A growing body of research is shining a spotlight on so-called “superfoods”—such as honey, oysters, watermelon, ginger, and ginseng—for their potential benefits to male sexual health and fertility. According to a recent biochemical review published in the journal Current Research in Food Science, these foods may promote testosterone production, sperm quality, and erectile function, providing a natural alternative to pharmaceutical treatments and bringing renewed hope for men seeking to enhance their reproductive well-being (Physicians Weekly).
Interest in male sexual health and fertility is surging in Thailand and globally, reflecting concerns about the societal and personal impacts of declining fertility rates, stress-related sexual dysfunction, and the search for safe, effective remedies. In Thailand, demographic trends show a decrease in birth rates, mirrored by increasing reports of male infertility—an issue that can be deeply personal yet shapes community and national futures (World Bank). Many Thai men, influenced by local traditions and the popularity of alternative remedies, are eager for evidence-based natural solutions that align with cultural values emphasizing food as medicine.
The review, authored by researchers from Dhamar University and the University of Aleppo, surveyed the scientific literature on the active constituents and mechanisms by which these superfoods work. Traditional medical approaches in both Thailand and abroad typically rely on oral medications such as phosphodiesterase 5 inhibitors (PDE5i) for erectile dysfunction and fertility treatments. However, these pharmaceutical interventions, while effective in the short-term, carry potential adverse effects like cardiac arrhythmias, penile pain, or, in rare cases, the need for surgical intervention (Tandfonline). As many men seek alternatives presumed to be safer and more holistic, attention is turning to dietary and herbal options.
Leading the list of promising foods is honey, believed to support libido and sperm quality. The review points to research indicating that honey may raise circulating testosterone, stimulate hormones responsible for its production, and provide antioxidant protection for testicular tissue. Watermelon is highlighted for its role in boosting semen quality and reversing erectile dysfunction, attributed to its rich content of vitamins E and C, and citrus-derived phytochemicals like citrulline, which transforms into arginine. This precursor is required for synthesising nitric oxide—a molecule that dilates blood vessels and enhances blood flow to male reproductive organs.
Ginger, a staple in Thai cuisine and traditional remedies, is said to enhance libido and testosterone, as well as provide anti-inflammatory and antioxidant effects. It contains 6-gingerol, which helps stimulate nitric oxide production, again supporting vascular health in the male reproductive system.
Seafood, particularly oysters, stands out due to its high zinc content. Zinc is essential for testosterone synthesis and directly supports sperm formation and overall reproductive health; this aligns with the longstanding Thai tradition of consuming seafood as “tonic” food. Fish and fish oil are also mentioned for their vitamin A content, necessary for healthy sperm.
Ginseng, often featured in Southeast Asian tonics, has gained scientific support for its ability to modulate hormonal pathways linked to libido and stress, boosting sexual potency through the nitric oxide/cyclic guanosine monophosphate (cGMP) pathway. Nuts, especially walnuts, almonds, and hazelnuts, proved effective in improving sperm count, motility, and shape in randomized studies involving hundreds of participants (Urology Group). Omega-3 and omega-6 polyunsaturated fatty acids within nuts are seen as key contributors.
Probiotics, particularly strains of Lactobacillus plantarum, have shown promise in modulating the gut microbiome to impact endocrine pathways and boost testosterone, which in turn improves multiple markers of sperm health. A recent controlled trial observed infertile men supplementing with these probiotics experienced significant improvements in sperm motility, shape, and concentration versus placebo.
Avocados feature in the review for their rich vitamin E and zinc content—both believed to support testosterone creation and enhance sperm vitality. The phytonutrient composition in avocados may also promote sexual desire, a finding that appeals to many in regions where avocados are increasingly included in modern Thai diets.
An emerging scientific focus is on aromatase inhibitors. Aromatase is an enzyme that transforms testosterone into estrogen; by blocking this conversion, foods and extracts such as nettle root, maca, grape seed, and resveratrol may help preserve testosterone levels and improve several semen parameters. While pharmaceutical aromatase inhibitors are already in use for certain cases of male infertility, the research points to natural alternatives as potentially effective, though more clinical studies are needed.
The review’s authors advise caution alongside optimism. “Many men seek natural and nutritional remedies to enhance their sexual performance and reproductive health. These remedies are based on the consumption of aphrodisiac foods that have proven benefits for libido and fertility,” the researchers note, but stress that larger, longer-term clinical trials are essential for confirming benefits and determining optimal dosages and safety (Physicians Weekly). They recommend future studies not only clarify the biochemical mechanisms but also investigate synergistic actions between antioxidants, testosterone boosters, and aromatase inhibitors.
For Thai public health, these findings offer strategic direction. As noted by a Thai public hospital urologist, “Dietary approaches are culturally harmonious and affordable for most Thais. But it’s important for people not to self-medicate without professional advice, especially if they have chronic illnesses or take prescription drugs.” The Ministry of Public Health has already launched educational campaigns on healthy male sexual practices, and the new science around superfoods could inform updates to national dietary guidelines.
Interest in nutrient-dense foods is nothing new in Thailand. Historically, foods like honey, ginger, and nuts are mainstays in both Thai cuisine and folk remedies, long associated with energy and vitality. The current science, which bridges wisdom and evidence, could help elevate these traditions and remove stigma around male sexual health discussions—something public health advocates argue is long overdue.
Globally, trends in low birth rates and rising infertility are mirrored in Thailand. According to the World Health Organization, one in six couples worldwide experience infertility—a figure that has doubled in recent decades (WHO). Improvements in well-being through dietary patterns may not offer a cure-all but can contribute to holistic strategies for healthy living.
Thai experts underline the need for responsible dissemination of natural remedy information. Misuse or overreliance, they say, can delay proper diagnosis or treatment in cases of underlying disease. “We urge men to approach sexual health holistically—addressing diet, exercise, stress management, and medical consultation,” adds an academic from a leading Thai medical university.
Looking forward, collaboration between food scientists, medical researchers, and traditional health practitioners in Thailand may lead to innovative, culturally grounded interventions. There is also scope to develop local industries around superfoods, potentially benefiting farmers and entrepreneurs. However, ensuring consumer safety and clear public education will be vital.
For practical steps, Thai readers are encouraged to:
- Consult a qualified healthcare provider before making major dietary changes or seeking fertility solutions.
- Include a variety of foods—nuts, seafood, avocados, and traditional herbs like ginger—in a balanced diet.
- Avoid excessive use of supplements or herbal extracts without professional guidance.
- Engage in regular physical activity, avoid smoking and excess alcohol, and manage stress—all proven contributors to robust male sexual and reproductive health (Healthline).
- Stay informed about reputable scientific findings and beware of misleading advertising or miracle cure claims.
The evolving science of superfoods points to a future where food, health, and cultural knowledge blend seamlessly, supporting Thai men in living longer, healthier, and more fulfilling lives—with benefits that extend from individual families to the entire nation.
