Preimplantation embryo screening at Invimed

As a modern clinic, Invimed offers the possibility to test embryos for genetic defects before performing the transfer. In Invimed clinics we perform several types of preimplantation genetic testing of embryos.

When to genetically test embryos?

The correct diagnosis of genetic defects involves a series of laboratory tests to confirm or exclude congenital genetic defects in both partners. However, it should be remembered that in some cases, genetic defects only become apparent in the offspring, which is why PGT-A and PGT-M preimplantation diagnosis is recommended. Preimplantation genetic testing of embryos allows the detection of defects in the structure and number of chromosomes (PGT-A, Embrace) of the embryo, which can be the cause of non-implantation, early miscarriage after implantation or cause severe malformations in the child.

  • NEW! Embrace

Invimed was the first infertility clinic in Poland to introduce the non-invasive, preimplantation genetic embryo test Embrace, which makes it possible to check for numerical chromosome abnormalities (aneuploidy). This test promotes safer and more effective IVF treatments and avoids embryo biopsies. This method classifies embryos according to their chance of implantation. Normal embryos of the best quality receive the highest priority for transfer.

  • PGT-A

Preimplantation genetic testing for aneuploidy (preimplantation genetic testing for aneuplodies, formerly called PGS) at Invimed is performed using Next Generation Sequencing (NGS). It allows a detailed reading of the entire genome of the embryo for the study of structural and numerical abnormalities. The PGT-A test detects structural and quantitative changes in chromosomes. Any such abnormalities can cause genetic diseases such as Down syndrome (trisomy 21 of a pair of chromosomes) or Patau syndrome (trisomy 13 of a pair of chromosomes).

  • PGT-M

PGT-M is a preimplantation genetic diagnosis that allows the genetic material of an embryo to be analysed for mutations of a single gene (monogenic mutations), responsible for the development of specific genetic diseases. It is an extremely sensitive method. It can detect diseases such as cystic fibrosis, haemophilia or spinal muscular atrophy. Mutations in genes in offspring can be passed on by defective genetic material from one or both partners, as well as by so-called de novo mutations, i.e. those that arise when healthy genetic material is passed on - so-called new mutations.

The doctor, after a thorough examination of the patient's condition, determines the extent and frequency of diagnostic tests and/or therapeutic procedures, taking into account specific medical indications. All medical decisions are made in full consultation with the patient.
