PGS for 23 Chromosome pairs

The first healthy baby after pre-implantation genetic diagnosis in AVA-Peter was born in 2000.

Since 1999 AVA-Peter was the only clinic in Russia which could help men and women carriers of chromosome aberrations (translocations, inversions and deletions) to use own egg and sperm and become mothers and fathers of healthy children having no chromosome aberrations. Couples from all over Russia came to AVA-Peter to exclude genetic disease in an off-springs.

In 2013 AVA-Peter has implemented PGS for 23 chromosome pairs  which helps to increase IVF success rates

A wrong chromosome number in an embryo is the major reason for a morphologically good embryo not being able to attach and/or progress to a live born baby. Testing of all 23 chromosome pairs in "good looking " blastocysts helps to choose those for transfer which do not only have the highest chance to attach, but also to stay and result in live birth.

PGS for 23 chromosome pairs eliminates the negative effect of maternal age on implantation and reduces time to pregnancy.
