In an era where health and wellness are at the forefront of public discourse, a silent crisis is emerging: men across different age brackets are experiencing a notable decline in testosterone levels, or low T. In this comprehensive guide, we delve into the reasons behind this worrisome trend, identifying key chemicals that are culprits in this decline.

Why is testosterone declining in men?

Testosterone, the quintessential male hormone, is pivotal for various bodily functions ranging from muscle mass and bone density to libido and mood regulation. Initially, it was believed that a drop in testosterone was primarily linked to aging. But now, comprehensive studies, including one led by Dr. Thomas Travison, are challenging this notion. Their research, involving over 1500 men from the Boston area, observed a striking decline in testosterone levels, averaging a 1% decrease per year since the 1980s. What's more startling is that this decline isn't just limited to older men; it's a cross-generational issue. A 65-year-old man in 2002, for instance, had significantly lower testosterone levels than a man of the same age in 1987. [1] [2]

While factors like obesity and smoking habits contribute to lower testosterone levels, they only explain a part of the story. The rapid rate of decline suggests the influence of other elements, possibly environmental. This hypothesis is gaining ground as we understand more about how lifestyle and environmental factors intersect with our hormonal health.

A study presented at the 2020 American Urological Association Virtual Experience revealed a consistent decrease in testosterone levels among adolescent and young adult men from 1999 to 2016. This data, gathered from over 4000 young men as part of the National Health and Nutrition Examination Surveys, showed a notable decline in average total testosterone levels, from 605.39 ng/dL in 1999–2000 to 451.22 ng/dL in 2015–2016. Even after accounting for variables like body mass index (BMI), the trend persisted. Surprisingly, this decrease was observed even in men with a normal BMI, contradicting the assumption that obesity alone is the culprit. [3] [4]

For young men, this trend is particularly alarming. Generally, testosterone levels in adolescent and young adult men are considered the standard for normal levels. If these are declining, it could lead to widespread under-treatment of testosterone deficiency, with far-reaching health consequences. Lower testosterone levels have been linked to an increased risk of health issues, including certain types of cancer, decreased libido, and erectile dysfunction.

What chemicals lower testosterone?

You might be surprised to learn that many everyday products contain chemicals that can mess with your hormone levels, particularly testosterone. These chemicals, known as endocrine-disrupting chemicals (EDCs), are found in various items we use daily. Let's break down some of these chemicals and see how they might be affecting your testosterone levels. [5]

DDT: A pesticide with long-lasting effects

Dichlorodiphenyltrichloroethane, or DDT, is a pesticide that hasn’t been used in the US since 1972 but still impacts us. Research has shown that in Florida, alligators exposed to DDT had 25% smaller sexual organs and 70% less testosterone than those in cleaner environments. For humans, a significant study involving 535 people found that higher DDT exposure led to noticeable changes in hormone levels, including testosterone. This shows that DDT's effects on our hormone health linger longer than we might expect.

BPA: It's everywhere and affecting you

Now, let's talk about bisphenol-A, or BPA. This chemical is found in many plastics, food packaging, and even in the receipts you get from stores. Interestingly, between 93% and 97% of people in the US have detectable levels of BPA in their urine. That's nearly everyone! BPA acts like estrogen and can interfere with male hormones. Workers exposed to BPA for over six months showed a significant decrease in testosterone levels and an increase in problems like erectile dysfunction and reduced sexual desire.

Phthalates: The ubiquitous chemical

Phthalates, which you'll find in plastic containers and personal care products, are in more than 75% of the US population's urine. That's a huge number! These chemicals can disrupt the way your body makes steroids and affect essential thyroid hormones. Though studies are mixed about their impact on things like erectile dysfunction, there's enough evidence to show they can negatively affect testosterone levels.

How do chemicals lower testosterone levels in men?

It's a bit like having a sneaky impostor in your system. Some chemicals, like BPA, are really good at pretending to be your body's natural hormones. This tricks your endocrine system, which is in charge of balancing your hormones. When these EDCs show up, they throw everything off balance, leading to lower testosterone production.

Imagine your body's hormone system as a busy highway, where hormones are the cars traveling to different parts of your body. Some chemicals act like roadblocks or misleading direction signs on this highway. For example, certain pesticides can latch onto hormone receptors, which are like the highway exits for hormones. When this happens, your hormones can't get to where they need to go, or they end up going the wrong way. This can lead to lower levels of testosterone because your body's normal hormone processes get all mixed up. [5]

How can I avoid exposure to chemicals that lower testosterone?

Reducing exposure to these chemicals is a vital step in safeguarding testosterone levels.

  • Avoiding plastics, especially those marked with recycling codes 3 (phthalates) and 7 (BPA), can significantly reduce exposure. Opt for glass or stainless steel alternatives for food and beverage storage.

  • Opting for organic produce can minimize exposure to harmful pesticides. Being mindful of the source and quality of meat and dairy products is also essential.

  • Beyond chemical avoidance, maintaining a healthy weight, engaging in regular physical activity, and maintaining a balanced diet are foundational steps in promoting healthy testosterone levels.

  • Regularly updating yourself on the latest research and recommendations regarding endocrine disruptors and opting for natural, non-toxic products for everyday use can make a substantial difference


The decline in testosterone levels among men is a multifaceted issue with profound implications. While aging plays a role, environmental chemicals significantly contribute to this trend. By understanding these factors and actively working to reduce exposure, we can take meaningful steps toward safeguarding our hormonal health.
