Doctors warn against unproven testosterone supplements as levels decline across generations

Urology specialist Dr. Leonid Bukhanov has revealed that testosterone levels in modern men are lower than those of their fathers at the same age, noting that this decline is continuing across generations.

Bukhanov explained that the main causes of falling testosterone are linked to lifestyle factors. Excess weight can convert some testosterone into female hormones, while lack of physical activity and sedentary office work reduce its production.

He added that chronic stress and insufficient sleep negatively affect the entire hormonal system.

He also pointed out that certain environmental substances, such as compounds found in plastics, household chemicals, and packaging materials, may impact testosterone levels.

Symptoms of low testosterone can include loss of energy, reduced libido, irritability, and increased abdominal fat.

Bukhanov confirmed that men aged 30 to 35 who are overweight and chronically sleep-deprived may have testosterone levels similar to much older men. However, he said that lifestyle improvements—such as weight loss, regular exercise, and adequate sleep—can restore hormone levels to normal.

The doctor warned against relying on testosterone boosters and supplements promoted in advertisements, stressing that their effectiveness is unproven and that uncontrolled use may suppress the body's natural hormone production.

He advised focusing on weight management, strength and fitness training, sufficient sleep, stress reduction, and treating underlying medical conditions.

If testosterone remains low despite these measures, Bukhanov emphasized the importance of consulting a specialist, stating that improving overall health is the key to naturally increasing hormone levels.
