#Hormones

A new study in Psychoneuroendocrinology reveals that stress responses hinge on the balance between testosterone and cortisol, not on a single hormone alone. For Thai readers, this means stress management may depend on understanding internal biology as well as external pressures from school and work. The findings offer fresh perspectives for mental health strategies, schools, and workplace programs across Thailand’s diverse communities.

Historically, cortisol has been labeled the primary stress hormone, influencing energy, immunity, and the fight-or-flight response. Testosterone, while linked to reproductive health, also affects mood and social behavior. The study suggests that the interaction between these hormones shapes how stress is perceived and handled in social situations.

Revolutionary research published in Psychoneuroendocrinology unveils complex interactions between testosterone and cortisol that fundamentally reshape scientific understanding of how young men experience and manage stress in social situations. The groundbreaking study demonstrates that stress responses depend not on individual hormone levels but rather on delicate balances between testosterone and cortisol that determine whether challenging situations feel manageable or overwhelming. These discoveries hold particular promise for advancing mental health approaches, educational strategies, and stress management programs throughout Thailand, where demanding academic environments and workplace pressures create significant psychological challenges for male populations across diverse age groups and socioeconomic backgrounds.

A new study published in the journal Psychoneuroendocrinology has uncovered that young men’s reactions to stress may be shaped not just by levels of single hormones, but by the balance between testosterone and cortisol. This research marks a significant shift in our understanding of how the body and mind interact during stressful social situations—insights that may hold promise for future approaches to mental health, stress management, and even educational settings in Thailand and beyond.

A new study published in Psychoneuroendocrinology shows that men’s stress responses rely on the balance between two hormones, not just their individual levels. In young men, how stressed they feel depends on the interaction between testosterone and cortisol.

When cortisol is low, higher testosterone is linked to a reduced sense of stress. Conversely, high cortisol changes the effect of testosterone, offering little to no protection against stress. The findings add nuance to how we understand emotional health for men in Thailand and around the world.

A recent study published in the journal Psychoneuroendocrinology suggests that the way young men perceive and respond to social stress may be explained not by individual hormone levels alone, but by the dynamic balance between testosterone and cortisol. According to the research, high testosterone is linked to a lower perception of stress—but only when cortisol, the primary “stress hormone,” is low. Conversely, elevated cortisol appears to ease stress only in those with lower testosterone. This nuanced finding adds depth to our understanding of stress, with implications for emotional health and well-being among men in Thailand and globally (PsyPost).

A rising fitness craze fueled by social media is pushing many men in their 20s and 30s to try testosterone boosters. While the goal of stronger bodies and more energy is appealing, medical experts warn of real risks, including potential damage to fertility.

In gyms and online shops across Thailand, testosterone boosters range from herbal blends to injectable hormones. Aggressive marketing and influencer endorsements often promise quick gains, but doctors caution that the benefits may come at a steep personal cost. Self-prescribing and unsupervised use raise serious health concerns.

A new wave of fitness culture and social media influence has driven increasing numbers of men—including many in their 20s and 30s—to use testosterone supplements in pursuit of enhanced masculinity, muscle gain, and sexual vitality. However, recent research and expert warnings are raising red flags: these supplements, widely marketed as a path to becoming an ‘alpha male,’ can actually cause infertility, with potentially irreversible effects.

Across gyms and online platforms in Thailand and worldwide, testosterone boosters—ranging from herbal products to powerful hormone injections—are being promoted as quick solutions for increased strength, confidence, and libido. This market boom has been further fuelled by aggressive advertising, gym trainer recommendations, and the influence of fitness influencers online. Yet, experts are cautioning that the promised benefits may come at the cost of a man’s future ability to father children, and that misuse can have wider health implications (NDTV).

A new synthesis of 25 years of global research links certain hormonal patterns to psychopathic traits, offering fresh angles for early intervention among at-risk youths. The analysis suggests biology and behavior are more intertwined than once thought. In Thailand, where youth behavior and mental health are policy priorities, these findings could inform holistic prevention strategies that combine education, health services, and social support.

Across 26 studies, researchers examined hormones such as cortisol, testosterone, estradiol, oxytocin, and DHEA in adolescents and young adults. The most consistent finding is that higher resting cortisol levels—the body’s main stress hormone—are associated with impulsive and antisocial aspects of psychopathy, rather than emotional detachment alone. This nuance challenges older ideas and points to a dynamic link between biology and conduct.

