Abstract
Preimplantation genetic testing (PGT) involves taking a biopsy of an early embryo created through in vitro fertilisation (IVF) or intracytoplasmic sperm injection (ICSI). Genetic testing is performed on the biopsy, in order to select which embryo to transfer. PGT began as an experimental procedure in the 1990s, but is now an integral part of assisted human reproduction (AHR). PGT allows for embryo selection which can reduce the risk of transmission of inherited disease and may reduce the chance of implantation failure and pregnancy loss. This is a rapidly evolving area, which raises important ethical issues. This review article aims to give a brief history of PGT, an overview of the current evidence in PGT along with highlighting exciting areas of research to advance this technology.
期刊介绍：
In practical paperback format, each 200 page topic-based issue of Best Practice & Research Clinical Obstetrics & Gynaecology will provide a comprehensive review of current clinical practice and thinking within the specialties of obstetrics and gynaecology.
All chapters take the form of practical, evidence-based reviews that seek to address key clinical issues of diagnosis, treatment and patient management.
Each issue follows a problem-orientated approach that focuses on the key questions to be addressed, clearly defining what is known and not known. Management will be described in practical terms so that it can be applied to the individual patient.
