What is anejaculation?

Anejaculation is the inability to ejaculate semen despite stimulation of the penis by intercourse or masturbation. It is a fairly common problem and can be very distressing to a couple trying for a child.

Since it's not a common problem and is often confused with erectile dysfunction, let me describe this is in more detail. The man has normal libido; gets aroused; gets an erection; and gets an orgasm, but no semen spurts out from the erect penis. After the orgasm, he loses the erection.

Anejaculation is a diagnosis that is best made by the patient himself. However, it's often difficult for the patient to explain what's happening to the doctor, hence this creates a lot of confusion. Please go step by step.

Do you have normal sexual desires? Do you get a good erection? Do you feel an orgasm? Do you lose the erection after your orgasm?

It can be especially difficult for men who have never experienced an orgasm to describe their problems accurately.

It's easy to confuse some conditions with anejaculation. The commonest is called retrograde ejaculation. In this case, the semen goes backward into the urinary bladder, rather than forward through the erect penis. In this case, the post-orgasm urine is cloudy and turbid; and if this is sent to the lab for examination, the doctor will find sperm in the urine. You can read about this at

Men with a very low volume ejaculate ( for example, those with an absent vas deferens) will also have difficulty in making the right diagnosis. Though they do ejaculate semen, the volume is so small that they sometimes feel that they do not have any ejaculate at all!

What causes anejaculation?

Anejaculation may be situational or total.

  • Situational anejaculation - in this condition, the man is able to ejaculate in some situations but not in others. Typically, situational anejaculation is stress-induced and occurs selectively in the infertility clinic or at the time of ovulation or egg pick-up during an IVF (In Vitro Fertilization) cycle. Thus, a man who is able to ejaculate at home may be unable to do so in the clinic because he is self-conscious and anxious. Similarly, some men become tense when they know they have to give a semen sample and hence usually fail on demand even though they are able to ejaculate on other occasions. Another common type of situational anejaculation when a man can ejaculate during intercourse but is unable to collect a sample by masturbation because he is not accustomed to doing so.
  • Total anejaculation - in this condition, the man is never able to ejaculate semen consciously, either during intercourse or by masturbation, at home or in the clinic. Total anejaculation is further divided into anorgasmic anejaculation and orgasmic anejaculation.

Anorgasmic Anejaculation - these men never reach orgasm in the waking state (either by masturbation or by intercourse), and hence do not ejaculate. However, nocturnal emissions are usually present. There is no physical defect. This failure to reach orgasm is sometimes due to psychological inhibitions. Alternatively, some men need a high amount of stimulation before they reach orgasm and do not get this stimulation during intercourse or masturbation.

Orgasmic Anejaculation - these men reach and experience an orgasm but they do not ejaculate semen, either because there is a failure of emission of semen (due to a block in the tubes or damage to the nerves) or because there is retrograde ejaculation (flow of semen back into the bladder due to weakness of the bladder neck).

How is anejaculation treated?

Situational anejaculation can often be prevented or treated by simple measures. The semen collection room in an infertility clinic should be in a quiet, discreet location and there should not be a queue of men waiting to use it! If you find the clinic environment is unfavorable discuss it with the doctor and ask if you can bring the semen sample from home (if you stay close by) or from a nearby hotel room.

What to do if you cannot give a semen sample

Sometimes Viagra helps. Viagra by itself does not facilitate ejaculation. However, if you are having difficulty getting an erection, Viagra could help you with that, thus making it easier to masturbate. If you anticipate having difficulty giving a semen sample (based on past experience) on the day of egg pick-up you could request your doctor to collect and freeze your semen beforehand on a day when you are relaxed. In fact, some centers routinely freeze a semen sample from all couples undergoing IVF (In Vitro Fertilization) since unexpected failure to collect semen, due to the stress of IVF (In Vitro Fertilization), is quite common.

