Objectives: to evaluate the effectiveness of a natural compound made of Ecklonia bicyclis Seaweed, Tribulus terrestris and water-soluble chitosan oligosaccharide, in the male sexual asthenia with mild or mild-moderate erectile dysfunction and serum testosterone levels between 280 and 350 ng/dl. Materials and Methods: 84 male patients affected by reduced libido and serum testosterone levels at the lower limit of normal, were recruited. We have separated patients in three different age groups: group A (18 - 45 years), group B (45 - 59 years), group C (>60 years). All subjects answered the International index of erectile function questionnaire (IIEF-5) and underwent determination of serum total testosterone before and after 30 days of treatment. Results: Before treatment, the group A showed mean (± standard deviation) total testosterone 321.9 ± 19.2 ng/dl and mean IIEF-5 18.6 ± 1.97, in the group B it was 318.5 ± 18.1 ng/dl and 16.3 ± 2.66, and finally in the group C it was 305.4 ± 13.1 ng/dl and 14.2 ± 1.95 respectively. After treatment mean total testosterone and mean IIEF-5 were respectively: group A (448 ± 111.46 ng/dl and 21.84 ± 3.41); group B (453.8 ± 105.23 ng/dl and 20.4 ± 3.81); group C (385.8 ± 87.29 ng/dl and 16.7 ± 3.84). Conclusions: The treatment with Ecklonia bicyclis, Tribulus terrestris and water-soluble chitosan oligosaccharide might represent a safe and effective option on the improvement of libido and erectile function in man with testosterone level at the lower limit of normal.
