Necrospermia is a condition in which the viability of sperm after elimination from the body is low, and this type of condition often leads to infertility. Necrospermia is a very rare form of male infertility that occurs when all the sperm in a semen sample die, resulting in complete necrospermia. This type of disease has no symptomatic manifestations and is determined primarily by diagnosis. The onset of this disorder is relatively rare, and most of the time necrospermia diagnosed in the laboratory may be an error, caused because the man uses a lubricant that does not contain fertility while masturbating. This condition can be avoided by changing the type of lubricant used. It is also possible that the container used to collect the sperm was dirty. Semen samples should be collected in a dry, sterile cup. If the cup is contaminated, then anything in the cup could kill the sperm. But this is a relatively rare occurrence. In daily life patients may try to use condoms to get sperm, but there will be some condoms with materials that will kill the sperm. So it can cause all of them to die. The cause of dead sperm is not completely determined, but there are factors that can trigger it. Such as unhealthy reproductive tract of men or testicular problems. All of them can lead to this type of disease.