If you have difficulty masturbating, but can ejaculate during intercourse, do not be disturbed. Many men are unable to masturbate. Discuss this with your doctor and arrange to collect the semen at home by coitus interruptus. This means having intercourse till the moment when ejaculation is about to happen. Withdraw the penis at that moment and catch the semen in the collection beaker. If that does not work, you can request your doctor for a non-spermicidal non-toxic condom made of silastic. You can buy one from our Online Store! This would allow you to have full intercourse and ejaculate into the condom from which the semen is then collected. NOTE: Condoms that are routinely available are coated with a chemical that kills sperm and should not be used for collecting semen.

Finally, some men with situational anejaculation are just not able to collect a sample when required. Discuss this with your doctor beforehand. He will teach you how to use a vibrator to stimulate the penis and collect a sample. A couple of practice sessions should be done before the actual day of collection.

Anorgasmic Anejaculation can be difficult to treat. If there has been a traumatic sexual episode in the past that you are aware of, discuss it with your doctor or ask for a referral to a sexologist or psychologist. If your doctor feels that you are sexually inhibited he may suggest a similar referral.

However, in most cases, counseling is not required. The main treatment for anorgasmic anejaculation is the use of a vibrator. The vibrator acts by providing a strong stimulus, for a long duration, to the penis (use of the vibrator is described below). Due to the stimulation the man reaches orgasm and ejaculates. Vibrator stimulation results in ejaculation in about 60% of men.

If vibrator therapy fails, electro-ejaculation can be performed. Electro-ejaculation involves the direct electrical stimulation of the nerves to the seminal vesicles and terminal vas. The most commonly used device is the Seager electro-ejaculator which delivers a sine wave, alternating current. The procedure is carried out under general anesthesia (except in paraplegic men with no sensations). The electrodes are mounted on a cylindrical rod which is lubricated and introduced per rectum with the electrodes facing the prostate gland. The voltage is turned up to 5 volts, held for a second, and then turned back to 0 volts. For the next stimulus, the voltage is increased to 6 volts. The stimulus is progressively increased until ejaculation occurs. If the antegrade ejaculate is scanty, the bladder is catheterized to check for retrograde ejaculation. Electro-ejaculation will always succeed in men with anorgasmic anejaculation since there is no physical defect. However, electro-ejaculation needs general anesthesia and the semen quality may be inferior. Hence, it is always a second choice to be used only if repeated sessions with the vibrator fail.

Orgasmic Anejaculation Since this condition is due to a physical problem, treatment will depend on the type of problem.

If the nerves are damaged sometimes medicines can help. If medicines do not work, vibrator stimulation or electro-ejaculation will usually be successful in obtaining a sample.

If there is a block due to infection, this can sometimes be cleared by surgery. If surgery fails or is not possible, then pregnancy can be achieved by aspirating sperm from the epididymis and using these sperm for ICSI (test-tube baby procedure).

How to use a vibrator:

The vibrator works by providing a high-intensity stimulus to the penis. This stimulus is strong enough to overcome any psychological or situational inhibition and trigger the orgasmic reflex. This is what a vibrator looks like. You can buy one from our Online Store!

The procedure should be carried out in a room with complete privacy. It is very important to remember that ejaculation will occur automatically as a result of the vibratory stimulation - so be relaxed; do not try and force ejaculation.

Pass urine, take off your clothes, and sit on a bed with your legs apart. The vibrator is placed beneath the penis. The penis is placed upon the vibrating head such that the undersurface of the penis (glans and distal shaft) is stimulated. Once you are comfortable with the vibratory sensation, press the tip of the penis (glans) upon the vibrator such that you feel the maximum amount of stimulation. Keeping the vibrator in place, close your eyes, and fantasize sexually. Stimulation is continued till ejaculation occurs. This usually occurs in 10 to 30 minutes but some men with anorgasmic anejaculation, who have never experienced an orgasm, may take up to 2 hours of stimulation before they reach orgasm the first time! This period shortens during subsequent sessions. Some men require a second or third session before they succeed.

In Summary

Failure to ejaculate is a common problem. If you suffer from this condition do not be disheartened. A variety of therapies are available to solve the problem. Some men with being helped by the simple measures described above for situational anejaculation. Others will be helped by the use of a vibrator or an electro-ejaculator. Finally, if nothing else works, sperm can be retrieved directly from the epididymis or testis and used for ICSI.
