Changes sperm

Oligospermia. A reduced amount of semen released during sexual intercourse (in the norm of about 5 ml, 1 ml - 60-120 million spermatozoa), may be physiological phenomenon of a temporary nature, such as repeated sexual acts, or permanent - male old age. Pathological oligospermia depends mostly from Scar changes in the testicles, prostate, seminal vesicles, or in the sperm ways due to inflammation.
Aspermia (Aspirmatic). The absence of ejaculation when normally proceeding intercourse may depend on a scar narrowing of the urethra or excretory ducts of the prostate and seminal vesicles, often after gonorrheal inflammation posterior urethra. In the first case, the sperm cannot pass through a narrow place urethra and flows retrograde to the bladder, the second - content seminal vesicles and follicles prostate may not stand out in the urethra. There is also aspermia because of the lack of excitability of Central ejaculation in the spinal cord, with organic diseases of the nervous system or during a temporary depletion on the grounds of sexual excesses, alcoholism, drug use.
Azoospermia. The absence of sperm sperm occurs most often in people who have had bilateral inflammation of the epididymis, and can result in scarring that hamper the passage of sperm through the epididymis in the tubes that carry sperm. In other cases, azoospermia depends on bilateral cryptorchidism, congenital absence or underdevelopment of the testicles, transferred inflammation or General intoxication of an organism.
Aspermia and azoospermia cause sterility men (impotentio generandi), i.e. the inability to fertilize while preserving the ability to have sex (potentio coeundi).
Necrosphere. Sterility may depend not only on the absence in the sperm sperm, but also from changes in their quality. Here first of all is the loss of sperm inherent mobility - necrosphere. If the number of still sperm exceed 20% of the total number of them, you should consider that there sterility.
Cause of necrosphere can be functional failure of the testicles, congenital or acquired. In the result of inflammation of the prostate alkaline reaction of her secret becomes acidic, because of this secret loses the ability to cause active sperm motility.
For the evaluation of potentio generandi men it is important to consider not only the availability and mobility of sperm, but the spermiogram in General, i.e. the total number of sperm, the ratio of mobile and fixed and pathological forms.
To change the shape of the sperm are deformities of the head, neck and tail. There are about 50 types of heads. The number of normal sperm should be 80-85%. The presence of 25% or more of pathological forms head points to sterility.
Microscopically, you can explore the sperm ejected in a glass vessel through Masturbation or interrupted sexual intercourse (coitus interruptus). A drop of sperm under cover glass to explore the number, mobility, the shape of the sperm, the presence of lipoid grains and pathological admixtures.
Hemospermia and piodermia. Distinguish between the true and the false hemospermia and biosphere. At first all the cum mixed with blood or pus, which indicates inflammation (particularly tuberculosis), neoplasm, stones, prostate, or seminal vesicles; at the second - blood or pus mixed to cum in a separate thread that indicates inflammation in the back of the urethra.
