Ejaculation may be timely

Ejaculation – the release of ejaculate (seminal fluid, semen) from the urethra during sexual intercourse or forms of sexual activity that replace it (masturbation, petting, pollutions, oral sex).

Ejaculation, like an erection, is a reflex act. This is a more complex act, since all processes must occur in a certain sequence, which helps to mix the secretion of the different glands that make up the seminal fluid – to ensure normal functioning of spermatozoa.

The ejaculation center is located in the lumbar spinal cord. Certain parts of the brain also play a role.

Ejaculation and orgasm occur after a sharp increase in sexual arousal during penile stimulation (with frictions in the vagina or other stimulation).

Ejaculation begins with active muscle contraction of the vas deferens and occurs in two phases.

In the first phase, the seed is removed from the epididymis into the prostate of the urethra (urethra). In this phase, the seed presses on the back of the urethra, which causes a sensation of voluptuousness. According to V. Masters and V. Johnson, there is no orgasm as such yet, but there is only a feeling of its inevitability. This moment occurs 2–4 seconds before the ejaculate is ejected.

In the first phase, anticipating the onset of ejaculation, a man can learn to control ejaculation, restraining the onset of orgasm.

Delaying ejaculation is achieved in three ways – suspension of frictions or other stimulation of the penis, compression of the coronary rib of the penis when the penis is removed from the vagina, or by pressing at a certain point in the region of the penis root, which is possible without removing the penis of their vagina.

In the second phase, the seed is thrown out in the form of a mixture of various secrets of the genital glands – into the female genital organs or outward. This phase is reflex. If it begins, then it is impossible to suspend it.

Ejaculation occurs a few seconds after reaching the point of “ejaculatory inevitability”, as the passage of seminal fluid through the urethra requires a certain amount of time. When ejaculating, the bladder neck closes tightly. Thanks to this, the seed is pushed forward, and in addition, it prevents its mixing with urine.

Then there is the stage of ejaculation – there are rhythmic contractions of the prostate gland, muscles of the perineum and penis (which corresponds to the movement of the seed), at intervals of 0.8 seconds. After 3-4 penile contractions, the intervals between contractions increase, and their intensity gradually decreases.

Ejaculation can be so intense that in some men, seminal fluid erupts at a distance of 1 meter.

The release of male seminal fluid during intercourse is usually well felt by a woman. This can be a strong stimulation for the female vagina, and a woman can experience a strong orgasm, feeling the pulsation of the penis during ejaculation.

As sexologists write, although ejaculation is an involuntary act, that is, arising beyond the will of a man, but nevertheless, the brain has a certain effect on it. This is proved by the fact that ejaculation can occur with a purely mental arousal, without affecting the erogenous zone (penis). In addition, this is proved by the existence of the so-called cortically determined functional aspermatism – sexual intercourse with a certain woman never ends with ejaculation, regardless of the duration of frictions, and with another woman, ejaculation can be timely.

Sperm (synonyms – seminal fluid, ejaculate) – is a mixture of the secretion products of the male genital organs – the testes and accessory genital glands. The sperm of an adult male is a mucus-like, heterogeneous, opaque liquid with a characteristic odor. Its amount is individual and can be from 1–2 to 10 ml or more, and on average, from 3–3.5 ml. The ability of sperm to fertilize does not depend on its quantity.

The fertilizing ability of sperm is determined by the number of sperm in 1 ml of seminal fluid. Normally, this amount is between 60 and 120 million sperm. Moreover, living and motile sperm should be at least 70%. According to the World Health Organization, the lowest limit of the norm is 20 million sperm (sperm).

Sperm is a mature male reproductive cell. In a mature human sperm, the head, neck, body and tail, or flagellum, is isolated. The length of the sperm is 50-60 microns. In the sperm head is the nucleus, which carries the genetic information of a man. In the neck and body there are spiral threads that provide motor activity of the sperm.

The most characteristic property of a sperm is its motility. It is carried out by rotating around its own axis clockwise with the help of tail strokes. A sperm with normal motility moves against the fluid flow at a speed of 3 mm per minute.

A sperm exists in the vagina for 2.5 hours, and if it enters the cervix, then up to two days or more. Therefore, fertilization of a woman’s mature egg can occur even after two days or more after sexual intercourse, if the sperm has entered the uterus from the vagina.

At the anterior end of the sperm head there is an acrosome, which allows sperm to enter the female egg. In most cases, only one sperm can fertilize an egg. The sex of the unborn child depends on whether it contains the sex chromosome – X or Y. Sperm with the Y chromosome are called androderma, and with the X chromosome – gynospermia.

Sperm volume depends on the secretion of the accessory sex glands, which liquefy it and create favorable conditions for the life of sperm. In addition to sperm, sperm contains organic substances, trace elements, protein, amino acids, enzymes, glucose, citric acid and other elements that serve as a nutrient medium for sperm, ensure their survival and mobility in the female genital organs. Individual differences in sperm composition, color and amount are possible.

If the man had several sexual intercourse during the day, then in the third portion of the ejaculate the sperm disappear, and the seminal fluid is only the secret of the sex glands. Spermatozoa reappear in sperm only after 2-3 days of sexual rest.
