PGD - Overview
PGD is a method to determine whether there are any genetic anomalies on the embryos created via IVF treatment.
Normal IVF treatment is performed on the female wishing to do PGD. Eggs are collected and fertilized with sperm using microinjection (ICSI). After fertilization, genetic screening is performed on the embryos in order to only transfer the healthy embryos. This enables genetic testing of embryos and results in pregnancy without any genetic anomaly on the tested chromosomes.
Screening for several genetic disorders are performed before transfer of healthy embryos to the female. Thanks to PGD (Preimplantation Genetic Diagnosis) genetic disorders like Down’s syndrome, Monosomy and Trisomy can be screened. Chromosomes (13, 15, 16, 17, 18, 21, 22, X, Y) are checked in PGD-9 testing. Since gender chromosomes are also screened, gender selection can also be performed on cases where some genetic anomalies can pass via the gender chromosome.
