Does Drinking From Plastic Bottles Lower Testosterone?


In today’s fast-paced world, plastic bottles have become a convenient and common way to stay hydrated. Whether it’s during a workout, at the office, or on the go, many of us rely on these bottles to quench our thirst. However, concerns have been raised about the potential effects of drinking from plastic bottles on our health, particularly in relation to testosterone levels. In this article, we will explore the question: does drinking from plastic bottles lower testosterone?

Understanding Testosterone:

Before delving into the potential effects of plastic bottles on testosterone, let’s first understand what testosterone is and its role in the body. Testosterone is a hormone primarily produced in the testes in males and in smaller amounts in the ovaries and adrenal glands in females. It plays a crucial role in various bodily functions, including the development of male sexual characteristics, sperm production, muscle mass, bone density, and overall well-being.

1. The Concerns Surrounding Plastic Bottles:

Plastic bottles are typically made of polyethylene terephthalate (PET), a lightweight and durable plastic. However, concerns have been raised about the potential health risks associated with the chemicals found in plastic, particularly when it comes to hormones like testosterone. One such chemical is bisphenol A (BPA), which is used in the production of certain plastics and epoxy resins. BPA has been found to have estrogenic effects, meaning it can mimic the activity of the hormone estrogen in the body. This has led to concerns that BPA may disrupt the hormonal balance in both men and women.

2. The Effects of BPA on Testosterone Levels:

Numerous studies have investigated the effects of BPA on testosterone levels, with varying results. Some studies suggest that exposure to BPA may indeed lower testosterone levels. For example, a study published in the journal Environmental Health Perspectives found that men who had higher levels of BPA in their urine had lower total testosterone levels. Similarly, another study published in the Journal of Clinical Endocrinology & Metabolism reported that BPA exposure was associated with lower testosterone levels in men.

3. Other Chemicals in Plastic Bottles:

While BPA has received significant attention, it is important to note that there are other chemicals present in plastic bottles that may also have hormonal effects. These chemicals include phthalates, which are used to make plastics more flexible, and styrene, which is used in the production of polystyrene plastics. Like BPA, these chemicals have been found to have estrogenic effects and may disrupt the endocrine system.

4. Potential Impact on Male Fertility:

Testosterone plays a crucial role in male fertility, and any disruption to its levels can have implications for reproductive health. Some studies suggest that exposure to chemicals found in plastic bottles, including BPA and phthalates, may impact sperm quality and fertility in men. For example, a study published in the journal Fertility and Sterility found an association between BPA exposure and decreased sperm concentration and motility.

FAQs (Frequently Asked Questions):

Now, let’s address some commonly asked questions regarding the topic:

1. Can drinking from plastic bottles affect testosterone levels in women?

While most studies focus on the effects of plastic bottle chemicals on testosterone levels in men, it is possible that women may also be affected. However, more research is needed to fully understand the potential impact on female hormone levels.

2. Are all plastic bottles harmful?

Not all plastic bottles are created equal. Some manufacturers produce bottles that are labeled “BPA-free,” meaning they do not contain bisphenol A. These bottles are generally considered to be a safer option. However, it is important to note that they may still contain other chemicals, such as phthalates, that could have hormonal effects.

3. Are there any alternatives to plastic bottles?

Yes, there are several alternatives to plastic bottles. Stainless steel bottles, glass bottles, and reusable water containers made from other materials are widely available. These options can help reduce exposure to potentially harmful chemicals found in plastic bottles.

4. Can I still use plastic bottles if I’m concerned about testosterone levels?

If you’re concerned about the potential effects of plastic bottles on testosterone levels, you may consider reducing your use of plastic bottles or opting for BPA-free alternatives. Additionally, staying hydrated through other means, such as drinking from glass or stainless steel containers, can help alleviate any concerns.


While the question of whether drinking from plastic bottles lowers testosterone levels is still a topic of debate, there is evidence to suggest that certain chemicals found in plastic, such as BPA and phthalates, may have hormonal effects. These effects could potentially disrupt testosterone levels in both men and women. As more research is conducted, it is important to stay informed about the potential risks associated with plastic bottles and consider alternative options for staying hydrated. Ultimately, making conscious choices about the containers we use for drinking water can contribute to our overall well-being.
