Preimplantation Genetic Diagnosis (PGD) is a technique that complements IVF/ICSI and helps us detect the presence of genetic abnormalities in embryos before their transfer to the maternal uterus.
Currently, it is done by performing an biopsy to the trophoblast of a blastocyst embryo, that is, on days 5-6 of embryo culture. The cells removed can be examined to detect the presence of chromosomal abnormalities using PGS (Preimplantation Genetic Diagnosis), or genetic diseases, such as Duchenne muscular dystrophy (DMD).
