men, there's evidence suggesting a more widespread and potentially concerning decline in testosterone levels across all races, with the exact reasons still under investigation. Several factors are likely contributing, including age, obesity, chronic diseases, and lifestyle factors.

This article tries to play it off as if its just people being overweight and unhealthy that is causing it. Sure sure, it definitely isnt the cheap plastic and/or food preservatives/flavorings that are part of the problem. Nahhhh.

Many microplastics carry endocrine-disrupting chemicals (known as EDCs) such as phthalates and bisphenol A (BPA). These substances can mimic or interfere with the body’s natural hormones, causing health effects like reducing testosterone levels and altering hormonal balance over time. While the long-term impact of microplastic exposure is still under investigation, studies suggest a link between high levels of EDCS and reduced sperm quality, lower testosterone, and metabolic issues in men.

Think thats a concidence?

Processed foods, accounting for most consumable food categories today, contain considerable amounts of food additives. Food additives are substances added to food products to improve taste, consistency, appearance, or shelf life. Various food additives, such as phthalates, bisphenol A, tartrazine, erythrosine, artificial sweeteners, and parabens, have been identified as potential sources of endocrine-disrupting chemicals (EDCs) in processed foods. EDCs are substances that frequently interfere with the regular functioning of the endocrine system, creating an unusual environment in the biological system, which leads to adverse health effects such as the disruption of hormone synthesis, receptor binding, and signal transduction pathways, as well as energy metabolic homeostatic disorders which potentially increasing the risk of obesity, type-2 diabetes, cardiometabolic diseases and may also trigger allergic reactions. Consequently, they can also impact mammary gland development, and reproductive function, further leading to developmental abnormalities.

Remember there is no direct evidence that suggests this is even true. Also dont forget, always profit over people. /s

It literally gave the sources in the image… I have more, though.

It’s kept pretty quiet, but many white men are basically infertile now. Purposeful poison put into the food and water supplies have destroyed our healthy hormonal expression. We have, on average, less than half the testosterone of men just 80 years ago (HMM I WONDER WHY THAT WOULD BE THE CUTOFF). Our sperm basically don’t exist, nor does the expression of our psychology which led us to create the greatest civilization in the world. We do absolutely nothing whatsoever about the destruction of our homes, the corruption of our women, and the rape of our children, where historically we would have exterminated the jews down to the last unborn child for so much as daring to do this.

Meanwhile, the entirety of our society exists solely to destroy the psychological and social expression of traditional masculinity. The APA has declared “traditional masculinity” to be a mental illness. Male children are purposely prevented from behaving as men behave, which makes it impossible for them to comprehend how to raise a family in a non-jewish manner.

We’ve been psychologically and physically castrated. Even the people who know about this, like us, do absolutely nothing to stop it.

An average of 400-550ng/dl for healthy men in their prime is depressing. I'm in my 30's and recently got a result of 700. We live in peak soy times. I'm sure my grandad wouldn't be able to wrap his head around all the gender nonsense, feminism and "hate speech", let alone seriously engaging with this bs.

Yes, it has. This may have inflated measured T levels in the past. Still the decline trend of 1% per year can be established even if looking at the past decade or so.
