Does Drinking From Plastic Bottles Lower Testosterone?


In today’s modern world, plastic bottles have become a common sight. We use them for everything from carrying water to storing our favorite beverages. However, concerns have been raised about the potential impact of plastic bottles on our health, particularly on hormone levels. One hormone that has garnered attention is testosterone, the primary male sex hormone. In this article, we will explore the question: Does drinking from plastic bottles lower testosterone? Let’s delve into this topic and separate fact from fiction.

Understanding Testosterone:

Before we dive into the potential effects of plastic bottles on testosterone levels, it’s essential to understand the role testosterone plays in the human body. Testosterone is a hormone primarily produced in the testes of males and, to a lesser extent, in the ovaries of females. It is responsible for the development of male secondary sexual characteristics, such as muscle mass, facial hair, and deepening of the voice. Testosterone also plays a crucial role in overall health, including bone density, mood regulation, and libido.

The Concerns with Plastic Bottles:

Plastic bottles are typically made from a type of plastic known as polyethylene terephthalate (PET). This material is lightweight, durable, and widely used for packaging beverages. However, concerns arise when these bottles come into contact with liquids, especially when exposed to heat or prolonged use.

1. Leaching of Chemicals:

One of the primary concerns associated with plastic bottles is the potential leaching of chemicals into the liquids they contain. Studies have shown that certain chemicals, such as bisphenol A (BPA) and phthalates, can leach from plastic bottles into the beverages they store. BPA is a well-known endocrine disruptor, meaning it can interfere with hormone function in the body. Phthalates, on the other hand, are a group of chemicals used to soften plastics and increase their flexibility.

2. Hormonal Disruption:

The leaching of BPA and phthalates from plastic bottles has raised concerns about their potential impact on hormone levels, including testosterone. Animal studies have demonstrated that exposure to these chemicals can lead to hormonal disruptions and adverse effects on reproductive health. However, the direct translation of these findings to humans is still a topic of debate among researchers.

The Link Between Plastic Bottles and Testosterone:

While the concerns surrounding plastic bottles and their potential impact on testosterone are valid, the scientific evidence in humans remains limited. Several studies have investigated this topic, but the results have been inconsistent. Let’s explore the available evidence:

1. Human Studies:

A study published in the journal Environmental Health Perspectives examined the association between urinary BPA levels and reproductive hormones in men. The researchers found no significant correlation between BPA exposure and testosterone levels. However, they did find a weak association between BPA exposure and lower levels of sex hormone-binding globulin (SHBG), a protein that binds to testosterone and regulates its availability.

Another study published in the Journal of Clinical Endocrinology and Metabolism investigated the relationship between urinary phthalate metabolite concentrations and reproductive hormones in men. The researchers found no significant association between phthalate exposure and testosterone levels.

2. Limitations of Human Studies:

It’s important to note that human studies in this area have several limitations. Firstly, measuring exposure to chemicals like BPA and phthalates accurately is challenging, as these compounds metabolize quickly in the body. Additionally, assessing the long-term effects of plastic bottle usage on hormone levels requires extensive research over an extended period.


To address common questions and concerns about the potential link between plastic bottles and testosterone, we have compiled a list of frequently asked questions:

1. Are all plastic bottles made from the same material?

No, plastic bottles can be made from various materials. The most common plastic used for beverage bottles is polyethylene terephthalate (PET). However, other plastics, such as high-density polyethylene (HDPE) and polypropylene (PP), are also used.

2. Does the type of plastic affect the leaching of chemicals?

Yes, different types of plastics have varying degrees of chemical leaching. PET bottles, for example, have been shown to release small amounts of chemicals like BPA and phthalates when exposed to heat or extended use.

3. Is it safe to drink from plastic bottles?

The safety of drinking from plastic bottles depends on multiple factors, including the type of plastic, the duration of use, and the temperature of the beverage. It is generally recommended to use BPA-free bottles and avoid exposing them to high temperatures.

4. Can plastic bottles affect testosterone levels in women?

While most studies focus on the effects of plastic bottles on testosterone levels in men, it’s important to note that women can also be affected. Hormonal disruptions caused by chemicals leaching from plastic bottles may impact reproductive health in both males and females.


The question of whether drinking from plastic bottles lowers testosterone remains inconclusive. While animal studies suggest a potential link between chemical leaching from plastic bottles and hormonal disruptions, human studies have not provided strong evidence to support this claim. However, it is crucial to consider the limitations of existing research and the potential health risks associated with certain chemicals found in plastic bottles. To minimize potential exposure, using BPA-free bottles and avoiding prolonged exposure to heat is recommended. As scientific understanding continues to evolve, it is essential to stay informed and make informed choices regarding our health and well-being.