A new meta-analysis has shed light on the complex links between hormonal activity and psychopathic tendencies, raising the prospect of more nuanced approaches to identifying and supporting at-risk youth. The study, published in Psychology & Neuroscience, draws on 25 years of worldwide research and upends some previous assumptions about the biology of personality disorders, with potential implications for prevention and mental health services in Thailand and beyond (psypost.org).

At its core, the research reviewed studies examining the role of endocrine system hormones—such as cortisol, testosterone, estradiol, oxytocin, and dehydroepiandrosterone (DHEA)—in the development of psychopathic traits, especially during the sensitive years of adolescence and early adulthood. The strongest and most consistent finding was a statistically significant association between higher baseline levels of cortisol—the body’s primary stress hormone—and the impulsive, antisocial dimension of psychopathy.

A growing number of women report a surprising menopause-related change: a sharpened sense of smell that can feel overwhelming. This evolving issue adds a new layer to the menopause experience, influencing daily routines, relationships, and mental wellbeing. Medical professionals note that research is still limited and women often lack clear guidance or support.

Menopause, the decline of reproductive hormones typically between ages 45 and 55, brings hot flashes, mood shifts, and sleep disruption. Thai women, like women worldwide, have long understood these symptoms as part of aging. Now, heightened olfactory sensitivity is emerging as a real concern for some, prompting doctors to seek better understandings and practical guidance.

A recently reported side effect of menopause—an acute and sometimes unbearable heightening of the sense of smell—has cast light on an under-recognised health issue affecting women globally, including in Thailand. While hot flashes, mood swings, and sleep problems are well-documented hallmarks of menopause, women are coming forward with distressing accounts of ordinary smells becoming intolerable, wreaking havoc on daily life and relationships. Medical professionals admit that the problem is little understood, and concrete solutions remain elusive, leaving many women without adequate support.

A wave of new research is overturning long-held beliefs about the ovary, showing it as more than just a reproductive organ. Scientists now argue that the ovary plays a central, underappreciated role in shaping women’s overall health and longevity, influencing everything from cardiovascular and bone health to brain function and life expectancy. As groundbreaking findings emerge, experts are calling for greater focus on this overlooked organ—a call that carries important implications for Thai women across the lifespan.

New research is changing how we view the ovary. No longer seen only as a reproductive organ, it is increasingly recognized as a driver of overall health and longevity. Experts say protecting ovarian health could influence cardiovascular, bone, brain health, and life expectancy—an insight with strong implications for Thai women as the population ages.

Historically, ovary discussions focused on fertility and menopause. Now, evidence highlighted in a national- and international-interest briefing shows the ovary ages faster than many other organs. Its decline can trigger changes across the body, elevating risks of heart disease, osteoporosis, dementia, and autoimmune conditions. As life expectancy climbs in Thailand, more women spend extended years after menopause, making ovarian health a public health priority.

A groundbreaking study published in Biological Psychiatry: Cognitive Neuroscience and Neuroimaging has revealed that testosterone significantly increases men’s sensitivity to social feedback, reshaping how they experience moment-to-moment self-esteem. The findings promise fresh insights for understanding self-worth, mental health, and social behavior, with potential implications for treatment approaches that resonate in Thai society and beyond (psypost.org).

A team of international scientists set out to unpack testosterone’s intricate role in influencing not just the overall sense of self-worth—what psychologists call “trait self-esteem”—but the more fleeting, variable feelings of self-value known as “state self-esteem.” The research matters deeply for Thai readers, as cultural norms around masculinity, social acceptance, and mental health coverage intersect with emerging scientific understanding, and because mental health struggles linked to low self-esteem, especially among young men, are increasingly noted across Thailand (WHO).

A new study in Biological Psychiatry: Cognitive Neuroscience and Neuroimaging shows that testosterone makes young men more responsive to social feedback. Positive reactions boost self-esteem more, while negative feedback causes sharper declines. The research highlights how biology and social context interact to shape mood and behavior, with potential relevance for mental health strategies in Thailand.

Researchers recruited 120 healthy men aged 18–26 in a double-blind, placebo-controlled trial. After applying testosterone gel or a placebo, participants waited to reach peak hormone levels and then completed a realistic social-evaluation task. They crafted profiles that 184 supposed strangers would review, receiving a mix of approval, disapproval, and neutral feedback. In reality, feedback was pre-programmed to test responses to different social signals.

A new wave of international research reveals that while high-intensity interval training (HIIT) delivers sweeping health benefits, it can also disrupt hormone balance—especially if done too often or without proper nutrition and rest. This has sparked growing interest and concern among fitness buffs and health professionals in Thailand, where HIIT classes and early-morning boot camps are booming. Understanding the nuanced impact of high-intensity exercise on the body’s delicate network of hormones is increasingly important for Thai readers eager to maximize the benefits of their workouts without jeopardizing long-term health or well-being.

