The MAP test is negative: that is the norm

The MAP test is negative at the man that handed over the analysis on the possibility of having children means that his genital function all right.

This test is most commonly prescribed for those couples who can not conceive a child for a long time.

In addition to the typical physiological infertility, problems with conception arise against fatigue and nervosa, harmful work and malnutrition, the presence of bad habits and other factors environment.

diagnostic measures

The most common cause of male infertility is considered insufficient amount of active sperm in a semen able to fertilize the egg.

Determine the ability of the body helps a special analysis called semen.

In this analysis, the doctor can accurately determine the number of active sperm in the ejaculate, able to conceive and then to assess the possibility of fertilization.

If the analysis shows that the sperm are healthy, also take into account the "cervical factor" - the number of sperm that are killed in the cervix, not reaching the egg because of the acid microflora.

Such infertility embodiment the pair most often treated with medications that promote change the acidic environment of the uterus microflora of possible conception, longer-lasting vitality spermatozoa.

Why there is male infertility

Rarely, but it also happens that the causes of male infertility is very difficult to diagnose. Then the doctor will need to determine the patient's autoimmune condition.

This is a special system that supports the human body's protective properties and helps him to quickly deal with viruses and microbes.

Such protection is carried out special cells - antibodies and the system for each virus or infection produces specific antibodies.

When the body fails such protection, the antibodies start to destroy not harmful microbes and family healthy and necessary cells of its own body.

A man of such failure may be the cause of anti-sperm antibodies. These cells are then "attack" on the sperm and alter their structure and function.

Externally on the cage is not noticeable of these changes, but laboratory tests can indicate the presence of antibodies and as a consequence - an autoimmune infertility.

How to determine the cause of infertility

To a man as closely as possible the doctor was able to establish the cause of infertility, it is necessary to pass on the analysis of his sperm. The liquid investigate the presence and the number of healthy sperm cells, abnormal changes in the cells, acidity of the medium and other factors. In order to accurately determine the presence of sperm in the male sperm antibodies patient carried mar test.

What kind of analysis - MAP test

What does it mean analysis mar test? The MAP test is carrying out a semen analysis to most accurately determine the number of sperm that had hit the sperm antibodies. Spend it in the lab with the help of special equipment.

For this drop male seed was placed on a piece of glass, divided into several sections. In each of these sections previously placed a certain amount of gametes and their laboratory conducts count. Of the total amount thus determined as cells (in percentage terms) is not affected and is able to conceive.

How to decipher the test results

Usually patients can not afford on their own to decipher the results of the MAP test analysis. As accurately and professionally it can only make a specialist at the hospital. Negative men in March or positive test also did not say what is not a man without first consulting a doctor.

Normally, the analysis results are given in percentages and every man they will be individual to his body. If test parameters are specified up to 10%, then it is quite normal and permissible levels of antibodies in the body. If you are close to zero, then this is not a cause for concern.

If the test parameters in the range of 10 to 50 percent, then the man should turn and after the test to conduct another test.

Often MAP test shows is not quite accurate results due to the fact that the sperm in a laboratory properly distributed over the cells. Then you need to check the total amount of donated sperm and undergo re-analysis.

The MAP test is negative that a man does it mean? This means that with his health and sperm that's all right.

If the test is positive (50% and above), it means that sperm antibodies destroy most of the sperm and the couple can not conceive. With this test men need to see a doctor and undergo treatment.

How to prepare for the delivery of the analysis

IDA most accurate test performance can be achieved after proper and competent preparation for analysis.

Man before sperm is necessary to:

How to prepare for analysis

• a few days (5-7) to abstain from sexual relations.
• to give a few weeks prior to the analysis of bad habits, fried, spicy, fatty foods and preservatives.
• a few weeks before delivery of the analysis to stop the use of tablets and other drugs. If this is not possible, discuss the situation with the doctor.

The main requirements for conducting the test is considered sexual abstinence for about a week.

