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).

As Thai families celebrate their children’s first loose tooth—a familiar childhood milestone—they may be witnessing another, far more hidden transformation: a dramatic shift in the child’s brain known as “wobbly-tooth puberty.” According to new research highlighted in sources such as the BBC’s recent feature and supported by studies published in Nature Human Behaviour, the age of six marks the beginning of “middle childhood,” a developmental stage long overlooked by scientists but now revealed to be a crucial turning point for both brain function and emotional intelligence (BBC Future; Nature).

A groundbreaking 2024 study published in Nature’s Digital Medicine Journal has found that patterns in resting heart rate and heart rate variability, measured by wearable devices such as Whoop trackers, may reveal important insights into female reproductive health. Conducted with data from over 11,500 users worldwide, this research is among the largest and most comprehensive to date exploring the connections between cardiovascular metrics and menstrual cycles, potentially paving the way for more accessible health monitoring for women everywhere, including Thailand.

Shoulder knots and chronic upper body tension are everyday struggles for millions of office workers—especially in busy urban centers like Bangkok, where a typical workday means hours at a desk, hunched over a screen. A recent popular feature from Fit&Well describes a firsthand trial of four stretching exercises designed to relieve stubborn shoulder knots, with surprisingly positive, lasting results in less than 10 minutes a day. This personal discovery aligns with a growing body of medical research showing that targeted stretching routines can do far more than provide fleeting comfort—they may actually improve pain, mobility, and quality of life for people suffering from muscle tension or pain linked to poor posture and repetitive activities (Fit&Well, 21 April 2025).

Cutting-edge research has pulled back the curtain on the brain’s secret playbook for learning, unveiling rules that govern how we master new skills and knowledge—a discovery with profound implications for both education and artificial intelligence (AI). Scientists, backed by the U.S. National Institutes of Health (NIH), harnessed revolutionary synapse imaging technology to observe real-time changes among the brain’s neurons during learning, uncovering patterns that promise new understanding of how we become smarter—with practical lessons for schools in Thailand and emerging AI technologies worldwide SciTechDaily.
