Does Reishi Mushroom Increase Testosterone Levels? Exploring the Potential Effects

As society continues to grapple with the consequences of fast-paced living and aging, interest in natural health-boosting solutions has seen an upward trend. One such solution, the reishi mushroom, is a traditional medicinal staple attracting modern science’s attention. A common question people often ask is, ‘does reishi mushroom increase testosterone levels?’ In this article, we delve into the biology of testosterone, understand what reishi mushrooms are, and evaluate existing scientific literature to answer this question. We will also explore other factors influencing testosterone levels and discuss important considerations and precautions for using reishi mushrooms. 

Testosterone and its Role in the Body

Testosterone, a primary sex hormone in males, plays a critical role in the body. It’s responsible for the development of male reproductive tissues, including the testes and prostate, and promotes secondary sexual characteristics like muscle and bone mass growth and body hair. In addition, testosterone influences mood, energy levels, and cognitive function. Though naturally occurring in both men and women, men have about seven to eight times more testosterone than women. Yet, testosterone levels can fluctuate due to age, stress, and other lifestyle factors. Thus, ways to naturally increase testosterone levels, such as using reishi mushrooms, have gained significant attention.

Understanding Reishi Mushroom

Reishi Mushroom: An Overview

Reishi mushrooms, known scientifically as Ganoderma lucidum, are a type of fungus widely recognized for their potential health benefits. Originating from Asia, these mushrooms are often used in traditional medicine for their immune-boosting, anti-cancer, and longevity properties.

Potential Mechanisms of Action

Although the exact mechanisms are not fully understood, reishi mushrooms may boost testosterone levels by inhibiting the conversion of testosterone into estrogen, a process known as aromatization. They’re also thought to improve the body’s response to stress, which can positively impact testosterone production, as chronic stress can inhibit hormone production and disrupt hormonal balance.

Health Benefits of Reishi Mushrooms

Reishi mushrooms, a cornerstone of traditional Asian medicine, offer a myriad of health benefits supported by modern scientific research. Here are some of the key health benefits:

  1. Immune System Support: Renowned for their ability to bolster the immune system, reishi mushrooms carry beta-glucans. These polysaccharides have the potential to amplify the immune system’s efficiency by provoking immune cell activity and proliferation.
  2. Anti-Cancer Properties: Some studies suggest reishi mushrooms may have cancer-fighting properties due to their antioxidant capacity and ability to boost immune function. They may inhibit tumor growth and spread, especially in breast and prostate cancers.
  3. Heart Health: Reishi mushrooms may improve heart health by reducing blood pressure and cholesterol levels, mitigating key risk factors for heart disease.
  4. Stress and Fatigue Relief: As an adaptogen, reishi may help the body handle stress better. It’s often used to combat fatigue and depression, improving overall well-being.
  5. Liver Function: Reishi mushrooms may protect the liver and promote detoxification, enhancing the body’s ability to filter toxins.
  6. Blood Sugar Control: Some research suggests reishi mushrooms can help manage diabetes by reducing blood sugar levels.

It’s important to note that while reishi mushrooms present promising health benefits, more research is needed, especially in humans, to establish these effects fully. Always consult a healthcare provider before beginning any new supplement regimen.

Does Reishi Affect Hormones?

Reishi mushrooms, scientifically known as Ganoderma lucidum, have been recognized for their potential influence on hormones. Their use in traditional medicine dates back centuries, particularly in Asian cultures, for various health-related conditions.

Research has suggested that reishi mushrooms modulate the body’s hormonal system, but the exact mechanisms through which they do so remain unclear. It’s thought that reishi may affect hormonal balance by inhibiting the activity of an enzyme known as aromatase, which converts testosterone into estrogen. This could lead to increased levels of testosterone and decreased estrogen levels, although more research is needed to confirm these effects.

In addition to testosterone, reishi mushrooms may affect other stress-related hormones and immune function. They have been found to exhibit adaptogenic properties, helping the body maintain balance and resist the effects of stress. This could potentially influence cortisol levels, the body’s primary stress hormone, and other hormones associated with the body’s stress response.

However, although these effects are promising, much of the research has been conducted in animals or in vitro. Human studies are limited, and the results have been inconsistent. Thus, while reishi mushrooms may potentially affect hormones, further research is necessary to understand these effects fully and determine their clinical relevance. As always, before starting any new supplement regimen, it’s recommended to consult with a healthcare provider.

Research on Reishi Mushroom and Testosterone

Animal Studies

Research in animal models suggests that reishi mushrooms might impact testosterone levels. In one study, male mice given reishi mushroom extract showed a significant increase in serum testosterone levels compared to the control group. Still, while these findings are promising, they must be interpreted cautiously. The effects observed in animal studies do not always translate directly to humans due to physiological differences between species.

Human Studies

The research on reishi mushrooms and testosterone in humans is currently limited and inconsistent. Some small-scale studies suggest that reishi may improve symptoms related to low testosterone, such as fatigue and decreased sexual drive. However, these studies often have limitations, including small sample sizes and a lack of control groups. More comprehensive, well-designed studies are needed to confirm whether reishi mushrooms can effectively increase testosterone levels in humans.

Other Factors Influencing Testosterone Levels

While reishi mushrooms may potentially increase testosterone levels, it’s important to note that other factors can also influence testosterone production. Diet, exercise, sleep quality, and stress management all play crucial roles in maintaining optimal hormone balance. For example, foods high in zinc, vitamin D, and healthy fats have been associated with increased testosterone levels. Regular exercise, especially resistance and high-intensity interval training, can stimulate testosterone production.

Considerations and Precautions

Despite the potential benefits of reishi mushrooms testosterone, certain considerations should be made before incorporating them into your routine. Some people may experience side effects such as digestive upset, dry mouth, and allergic reactions. Additionally, reishi mushrooms may interact with certain medications, including blood thinners and immunosuppressants.

Pregnant and breastfeeding women, individuals with bleeding disorders, and those scheduled for surgery should avoid reishi mushroom testosterone. Also, those with autoimmune diseases should use reishi with caution, as it can stimulate the immune system.


In conclusion, even though some studies showed positive results in investigating the concept of reishi testosterone, the current research needs to be more definitive to make strong conclusions. Therefore, if you are considering using reishi mushrooms to boost testosterone levels, it’s important to consult with a healthcare provider to understand potential benefits, risks, and interactions. It’s also crucial to consider other lifestyle factors influencing testosterone production, including diet, exercise, and stress management.