During this time the body needs to accumulate necessary for the analysis of sperm count. In addition, the male sex cells live for only a certain time - from 3 to 5 days, and to ensure that the test was as accurate as possible in the analysis should be to get young and old sperm.

It is important to remember that at the same time in a man's body is constantly producing new cells for sperm and their savings, too, need at least 5 days.

It is especially important for a week or even longer time before the test do not smoke or drink alcohol. Alcohol and other harmful substances can also destroy cells or sperm to reduce the total amount of sperm and distort results of the analysis.

If a man takes pills, hormonal agents, or other drugs, in the case of appointment of the MAP test, it is also necessary to discuss this point with the doctor. The specialist must establish how the drug influences on male germ cells and may decide to postpone treatment or to offer an alternative.

The use of some medications can cause male qualitative or quantitative changes in sperm. In addition, some drugs can specifically alter sperm cells or kill them. No need to decide what and when to take or not to further does not harm the body.

If you're preparing to pass the analysis, it is best to discuss all aspects with the doctor and then decide.

Compliance with this minimum list of rules will help to bring a man to the maximum accuracy of the analysis of its MAP test. If there is something on this list for some reason the patient is ignored, it will have to retake the test again.

brief conclusions

The MAP test - is one of the affordable and effective options to determine the presence of autoimmune infertility in men. After delivery of this analysis can determine the cause of infertility and appoint the most rapid and effective treatment. If the test result is negative but pregnancy does not occur, it is necessary to look for other causes of infertility.

A study of male infertility

The MAP test is negative men who have healthy reproductive function. Problems with conception occur in many modern couples. This is due to various negative environmental factors and pathological habits. In many cases, the cause of infertility lies in the female body. But sometimes a problem arises from the men.

Causes of infertility

Male infertility is a different character. The main reason is considered insufficient number of motile sperm in the semen. It can be detected by passing a special analysis - semen. In this assay specialist establishes the percentage of mobile spermatozoa having a regular shape.

If the sperm a man healthy, you need to install the cervical factor. In this case, a sperm death in the cervix. This phenomenon is due to the acidity of the uterus microflora.

Removal of this type of sterility is carried out using topical preparations. Which alter the microflora pH before intercourse. After passing through the cervix sperm remain viable.

This system is necessary for the person to maintain the protective properties of the organism. Autoimmune system helps the body quickly and effectively deal with a variety of pathogens and cells.

Protection is carried out by special substances - antibodies. For each system generates a foreign microorganism specific antibody. In some cases, a failure of the autoimmune defense. In this case, the system attacks the body's own cells.

When male infertility on the background of autoimmune failure in the male sperm antibodies are produced. These cells attack the sperm and alter their function. Outwardly, this sex cell has no obvious change.

In a laboratory study in certain areas detected sperm antibody. It is an autoimmune infertility.

How to determine the cause of infertility

To determine the cause of infertility in men is taken ejaculate. Liquid carefully studied in the laboratory under a special microscope. It is necessary to determine the number of healthy cells, the presence of abnormal sperm and semen pH indicators. Feet, this study is not to determine the presence of sperm antibodies. It uses the MAP test.

The MAP test makes it possible to establish the quantitative content of sperm affected sperm antibodies. For this drop ejaculate is placed on the glass, which is divided into several sections.

Each section contains a number of germ cells. Laboratory conducts count all cells. Total number of sperm is a 100% volume.

The number of cells with antisperm antibodies calculated on the total volume.

Decoding results

Many patients can not independently decode the MAP test results. To determine whether to be happy or upset, you need to understand how to read it.

Laboratory test results give IDA in percentage terms. The percentages in each patient is different. We should not be afraid if the MAP test results showed up to 10%. This is a normal content of antisperm antibodies in the male organism. Also, do not be upset, and at zero rates. In this case, the autoimmune system works too well.

Alarming of from 10 to 50%. In this case, you need to spend an additional MAP test. Such indicators may be erroneous due to improper distribution of sperm ejaculate secret. In this case, you should pay attention to the overall volume of ejaculate.

