Delayed ejaculation

Delayed ejaculation (DE) describes a man's inability 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.^[1] Delayed ejaculation is closely related to anorgasmia.

In the Diagnostic and Statistical Manual of Mental Disorders (DSM), fifth edition, the definition of DE requires 1 of 2 symptoms: either a marked delay in or a marked infrequency or absence of ejaculation on 75% to 100% of occasions for at least 6 months of partnered sexual activity without the individual desiring delay, and causing significant distress to the individual. DE is meant to describe any and all of the ejaculatory disorders that result in a delay or absence of ejaculation. The Third International Consultation on Sexual Medicine defined DE as an IELT threshold beyond 20 to 25 minutes of sexual activity, as well as negative personal consequences such as bother or distress. Of note, most men's intravaginal ejaculation latency time range is approximately 4 to 10 minutes. While ejaculatory latency and control were significant criteria to differentiate men with DE from those without ejaculatory disorders, bother/distress did not emerge as a significant factor.^[2]

Delayed ejaculation 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.^[3] DEs are either primary and lifelong or acquired. Acquired DEs may be situational. While most men do experience occasional or short term delayed ejaculation issues, the prevalence of lifelong DE and acquired long term DE is estimated around 1% and 4%, respectively.^[4]
