Perception of sexuality varies considerably from population to population and their cultural inheritance, depending on whether you consider occidental, oriental or African cultures. In a wider concept of environment, worries, anxiety or stress induced by work, family, social and economic factors may have a negative impact on sexual functions. Quantitative surveys on sexuality try to measure the incidence of love feelings on sexual behaviour but they cannot determine the close overlaps between mind and body. To give his partner satisfaction, men do not always need performing well. Men also have right to love women, their own ways and according to their means. Impotence or erectile dysfunction (ED) is nowadays a subject that is more and more studied on conceptual, epidemiological as much as clinical levels. Taking this trouble into consideration is relatively new for the general public and seems to coincide with the launching towards the end of the last decade of the first real effective oral treatment, the phosphodiesterase 5 (PDE5) inhibitors and of the communication developed around this event. Demand for sexual problems management seems to be on the increase.
