What the male reproductive organs function
Posted by mimimi on November 3, 2008 in Venereal Disease
Testicular: The main function is to produce sperm and secretion of male hormone (testosterone). The former combined with eggs and fertilized, breeding is an important material foundation for future generations, while the latter is to maintain male Second Sex Levy (deputy of the levy), an important material. Early in the testes in the embryo within the abdominal cavity, is accurate in the groin of the inner ring, gradually declined, to 7 months, the testis and fast through the groin to the Yam Man, the testosterone above the closed position. Testicular next to the scrotum in the process, there can be all kinds of anomalies, such as the sheath process is not completely closed or not closed, stagnant water in a sheath, the spermatic cord cyst, hernia, etc., if not completely and testosterone decline in the abdominal cavity to stop Or in the groin, known as “incomplete testicular decline”, or “cryptorchid” such as testosterone in the fall Weizhi scrotum and migration to the perineum, the roots of the penis, the Department of shares, etc., known as “testicular ectopic . ” The location of the abnormal testis, the impact on sperm production and development of quality and quantity is not conducive to childbearing. Epididymis: The main function is to promote growth and mature sperm and the sperm storage and transport. Qu sperm from the testes of a small fine, but the lack of ability, do not have the ability to bear children, it is also necessary to continue the development and maturity, this stage mainly in the epididymis within. Secretion of a direct Epididymis nurtured mature sperm liquid, liquid known as the epididymis, the liquid potassium, glycerol phosphate bile salt concentration, glucosidase high concentration, low acidity, high osmotic pressure, the less oxygen, carbon dioxide high. Generally speaking, the epididymis storage of about 70% of the sperm (2% stored in the vas deferens) 5 to 25 days, an average of 12 days, than in other parts of the male genitalia of a long time. Sperm in the epididymis of intercourse, through the epididymis, the vas deferens, and the urethra She Jingguan from in vitro. If the sperm in the epididymis from under the long-term, part of the decomposition of absorption, some gradually enter the urine from the urethra, in the men’s urine checks, or even sperm can be found. When the epididymis inflammation or other disease, can affect the level of mature sperm and not conducive to childbearing. Vas deferens: a strong movement, and is due to thick muscle wall, the main function is to transport and excretion of sperm. In ejaculation, quietly sympathetic to release a large number of categories are adrenergic substances, the vas deferens in co-ordination and a strong contraction, the sperm will be fine to the rapid excretion of Nao, She Jingguan and in the urethra. When the vas deferens inflammation or blockage, the sperm can not result from male infertility, the same token, when the male birth control, can also visit ligation of the vas deferens. Seminal vesicle: The main function is a kind of mucus secretion, neither produce sperm or sperm storage. Secretions of mucus a seminal vesicle, phosphoric acid bile salt, globulin, citric acid and alkaline glycosides, such as colloidal liquid sugar, which is mainly Ning Chuan acid (125 mg/100ml) and glycoside sugar (315 mg/100ml), they are semen The main component of the (about 50% to 80%), ejaculation fluid in the prostate after discharge, after ejaculation glycosides sugar in a fine to provide the main energy; secretions two seminal vesicle with coagulase, a major role when the semen radio After the female vagina, semen in the vagina to keep short-term coagulation to prevent the outflow from the vagina, increase opportunities for pregnancy. When the situation capsule inflammation or physical ill health, the impact of the seminal vesicle secretion, glycosides reduced sugar content, reduced sperm activity. Even lead to death sperm, the result of male infertility. Spermatic cord: The main function is to be suspended in the testis and epididymis of the scrotum, the testis and epididymis protection from injury, as the temperature changes in systolic or relaxation, the testis to the external environment, and maintain sperm produced the best conditions The testis with involuntary activities (cremaster). When the injury or infection caused spermatic cord lesions, the testis and epididymis can damage the blood supply to the special nature and impact of the testis and epididymis function when the spermatic cord in the lymphatic blockage, it can cause dysfunction testis and epididymis when Of varicocele, the spermatic cord vein blood stasis, the impact of testicular local blood circulation, resulting in reduced oxygen in the testes, pH change, resulting in increased abnormal