forcible, sudden expulsion; especially expulsion of semen from the male urethra, a reflex action that occurs as a result of sexual stimulation. adj., adj ejac´ulatory. The three components of semen are expelled in quick succession. First to emerge is a lubricating fluid produced by the bulbourethral glands in the penis; next comes a fluid released into the urethral channel by the prostate, providing a neutral medium within which the sperm cells can swim; and lastly, the spermatic fluid, which has been stored in the seminal vesicles, is likewise injected into the urethral channel and ejaculated. See also reproduction.

Persistent difficulty in ejaculating despite normal sexual desire and stimulation.

Most men can achieve orgasm within 5 minutes of active thrusting during sexual intercourse; those with delayed ejaculation either do not have orgasms, cannot ejaculate without prolonged intercourse lasting up to an hour or more, or can do so only while masturbating.
