What causes azoospermia, necrospermia and male infertility?

Date:2011-11-19 click:

Prostatitis, orchitis and seminal vesiculitis lead to obstructive azoospermia, necrospermia and male infertility.

 
Causes of necrospermia, oligospermia:
 
The bacteria in the urethra will always enter prostate, spermary, deferent duct, epididymis and testicle via ejaculation, which can lead to inflammatory pathological changes, and finally result in prostatitis, seminal vesiculitis, deferentitis, epididymitis and so on.
 
1) When the bacteria reproduce in the tractus genitalis, there are some hazardous substances excreted to damage the sperms.
 
2) The bacterial reproduction in the tractus genitalis consumes large quantity of nutriment, which damages sperm’s living environment and the sperms will die due to lack of nutrition.which can lead to inflammatory pathological changes, and finally result in prostatitis, seminal vesiculitis, deferentitis, epididymitis and so on. 
 
3) The bacteria excrete large quantity of acid substances in the tractus genitalis, which will reduce the PH value of male tractus genitalis, and cause acid intoxication to the sperms.
 
Azoospermia, suffers from which a man's sperm activity ration is zero, is one kind of male infertility. The testis's producing no sperm or the prostatitis, epididymitis, seminal vesiculitis lead to edema and obstruction of ductus ejaculatorius, which influence spermiation and leads to obstructive azoospermia.
 
Prostatitis, seminal vesiculitis lead to necrospermia, oligospermia: Sperm is produced in convoluted tubule. Under the microscope, the sperm looks like a tadpole; when the dead sperms are over 50% of the total, it will cause infecundity, which in medical is called necrospermia.
 
The sperms are produced in the convoluted tubule of the testis and enter the epididymis first, and enter the spermary through deferent duct, and the fluid of seminal vesicle excreted in the seminal vesicle contains the essential nutrient substances for the living of sperms.
