Abstract

Introduction and Purpose: This paper examines current trends in assisted reproductive technology, specifically the use of preimplantation genetic diagnosis (PGD to help in the preimplantation detection of genetic abnormalities such as monogenetic diseases and aneuploidy. PGD can be carried out in different stages, and the timing of the procedure has become one of the major issues in implementation. Three major stages of biopsy have been applied when carrying out PGD: Polar body biopsy (pre-conception), cleavage stage biopsy (3 days after conception), and blastocyst stage biopsy (6 days after conception). The purpose of the paper was to explore these stages and come to a conclusion on the best one in regard to the safety of embryos and the effectiveness of diagnosing genetic abnormalities.