A wave of international studies shows high-intensity interval training (HIIT) delivers major health benefits but can disrupt hormone balance when done too often or without proper nutrition and rest. In Thailand, where HIIT classes and early-morning boot camps are popular, these insights are prompting athletes and professionals to rethink routines for long-term health.

Thai fitness fans have embraced HIIT for fast results. Modern Bangkok gyms, Chiang Mai studios, and social media influencers often highlight high-impact sessions. Yet emerging research summarized by science commentators notes that excessive HIIT, or workouts under suboptimal conditions, can raise cortisol—the body’s stress hormone—and disturb other hormones such as estrogen, progesterone, and testosterone. The result can be fatigue, slower recovery, menstrual irregularities, and, paradoxically, hindered fat loss.

A wave of recent research is challenging the stereotype that men’s sexual health fades harmlessly with age, with new evidence suggesting that certain sexual health traits may be linked to longevity. Several academic and medical sources now indicate that men who maintain robust sexual health, including frequent sexual activity and normal testosterone levels, may enjoy a significant survival advantage compared to their peers.

The question of whether men who are sexually active or who display high sexual health indicators live longer has attracted scientific attention worldwide. In Thailand, where cultural discussions of male sexual wellbeing are often discreet, such research is particularly resonant as demographic shifts shape health policy priorities. The findings matter for Thai men and their families, integrating a vital aspect of sexual wellness into broader public health.

A growing body of research challenges the idea that men’s sexual health declines harmlessly with age. Studies suggest that maintaining robust sexual health, including regular sexual activity and healthy testosterone levels, could be associated with longer life for men.

Globally, scientists are exploring whether sexually active men live longer. In Thailand, where conversations about male sexual wellbeing are often discreet, these findings resonate as the country’s aging population grows. Understanding sexual health as part of overall well-being can inform policy and health services for Thai men and their families.

A recent study shows that natural hormone fluctuations during reproductive cycles can reshape the brain and sharpen learning abilities. Published in Neuron and led by researchers at a major U.S. university, the work demonstrates that rising estrogen levels alter neuron structure in the memory center of the brain and improve the brain’s ability to form mental maps of surroundings.

For Thai readers, this research reinforces that cognition is not fixed. Brain structure and function can shift with natural biological rhythms. The findings contribute to global conversations on gender, neuroscience, and education strategy, offering potential implications for how we approach teaching and student support in Thailand.

A groundbreaking new study reveals that the natural ebb and flow of hormones during the reproductive cycle can dramatically reshape the brain and sharpen learning abilities, promising to transform our understanding of cognition—and even hinting at new paths in personalized medicine. Published this week in the journal Neuron and led by researchers at the University of California, Santa Barbara, the research shows that cyclical changes in estrogen not only alter the physical structure of neurons in the memory-related hippocampus but also enhance the brain’s ability to form and maintain mental maps of our surroundings (Neuroscience News).

A groundbreaking study by researchers at Japan’s Fujita Health University has uncovered an unexpected role for brain-derived estrogen in directly regulating appetite and body weight, upending traditional beliefs about how hormones shape our eating habits. Their findings, recently published in The FEBS Journal, not only broaden our scientific understanding but could also open new avenues for treating obesity and overeating—issues of increasing significance in Thailand and around the world (PsyPost).

A new study from researchers at Fujita Health University in Japan reveals that estrogen produced in the brain may directly regulate appetite and body weight, challenging long-held beliefs about hormonal control of eating. Published in The FEBS Journal, the findings offer fresh directions for obesity research and potential future therapies relevant to Thai health priorities.

Traditionally, estrogen has been associated with reproductive health. Yet recent work shows the brain itself can synthesize estrogen, especially in the hypothalamus, via the enzyme aromatase. This neuroestrogen may influence behavior and physiological processes beyond reproduction. Until now, its direct impact on appetite remained uncertain, prompting interest from endocrinologists and neuroscientists worldwide.

A growing body of research and expert opinion is highlighting a silent yet serious consequence of excessive abdominal fat in men: a dramatic impact on hormonal balance, sexual health, and fertility. As obesity rates continue to rise—across the world and notably in Asian countries including Thailand—doctors are warning that belly fat is much more than a cosmetic concern. Landmark findings discussed by leading endocrinologists reveal that fat surrounding the waistline acts as an endocrine organ, disrupting testosterone levels and overall male vitality (The News).
