Conditions: Anejaculation

Overview - Anejaculation

Anejaculation is defined as the inability to ejaculate semen; the word itself means “no ejaculation.” With this condition, a man can produce sperm but cannot expel them during normal ejaculation even though anejaculation often is accompanied with normal orgasmic sensation.

Anejaculation can be divided into several categories:

  • Situational anejaculation: Situational anejaculation is when a man can ejaculate in some situations but not in others. Frequently, this type of anejaculation is caused by stress in situations such as being in the fertility clinic where some men become tense when they know they have to give a semen sample “on demand.” Additionally,  if a man can ejaculate during intercourse but cannot ejaculate through masturbation (or vice versa) then this is considered situational.
  • Total anejaculation: Total anejaculation is when a man is never able to ejaculate semen either during intercourse or by masturbation, at home or in the clinic. Total anejaculation also can be divided into:
    • Anorgasmic anejaculation - a man who can never achieve an orgasm while awake, but can reach orgasm, and ejaculation, while asleep at night. In these cases, psychological factors rather than physical ones are likely causing the condition
    • Orgasmic anejaculation - a man can reach and achieve orgasm, but cannot ejaculate semen. This failure to release semen can be due to a block in the tubes or damage to the nerves, or possibly due to retrograde ejaculation where semen is going into the bladder rather than leaving the penis through its tip

Anejaculation can also be classified as primary or secondary.  Primary anejaculation is when ejaculation has never been experienced in a man's entire lifetime and secondary anejaculation is when a man is unable to ejaculate after he has been experiencing normal sexual functioning.
