MAP test negative in men who have a healthy childbearing function. Problems with conception arise in many modern couples. This is due to various negative environmental factors and pathological habits. In many cases, the cause of infertility is in the female body. But sometimes this problem arises because of a man.
Causes of Infertility
Male infertility has a different character. The main reason is considered insufficient number of mobile spermatozoa in seminal fluid. This can be identified by passing a special analysis - spermogram. In this analysis, the specialist determines the percentage of mobile spermatozoa having the correct shape.
If the spermatozoa are healthy, it is necessary to establish a cervical factor. In this case, the death of spermatozoa in the cervix is observed. This phenomenon arises from the acidity of the microflora of the uterus.
This type of infertility is eliminated using local medications. Which change the pH of the microflora before sexual intercourse. After passing the neck of the sperm retain viability.
In rare cases, there is a problem with diagnosing male infertility. In this case, it is necessary to determine the autoimmune condition.
This system is necessary for a person to maintain the protective properties of the body. The autoimmune system helps the body to quickly and effectively fight off various pathogens and cells.
Protection is carried out by special substances - antibodies. For each foreign microorganism, the system produces certain antibodies. In some cases, autoimmune protection fails. In this case, the system attacks the body's own cells. When male infertility against the background of an autoimmune failure in the body, men produce antisperm antibodies. These cells attack spermatozoa and change their functions. Externally, such a sex cell has no obvious changes. In the laboratory study, an antibody is found on individual sections of the spermatozoon. It also causes autoimmune infertility.
How to determine the cause of infertility
To determine the cause of infertility, men take ejaculate. The liquid is carefully examined in the laboratory under a special microscope. It is necessary to determine the number of healthy cells, the presence of abnormal spermatozoa and pH sperm counts. This test does not make it possible to determine the presence of antisperm antibodies. For this, the MAP test is used.
MAP test allows you to determine the quantitative content of spermatozoa infected with antisperm antibodies. To do this, a drop of ejaculate is placed on the glass, which is divided into several sections. Each section contains a certain number of germ cells. The laboratory assistant counts all the cells. The total number of spermatozoa is 100% volume. The number of cells with antisperm antibodies is calculated from the total volume.
Decoding of the results of
Many patients can not independently decipher the results of the MAP test. To determine whether it is worth rejoicing or grieving, it is necessary to understand how to count it.
Laboratories give the results of MAP test in percentage terms. The percentage of each patient is different. Do not be alarmed if the MAP test showed results of up to 10%.This is the normal content of antisperm antibodies in the male body. Also, do not get upset at zero. In this case, the autoimmune system works just as well.
An alarm causes results from 10 to 50%.In this case, an additional MAP test is required. Such indicators may be erroneous due to an incorrect distribution of sperm by the secret of the ejaculate. In this case, you should pay attention to the total volume of ejaculate. Take a few drops of fluid, which are investigated for quantitative indicators. If the results of the study are confirmed, the IDA test is also considered negative in this case. But it is necessary to monitor the condition of the autoimmune system. For this, the patient must undergo an MAP test every 6 months.
A positive MAP test is considered with results above 50%.In this case, the antispermal antibodies of a male exert a pernicious effect on most of the germ cells. In this case, a positive conception is minimized. To treat this disease, it is necessary to pass a survey with several specialists. Doctors will determine the causes of the violation of autoimmune protection and prescribe the necessary complex treatment.
Preparation for the analysis of the
MAP test is considered accurate only if certain rules are followed. A man must fulfill the following requirements before collecting seminal fluid analysis:
- Sexual abstinence;
- Elimination of bad habits;
- Refusal of various therapies.
The main requirement for passing the MAP test is sexual abstinence. A man should avoid sexual contact within a week. During this period, the body will accumulate the necessary number of spermatozoa. This rule is necessary for the precise determination of the percentage of antisperm antibodies.
Male sex cells have a certain duration of viability. For the correct MAP test, the liquid must contain both young cells and old ones. The average cell viability is 3-5 days. At the same time, new spermatozoa are constantly produced in the body. To accumulate the required number of cells, it takes 5-7 days. For this reason, abstinence is recommended. If it does not, the MAP test must be retaken.
For the MAP test, it is necessary to follow such a rule as eliminating bad habits. Particular attention should be paid to the use of alcohol-containing beverages. Such liquids contain alcohol in various amounts. Alcohol molecules have a harmful effect on the sex cells. The intake of alcohol leads to a decrease in the content of spermatozoa in the seminal fluid. At this test result is considered invalid.
If a man undergoes any medication treatment during the study, their effect on the sex cells should be established. Some drugs cause a change in the qualitative and quantitative characteristics of the seminal fluid. Activation of the autoimmune system against drug therapy may also occur. Determine whether there is such an effect for each particular drug, only a doctor can. It is not recommended to refuse treatment on your own. In some cases, this can lead to additional health problems.
Compliance with these rules allows you to obtain accurate MAP test results. If the man did not prepare, the analysis must be retaken. The
MAP test is considered an effective method of determining autoimmune infertility in men. Only this kind of research makes it possible to pinpoint the cause of childlessness in a young family. If the MAP test for a man showed a negative result, you should look for other causes of infertility.
