Erectile dysfunction has always been one of the main diseases troubling men. Urologists point out that if a man, in the presence of sexual stimulation and desire, experiences inability to achieve erection, insufficiently firm erection, or brief erection duration, leading to inability to normally complete sexual intercourse, this is defined as erectile dysfunction, abbreviated as "ED". However, due to the high incidence of erectile dysfunction, its very complex causes, and the difficulties in treatment, how to prevent impotence has already become a focus of attention for a large number of men.