Take a few drops of liquid, which are investigated by quantitative indicators. If the results of the study are confirmed, the MAP test in this case is considered to be negative. But we need to monitor the condition of the autoimmune system.

To do this, the patient must take the MAP test every 6 months.

MAP is considered a positive test results when greater than 50%. In this case, the male sperm antibodies have a devastating effect on most of the germ cells.

The positive conception in this case is minimized. To treat this disease, you must be examined by several specialists.

Doctors determine the cause of autoimmune disorders Protection and appoint the necessary complex treatment.

Preparation for analysis

The MAP test is considered accurate only under certain rules. A man must meet the following requirements prior to collection of semen analysis:

• Sexual abstinence;
• Eliminating addictions;
• Refusal of different therapies.

The main requirement at the time of the test is IDA sexual abstinence. Men need to avoid sex for a week. During this period, the body will accumulate the required number of sperm. This rule necessary to accurately determine the percentage of sperm antibodies.

Sex male cells have a certain duration of viability. To correct the MAP test in the fluid must be kept as young cells, as well as the old. Average cell viability is 3-5 days.

In this case, the body is constantly produced new sperm. To gain the necessary number of cells, need 5-7 days. For this reason, we recommend abstinence.

If it is not carried out, it is necessary to re-take the MAP test.

For MAP test is necessary and the observance of such rules as the elimination of bad habits. Particular attention should be given to drink alcoholic beverages.

Such fluids contain alcohol in various amounts. alcohol molecules have a devastating effect on germ cells. Drinking alcohol entails reduction of sperm in the semen.

If this test result is considered invalid.

If the man during the trial goes any drug treatment, should establish their influence on the germ cells. Some drugs cause changes in qualitative and quantitative characteristics of the seminal fluid.

There may also be an autoimmune activation of the system on the background of drug therapy. Determine whether there is such an impact in each particular drug, the doctor can only. We do not recommend to refuse treatment.

In some cases this can lead to additional health problems.

The MAP test is considered an effective method for the determination of autoimmune infertility in men. Only this kind of study allows you to accurately determine the cause of infertility in a young family. If the MAP test a man showed a negative result, it is necessary to look for other causes of infertility.

MAP test: what is it and what is required?

Many couples are faced with a problem of conception. The reasons for this - the mass, but the most common - is infertility. Moreover, it can be both male and female. Standard analysis to confirm or refute male infertility semen analysis is considered. But there is another survey - the MAP test, which gives more detailed information on the state of men's health.

To determine the reproductive function of men in the first place appoint semen analysis. This survey, which allows to determine the status of semen, that is the presence of abnormal, immature sperm cells and pathogens. But it so happens that the results of the analysis are satisfactory, but the woman still can not get pregnant. In this case, it makes sense to pass the MAP test.

It is a study of the international level, which is based on the action of the immune system. Her feature - the fight against foreign organisms that enter the human body. Help her in this antibody - these proteins that attack pathological agents. Moreover, their antibodies exist for each agent.

If you violate the immune properties of certain proteins begin to destroy your own body. Some of these proteins are antisperm antibodies (ACAT). They are under certain conditions, adjacent to the sperm, limiting activity, reducing the ability of the latter to fertilize. On detection of such male gametes and directed MAP test.

Antibodies are generated against the male cells, there are several kinds.

• Immunoglobulin A. Is produced by mucous membranes, provides local reaction.
• Immunoglobulin M It formed in the first place, but it is destroyed within 2 weeks. Because of this, they can not be detected by the MAP test.
• Immunoglobulin G. It is present throughout life. On its discovery is based IDA diagnosis.
• ACAT They are located in semen, blood and cervical mucus. They form a shell around the sexual cells, thereby reducing its ability to fertilize.

The factors that cause such abnormalities include the following:

• infectious diseases;
• trauma organs of the reproductive system;
• diseases of the urogenital system;
• reasons unknown etiology;
• promiscuity;

Thus, this test is an immune response, the essence of which consists in the action of specific proteins.

