Ejaculation: an essential part of man's life
Ejaculation - is the emission of semen from the penis, usually accompanied by orgasm.In most cases ejaculation results from sexual stimulation, including stimulation of the prostate.In rare cases, this is due to prostate disease.Ejaculation can occur spontaneously, such as during sleep Dreams: how to understand our dreams ;Some men have such infringement, as the inability to ejaculate.
Ejaculation and orgasm
process of ejaculation is a very strong sense of a part of an orgasm.The most powerful sensations usually during the first and second convulsion, but then thrown out the greatest number of sperm.With each subsequent convulsion sperm count decreases and the wave of pleasure is becoming weaker.During sexual intercourse or masturbation most men it is very difficult to resist the urge to continue to stimulate the penis, when they start to feel the approach of orgasm.
ejaculation There are two phases: the phase of removal and ejection phase, or directly ejaculation.During the elimination phase control ejaculation reflex sympathetic nervous system and the discharge phase is controlled by the spinal cord reflexes.During the elimination phase vas deferens cut, allowing the sperm travels from the epididymis into the vial of the vas deferens.Usually, the beginning of the elimination phase man feels as a "point of no return", also known as point of ejaculatory inevitability.Then the sperm passes through the vas deferens, mixed with fluids from the seminal vesicles, prostate and bulbourethral glands to form the ejaculate.
When the phase of ejection, the ejaculate is ejected through the urethra with the rhythmic muscle contractions.
These rhythmic contractions of orgasm are also part of men.Typical male orgasm lasts 17 seconds, but its duration can vary from several seconds to one minute;most men during orgasm is derived from 10 to 15 muscle contractions.The frequency of contractions during orgasm is gradually reduced.The first cuts occur at intervals of 0.6 seconds, then each successive reduction intervals are increased by 0.1 second.
Many men also experience irregular cuts for some time after the orgasm.
Ejaculation begins during the first or second convulsion, most men - in the first.
volume of ejaculate
strength of ejaculation and ejaculate volume may differ from men.The volume of seed in normal ejaculation varies from 1.5 to 5 ml.On the volume of ejaculate it affects how much time has passed since the last ejaculation.The largest volume of ejaculate observed after prolonged abstinence.The duration of stimulation, which led to ejaculation, too, can affect the amount of seed.Abnormally low volume of ejaculate called Parvisemia;However, its volume can be reduced and age.
number of sperm in the ejaculate can also be very different;it depends on many factors, including the time of the last ejaculation, the duration of sexual stimulation preceding ejaculation, as well as the age, testosterone levels Five myths about testosterone , nutrition, hydration, and the total volume of seminal fluid.Abnormally low sperm count is called oligospermia, and the absence of sperm in the ejaculate - azoospermia.
After ejaculation in most men should take some time before they will again be able to ejaculate.Typically, young men, the gap is quite short, and it increases with age.
duration of sexual stimulation to ejaculation can be very different.There violations such as premature ejaculation and anorgasmia, or the inability to ejaculate, even though the desire to do so.Orgasm without ejaculation is called a dry orgasm.
