Obesity Diminishes Sexual Function in Young Men
Obesity can lead to a deterioration of erectile function in young men.
In a study of 136 men aged 20–49 years, researchers found a significant decrease in total testosterone in obese 30-year-olds compared with men who had a normal body mass index. In obese 40-year-olds, the researchers also observed decreased luteinizing hormone and sex hormone binding globulin.
Erectile function and morning erections were adversely affected by higher BMI and waist-to-hip ratio, and positively correlated with free testosterone index.
