- Obesity is a major cause of low testosterone levels
- Hypogonadism is found in 75% of men considered very obese (BMI >40 kg/m2)
The link between obesity and low testosterone levels is found in men at all ages, even in young men and teenagers
The common decrease in testosterone seen in older men is not due to age, but rather to increasing body weight
- Testosterone decreases seen in men as they get older can be reversed with weight loss
