Research on the changes that come with age in men, and the habits that slow them.
Researchers followed 1,220 men at a Utah fertility clinic and matched the outdoor heat and humidity each man lived through while his sperm were forming against a molecular measure of…
This study looked at whether low testosterone in middle-aged and older men is tied to worse blood vessel health through effects on mitochondria, the tiny power plants inside cells. Researchers…
This study looked at whether wine drinking affects biological aging in men, using data from the Moli-sani Study in Italy. It tracked over 22,000 adults, comparing how much wine they…
This study looked at whether resistance exercise and a high-protein diet could improve metabolic flexibility (the body's ability to switch between burning carbs and fats for fuel) in older men.…
This study set out to assess how exercise affects bone mineral density (BMD) in middle-aged and older men, focusing on different skeletal sites. It pooled data from randomized controlled trials…
This study looked at how a lifetime of endurance exercise affects heart health and muscle strength in older men. It followed 59 men, average age 67, who had been doing…
This study looked at whether vitamin D levels are linked to metabolic health, measured by the TyG index (a score from fasting blood sugar and triglycerides that flags insulin resistance,…
This review looked at how aging affects men's hormones, sleep, and metabolism, centering on two kinds of hypogonadism (when the testicles do not make enough testosterone, causing symptoms like low…
This study looked at whether ashwagandha (an herbal supplement traditionally used to blunt stress) helps team-sport athletes handle the strain of pre-season training, when the stress hormone cortisol and fatigue…
This review set out to examine how microplastics (tiny plastic particles) affect the male reproductive system at the cellular and molecular level. It compiled findings from multiple studies across scientific…
This study looked at whether vitamin D levels in the blood are linked to developing sarcopenia (age-related muscle loss) in older adults. It followed 1,292 Korean adults aged 70-84 without…
This study set out to explore how trace elements in the blood might relate to testosterone levels and symptoms like low energy, mood issues, and sexual health in young men.…
This study set out to see how lifestyle and insulin resistance relate to male fertility. Insulin resistance means the body has stopped responding properly to insulin, so it takes more…
