In the Diagnostic and Statistical Manual of Mental Disorders, 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.
Of note, most men's intravaginal ejaculation latency time range is approximately 4 to 10 minutes.
[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.
Retraining masturbatory practices and re-calibrating the mismatch of sexual fantasies with arousal are essential when these are contributing to DE.
[36] Therapy usually involves homework assignments and exercises intended to help a man get used to having orgasms through insertional intercourse, vaginal, anal, or oral, that is through the way to which he is not accustomed.
Limited data has shown that the drug amantadine may help to relieve SSRI-induced orgasmic dysfunction.
[40][41][42] Cyproheptadine, buspirone, stimulants such as amphetamines (including the antidepressant bupropion), nefazodone has been used to treat SSRI-induced anorgasmia.
