Delayed ejaculation is a man's inability for or persistent difficulty in achieving orgasm, despite typical sexual desire and sexual stimulation. Generally, a man can reach orgasm within a few minutes of active thrusting during sexual intercourse, whereas a man with delayed ejaculation either does not have orgasms at all or cannot have an orgasm until after prolonged intercourse which might last for 30–45 minutes or more. In most cases, delayed ejaculation presents the condition in which the man can climax and ejaculate only during masturbation, but not during sexual intercourse. It is the least common of the male sexual dysfunctions, and can result as a side effect of some medications. In one survey, 8% of men reported being unable to achieve orgasm over a two-month period or longer in the previous year.
