Chronic psychological stress is linked to lower morning testosterone in men, largely because sustained HPA axis cortisol output can suppress hypothalamic-pituitary-gonadal (GnRH/LH) signaling and reduce testicular testosterone production. Here is how to recognize the stress-low T feedback loop and what actually helps break it. “Stress and testosterone talk to each other all day long. Short ...

Semen retention is deliberately avoiding ejaculation for a period of time. Research suggests it does not produce a sustained testosterone boost.

Converse-style zero-drop, incompressible flat soles can improve center-of-pressure stability and reduce energy loss from sole compression in deadlifts, but for squats they remove the 0.75 to 1 inch heel lift that helps ankle dorsiflexion. If mobility is restricted, that can increase knee and lumbar torque. Here is how to know when flat shoes are the ...

Which essential biomarkers runners should track? The lab numbers that predict fatigue and low testosterone

The essential biomarkers runners should track include vitamin D, iron and ferritin, magnesium and potassium, C reactive protein, testosterone, cortisol, blood glucose, and performance markers like VO2 max, lactate threshold, and resting heart rate. When those numbers drift, your training can feel harder, recovery slows, and injury risk rises even if your mileage looks “perfect.” ...

Testosterone before and after: What men can realistically expect from TRT

Dr. Alexander Grant, MD, PhD: Urologist & Men's Health Advocate

Testosterone before and after changes are real for many men with confirmed testosterone deficiency, most often showing up as better energy, libido, and body composition when treatment is correctly chosen and monitored.
