If you have premature ejaculation, you need to see the urology department or the male department, because nowadays the subspecialties are more specialized and many hospitals may have a separate male department. If there is a separate male department, it is recommended to see the male department. Premature ejaculation is a very common sexual dysfunctional disease among men, and there is still some controversy about the diagnosis of premature ejaculation. The first-line drug for premature ejaculation is dapoxetine, which is usually taken one hour before the start of sexual life and is effective within 24 hours. It has a relatively clear effect on prolonging sex, so it can be the drug of choice to treat premature ejaculation. There are some anti-anxiety drugs that also have a more significant efficacy for prolonging sexual life, such as sertraline. At the same time, patients should usually strengthen physical exercise, to ensure the quality of rest, conditioning their own physical conditions, for improving sexual function also has a very good promotion effect.
