Section of the benefits of male ejaculation

Men during sexual intercourse, first by central excited, cause the penis are filled with blood and erectile, through the friction to a certain degree of stimulation, cause ejaculation.

Ejaculation is a reflection process. The first is from testicular small tube contraction of the output, then head of epididymis, body, then is the tail shrinkage epididymis. Sperm vasectomy and flooding into the vasectomy pot belly, and finally the prostate gland emptying of the seminal vesicle, sperm and seminal plasma flooding into the urethra. As bulbocavernosus muscle and siatic sponge body muscle contraction, but also by the closure of the bladder neck, stop semen retrograde into bladder, and make the semen from urethra with rhythm, the injection.

Generally think ejaculation had seven process strong, the rhythmic contraction action. We can artificially build ejaculation process is divided into two sections, the first three for a period, the main part of the semen from prostate; The rest for a few, mainly from the seminal vesicle glands. Generally speaking, the first part of the sperm density, whether in the activities, mobility, survival rate, or the stability of the film is much higher than the second part. According to statistics, 89% of men first part of the second part than sperm count, two parts the same 5%, and the second part is the first part of the greater than 6%.

Segmentation method in the treatment of male infertility ejaculation a clinical significance. If patients sperm count and activities low rate, or at the same time with semen too sticky, semen is too much, can be in women with subsection ejaculation sex oviposit period method. When the first paragraph sperm injection immediately after the penis out from inside vagina, make the rest of the semen to shoot on the outside, this can avoid the seminal vesicle gland secretion dilution semen, so as to ensure high density, high quality, high energy sperm in vagina, improve the ability of conception. In "artificial insemination" and "test-tube baby" in practice, segmentation also become a regular ejaculation the steps. Will the first paragraph semen after processing, selected high energy sperm, send into the uterus or used for in vitro fertilization.

In the clinical biochemistry examines, can also according to the order of sperm injection were collecting four to six parts, the first part of main from prostate liquid, most active acidic phosphatase; The last part is the seminal vesicle gland liquid, including prostaglandin and fructose are the highest. Through the determination of these special enzymes or material can understand the function of the attached. The inspection method can also be used to study the physiological activities when ejaculation. Some people because neurological problems, ejaculation process happens disorder, sperm is not main and prostate liquid injection together, but with the seminal vesicle gland with liquid injection, sperm activity below normal. It could also be a cause infertility.
