Insemination with obstruction of the fallopian tubes

Intrauterine insemination is one of the methods of artificial insemination that is closest to natural conception. Specially prepared sperm is injected into the woman’s uterus. Sperm move through the fallopian tubes to the egg in order to fertilize it. That is, the further process is the same as with natural conception.

Insemination is contraindicated in cases of obstruction of the fallopian tubes. At the same time, ovulation is preserved. But the sperm cannot reach the egg. With partial obstruction, the risk of ectopic pregnancy increases. Therefore, before carrying out the artificial insemination procedure, it is necessary to conduct a thorough examination.

Symptoms of obstruction of the fallopian tubes

Pathology practically does not manifest itself. That is why preparation for insemination, among other things, involves testing for patency.

The symptoms of clogged pipes in a woman are nonspecific and can be explained by other disorders. It:

  • pain in the lower abdomen outside the cycle;
  • painful menstruation;
  • discomfort during intercourse;
  • discharge;
  • subfebrile temperature.

And, of course, the main symptom of obstruction is the absence of pregnancy for a year with regular sex without contraception.

Artificial insemination is carried out after checking the patency of the tubes. Various methods are used for diagnosis.

  1. Ultrasound. Echo salpingography consists in the introduction of saline into the uterine cavity. The doctor monitors the movement of the fluid using an ultrasound scan, identifying the places where the flow is disturbed.
  2. Metrosalpingography. A radiopaque substance is injected into the uterine cavity. Then a picture is taken, according to which the doctor evaluates the distribution of fluid in the pelvic cavity. The solutions used in the procedure are all iodine-containing, therefore, allergies must first be excluded.
  3. Laparoscopy with chromohydrotubation. Diagnostic surgery allows not only to identify obstruction, but also to immediately eliminate it, if possible. Using a laparoscope, the doctor examines the outer walls of the tubes. Then he injects a sterile solution into the uterine cavity and monitors the patency of the pathways.

If the doctor identifies pathologies, insemination cannot be performed. How to get pregnant with obstruction of the fallopian tubes? There are two ways. A woman with an obstruction may be assigned a different IVF program. Doctors generally recommend IVF. In some cases, the treatment of obstruction of the fallopian tubes will be effective. As a rule, recovery is carried out by laparoscopy. After complete recovery, IUI is possible.

How is artificial insemination done?

With the help of an ultrasound scan, the doctor monitors the maturation of the follicles. When they reach 18-19 mm in diameter, the IUI procedure is performed. At the time of ovulation, specially prepared sperm is injected through a flexible catheter into the uterine cavity: purified and concentrated. Biomaterial from a partner or donor can be used. A man can donate sperm at any time thanks to the cryopreservation service.

It is impossible to see the presence of an egg in the follicle using ultrasound. Its diameter is 150 microns. Therefore, the likelihood of successful fertilization is lower than with other methods. To increase the chances of getting pregnant with IUI, ovulation stimulants may be prescribed, which trigger multiple follicular growth. This increases the risk of multiple pregnancies.

The insemination procedure is painless. After it, the woman spends 15-20 minutes in a horizontal position, and then returns to her usual life. After 2 weeks, the effectiveness of IUI is checked using the analysis of the level of chorionic gonadotropin.

How to prepare for insemination?

First of all, both partners need to give up alcohol and nicotine, avoid stress and intense physical activity. For 3-7 days before the procedure, you should refrain from sexual intercourse.

There are a number of tests for insemination. The man donates blood and undergoes a spermogram. The female examination is more thorough. In addition to checking the patency of the fallopian tubes, the expectant mother needs:

  • undergo an examination by a gynecologist with taking smears from the vagina, cervical canal and urethra;
  • donate blood and urine for analysis;
  • carry out folliculometry;
  • check the level of sex hormones;
  • obtain a therapist’s opinion on the state of health.

All these tests are also prescribed when planning a natural pregnancy. When preparing for the insemination procedure, a woman needs to visit a reproductive specialist several times to track ovulation.