In order to establish the difference between semen analysis and the MAP test it should be noted that the latter aims to identify the sperm is not able to conceive. Their appearance at the same time can not be changed, ie the male gamete that can fertilize an egg, it looks at the same normal.

Usual spermogramma shows only the presence of affected or immature cells. Also IDA-examination will help determine whether it is possible in principle pregnancy. It all depends on the percentage of the affected sperm to normal.

MAP testing - a more in-depth study of the causes of male infertility. The test is administered in the following cases:

• a couple can not conceive a child for a year, living a sexual life and do not take precautions;
• as a standard inspection before planning pregnancy;
• before carrying out the artificial insemination;
• after infections, which could adversely affect the reproductive system;

For accurate test results, you must follow some rules. They will help keep the sperm in a normal state. It is very important to the outcome of the investigation is not affected by external factors.

• A few days prior to the study action necessary to eliminate toxic compounds. This applies to men who work in the production of harmful working conditions. In this case, the analysis is better to take a vacation or after non-working days.
• During the week before the test need to comply with sexual abstinence. For proper diagnosis of sperm must contain both gametes young and mature. These cells are formed constantly. The average life span of 4-5 days. In order to able to accumulate in the body the sperm of different maturity, it will take about 7 days. Therefore, the need to restrict sex for a week. In addition, it will prevent semen biological traces partner. If the rule was not met, the report begins anew.
• before diagnosis limited alcohol intake. It contains alcohol, which destroys the reproductive cells. This will reduce the number of sperm in eyakulyante.
• If a man takes any medications, it may also affect the quality of sperm. Certain drugs cause both qualitative and quantitative changes in the seminal fluid. There is also the likelihood of activation of the immune system. Talk to your doctor about medication. Only he can give an opinion on the effects of a drug on the reproductive system. Groundless refusal of treatment may cause health problems.
• For 6-7 hours before diagnosis No smoking.
• before the examination normalize psycho-emotional state. Minimize exercise, plenty of rest and enough sleep.

Semen for research collected by masturbation into a sterile container. After collecting the material container is closed tightly fitting lid and sent to a lab not later than one hour, keeping it in the form of heat.

MAP test with semen analysis is considered the direct method. There is also an indirect method in which the investigated serum. Direct diagnosis is more common, as its most precise results. But in order to increase the efficiency of the test, it is recommended to use both methods. In this case, appears on the status and sperm cells, and the immune system.

MAP test, as well as other types of analysis, research in the laboratory. On a glass slide, divided into several parts, placed a drop of semen. Then here alternately added to latex beads solution and antisera thereto. If the surface of the sperm are sperm antibodies, they are glued to the beads.

Then calculate the percentage of infected cells. Their total number is taken as 100%. The number of sperm with spermatozoa antibodies is compared with normal. Then the percentage displayed. This figure is based interpretation of the results.

In addition, the test used to determine where exactly located immune cells. They can be localized in the head, neck, or sex cells of the tail. This indicates accumulation of beads in a particular area.

It should be remembered that the results of the analysis is to decipher a qualified specialist, although their own to do it too easy.

A negative result is considered normal or at values ​​from 0 to 10 percent. The number indicates the presence of sperm with sperm antibodies.

So many of them considered to be insufficient to prevent fertilization. The form can be fixed, that the result is negative.

It also means that the indicators are normal, that is in the semen is enough content full of germ cells.

A positive result is said when the value increased to 50% and above. A larger number of gametes thus inactivated. Chances of conceiving in this case, minimal. Plus, the positive test parameters may indicate the development of pathologies that also cause infertility:

• varicocele;
• testicular tumor;
• prostatitis;
• genital infections;
• the location of the testicles outside the scrotum;
• postoperative complications;
• traumatization of the genitals;
• obstruction of the vas deferens.

Weak positive result is obtained at values ​​of 25-50%. This means that the ability to fertilize is reduced, but not eliminated.

If the test performance is 100%, it comes to immune infertility. Conceiving naturally it is not possible, and the pair should have recourse to artificial insemination. Additional terms and conditions for this are:

• mobile number of germ cells (less than 0.5 million per 1 ml);
• custom sperm flagella;
• full number of gametes (below 1%).

