Circumcision has shown no effect on PE. The International Society for Sexual Medicine guidelines do not recommend either surgical treatment due to the risk of permanent loss of sexual function and insufficient reliable data and on the basis of violating the medical principle of non-maleficence as the surgery can lead to complications, of which some might not yet be known. The most common complication of surgery is the recurrence of PE, reported to occur in about 10% of surgeries. Other sources consider SDN as a safe and efficient treatment and these surgeries are popular in Asian countries. Epidemiology
Premature ejaculation is a prevalent sexual dysfunction in men; however, because of the variability in time required to ejaculate and in partners desired duration of sex, exact prevalence rates of PE are difficult to determine. In the "Sex in America" surveys (1999 and 2008), University of Chicago researchers found that between adolescence and age 59, approximately 30% of men reported having experienced PE at least once during the previous 12 months, whereas about 10 percent reported erectile dysfunction (ED). Although ED is mens most prevalent sex problem after age 60, and may be more prevalent than PE overall according to some estimates, premature ejaculation remains a significant issue that, according to the survey, affects 28 percent of men age 65–74, and 22 percent of men age 75–85.
The DSM-5 allows for specifiers whether the condition is lifelong or acquired, applying in general or only to certain situations, and severity based on the time under one minute, however these subtypes have been criticised as lacking validity due to insufficient evidence.The 2007 ICD-10 defined PE as ejaculating without control, and within around 15 seconds. Treatments
Several treatments have been tested for treating premature ejaculation. A combination of medication and non-medication treatments is often the most effective method. Self-treatment
Many men attempt to treat themselves for premature ejaculation by trying to distract themselves, such as by trying to focus their attention away from the sexual stimulation. There is little evidence to indicate that it is effective and it tends to detract from the sexual fulfilment of both partners. Other self-treatments include thrusting more slowly, withdrawing the penis altogether, purposefully ejaculating before sexual intercourse, and using more than one condom. Using more than one condom is not recommended as the friction will often lead to breakage. Some men report these to have been helpful.A qualitative clinical trial, conducted by Kings College London medical school teaching hospitals, compared use of the Prolong device with cognitive behavioural therapy.
