Plastic products are known to contain endocrine-disrupting chemicals, such as phthalates and BPA, which can impact hormone levels, including testosterone. Studies have shown that exposure to these chemicals can lead to decreased testosterone levels, reduced sperm count, and even reproductive dysfunction in both humans and animals. While the impact of ingesting microplastics through drinking water on testosterone levels is still being researched, it is clear that the presence of plastics in our daily lives could be having a detrimental effect on our health. So, does drinking out of plastic kill testosterone? The answer is complex, but it is clear that the potential risks associated with plastic exposure are cause for concern.

Bisphenol-A (BPA) is an anti-androgen that blocks testosterone's normal effects
Bisphenol-A (BPA) is a synthetic estrogen that has been shown to have anti-androgenic effects, blocking testosterone's normal effects in the body. BPA is commonly found in plastic items such as food containers, water bottles, baby bottles, and even the lining of aluminium cans.
BPA exposure has been linked to a decrease in testosterone levels and an increase in reproductive issues in males. Studies have shown that exposure to BPA during the foetal life of mice resulted in reduced serum and testicular testosterone levels. Similarly, male mice exposed to BPA during the preimplantation period exhibited lower testosterone levels and altered androgen functions.
In humans, BPA exposure has been associated with male infertility and reproductive toxicity. The chemical compound has been found to impact the male reproductive system, affecting fertility and causing testosterone levels to decline.
BPA acts as an androgen receptor antagonist, preventing endogenous androgens from regulating androgen-dependent transcription and inhibiting cell proliferation. This mechanism involves blocking the amino- and carboxyl-terminal regions of androgen receptors and enhancing interactions with specific co-repressors.
The toxic effects of BPA exposure are not limited to testosterone levels and fertility. BPA has also been linked to possible cancers, insulin resistance, and cardiovascular problems. As a result, it is crucial to be aware of the potential risks associated with BPA exposure and take steps to minimise contact with this chemical, such as avoiding microwaving food in plastic containers.

Plastic softeners mimic oestrogen and can get into the body through inhalation, ingestion, or skin absorption
Plastic contains chemicals called endocrine disruptors, which can impact hormone levels, including testosterone. Endocrine disruptors mimic oestrogen and can enter the body through inhalation, ingestion, or skin absorption.
Phthalates are a type of endocrine disruptor commonly found in plastics. They are added to plastics to make them softer and more flexible. Products containing phthalates include shower curtains, shampoo, laundry detergent, and the coating on electrical wires. Research has shown that phthalates can inhibit testosterone production, reduce fertility, and damage sperm in humans. In animal studies, exposure to phthalates during fetal development decreased testosterone synthesis in male rats.
Bisphenol-A (BPA) is another endocrine disruptor found in plastics. It is an anti-androgen, meaning it blocks the normal effects of testosterone in the body. BPA can be found in food containers, baby bottles, water pipes, dental sealants, and even the lining of aluminium cans. Exposure to BPA has been linked to lower testosterone levels, reduced sperm count, and hampered sperm production.
In addition to phthalates and BPA, other endocrine disruptors to avoid include pesticides, POPs (persistent organic pollutants), and parabens. These chemicals can be found in everyday household items such as plastic bottles, furniture, and food containers.
The effects of endocrine disruptors on testosterone levels have been observed in both human and animal studies. In one study, middle-aged men and women with high levels of exposure to chemicals found in plastics had reduced testosterone levels. Another study examined the association between phthalate exposure and testosterone levels in 2,208 people and found that those with the highest levels of phthalates had the lowest testosterone levels.

