Does Reishi Lower Testosterone? Exploring the Truth Behind the Claims


In recent years, the use of Reishi mushrooms as a natural health supplement has gained significant popularity. These mushrooms, scientifically known as Ganoderma lucidum, have a long history of traditional use in various cultures for their potential health benefits. However, a common concern among men is whether consuming Reishi can lower testosterone levels. In this article, we will delve into the scientific research and explore the truth behind these claims.

Understanding Testosterone:

Before we dive into the potential effects of Reishi on testosterone, let’s first understand what testosterone is and its role in the body. Testosterone is a hormone primarily found in males, although it is also present in smaller amounts in females. It plays a crucial role in regulating sexual function, muscle mass, bone density, and overall well-being. Any significant fluctuations in testosterone levels can have a profound impact on a person’s health.

The Claims:

Some sources suggest that Reishi mushrooms may have anti-androgenic properties, meaning they could potentially reduce the levels of testosterone in the body. This claim has understandably raised concerns among men, particularly those who rely on healthy testosterone levels for optimal physical performance and well-being. However, it is important to approach these claims with a critical mindset and examine the available scientific evidence.

Examining the Scientific Evidence:

To determine whether Reishi mushrooms can actually lower testosterone levels, we need to look at scientific studies conducted in this area. It is worth noting that research on the effects of Reishi on testosterone is limited, and most studies have been conducted on animals or in test tubes. Therefore, the findings may not directly translate to human physiology.

Animal Studies:

Several animal studies have been conducted to evaluate the impact of Reishi mushrooms on testosterone levels. One study published in the Journal of Ethnopharmacology found that male rats treated with Reishi extract experienced a decrease in testosterone levels compared to the control group. However, it is important to note that these studies were conducted on animals and may not necessarily reflect the effects on human testosterone levels.

Human Studies:

While there is limited research specifically focusing on Reishi mushrooms and testosterone levels in humans, a few studies have explored the overall effects of Reishi on hormonal balance and well-being. One study published in the journal Pharmacological Research examined the effects of Reishi extract on menopausal women. The researchers found that Reishi supplementation improved hormonal balance without negatively impacting testosterone levels.

Another study published in the International Journal of Medicinal Mushrooms investigated the effects of Reishi supplementation on men with prostate cancer. The results showed no significant changes in testosterone levels, suggesting that Reishi consumption may not have a negative impact on this hormone.


To address some common concerns and questions about Reishi mushrooms and testosterone, let’s dive into a FAQs section:

1. Can Reishi mushrooms lower testosterone levels in men?
– While some animal studies suggest a potential decrease in testosterone levels, there is limited scientific evidence to support this claim in humans.

2. Is it safe for men to consume Reishi mushrooms?
– Yes, Reishi mushrooms are generally considered safe for consumption. However, it is always advisable to consult with a healthcare professional before adding any new supplement to your routine.

3. Can Reishi mushrooms improve overall hormonal balance?
– Some studies suggest that Reishi mushrooms may have positive effects on hormonal balance, particularly in menopausal women. However, more research is needed to fully understand these effects.

4. Are there any potential side effects of Reishi mushroom consumption?
– Reishi mushrooms are generally safe for most people when consumed in appropriate amounts. However, some individuals may experience mild side effects such as upset stomach or allergic reactions. It is important to follow recommended dosages and consult a healthcare professional if any adverse reactions occur.

5. Can Reishi mushrooms enhance athletic performance?
– While Reishi mushrooms have been traditionally used for their potential health benefits, there is limited scientific evidence to support their role in enhancing athletic performance or testosterone levels.


Based on the available scientific evidence, it is inconclusive whether Reishi mushrooms can significantly lower testosterone levels in humans. While some animal studies suggest a potential decrease in testosterone, human studies have not found consistent evidence to support this claim. As with any supplement, it is always advisable to consult with a healthcare professional before incorporating Reishi mushrooms into your routine. Additionally, it is important to remember that individual responses to supplements may vary, and what works for one person may not necessarily work for another.
