Study population

The ambulatory dietary advice center of university hospital in Naples recruited 140 obese men. They have an age from 35 to 55 years old and present an erectile dysfunction (score ≤ 21 on International Index of Erectile Function, IIEF score). The sweet diabetes, the cardiovascular disease and the hypertension constitute the criteria of exclusion. Finally, 110 obese men with an average age of 43 years presenting a sedentary lifestyle (less than one hour of physical exercise per week) are included. Their average BMI is 36.7 and their average erectile functional score is 13.7. A third party is a smoker.

Methodology

The participating subjects in this randomized study, are distributed in two groups. The men included in the group of intervention (n=55) receive personalized instructions by a dietitian and by a consultant in physical activities. They keep a diary and meet monthly within small groups. Besides, a psychological support is proposed.

The control group (n=55) receives information every two months as for a healthy diet and for the practice of physical exercises. The study takes place over two years.

A comparison is made of the average change of the IIEF score in both groups, between the beginning and the end of the follow-up. Besides, the modifications of blood pressure and the concentrations of cytokines, CRP, cholesterolemia, triglyceridemia, glycemia and insulinemia are also registered.

Results

Three men are lost sight in each of the groups. Four men included in the group of intervention and five in the control group resorted to drugs to improve the erectile function during the duration of the study.

After two years, the average BMI fell from 36.9 to 31.2 (difference: –5.7; p < 0.001) in the group of intervention and from 36.4 to 35.7 (difference: –0.7; p=0.19) in the control group. The physical activities also increased in a significant way for the group of intervention (p <0.001).

On the other hand, the average IIEF score rose from 13.9 to 17.0 (p<0.001) in the group of intervention and remained unchanged in the control group. Seventeen men in the group of intervention (31 %) have reached an IIEF score equal 22 or more. But, just three men (5 %) in the control group have IIEF score equal 22.

The multivariate analysis allowed to show that the loss of weight, the increase of physical activity and fall of CRP are associated with an improvement of the erectile function.

Conclusion

This study shows that (for men obese aged less than 50 years old and not presenting comorbidity) one man on three finds a complete sexual power thanks to prolonged, intensive and personalized support. This support allows him to reach a healthier lifestyle (especially loss of weight and more physical exercises).

The influence of the other factors which improve the sexual power, such as the stop of tobacco, was not studied however in this study.