Phthalates are chemicals added to plastics to make them softer and more flexible
Phthalates are derived from alcohols with 7-13 carbon atoms, which occupy a privileged position as general-purpose plasticizers, suitable for almost all flexible PVC applications. They are blended within the plastic article as a result of the manufacturing process and are not chemically bonded to the host plastics, so they can be released from the plastic article by relatively gentle means.
Phthalates are also used in personal-care items such as eye shadow, moisturizer, nail polish, liquid soap, and hair spray. They can be dermally absorbed and can also be inhaled, as they are found in many household items such as plastic bags, shower curtains, and vinyl flooring.
There are concerns about the health effects of phthalates, as they are endocrine disruptors that can impact hormone levels, including testosterone. Studies have shown that phthalates inhibit testosterone production in animals and reduce fertility by damaging sperm in humans. To avoid exposure to phthalates, it is recommended to eat a balanced diet, eliminate canned or packaged food, and refrain from using personal care products that contain phthalates.
It is important to note that phthalates do not accumulate in our bodies. They are quickly metabolized and removed from our bodies within hours, according to biomonitoring data. However, regulatory bodies are continuously evaluating the health and safety data of phthalates to ensure their suitability for specific uses.

BPA is found in food containers, baby bottles, and water pipes
Bisphenol-A, commonly known as BPA, is a chemical used in the production of polycarbonate plastics and epoxy resins. It is commonly found in food containers, baby bottles, and water pipes, as well as in other products like plastic water bottles, dental sealants, and canned foods.
BPA is an endocrine disruptor, meaning it can interfere with the body's hormones. In particular, BPA blocks the effects of testosterone, lowers sperm count, and hampers sperm production. Studies have shown that BPA exposure is linked to lower testosterone levels and other health issues, such as infertility, insulin resistance, and cardiovascular problems. Due to these concerns, many people opt for products labeled "BPA-free."
However, it's important to note that even BPA-free products may not be completely safe. Alternatives like BPS and BPF, which are commonly found in "BPA-free" items, may still pose potential health risks. Therefore, it is recommended to limit exposure to BPA and similar chemicals as much as possible.
To reduce BPA exposure, it is advised to avoid canned foods and opt for fresh, whole foods instead. When purchasing packaged foods, choose products that are labeled "BPA-free" and avoid plastics with recycling codes 3 or 7. It is also recommended to use glass, porcelain, or stainless steel containers, especially for hot food or liquids, as heat can cause additional BPA to leach out.
By taking these precautions and being mindful of the potential risks associated with BPA exposure, individuals can make informed choices to protect their health and well-being.

A study found that mice exposed to polystyrene microplastics experienced reduced testosterone levels
While it is unclear if drinking out of plastic will kill testosterone, there is evidence that suggests exposure to certain chemicals found in plastics can lead to decreased testosterone levels. A study found that mice exposed to polystyrene microplastics experienced reduced testosterone levels.
Polystyrene microplastics, or PS-MPs, are tiny plastic particles that are difficult to degrade and can be easily ingested by small organisms, eventually making their way up the food chain. In the study, mice were given drinking water containing different sizes of PS-MPs for 180 days. The results showed that exposure to these microplastics led to reduced testosterone levels, altered testicular morphology, and decreased sperm viability and increased abnormality.
This study adds to a growing body of research indicating the potential harm of microplastics and other plastic-derived chemicals on reproductive health. For example, chemicals called endocrine disruptors, found in many plastic products, have been shown to impact hormone levels, including testosterone. Phthalates, a type of endocrine disruptor, have been linked to decreased testosterone levels, reduced sperm count, and damaged sperm in both animal studies and human observations. Bisphenol-A (BPA), another chemical found in plastics, acts as an anti-androgen, blocking the normal effects of testosterone and negatively impacting fertility.
While the specific mechanism by which PS-MPs decrease testosterone levels is still being investigated, the study's findings suggest that chronic exposure to these microplastics may induce male reproductive toxicity by interfering with the LH-mediated LHR/cAMP/PKA/StAR pathway, leading to reduced testosterone synthesis. This pathway is crucial for maintaining proper testosterone levels and reproductive function.
The implications of this research extend beyond the mice in the study, highlighting the potential risks associated with plastic usage and exposure to microplastics. While further studies are needed to fully understand the complex interactions between plastic chemicals and human health, these initial findings underscore the importance of reducing plastic consumption and seeking alternatives to plastic products, particularly for items that come into direct contact with food and beverages.
