Ejaculation: From 3 Different Sources

Emission of semen from the penis at orgasm. Shortly before ejaculation, the muscles around the epididymides (the ducts where sperm are stored; see epididymis), the prostate gland, and the seminal vesicles contract rhythmically, forcing the sperm from the epididymides to move forwards and mix with secretions from the seminal vesicles and prostate. At ejaculation, this fluid is propelled through the urethra and out of the body.

Because both semen and urine leave the body by the same route, the bladder neck closes during ejaculation. This not only prevents ejaculate from going into the bladder but also stops urine from contaminating the semen (See also reproductive system, male.)

The expulsion of SEMEN from the PENIS during ORGASM. The stimulation of sexual intercourse (coitus) or masturbation produces a spinal re?ex action that causes ejaculation. As well as containing spermatozoa (male germ cells), the semen comprises several constituents arising from COWPER’S GLANDS, the PROSTATE GLAND, the testicles and seminal vesicles (see TESTICLES) and these are discharged in sequence. (See also PREMATURE EJACULATION.)

Premature Ejaculation

A disorder in which EJACULATION of semen occurs before or immediately after the penis penetrates the vagina during sexual intercourse.

Sexual counselling may help to alleviate the condition.... premature ejaculation

Ejaculation, Disorders Of

Conditions in which the normal process or timing of ejaculation is disrupted.

In premature ejaculation, emission of semen occurs before or almost immediately following penetration. Premature ejaculation is the most common sexual problem in men, and is often due to over-stimulation or anxiety about sexual performance. If the problem occurs frequently, sexual counselling and techniques for delaying ejaculation may help (see sex therapy).

Inhibited ejaculation is a rare condition in which erection is normal, or even prolonged, but ejaculation is abnormally delayed or fails to occur. The problem may be psychological in origin, in which case counselling may help, or it may be a complication of a disorder such as diabetes mellitus or alcohol dependence. In some cases, inhibited ejaculation occurs as a side effect of particular drugs, such as some antihypertensive and antidepressant drugs.

In retrograde ejaculation, the valve at the base of the bladder, which normally closes during ejaculation, stays open. As a result, ejaculate is forced back into the bladder. Retrograde ejaculation may occur as a result of a neurological disease, after surgery on the bladder or prostatectomy. There is no treatment, but intercourse with a full bladder can sometimes result in normal ejaculation.