sperm, the sperm count decline in sperm activity decreased, so that fine Cable is the testis the “lifeline.” She Jingguan: The main function is to ejaculation, muscle wall ejaculation rich, with a strong contraction, to help sperm injection, at the same time, Qiao Jing of the urethra at the opening Ba, both small and narrow. To ensure the proper pressure ejaculation, semen through small openings on the other hand, there seems to be a “squeezed out” a sense of reflection through the nerve, to ejaculation caused the euphoria, to achieve orgasm period. Prostate: The main function is secreted by the prostate, is also one of the components of the semen (about semen from 13 to 32 per cent), the amplification of the semen and is conducive to sperm injection, prostatic fluid in the seminal vesicle End of the injection. Milky white liquid for prostate viscous liquid, a basic per H / # t4 about 0. : 1-2. O ml, containing more than the blood of sodium, potassium, calcium, and a large number of zinc, magnesium cation, Venturi, but also contains chlorine, bicarbonate, phosphate, arrests Chuan Salts, amino acids, Chen , And so on the occasion of anions, provided the sperm of energy; before the loser of a gland also contains phosphorus acid of the enzyme, in order to maintain male section: the second card of the development and maturity; prostatic fluid also contains a lot of the decomposition of protein, such as fibrin And the dissolution of hyaluronidase, liquefied semen, sperm in the semen in the promotion of free activities, and can dissolve in the mouth of the cervical mucus and eggs bolt with a transparent, and promote the combination of sperm and eggs and fertilized; prostate partial alkaline, And women can be in the acidic vaginal secretions, and) in the vagina sperm survival. Before loser] in the gland and seminal vesicle of liquefied factor in the coagulation factor in exactly the opposite effect, solidified after the first liquefaction, organic. = Unity and contribute to the improvement of reproductive performance. Prostate sexual Cambodia can be a shock when the contraction of the prostate will be demolished: the urethra. When prostate inflammation or other diseases, the impact of the prostatic fluid secretion and excretion, not conducive to fertilization, the ball urethral gland: The main function of the secretion of a small amount of slightly off-white with a transparent mucin mucus, is also an integral part of semen. – Urethral gland widely distributed throughout the urethra, when penile erection, urethra ball squeezed by the gland, a small transparent mucus secretion,urethra mucosal surface, from lubrication and is conducive to the discharge of semen. Urethra: The main function is to excretion of urine and semen, urine and semen is a common channel. In the urethral bulb next to a pair of ball urethral gland, a small amount of liquid secretion is also an integral part of semen, at the same time, in penile erection for intercourse when I first outflow urethra, lubricating the penis head, is conducive to the penis into the vagina. Scrotum: The main function is to regulate the temperature, maintaining a constant temperature of testicular environment (35 degrees). Scrotal skin thin and soft. Rich in sweat glands and sebaceous gland, in the cold, the scrotum to testicular shrinkage, to close the abdomen, using body heat and raise the temperature in very hot, so that testosterone decline in the scrotum relaxation, and lengthen the distance between the abdomen and scrotum to facilitate secretion of sweat In the heat dissipation so that the testicular temperature dropped. Testes produce sperm and the sperm maturation process, the needs of about 35 degrees in temperature environment, the body temperature of 37.2 degrees, the scrotum insulation contraction, relaxation, cooling, it can be said, is testosterone scrotum “incubators.” When the scrotum of defects, damage the environment temperature, the adverse development and the formation of sperm and affect sperm quality. Penis: The main function is to urinate, Pai semen and sexual intercourse, sexual intercourse is the main organ, the penis skin extremely thin, not fat under the skin, with activity and stretching, the sinusoids penis can be attached to the blood, in the Clones Impulse, the penis foam, and beam (stimulated when the penis within the sinusoids blood increased, while the penis enlargement and thickening and hardening erection, when the flow of blood and the blood returning the same time, Priapism; penis Not just the head of rich, very sexy, culminating in sexual intercourse, ejaculation hub because of the high degree of excitement and 1 from ejaculation. Beam of a shock in the penile erection or not enough hardness of erection, sexual intercourse can not be carried out activities that “Impotence”, erectile penile deformity or abnormality can cause sexual difficulties.
