Preimplantation Genetic Testing (PGT) is recommended in several cases. For example, if you are a carrier of genetic diseases and are afraid of transmitting them to your children, or if you have infertility problems, recurrent miscarriages, or if you are a woman over 40 who cannot conceive naturally. In these cases, PGT can help you achieve a pregnancy with a healthy baby, as it allows for the examination of all 23 pairs of chromosomes to rule out any abnormalities before implantation.
