Preimplantation genetic testing (PGT)

PGT allows selection of normal embryos to be transferred to the patients who are at risk of severe genetic diseases and is an alternative to prenatal diagnosis.

It is indicated when the fetus is at risk of monogenic diseases, chromosomal abnormality (e.g. balanced translocation in the couple) or in women with advanced maternal age or recurrent pregnancy loss.

Gender selection for non-medical reasons is not allowed in Hong Kong.
