As one of the most common types of "urban diseases", sexual dysfunction has brought great trouble to a large number of male friends. Among these, premature ejaculation is the main factor affecting male sexual function. Clinical data shows that more than half of patients with sexual dysfunction are troubled by premature ejaculation. Premature ejaculation is a typical couple's disease, tormenting both men and women. Patients with premature ejaculation suffer from ejaculating too quickly, preventing both partners from fully enjoying the physical and mental aspects of intimacy. This can even lead to female sexual indifference. If left untreated for a long time, it may further result in male erectile dysfunction, such as weak erections or impotence, among other male functional disorders.
