Does Spearmint Lower Testosterone?

Spearmint is renowned for its numerous health benefits, notably its ability to help balance hormones in the body. Of particular significance is its influence on testosterone, a hormone of great importance.

This article offers a detailed look into how Spearmint may lower testosterone levels and the related mechanisms for readers to explore.

Does Spearmint Lower Testosterone?

Numerous research studies, ranging from animal models to human trials, consistently indicate a reduction in testosterone levels with the consumption of Spearmint.

For instance, a notable study involved mature male mice who were given spearmint tea at concentrations of 20-40g/l for 15 to 35 days, significantly decreasing their serum testosterone levels [1].

In another study, 21 female patients with hirsutism, including 12 with polycystic ovary syndrome (PCOS), were examined.

These participants consumed 250ml herbal tea made from 5g of dried Spearmint twice daily for 5 days during their menstrual cycle's follicular phase.

The trial demonstrated a significant decrease in free testosterone levels, though the overall testosterone levels remained unchanged [2].

These studies shed light on Spearmint's potential to impact hormone levels, particularly in lowering testosterone levels across various biological contexts.

How Does Spearmint Impact Androgen Levels?

With Females

For a long time, Spearmint has been demonstrated to possess anti-androgenic properties, which are particularly beneficial for female patients suffering from hirsutism due to polycystic ovary syndrome (PCOS).

PCOS is recognized as an endocrine disorder characterized by abnormally increased levels of androgens and oxidative stress.

This condition often results in several external manifestations, including obesity, irregular menstrual cycles, insulin resistance, oligomenorrhea, or anovulation.

Studies have highlighted Spearmint's ability to mitigate these symptoms by reducing androgen production and testosterone levels in the body.

Moreover, the Spearmint benefits for PCOS include its ability to boost antioxidant activity, which plays a vital role in reducing oxidative stress linked to the condition.

Notably, research findings suggest that spearmint consumption can restore ovarian growth and stimulate ovulation, offering a natural remedy to aid patients with PCOS in managing their symptoms and enhancing their reproductive health [4].

With Males

In the context of males, the potential benefits and implications of Spearmint's influence on testosterone and overall androgen levels remain ambiguous due to a lack of direct human studies.

However, insights can be gleaned from related research utilizing male animal models.

In correlated research involving a male mouse model, notable decreases in testosterone levels were noted due to the release of Follicle Stimulating Hormone (FSH) and Luteinizing Hormone (LH) from the lower pituitary region of the pituitary gland:

LH is critical in stimulating Leydig cells found in the testes' interstitial tissue to produce and secrete testosterone [3].

Meanwhile, FSH enhances the functionality of Sertoli cells, which act as intermediaries in the action of testosterone [3].

These findings suggest a complex interaction between Spearmint, pituitary hormone release, and testosterone synthesis and secretion in males.

Although these results provide a foundation for understanding Spearmint's potential impact on male hormonal levels, further research in human subjects is necessary to fully comprehend the implications of spearmint consumption on male endocrine health.

How Much Spearmint to Lower Testosterone?

Determining the precise amount of spearmint tea required to impact testosterone levels remains a subject of ongoing research due to the absence of standardized dosage guidelines.

Nevertheless, insights from current studies offer a tentative framework for individuals interested in using Spearmint to maintain hormonal balance.

For women, especially those with conditions related to high testosterone levels like hirsutism, a daily intake of spearmint tea prepared with 40g/l has been suggested as beneficial [2].

In men, based on animal studies, concentrations of spearmint tea ranging from 20g/l to 40g/l have shown a significant decrease in testosterone levels [1].

While these findings are promising, it's important to note that individual responses may vary. It is advisable to approach such regimens cautiously and seek medical guidance before making changes.

How Long Does It Take for Spearmint to Lower Testosterone?

The duration of noticeable effects varies between genders regarding Spearmint's impact on testosterone levels.

For women dealing with symptoms related to high testosterone, like hirsutism, a decrease in free testosterone was seen within five days of drinking spearmint tea twice daily (at a concentration of 40 g/l) [2].

This quick change highlights Spearmint's potential as a natural solution for female hormone balance.

On the other hand, the influence of Spearmint on male testosterone levels tends to unfold more gradually. A study on male mice revealed a reduction in testosterone starting around day 25, with the test lasting 15-35 days of consistent spearmint intake [1].

These findings indicate a slower adjustment in male testosterone levels compared to females.

Conclusion

Spearmint has demonstrated its efficacy in scientifically reducing testosterone levels, offering significant benefits, particularly for women managing PCOS-related hirsutism. However, men should exercise caution when using it, considering potential impacts on reproductive health.

To harness the advantages of Spearmint while mitigating adverse effects, maintaining a consistent dosage and incorporating appropriate breaks are vital strategies.

This comprehensive approach ensures the optimization of Spearmint's positive impact on hormonal health for both genders.
