Patients who are inherited disease carriers ( chromosomal aberrations in number and morphology, as well as gene mutations).

This method has been used in our center since 1999. It consists of the biopsy of a single blastomere per embryo and its genetic diagnosis, using different techniques (PCR, FISH). This is subsequently followed  by the  replacement to the patient of those embryos classified by genetic diagnosis as normal, in order to avoid inherited diseases.
