Testicular: the main function is to produce sperm and secretion of male hormone (testosterone). The former and egg fertilization combination, is the important material base breed, the latter is to maintain the male secondary sex characteristics important material. Testicular in early embryos is located in the abdominal cavity, accurately is located in the inguinal canal through ring place, later down gradually, to the 7 th months, testicular fast through the inguinal canal and drop to Yin Man, testicular over parts is locked. Testicular in fall to the process of the scrotum, can appear all sorts of abnormal conditions, such as membrane sudden closure or not scabbard atresia not completely, the scabbard membrane happened water, spermatic cyst, hernia, etc.; Such as incomplete and stop testicular descent in the peritoneal cavity or groin tube, called "the testicular descent", or called "cryptorchidism was"; Such as testosterone, not to fall in the scrotum and migration to the perineal, penis root, shares in the department, called "testicular ectopic". Testicular position is not normal, it affect sperm production and the development of quality and quantity, go against fertility.
Epididymis: the main function is to promote the development and mature sperm, and storage and transport sperm. Testicular sperm from fine fine tube produced music, but the lack of ability to move, does not have the ability to bear children, still need to continue to development and mature, mainly in the stage of epididymis. Epididymis secrete a kind of mature sperm directly nurtured liquid, called epididymis liquid, the liquid high potassium phosphate, glycerin bile salts concentration, indican high concentration and ph enzymatic low, osmotic pressure high, less oxygen and carbon dioxide high. Generally speaking, epididymal storage about 70% of the sperm (2% is stored in the vasectomy) 5 ~ 25 days, in average, 12 days, than in other parts of the male genitalia of time is long. The epididymis sperm during sex, through the epididymis tube, suggesting the ejaculation, pipe and urethral out of body. Sperm in the long-term if the epididymis discharge, the part is broken down and absorbed, gradually into the urethra of urine, so in adult men of urine when the examination, OuHuo can find sperm. When epididymis produce inflammation or other diseases, can affect sperm mature degree and against fertility.
Vas deferens: strong peristalsis ability, because wall muscle is very thick, the main function is to transport and discharge sperm. In the ejaculation, sympathetic not sad the release of a large class are epinephrine material, make each other and strong coordination vasectomy happen contraction, sperm to fine Nao quickly will drain pipe, tube in the urinary tract and ejaculation. When vasectomy produce inflammation or clogged, sperm cannot eduction male infertility cause, by the same token, when the male birth control, it is feasible to vasectomy ligation operation.
The seminal vesicle: the main function is to secrete a kind of mucous, neither produce sperm, also do not store sperm. The seminal vesicle a mucus, phosphoric acid secretion with bile salts, globulin, citric acid and alkaline nucleoside sugar etc colloidal liquid, mainly ning Chuan acid (125 mg / 100 ml) and a nucleoside sugar (315 mg / 100 ml), they are the main components of the semen (about 50% ~ 80%), ejaculation in liquid discharge after when the prostate, sugar in a nucleoside after ejaculation provide the main energy essence of life activities; Two seminal vesicle secretion containing solidify enzyme, main effect is when sperm into the feminine vagina after, can make semen in vagina keep short solidification, prevent flows from the vagina, increase the chance conception. When sentiment capsule inflammation in the body or poor health, will influence the seminal vesicle secrete a function, reduce nucleoside sugar content, weaken sperm activity. Even cause death sperm, and cause a male infertility.
Spermatic: main function is to testis and epididymis suspension in within the scrotum, testis and epididymis protection is not damaged, and as the temperature change and shrinkage or relaxation, make the testicles to adapt to the external environment, keep the best condition of sperm production and has not optional activity testicles (cremaster muscle). When trauma or caused by infection spermatic lesions that can damage the testis and epididymis the particularity of blood supply, and the influence of the testis and epididymis function; When spermatic lymphatic clogging, also can cause testis and epididymis function decline; When varicocele, spermatic vein blood stasis in sluggish, testicles will influence the local blood circulation, the blood oxygen decrease in the testicles, ph change, cause increased sperm deformity, sperm population decline, sperm motility refuse, so to say, spermatic is the "lifeline" testicles.
