Delayed ejaculation — sometimes called impaired ejaculation — is a condition in which it takes an extended period of sexual stimulation for a man to reach sexual climax and release semen from the penis (ejaculate). Some men with delayed ejaculation are unable to ejaculate at all.
Delayed ejaculation can be temporary or a lifelong problem. Possible causes of delayed ejaculation include certain chronic health conditions, surgeries and medications. Treatment for delayed ejaculation depends on the underlying cause.
It's normal for men to have delayed ejaculation from time to time. Delayed ejaculation is only a problem if it's ongoing or causes stress for you or your partner.