The study is evaluated for antibodies two types: class IGA and IGG, as well as their location on the cell: tail, neck or head. The most dangerous is the concentration of ACAT in the head. All data are recorded in the results table.

2 class antibodies have different effects on the condition of the sperm and sperm. ACAT IGG increase the number of leucocytes in semen, which leads to disruption of its acidity and liquefaction.

IGA antibodies alter the structure of the most germ cell. This is the most numerous class of immunoglobulins, as it is not amenable to phagocytosis, but it is better to treat. their number is significantly reduced in semen appropriate therapy a couple of weeks.

According to the standards of the MAP test is carried out only in conjunction with semen analysis, since it is not considered an independent survey. It is made to clarify the data semen. For this purpose, one portion of the seminal fluid. The diagnosis is made the same specialist in one and the same institution.

In addition to the sperm with a specific antibody class IGA and IGG, MAR-test shows The following parameters of semen:

• volume (1.5 ml and up);
• consistency;
• color index;
• smell;
• pH: 7-8;
• the presence of leukocytes, erythrocytes, lipids;
• slimy impurities;
• bonding of sperm;
• activity, structure and the number of germ cells.

It is impossible to do research in the following cases:

• nekrozoospermiya - the number of non-viable sperm, more than half;
• kriptozoospermiya - decrease in the number of live sexual gametes in semen;
• azoospermia - in the sperm do not live germ cells are defined, so it is impossible to determine how they interact with the antibodies.

For women, also possible to conduct such an analysis. For this purpose, mucosal secretions uterine cervix. This material is used for direct analysis. For indirect method woman donates blood.

Also conduct post-coital test - study mucus after intercourse. Thus establish interaction of spermatozoa in mucous secretions. Such an investigation can be carried out in 2 ways.

1. Learn vaginal biomaterial on the mobility of sperm in it. Fence material produced within 10 hours after intercourse on days before the ovulation.
2. In the days before the release of an egg from the ovary, it is better in 1-2 days, collect the cervical mucus of women and male sperm. Examine the pin 2 of biological materials.

MAP test shows the number of normal, healthy germ cells, the antibody-bound, making them unable to conceive. From this figure depends on the diagnosis, which put a man.

It so happens that he is far from comforting. Immune infertility - a condition that is difficult to treat. Still, experts prescribe treatment of this condition.

To treat immunological infertility in several ways:

1. used hormonal treatments for several months. They have a suppressive effect on the immune system of men;
2. desensitizing therapy - reception antiallergic agents.

MAP testing is included in the list of mandatory surveys for couples who are planning a pregnancy. He also shows men who just want to check their reproductive health.

If you are ready to conceive, it is important that sperm retained their normal levels, and to please you test negative results. To this end, experts recommend to follow some rules:

• limit alcohol intake and smoking;
• prior to use of drugs, consult with your doctor to see if they will have effect on sexual function;
• dose exercise;
• Avoid high temperatures: refrain from visiting saunas, long exposure to the sun;

• spend more time in the fresh air;
• Adjust your diet - it should be as many useful products, but less - smoked, salty, spicy and particularly acute;
• refuse receiving glucocorticoids that inhibit the function of the reproductive system;
• Conception to better plan for the autumn, after the summer because the body is full of vitamins and energy;
• if the pregnancy is included in your plans, then sex is better to exercise in the morning, because at this time the most motile sperm;
• after affinity woman must not use for personal hygiene soap and other detergents: they change the acidity of the vaginal environment, as well as the structure of sperm cells and their activity.

MAP diagnostics - this particular study that reveals a man's ability to conceive naturally. It is important to properly prepare for the examination, that it did not disappoint false positive result. But even if you are not pleased with the performance, do not panic - you can adjust the revealed pathology.

Diagnosis of immunologic infertility MAP test

Semen - one of the main tests for suspected infertility in men. It shows the volume, viscosity, sperm and its color the PH, sperm count, motility and morphology (structure). But the result of semen only gives half the information about the possibility of the men have children.

