I-20: Towards The Transparent Embryo: Dynamics and Ethics of Comprehensive Preimplantation Genetic Screening
Background: To study the ethical aspects of comprehensive preimplantation genetic screening (PGS) through microarrays and whole genome sequencing Materials and Methods: In order to pinpoint ethical issues regarding comprehensive embryo screening we have first investigated the technical and moral issues by organizing a campus meeting with experts and by a literature study. Subsequently we have i...
متن کاملIn vitro fertilization with preimplantation genetic screening.
BACKGROUND Pregnancy rates in women of advanced maternal age undergoing in vitro fertilization (IVF) are disappointingly low. It has been suggested that the use of preimplantation genetic screening of cleavage-stage embryos for aneuploidies may improve the effectiveness of IVF in these women. METHODS We conducted a multicenter, randomized, double-blind, controlled trial comparing three cycles...
متن کاملTips and Tricks in Fluorescence In-situ Hybridization (FISH)- based Preimplantation Genetic Diagnosis /Screening (PGD/PGS)
As numerical and structural defects in chromosomes are an inevitable consequence of IVF, Pre-implantation genetic diagnosis and screening (PGD/PGS) methods are used for detecting abnormalities in embryos before implantation to the uterus to increase the successful rate of IVF. Pre-implantation genetic diagnosis and screening approaches can be achieved by different techniques such as NGS, CGH an...
متن کاملPreimplantation Genetic Testing
Preimplantation genetic testing (PGT) involves analysis of biopsied cells as part of an assisted reproductive procedure. It is generally considered to be divided into 2 categories. Preimplantation genetic diagnosis (PGD) is used to detect a specific inherited disorder and aims to prevent the birth of affected children in couples at high risk of transmitting a disorder. Preimplantation genetic s...
متن کاملPreimplantation Genetic Screening
In the last 30 years, genetic testing techniques have been developed to identify chromosomally normal embryos in vitro, thereby potentially increasing the proportion of successful cycles with elective single-embryo transfer, and minimizing twin-pregnancy complications and miscarriages. This testing is termed "pre-implantation genetic screening" (PGS), in contrast to preimplantation genetic diag...
