Recurrent miscarriages are considered when at least two pregnancies have ended in miscarriage, whereas we speak of implantation failure when a patient has not achieved pregnancy after several good-quality embryo transfers.
We believe recurrent miscarriages and implantation failures result in the same conclusion. In the event of implantation failure, abnormalities are produced before the embryo has started to develop inside the uterus.
You can find below the most common causes of recurrent miscarriages.
This is the most common cause for recurrent miscarriages and implantation failures. Genetic abnormalities of the embryos may lead to them not implanting or the pregnancy ending in miscarriage.
Most of the embryos that have genetic abnormalities can develop normally in the laboratory, which means preimplantation genetic diagnosis is the only way to identify them.
The most important uterine causes for recurrent miscarriages and implantation failures are:
Examination of recurrent miscarriages and implantation failures must include the following diagnostic tests.
Allows us to study the uterine cavity to eliminate malformations, polyps, myomas or adhesions.
Tests on the ovarian reserve may alert us to an egg problem.
Thyroid function tests includes examining the TSH and T4L hormones.
Miscarriage treatment is determined by their cause. The cause of recurrent miscarriages occasionally cannot be diagnosed and, in that case, the indicated treatment is In Vitro fertilisation with Preimplantation genetic diagnosis. This technique allows us to examine the embryo chromosomes and ensure that we will transfer normal embryos.