Currently, much attention is paid to immunological infertility in men. For a more accurate diagnosis it is recommended to analyze - MAP test.

It is proved that the cause of male infertility are immunological antisperm antibodies which are formed on the sperm surface. Antisperm antibodies (immunoglobulins IgG, IgA and IgM,) are formed in the testes in males and their appendages.

Antigen to the antibody acts as the membrane of the sperm. If the antigen is not possible to neutralize antisperm antibodies then formed antispermalnyh casing which has an inhibiting effect on the spermatozoa in sperm surface.

MAP test to determine the presence or absence of sperm class G antibodies, which are formed on the sperm surface. If a man rents a normal semen analysis, sperm is covered with sperm antibodies in the analysis are considered as normal.

But in fact, they can not participate in fertilization. Using MAP test detected antibody titer, the percentage of sperm with antisperm antibodies to the total number of sperm.

Only thanks to the MAP test can determine the exact number of sperm capable of fertilization.

Indications for the MAP test analysis:

• presence of agglutination or aggregation of sperm (results spermiogram);
• reducing their motility and viability (based on spermiogram);
• infertility of the couple at normal performance standard examination;
• preparation for in vitro fertilization.

How is the MAP test

MAP test involves detection of sperm antibodies in semen and blood serum. These two MAP test (semen analysis and blood tests) are required as complementary.

Identification of antisperm antibodies in the blood is carried out by ELISA, and the special preparation before delivery of the blood test is required. For detection of antibodies in the semen ejaculate surrenders. The material collected in the same manner as for the analysis of semen.

Optimum is the simultaneous delivery of semen analysis, MAP test. Therefore, you can immediately explore a portion of the ejaculate for semen and MAP test.

Rules MAP test taking and preparation for study

By the semen analysis test and IDA should be carefully prepared:

• exclude sex (two to five days);
• stop taking alcohol and smoking for a week prior to the analysis, because alcohol and nicotine have a negative impact on sperm quality;
• discontinue medication one week before the delivery of the analysis;
• prohibited from visiting the baths and saunas;
• eliminate physical stress, avoid stressful situations, normalize sleep.

Sperm Preparation for semen analysis, the MAP test is conducted by masturbation.

Sterile container should be a screw cap, and must be delivered to the laboratory within an hour, keeping the material warm. MAP test results will be ready the next day.

To MAP test results were more accurate, it is recommended to carry out a study 2 times with an interval of two weeks.

MAP test transcript

MAP test - the norm, if the analysis of the men have been identified sperm with sperm antibodies. MAR-test is negative if the number of sperm coated antisperm antibodies does not exceed 50%. This, too, can be regarded as the MAP test - the norm.

MAP test is positive if the number of motile sperm, sperm antibodies covered, more than 50%. MAP-positive test indicates the likelihood of immunological infertility in men. When interpreting MAP recorded test space fixation antisperm antibodies.

The head of the sperm is the most unfavorable spot fixing.

What does the MAP test 100%

With this result, very low probability of pregnancy in women naturally from the surveyed men. Usually, when the results of the MAP test 100% recommend the use of the couple IVF-ICSI. When IDA assay 50-80% frequency of fertilization IVF decreases as the exponent MAP test 100% decreases sharply. In this regard, when Mar- test is 100% justified IVF-ICSI.

The indications for IVF-ICSI procedure except MAP test 100%, is:

• less than 500 000 motile sperm in the ejaculate;
• violation of sperm motility;
• abnormal acrosome in spermatozoa;
• less than 1% of normal sperm morphology .;

For many the question arises, where to pass the MAP test? This analysis is carried out in many laboratories. As an alternative, we propose to pass the MAP test invitro, an independent laboratory, which is a leader in the Russian laboratory market.

It is a network of high-tech laboratories in the cities of Moscow, St. Petersburg, Chelyabinsk and Novosibirsk. Invitro laboratory uses advanced equipment and test systems from leading manufacturers. It offers a range of research, including the MAP test invitro.

