Causes of unsuccessful IVF

The IVF procedure never yields a 100% result. In 40% of cases, the first attempt is unsuccessful. But the reasons for an unsuccessful IVF are, as a rule, surmountable.

What can lead to a negative result?

  1. Poor quality of the embryo. It can be caused by poor egg cells or sperm cells. Here much depends on the qualification of the embryologist. If the cause is in the embryo, it is better to change the doctor or clinic.
  2. Pathology of the endometrium. The endometrial layer should be from 7 to 14 mm.
  3. Pathology of fallopian tubes . If hydrosalpinks were found during the examination (accumulation in the fluid cavity of the tubes), then before the protocol it is necessary to remove the formation with laparoscopy.
  4. Genetic problems. Some embryos die due to abnormalities in the chromosomal structure. If a couple already has several unsuccessful IVF attempts, then the partners are checked for karyotype. In the norm - 46хх and 46х. If there are deviations, then before embedding the embryo make genetic diagnosis.
  5. Immune pathologies. The woman's organism perceives the embryo as an alien organism and actively struggles with it, which leads to an unsuccessful IVF. It is worth doing a study (HLA-typing) on ​​the compatibility of the pair.
  6. Hormonal problems. Special control and supervision is necessary for women with diseases such as diabetes, hypo- or hyperthyroidism, hypo- or hyperandrogenia, hyperprolactinaemia.
  7. Increased coagulability of blood. The hemostasiogram will show all the problems.
  8. We should also note the excess weight. With obesity, the ovaries respond poorly to stimulation.
  9. At the age of over 40 years, the likelihood that an IVF attempt will fail is significantly increased.
  10. Medical errors or failure to comply with appointments by the patient.

Pregnancy after an unsuccessful IVF

After an unsuccessful IVF, the causes should be identified and eliminated. Pregnancy may well occur as a result of the next attempt. To repeat procedure IVF doctors recommend not earlier, than in three months. It is necessary that the cycle is restored after the previous unsuccessful IVF, and the body has returned to normal. Sometimes a doctor can appoint a longer term. Follow the recommendations and take your time! IVF is a serious burden. It is necessary to have a good rest and fully recover. This will increase the likelihood of a successful pregnancy at the next attempt.
