An anesthetic spray more than doubles the “lasting” time for men with premature ejaculation, according to a study by the company that makes the experimental spray.
The metered-dose, aerosol spray is a mixture of the anesthetics lidocaine and prilocaine. It is spritzed onto the tip of the penis 15 minutes before sex.
Before using the spray, the 54 heterosexual men in the study ejaculated, on average, one minute after vaginal penetration.
In the test, on four occasions, half the men used the anesthetic spray 15 minutes before sex, the other half a placebo with no active ingredients.
The men or their partners used a stopwatch to measure the time from vaginal penetration to ejaculation.