Semen and mar- (MAR-) test: the rate and decoding

In some cases, prescribe spermogrammu and MAP test? These studies are necessary in order to identify any problems of the male reproductive system. Semen is a single final document, in which the doctor brings together all the results. MAP test and semen analysis even help identify those diseases that occur hidden (latent).

This analysis is the most informative to identify different pathologies.

The order and type of additional studies

Mixed agglutination reaction is literally mixed agglutination reaction, more commonly known in a wide range as a MAR-test. Major difference from all other studies is that a positive result is considered to be very poor.

MAP test - this is the main method for determining factor infertility in terms of the immune system. If a semen analysis evaluates qualitative and quantitative composition of the seminal fluid, or points out the problems of infectious viral or order of men, the MAP test is associated with ACAT.

Semen and MAR-test - the study of male seminal fluid, where a doctor sets the number of sperm in their normal percentage of all those present male sexual gametes. But here the "normal" sperm are those that are covered by the ACT and should not participate in the fertilization of the egg (as opposed to semen).

The study was conducted in the following cases:

• effect of infectious and viral factors on male fertility;
• male infertility;
• preparation for ICSI, IVF or IUI;
• agglutination of male sexual gametes;
• Planning the baby is born, and so. n.

What is the essence of research

Semen (and the MAR-test) to diagnose a man's fertility decline any option semen. Properly conducted decoding by an andrologist semen allows you to set a realistic picture the occurrence of infertility in men, diagnose and predict the likelihood of natural conception.

Analysis primarily needed to detect male sterility and determine its type.

Criteria for method and the basic indicators of semen MAR-test:

• mobility "tadpoles";
• morfosostav sperm analysis;
• division into classes based on their sperm motility;
• viability "tadpoles";
• MAP test, determination of immune properties ejaculate, to prevent the possibility of immune infertility;
• acidity and volume;
• leukocytes and flora;
• during liquefaction, viscosity, sperm type.

In general, the criteria for semen evaluation is divided into two categories: The characteristics of "spermatozoa" and ejaculate. Currently, increasingly began to pay attention to immune infertility in men, which is carried out and the MAP test.

Indications for use of the method

IDA-administered test, when the reason for the lack of a child has not been established after all kinds of research. ACAT class G at spermogramme regarded as normal, but in fact they are not able to carry out insemination. MAR-test helps to ascertain the number of "defective tadpoles."

Indications for:

• agglutination, aggregation;
• prolonged infertility couples with all the other positive results;
• low motility and viability of sperm;
• preparation for IVF.

In most cases the analysis is prescribed if a couple can not conceive a child, and the deviations from the woman was seen.

The reasons that appear ACAT and the body begins to attack its own cells:

• disturbance of the natural barrier between blood vessels and the seminiferous tubules;
• MPS pathology;
• infectious agents, STDs;
• other causes of unknown etiology.

Recently approved by the data on which promiscuity, even with the use of a condom, become a cause of generating ACAT any foreign protein is perceived by the body as a potential male threat.

Terms of preparation for the passage of semen and MAR-test almost identical. Ejaculate obtained by masturbation in the laboratory conditions (most), the results are usually ready in the next day.

Decoding results

MAR-test 100% indicates a low probability of becoming pregnant naturally. Usually, doctors advise a couple undergo IVF-ICSI procedure.

Article on the subject: Explanation of semen: What You Need to Know

Reliably and correctly assess the results of analysis can only be a specialist. If the results of MAR-test positive, there are 50% of active sperm covered ACAT, the nature of the immunological infertility in men confirmed. Normal - up to 10% to 50% - the analysis is considered negative.

Thus, semen and MAR-test can detect the number of normal 'spermatozoa', diagnose male infertility and allows the doctor to make an accurate and assign treatment.

MAR-test (IgG, IgA). Direct and indirect test for immune infertility

MAR-test - this immunological study, antibodies to their own sperm. It gives grounds to make a diagnosis "immunological infertility" in men.

