Oligoastenoteratozoospermiya - a number of violations, causes a decrease in the concentration of spermatozoa (oligozoospermia), decreased
to less than 50% full of sperm (teratozoospermia), reduced to less than 50% of sperm moving forward (asthenozoospermia).
Male infertility can be caused by various factors and is divided into mixed, secretory, immunological, excretory, idiopathic forms. Approximately one-third of all causes of infertility in men is caused by idiopathic oligoastenoteratozoospermiey.
Occurrence oligoastenoteratozoospermii caused by internal disturbances in the body, provoking infertility. So, an important role is played by an anomaly in the development of the reproductive system, including hypoplasia or aplasia of the testicles and their appendages. Often, the cause becomes oligoastenoteratozoospermii cryptorchidism, disruptions to the adrenal gland, thyroid gland, diabetes, liver and kidney disease, dropsy of testicular membranes. If varicose veins observed in mixed cord, it can cause disturbances in the normal operation of the reproductive system in men.
A major role in the development of play oligoastenoteratozoospermii infectious diseases with viral or bacterial origin (mumps, tuberculosis, syphilis, typhoid). Equally important in the environment play a residence and safe profession. For example, the negative effects on the work environment has an electromagnetic field of high intensity and frequency of ionizing radiation, work in high ambient temperature, etc. Great harm is done if the men with mercury, pesticides, lead, herbicides, alkalis, acids, arsenic, cadmium and zinc.
Another common cause is oligoastenoteratozoospermii unhealthy lifestyles, which are extremely negative impact on men's health. For example, a devastating effect on the body has drug use, smoking, excessive consumption of alcohol, antidepressants, tranquilizers.
Note that oligoastenoteratozoospermiya no external clinical symptoms, disease diagnosis however presents certain difficulties.
Diagnosis oligoastenoteratozoospermii is based on the analysis of data semen. Actually, the main source of semen, by which you can identify deviations from the norm. According to the recommendations of the World Health Organization, there are certain criteria for normal sperm are used in clinical practice worldwide.
this analysis - the procedure is very responsible, and is carried out only in specialized clinics with all the necessary conditions. Semen analysis - the analysis of a very complex, requires high professional laboratory doctors. Spending should be very careful.
To the result was as accurate as possible, it is recommended to take spermogrammu several times, as the results of the analysis can influence a large number of factors.
Today the world medicine has made significant progress in the treatment of oligoastenoteratozoospermii. This success is largely due to the implementation in practice of intracytoplasmic sperm injection (ICSI). This advanced technique allows men to have offspring even at such a distressing diagnosis as teratozoostpermiya, oligozoospermia and asthenozoospermia, as is well known, oligoastenoteratozoospermiya is a combination of all three indicators of violations.
ICSI method means that a single sperm penetrates ooplasm previously indicated by morphological characters. Today the ICSI technique is based on IVF and PE and is considered one of the most effective ways of fertilization, so widely used throughout the world.
Unlike IVF where fertilization success depends on having a large amount of sperm in the ICSI method, only one sperm is injected. This proves that the successful fertilization sperm count does not matter. However, when choosing a sperm pay attention to his mobility and normal morphology, which is estimated by the criterion of Kruger.
The parameters of treatment success oligoastenoteratozoospermii men using ICSI is the presence in his testicle, or ejaculate mobile and healthy sperm, and women - the quality of oocytes.
