Premature ejaculation is currently recognized as ejaculation before or within 1 minute after vaginal penetration, with reduced ejaculatory control and adverse psychological and emotional effects on both partners. Studies have shown that the average ejaculation time is 7-13 minutes. Individuals believe that each person has different needs and the diagnosis of premature ejaculation needs to be individualized. The etiology is not well understood and may be related to a low excitability threshold in the brain, high glans sensitivity and psychological state. The current treatment is based on oral medication and glans-applied medication, followed by behavioral therapy and surgical treatment. The latter is inaccurate and invasive, and has not been used in most clinics. There are now specialized medications for premature ejaculation that can be taken as needed and have a quick onset of action. Other drugs include sertraline, paroxetine and other 5-hydroxytryptamine inhibitors, but they need to be taken for more than 2 weeks to achieve the best results. Adverse effects of these drugs include headache, diarrhea, and nausea. The main purpose of glans application is to reduce penile sensitivity, commonly used drugs are lidocaine gel, oxycodone syrup, applied about 10 minutes before intercourse, but easy to cause penile numbness. Behavioral therapy requires a professional psychiatrist and the cooperation of both parties. In short, the diagnosis and treatment of premature ejaculation varies from person to person, so don’t take the liberty of diagnosing and treating it, but you also need to go to a regular hospital.