Ejaculation tube: the main function is to ejaculation, muscle a wall of ejaculation rich, with a strong contraction force, help sperm injection, and pure tube when in a checkered urethra in its mouth, is small and narrow. In order to ensure that the ejaculation due pressure, another �� through small openings in semen, there seems to be a "squeeze" feeling, neural reflex, caused a sense of ejaculation article, so as to achieve the sexual climax period.
Prostate: the major function is the secretion of the prostatic secretion, also is one of the components of the semen (about of semen 13 to 32%), amplification of the sperm, be helpful for sperm injection, prostate liquid in the seminal vesicle liquid after injection. Prostate liquid viscous liquid for ivory, a basic, each H / # t4 about 0. : ~ 2. O ml, contains more than blood of sodium, potassium, calcium ions, and a large number of zinc and magnesium cation, high, and outside �� also contain chlorine, bicarbonate, phosphate, arrested Chuan acid salt, amino acids, Chen, border, anionic, provide sperm activity of energy; Before 1 gland liquid contains either good or bad acid phosphorus sex enzyme, to keep men first:; Two sex card of development and mature; The prostate is a lot of liquid protein decomposing enzyme, such as fibrinolysis enzyme and hyaluronidase, make the semen liquefaction, promote the sperm in the sperm of free activities, and can dissolve the cervical tube in the mouth mucus plugs and egg with transparent, and promote the combination of sperm and egg and fertilized; Prostate partial alkaline, can the feminine vagina secretion and the acid, and) by sperm in the vagina to survive. Either good or bad; the liquefaction before glands factors and the seminal vesicle the solidified the role of liquid factor the complete opposite, first after solidification liquefaction, organic. = close, help to the improvement of the performance of fertility. Prostate were sex Cambodia contractions of 1 when, will open the prostatic secretion: enter the urethra. When prostate inflammation in or other diseases, the liquid secretion and influence prostate discharge, go against fertilization, urethral ball gland: the major function is transparent with a small amount of the secretion of a gray mucin mucous, is also part of the semen. Urethral ball glands in the whole wide distribution urethra, when your penis when, urethral ball gland suffers extruding, secrete a few transparent mucous, full of urinary tract mucous membrane surface, lubrication, be helpful for semen eduction.
Urethral: main function is excreting urine and semen, urine and semen is the common channel. In the urethra ball by the department has a pair of urethral ball glands, secrete a little liquid, is also part of the sperm, and at the same time, your penis intercourse first outflow urethral opening, lubricating the penis head, which is beneficial to the penis insertion vagina.
Scrotal: the main function is to adjust temperature, keeping them in a constant temperature environment (35 degrees or so). Scrotal skin thin and soft. Contains rich sweat glands and sebaceous glands, in cold, to carry on the scrotum contraction testicles to abdomen, with heat and improve the body temperature, in hot, scrotal relaxation that testicular descent, spin and distance of the abdomen, and secretion for heat loss in the scrotum sweat, testicular temperature drop. Testicular produce sperm and sperm in a mature process, need to be in 35 degrees or so in an environment temperature, the body temperature of 37.2 degrees or so, scrotal contraction heat preservation, relax cooling, therefore we can say, is the scrotum testicles "constant temperature box". When scrotal out of order, constant temperature environment from being broken, the generation and development of adverse sperm, affect sperm quality.
The penis: the major function is the urination, row semen and sex, sex is the main organ, the penis skin is extremely thin, under the skin does not have the fat, has the activity and the extension, the penis sponge body's blood sinus can attach into the blood, in asexual urge, the penis mian soft, in sex beam (when the penis sponge body of blood sinus blood inside the penis is increasing, swollen, add thick harden and erectile, when inflows of the blood and blood backflow of equal, the last; the penis head erect penis is not a little nervous, sexy is extremely strong, rich in sexual climax, due to the highly excited and central ejaculation ejaculation; 1 up. In the sex bunch of 1 under cannot erect penis IP or erection hardness is not enough, cannot intercourse activities, called "impotent", penile erectile abnormal or the penis deformity can cause sexual intercourse difficult.
