Latest Preimplantation genetic diagnosis Stories
At present, when a woman undergoes preimplantation genetic screening (PGS) in a fertility clinic, doctors are trying to select an egg or an embryo that is healthy and doesn't have a chromosome abnormality such as an extra copy of chromosome 21, which causes Down's syndrome.
Professor William G. Kearns told the annual meeting of the European Society of Human Reproduction and Embryology that a three-day-old embryo (called a cleavage stage embryo) with an incorrect number of chromosomes (known as "aneuploidy") was capable of undergoing "a dynamic process of genetic normalisation" so that by day five, when it had developed to the blastocyst stage, it had become euploid, with the correct number of chromosomes.
Ovarian stimulation undertaken by women of advanced maternal age (over 35 years) receiving fertility treatment may be disrupting the normal pattern of meiosis â€“ a critical process of chromosome duplication followed by two specialized cell divisions in the production of oocytes and sperm â€“ and leading to abnormalities of chromosome copy numbers (aneuploidy) that result in IVF failure, pregnancy loss or, more rarely, the birth of affected children with conditions such as...

Pre-implantation genetic diagnosis (PGD) can give women at risk of passing on a mitochondrial DNA disorder to their offspring a good chance of being able to give birth to an unaffected child.
Researchers at the Johns Hopkins University School of Medicine have devised a new technique, which helps couples that are affected by or are carriers of genetic diseases have in vitro fertilized babies free of both the disease in question and other chromosomal abnormalities.

Human Reproduction is a peer-reviewed scientific journal that concentrates on original research, clinical case studies and opinions and debates on topical issues. The journal was broken into three distinct journals in 1995, with Human Reproduction Update and Molecular Human Reproduction. Human Reproduction Update is a bimonthly review journal and Molecular Human Reproduction is a monthly journal focusing on molecular aspects of reproductive biology. Human Reproduction covers all aspects...
