Genetic Testing and Sex Selection
Preimplantation genetic testing (PGT) is a procedure used in conjunction with in vitro fertilization (IVF) to select embryos free of chromosomal abnormalities and specific genetic disorders for transfer to the uterus. PGT improves the likelihood of a successful pregnancy and birth for two distinctly different groups of patients; couples with infertility related to recurrent miscarriage or unsuccessful IVF cycles and couples who are at risk for passing on an inherited genetic disease to their offspring.
Preimplantation genetic testing may be recommended by your physician when there is a possibility, indicated by your medical history or advanced maternal age that your embryos could be affected by a genetic disease. PGT can only be performed within the context of an IVF cycle where eggs and sperm, united in the laboratory, develop into embryos.
Today, PGT technology reduces the potential for adverse pregnancy outcomes for couples ‘at risk’ by testing the embryos for certain genetic abnormalities before they are chosen for transfer back to the woman. For example: 10 embryos resulted from an IVF cycle and through PGT testing, six were identified as genetically abnormal and four were normal. Using this knowledge, only the normal embryos will be selected for embryo transfer, reducing the possibility of miscarriage or birth defects.
