Often, the representatives of the stronger sex who are in fertile age, the doctor makes a diagnosis - astenozoospermia. This male ailment is directly related to infertility. Next, consider what kind of disease, its causes and treatment, as well as the relationship of asthenozoospermia and conception.

What is this disease?

What it is?The term characterizes a certain state of sperm, in which there is a decrease in the number of mobile spermatozoa, coupled with their motor activity.


Astenozoospermia is diagnosed by a special analysis - spermogram - and associated diagnostics for the presence of infectious diseases and ultrasound (clarifies the causes of pathology).

It should be noted that normal sperm counts are: volume - no less than 2 ml, strength sperm in 1 ml of ejaculate - not less than 20 million, while more than 50% of their number should be normal move.

There are several degrees of asthenozoospermia:

  • 1 degree of disease (also called insignificant) - the total number of mobile spermatozoa - at least half (50%) of the total number;
  • asthenozoospermia 2 degrees (another name - moderate) - the number of mobile spermatozoa in the seminal fluid reaches from 30 to 40%;
  • pathological process - asthenozoospermia 3 degrees - less than 30% of mobile spermatozoa are detected in the seminal fluid.

Causes of pathology development

The causes of asthenozoospermia are very different. These include:

  1. Violation of the morphology of spermatozoa caused by genetic modifications of the structure of the flagellum or mitochondria. This reason is considered to be the most important in the appearance in the spermogram of indications for asthenozoospermia.
  2. Bonding of spermatozoa.
  3. Detection of bacteria in seminal fluid, which causes a significant decrease in motor activity of spermatozoa.
  4. Changes concerning the composition of seminal fluid: this change may be a decrease in the level of fructose, which acts as a source of sperm energy.
  5. Acidification of the sperm liquid, the medium of which, under the normal state of affairs, must be alkaline.
  6. The harmful effect of toxins (alcohol, smoking, drugs and others).
  7. The increased viscosity of the ejaculate also refers to the causes of the disease.

Is it possible to plan a pregnancy with a similar diagnosis?

This will be largely determined by the degree of severity of asthenozoospermia. The presence of single, but reached maturity and sufficiently mobile spermatozoa gives grounds for the appearance of pregnancy. The less the degree of disease, the greater the probability of pregnancy.

Interdependence of asthenozoospermia with other abnormalities in the spermogram

The obtained data of spermogram is compared on the relationship of this pathology and teratozoospermia. The latter is considered a violation, in which more than 50% of spermatozoa with pathological forms are found in the ejaculate. These are the forms in which a sperm can have an enlarged head or an impaired neck (deformed and thickened). If a pathogenically irregular form of spermatozoon is detected in the seminal fluid, the married couple should be temporarily to postpone the planning of pregnancy, the husband must always undergo asteno- and teratozoospermia treatment andrologist.

Often the disease adjoins and with piospermia. Piospermia is a signal that the number of leukocytes in the sperm exceeds the critical number. The norm, when 1 ml of sperm liquid contains 1 million leukocytes, represented by neutrophils.

Piospermia is a consequence of the inflammatory process: prostatitis, orchitis, epididymitis, vesiculitis. It is important to take into account the fact that the presence of piospermia is the basis for the development of asthenozoospermia, this greatly reduces the chances of a pregnancy. With piospermia, sperm seeding is shown to determine the causative agent of the infectious process and subsequent treatment.


What is the treatment of asthenozoospermia?

With this diagnosis, there is a legitimate question, but how to treat this disease? It should be noted that in 90-95% of the cases of such a diagnosis of man astenozoospermia very well lends itself to corrective measures. Especially if the pathology is still at a moderate stage or insignificant.

The choice of tactics for conservative therapy will largely depend on those factors that were the primary cause of reduced motility of spermatozoa.

For example, minor asthenozoospermia (in 1 degree) is eliminated by reviewing and reorganizing one's lifestyle: exclude smoking and strong drinks; pick up an active sport for yourself and deal with it; minimize the amount of thermal procedures in the sauna, bath, in the hot tub; change the place of work if it relates to the effects on the body of heavy metals and radiation.

In the vast majority of cases, the elimination of asthenozoospermia of 2 and 3 severity is accompanied by antibiotic therapy with concomitant STIs, the adoption of vitamin-mineral complexes, immunomodulating drugs, physical therapy visits, massage of the prostate.



Surgical intervention for asthenozoospermia can be prescribed when the cause of the disease is varicocele. If the necessary therapeutic effect from the above actions is not achieved, the doctor prescribes artificial insemination, ICSI, IVF.

In any case, asthenozoospermia is treated, for this it is only necessary to establish precisely the cause of male infertility.

And only treatment under an individual scheme can guarantee a favorable prognosis.
