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

The 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 emitted the greatest quantity of sperm. With each subsequent convulsion sperm count is reduced, and a 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.

Phases of Ejaculation

There are two phases of ejaculation: elimination phase and the phase of the discharge, directly or 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, so that 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 are also part of orgasm in men. Typical male orgasm lasts 17 seconds, but its length may vary from a few 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 reduction occurs at an interval 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.

The volume of ejaculate

The power 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, it is possible to decrease the volume and the age.

The number of sperm in the ejaculate can also be very different; it depends on many factors, including the time preceding an ejaculation, the duration of sexual stimulation preceding ejaculation, as well as age, testosterone Five myths about testosterone , Nutrition, hydration and the total volume of semen. 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.

The 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.

Premenstrual syndrome

Premenstrual syndrome - a huge problem for many women, and most doctors agree that PMS affects women and sex hormones, as a result, her sexual desire.

According to one theory, premenstrual syndrome is associated with fluctuations in levels of the hormone progesterone. As we already know, progesterone Progesterone - norm and pathology   - One of the major female sex hormone, and its level increases significantly in the second half of the cycle, just before the start of menstruation.

Some experts believe that libido problems arise when the progesterone level is not high enough. However, PMS is not a gradual change in the level of progesterone, and the results of clinical trials do not allow an unambiguous conclusion.

Nevertheless, many gynecologists prescribe their patients progestogens - a synthetic form of progesterone, although there is no conclusive physiological justification for such treatment. Unfortunately, progesterone is not effective when administered orally, and used in the form of rectal suppository that is large enough not all women.

Low sexual desire or no menstruation before - just one of the many problems faced by women with PMS. By the way, there is evidence that if a woman still making love at this time, even without being a great desire, her health will improve, because sex helps to relax and relieve tension.

Follow the diet

Also, nutrition plays an important role in the treatment of loss of desire. At the disposal of contemporary women are many alternatives to prevent loss of libido before menstruation. In the West, many health food stores offer supplements that can actually help to increase sexual desire. This method of neutralizing the "side effects" of premenstrual syndrome was discovered almost by accident, when it was revealed that the dietary food with mineral additives not only eases PMS, but also increases the libido.

It is appropriate to mention phytoestrogens (naturally occurring estrogens). In the last ten years there has been a surge of interest in phytoestrogens, especially in the context of the treatment of menopause. Perhaps it is sufficient to change the diet, include more natural estrogens of plant origin, to improve the overall health and increase sexual desire before menopause. However, some experts believe that premenstrual syndrome occurs due to a lack of progesterone, while, according to many women receiving estrogen herbal preparations Estrogen - the key to bone health For example, red clover helps to reduce the symptoms of PMS.

Does this mean that premenstrual syndrome is not associated with low levels of progesterone, and is caused by a critical decrease in estrogen levels before menstruation? It seems the answer is nobody knows.

Menopause

About hormone levels during menopause is known more, although much of the data are contradictory. Also, doctors pay little attention to such "trifles", as a loss of sexual desire. They are much more interested in how to prevent bone loss and heart disease. The situation is complicated by the side effects of hormone replacement therapy (HRT). In 2002-2005, it was found out that the effects and side effects of hormone replacement therapy is much more used to be considered.

As hormone therapy affects the sex? According to experts, HRT allows women to feel much healthier and more energetic, which increases her sexual desire.

Many women during menopause are experimenting with food, enriching the diet of foods high in estrogen and food additives Food additives - basic classification   (soy and red clover). One of the main advantages of this dietetic foods is that it enhances the production of natural lubrication in the vagina. Although vaginal dryness Vaginal dryness: Causes and Symptoms   can not be considered an indicator of the loss of sexual desire, sex becomes uncomfortable for women because of what she may lose interest in him.

So, whether the loss of sexual desire caused by hormones? There is no consensus on this account does not exist: many doctors and scientists believe that increased levels of testosterone in the blood can increase sexual desire and "cure" from the loss of libido, but there are other points of view. One thing is clear: there are several ways to resolve this common problem, and only you can decide which one is right for you.
