In the PERSONA International Clinical Center for Reproduction, a complete genetic examination is available for couples with infertility, miscarriage, and unsuccessful IVF attempts.

Preimplantation genetic research of embryos (PGD / PGS) with full chromosomal screening by comparative genomic hybridization (aCGH)

RESEARCH ACCURACY - UP TO 98%

RESEARCH OF ALL 46 CHROMOS

PROBABILITY OF PREGNANCY WITH PDG aCGH - 60-70%

Preimplantation genetic diagnostics by the method of genomic hybridization on microchips (aCGH) is one of the most innovative technologies in modern reproductology.

The technology has been used in the world since 2009.

Diagnostics of CGH allows to detect chromosomal pathology with high accuracy (up to 98%) on all 23 pairs of chromosomes before embryo transfer in ART cycles (assisted reproductive technologies). The method increases the success of the IVF procedure up to 60-70%, instead of the usual 30-40%. A more “old” method of genetic diagnosis of embryos - FISH allows you to check only 3 to 9 pairs of chromosomes, i.e. most of the chromosomes remained untested.

The first child, tested by the CGH method, was born in 2009.

Why it is important to conduct a preimplantation genetic study of embryos (PGD / PGS) with full chromosomal screening using the comparative genomic hybridization (aCGH) method:

• Increased probability of pregnancy with ART. Reducing the cost of subsequent IVF and related risks (ovarian hyperstimulation syndrome, risks during egg collection and general anesthesia, psychological stress). The presence of a genetically suitable embryo avoids unnecessary transfer;
• High chances of pregnancy when transferring only one embryo (without reducing the effectiveness). No risks associated with multiple pregnancies.
• Elimination of the risk of carrying and having a child with Down syndrome, Shereshevsky-Turner, Kleinfelter, Edwards, Patau, and other chromosomal pathologies.
• The most common cause of abortions and undeveloped pregnancies is chromosomal abnormalities in the fetus. Preimplantation genetic diagnosis of aCGH reduces the risk of abortion for up to 12 weeks, as well as psychological stress.

The method of comparative genomic hybridization should be carried out in the case of:

• If the history of the disease already has one or several "missed" pregnancies
• two or more failed IVF attempts
• Age of mother over 37 years old
• severe male infertility
• If the patient has already been diagnosed with a pregnancy with a chromosomal abnormality, or the couple already have one child with a chromosomal abnormality;
• One or both parents are carriers of balanced structural chromosomal abnormalities
