The traditional belief is that premature ejaculation and impotence are only differences in the severity of the condition. Premature ejaculation is a mild or early manifestation of impotence. Erectile dysfunction is the result of premature ejaculation. Some people refer to premature ejaculation and impotence as a pair of difficult siblings.
Modern medicine believes that premature ejaculation and impotence are two different diseases, and there is a clear difference between the two. Although premature ejaculation and impotence have the same functional impairment, there are differences in sexual dysfunction such as libido disorders, erectile dysfunction, sexual intercourse disorders, orgasmic disorders, and ejaculation disorders. Premature ejaculation belongs to the disorders of sexual desire, orgasm, and ejaculation.
