Detailed Description

The study involves the recruitment of 35 functional hypogonadal patients aged between 50 and 75 years to the Andrology Unit of the "Antonio Cardarelli" Hospital. At T0 patients will undergo hematochemical evaluation of the following parameters: total and free testosterone, PSA and hematocrit.

At the same time, they will be provided with a self-assessment questionnaire on physical and sexual functioning. The same evaluations will be performed after 3 months of supplementation (T1).

The main endpoint is the intra-subject variation in total and free testosterone levels between T0 and T1.
