Premature ejaculation is the most common ejaculatory dysfunction, with an incidence of more than 1/3 of adult men. The definition of premature ejaculation is still controversial and is usually evaluated by the ejaculatory latency of men or the frequency of women reaching orgasm during sexual intercourse, such as the standard of men losing the ability to control ejaculation during sexual intercourse and ejaculating before or just after penile insertion into the vagina; or the standard of women reaching orgasm less than 50% of the time during sexual intercourse to define premature ejaculation, but these are not universally accepted. The ejaculatory latency of men is affected by age, length of abstinence, physical condition, emotional psychology and other factors, while the frequency of female orgasm is also affected by physical state, emotional changes and the surrounding environment.