In this case, the sperm do not lose their locomotor activity, but are not able to conceive. immunoglobulins types IgG, IgA and / or IgM directed against antigens of the sperm membrane different parts - head, tail, middle portion, or combinations thereof. MAR-test - this study, antibodies to their own sperm.

Education is a universal antibody defense mechanism against foreign agents - viruses, bacteria, tumor cells. They are formed by substances which "recognizes" the cells of the immune system as foreign. Typically, this cell wall protein molecules (antigens).

If for some reason the sperm shell becomes too "foreign" to the body, they produce antibodies of several classes:

• Immunoglobulin Class A - produced by special cells of the mucous membranes and are responsible for local immunity.
• Immunoglobulin M - first synthesized in the immune response, but retained only 14 days. Therefore, in the MAR-test does not define them.
• Immunoglobulin G - produced later, but persist for life, playing a major role in neutralizing antigens.

Antibodies to sperm (ACAT antisperm antibodies) of various classes and circulate in the blood are in a large amount in semen or cervical mucus in women. They surround germ cells and prevent fertilization. In this case, sperm motility is preserved, which gives the standard normal levels of semen.

MAR-test (mixed antiglobulin reaction, in the embodiment, Russian - MAP test) - determining the amount of the ACAT in biological fluids (blood, semen, cervical mucus). This is the only way to diagnose immunological causes of infertility in men.

IMPORTANT!According to WHO recommendations displayed simultaneously semen analysis and MAR-test. Collection of study material (semen) is performed by the same method. You can use a single template for both diagnostic procedures.

Straight

Determining the percentage associated with sperm antibodies in semen and cervical mucus in women. Additionally conduct post-coital test (study of cervical mucus right after sexual intercourse).

Indirect

Subjects - blood. It is indicated in a significant reduction in the speed of sperm, which makes it impossible to hold direct MAR-test.

• Infertility in men, especially after an illness, a negative impact on fertility.
• Pathology in spermogramme: gluing cells or their low mobility.
• Preparation for IVF, ICSI.
• Surgery and trauma male reproductive organs.
• Planning to become pregnant couple.

The list contains more points, but they all belong to the competence of the andrologist.

MAR-test is carried out to men when it is necessary to confirm or refute the diagnosis.

Regardless of the type of antibody assay is based on the general principle - the ability of sperm coated ACAT glued with antisera (blood plasma containing antibodies G or A).

• The biological material is mixed on a slide with the latex beads or erythrocytes coated with immunoglobulin (G or A).
• Was added to a mixture of the appropriate antiserum.
• Examine the mixture under a microscope.

Calculate the percentage of cemented conglomerate to the total number of spermatozoa. Optionally, you detect which parts are attached to the antibody (to a head, neck, tail). By modern standards, in specialized laboratories simultaneously carried out immediately three studies: semen analysis, direct and indirect MAR-test.

The result of analysis can be of two types:

• Positive - number of cells coated ACAT is 50% or more. This means that conception difficult.
• Negative - "bound" sperm count of less than 50%. That's good, because the fertilization of this material is possible.

We absolutely healthy men average MAR-test is 10%.

Training

It depends on the type of MAR-test:

• Indirect - denied any alcohol for 7 days prior to sampling of the material.
• In direct men - 2-3 days abstain from sexual intercourse for 7 days exclude alcohol, smoking, thermal exposure (Bath, physiotherapy), drugs, limit fatty, spicy, salted food.

There are times when with the correct preparation of the study does not give the result: an insufficient number of motile sperm, absence of germ cells in semen or critically small quantity, the presence of only the dead spermatozoa in the portions ejaculate.

Interpretation of test results should be conducted by experienced andrologists who every day face the problems of male infertility. In addition, the results are affected by the quality of reagents and laboratory experience. Donating sperm to study better in a specialized laboratory. Laboratory spermatologii Clinical Diagnostic Center of the Department of Clinical Andrology RUDN narrowly focuses only on the analysis of the ejaculate. We are trusted by professionals in the field of reproduction.
