Artificial insemination: how it happens?

 artificial insemination
 Artificial insemination - is a technique that helps with certain types of infertility in both women and men. During this procedure, the sperm is injected directly into the cervix, fallopian tubes or the uterus. Thus, it is easier to get sperm to the egg, since on their way there are no obstacles. Ideally, this should contribute to pregnancy to those who did not manage to do this before.

Intrauterine insemination, in which sperm is placed directly into the uterus - the most common form of artificial insemination.

Although the chance of getting pregnant by artificial insemination may not be as great as when using a new and sophisticated methods, this technique has a key advantage: it is simple and has very few side effects. For this reason, doctors often recommend in vitro fertilization as the first way to treat infertility Infertility Treatment - What principles are priority  Infertility Treatment - What principles are priority

 Artificial insemination: how it happens?

In what types of infertility helps artificial insemination?

Artificial insemination can be used for various problems with fertility. For example, it may help if the sperm are not strong enough to go alone into the cervix and fallopian tubes. Artificial insemination can be effective for women who have been diagnosed with endometriosis, or if there are any abnormalities of the reproductive organs.

This procedure often takes a woman with such violations as secret immunity cervical canal. This disorder is characterized by the fact that the mucous membrane of the cervix is ​​an aggressive medium for sperm cells and prevents them from entering the uterus. Through artificial insemination sperm can pass all the hazards to the site.

In addition, the doctor may suggest artificial insemination, if you can not establish the reason why the couple can not have children.

 Artificial insemination: how it happens?

The procedure

First, the patient is undergoing tests using ultrasound and gives blood for analysis. This is to ensure that the physician will be able to carry out the procedure of artificial insemination during ovulation Ovulation - How to determine as accurately as possible?

 . Your partner will need to pass the sperm for the procedure. If you live near the clinic, it can be done at home, but if not, it will provide a separate room. It is recommended to abstain from sex for 2-5 days prior to undergoing the procedure, as this will increase the concentration of viable sperm.

Within an hour after ejaculation in the laboratory carried out "cleansing" of semen. This increases the probability of pregnancy because sperm are removed from a substance which may cause irritation or discomfort to the woman's body. Then, using a special harmless chemical separates the most active sperm.

In the procedural sperm is placed in the catheter through which it is introduced into the uterus. Artificial insemination - a quick and relatively painless procedure. In some women, it causes the lungs spasm and minor bleeding.

After the procedure, you need to lie down for at least 15-45 minutes to allow the sperm to fulfill their work. Factors that may reduce the probability of successful in vitro fertilization:

  • The elderly woman
  • Poor egg quality
  • Poor quality of sperm
  • Strong endometriosis Endometriosis - a serious problem with serious consequences  Endometriosis - a serious problem with serious consequences
  • Severe damage to the fallopian tubes (usually caused by chronic infection)

Artificial insemination does not help everyone. Some couples have to go through the procedure several times before you get pregnant; some are not possible at all. Sometimes, to increase the chances of getting pregnant, the patient prior to the procedure are hormone therapy Hormone therapy - is it possible to fool nature?

  • Treatment of risk

 fetal tachycardia
 Tachycardia fetus - is an abnormal increase in heart rate of the fetus and is defined as a heart rate above 160-180 beats per minute. As a rule, tachycardia fetal heart rate is 170-220 beats per minute (with tachyarrhythmia observed more frequent cuts).

The first case of fetal tachycardia S. Hyman recorded in 1930. Today, the estimated prevalence is at 0, 4-1 pregnancies. In most cases, the hearth of abnormal electrical pulses are atrium. Tachycardia fetus can range from a simple sinus tachycardia Sinus tachycardia: a violation of the heart  Sinus tachycardia: a violation of the heart
   to a variety of tachyarrhythmias. Fetal tachycardia can be caused by many diseases, both mother and child: the mother - Hyperthyroidism Hyperthyroidism: increased secretion of thyroid hormone  Hyperthyroidism: increased secretion of thyroid hormone
   and taking certain medications; the fetus - fetal infection, fetal hypoxia, anemia, fetal chromosomal abnormalities (Patau's syndrome or trisomy 13 (chromosomal human disease that is characterized by the presence of an extra chromosome in the cells 13) and Turner syndrome).

 Fetal Tachycardia: identifying at early stages

Recommended study:

  • radiographic
  • ultrasonography
  • fetal echocardiography

Doppler M-mode is best suited for the analysis of the fetus. It is desirable that the sampling line is crossed the wall atria and ventricles that allow for the simultaneous assessment of the reduction of both ventricles and atria. When fetal ultrasound Doppler technique is used to detect motion, mainly red blood cells (RBCs). So it is revealed blood flow in the heart and other vascular lesions.

Ultrasound can also show the defects and complications of the fetus, for example, signs of fetal hydrops.

Treatment and prognosis

In most cases, long-term prognosis when diagnosed sinus tachycardia fetus is generally favorable, abnormal heart rate stabilized during the first year of life. For the treatment (if necessary) is carried out transplacental administration of antiarrhythmic drugs.

Differential diagnosis

  • Supraventricular reciprocating tachycardia Tachycardia - the body to the limit?  Tachycardia - the body to the limit?

The most common type of fetal tachycardia is a supraventricular reciprocating tachycardia. Scientists have shown that the transient atrioventricular connection is normal in the early stages of fetal development, but noted that the preservation of these bonds in late pregnancy may contribute to the development of reciprocating tachycardia. The presence of fetal arrhythmia Beats - heart rhythm disturbances  Beats - heart rhythm disturbances
   atrial (as observed in 1-2% of pregnancies) can lead to supraventricular (supraventricular) tachycardias, which usually occurs at 24-32 weeks of gestation .  If supraventricular tachycardia proceeds to sinus rhythm, heart rate should return to normal for gestational age (in the absence of drug therapy) .  When combined with fetal tachycardia, bradycardia, it may be suspected long QT interval syndrome or the presence of inflammatory conditions .  In this case, the choice of antiarrhythmic drugs may be hampered because of the need to avoid drugs that prolong the QT interval .  In general, the best indicator of tachycardia - it occasionally or permanently changing the atrioventricular or ventricular-atrial conduction, identified by echocardiography .  If during an episode of tachycardia, there are obstacles atrioventricular or ventricular-atrial conduction, supraventricular tachycardia reciprocal rule and consider other forms of tachycardia .

  • Auricular flutter

Atrial flutter is observed in approximately 30% of cases of fetal tachyarrhythmia. Most fetuses diagnosed with prenatal atrial flutter, there is an additional atrioventricular connection, which can lead to the development of atrioventricular reciprocating supraventricular tachycardia in utero or postnatally. Atrial rhythm in atrial flutter, usually less than 400 beats per minute, and usually is regular and combined variable atrioventricular block. Atrial rhythm with other forms of atrial tachycardia or is irregular (chaotic atrial tachycardia) or kept at 180-240 beats per minute (ectopic atrial tachycardia).

Other forms of fetal tachycardia

Atrial ectopic tachycardia - a form of primary atrial tachycardia. Ectopic foci can be localized in any parts of the atria, but more often detected in the eye or the side wall of the right atrium, in the area of ​​confluence of the pulmonary veins. Atrial ectopic tachycardia is caused by the presence of auto focus or trigger activities outside the site. In this state, the atrioventricular node passively activated. Atrioventricular node as passive when the chaotic atrial tachycardia, uzloy ectopic tachycardia and ventricular tachycardia. The nodal and ventricular tachycardia is rare, but increasingly found in utero.
