New concepts in the diagnosis and treatment of premature ejaculation

Premature ejaculation is the most common male sexual dysfunction. The International Society of Sexual Medicine recently defined premature ejaculation as ejaculation less than about 1 min after penetration, inability to control ejaculation, and resulting negative personal consequences. Evolving treatments target the modulation of the neurobiological causes of the disorder. Current pharmaceuticals focus on aerosolized topical agents, selective serotonin reuptake inhibitors, 5-hydroxytryptamine receptor modulators, and opioid agonists. These emerging medications and the ability to tailor treatments based on genetic information likely will change the paradigm of this disorder and how it will be treated by clinicians.
