Garlic and Testosterone: Does Garlic Raise Testosterone?

Several studies have explored the relationship between garlic consumption and testosterone levels. Garlic contains sulfur-containing organic compounds called allyl derivatives, including alliin, allicin, S-allyl cysteine, and diallyl disulfide. These compounds have been found to have potential testosterone-boosting effects [1]. However, there are a lot more studies around these compounds found in garlic that have been shwon to benefit symptoms of low testosterone.

There is also some evidence to suggest some garlic extracts can help with some causes of low testosterone such as reducing cortisol (the stress hormone) build up within the body. 

That all said, there is not a large body of evidence that garlic can raise testosterone levels in humans directly, with the only studies currently available being on mice. 

As a final note, there are some studies that have been done on other members of the garlic family (particularly onions), that have some minor links, although once again there isn't a huge body of evidence to support that onions can raise testosterone, although there is some minor evidence to suggest that it could be the case.

Garlics Effect On Low Testosterone Symptoms

Increased Blood Flow and Erectile Function

One of the key factors contributing to healthy testosterone levels is proper blood flow. Research suggests that garlic may help improve blood circulation, making it beneficial for conditions like erectile dysfunction (ED). Several human and animal studies have shown that compounds present in garlic can enhance blood flow and improve blood vessel function [2, 3, 4].

In a study conducted on older men, a medication containing aged garlic extract, ginseng, and velvet antler was found to improve erectile function [5]. Furthermore, garlic has been shown to increase nitric oxide levels, a compound that helps dilate blood vessels and promote better blood flow, potentially aiding in erectile function improvement [6, 7, 8].

While these findings suggest a positive impact of garlic on erectile function, more human studies are needed to fully understand the effects of garlic on this specific aspect.

Potential Enhancement of Male Fertility

In addition to its potential impact on blood flow, garlic has also been associated with improvements in male fertility. A review of 18 studies concluded that garlic supplementation could boost sperm production and increase testosterone levels, possibly due to its antioxidant properties [9].

Garlic's Potential Impact on Testosterone Production

In a recent animal study, a compound called S-allyl cysteine found in garlic was found to increase testosterone production in mice [10]. Additionally, aged garlic extract was shown to protect against chemotherapy-induced changes in sperm production and testosterone levels in another animal study [11].

There has also been studies on Allicin, one of the allyl derivatives found in garlic, has been the focus of much research. These studies suggest that allicin can increase energy levels and decrease cortisol levels, a stress hormone known to impact testosterone production. Additionally, it was found that garlic can suppress psychological stress by regulating cortisol levels and oxidative stress response in the brain. And as cortisol and stress directly lower testosterone this is a known mechanism for boosting test levels.

While these findings are promising, further research is needed to determine the precise mechanisms by which garlic affects male fertility and testosterone levels in humans.

Antioxidant Properties and Hormonal Balance

Garlic is known to possess potent antioxidant properties, which can protect against oxidative stress and damage. Antioxidants play a crucial role in maintaining overall health and well-being, including sexual health and fertility.

The antioxidants present in fresh garlic and aged garlic extract can help neutralize harmful compounds known as free radicals [12]. A study among men with infertility found that taking an antioxidant supplement increased sperm count [13]. Furthermore, an animal study demonstrated that S-allyl cysteine from garlic improved erectile function by blocking the formation of free radicals in rats with diabetes [14].

Although limited human studies have been conducted in this area, the antioxidant properties of garlic suggest potential benefits for sexual function and fertility.

Other Health Benefits of Garlic

Beyond its potential impact on testosterone levels, garlic offers a range of additional health benefits. These benefits contribute to overall well-being and may indirectly support hormonal health. Here are a few potential advantages of incorporating garlic into your diet:

Cardiovascular Health - Garlic has been associated with improved cardiovascular health, including reduced cholesterol levels and blood pressure. Healthy cardiovascular function is crucial for optimal hormonal balance. 

Antioxidant Properties - Garlic is rich in antioxidants, which help neutralize harmful compounds known as free radicals. Antioxidants play a vital role in protecting cells from damage and promoting overall health.

Anti-inflammatory Effects - Chronic inflammation can disrupt hormonal balance and contribute to various health issues. Garlic exhibits anti-inflammatory properties that may help reduce inflammation in the body.

Immune Support - Garlic has long been revered for its immune-boosting properties. A strong immune system is essential for maintaining overall health and hormonal balance.

While these benefits are not directly linked to testosterone production, they contribute to overall well-being and may indirectly support hormonal health.

Garlic Dose For Testosterone

Currently there is not enough information on garlic's impact on testosterone for there to be a recommended dose. 

Does Garlic Raise Testosterone? 

There's a reasonable amount of supporting evidence for there to be legitimate interest in the impacts of garlic and testosterone, although certainly not enough to make any substantial cliams. That said, garlic does have more than a few compounds that have shown it to be good for health in general. As a result, we certainly wouldn't say it's a complete myth with no substance, but there are plant compounds that have been far more well studied. 

While research suggests that garlic, particularly its bioactive compounds, may have a positive impact on testosterone levels, more studies are needed to fully understand the extent of this connection in humans.

Incorporating garlic into your diet, whether raw or cooked, can provide an array of potential health benefits that indirectly support hormonal balance. However, it is important to remember that maintaining overall well-being goes beyond a single ingredient or dietary component. It requires a holistic approach, including regular exercise, a balanced diet, adequate rest, and stress management.
