-- Program of Einstein Medical Center Philadelphia Uses Simple Blood Test to Identify Carriers of 19 Preventable Disorders Common to Ashkenazi Jews -- PHILADELPHIA, July 11, 2011 /PRNewswire-USNewswire/ -- In the past, prospective parents had no way of knowing whether they were carriers of a genetic disease that could threaten the health and life of their children - until it was too late and a child became sick. For Jewish individuals of Central and Eastern European descent, the potential...

"¨In a conscience vote held Thursday, the German parliament approved the use of preimplantation genetic diagnosis (PGD), a procedure in which one or two cells are extracted from a developing embryo in order to test for genetic disorders, according to Reuters reports."¨In their July 7 article, Thorsten Severin and Eric Kelsey report that the newly approved legislation "will allow screening embryos of parents who have a predisposition to severe genetic disorders, where a pregnancy would...

Other important data the European IVF Monitoring group (EIM) on 2008 cycles and the International Committee Monitoring Assisted Reproductive Technologies (ICMART) on 2007 cycles highlighted were Sweden's low rate of multiple births "“ the lowest in the world "“ and Spain's 30 % share of egg donations in Europe.The EIM collected data on frozen oocyte retrieval (FOR) cycles for the first time. Until today, egg freezing is still not offered on a wide scale but can be an option for women who...

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. In order to establish this, they either have to biopsy a part of the egg called the polar body or remove a cell from the embryo for screening. Both procedures are expensive, invasive and can damage the egg or embryo.Dr...

Findings have significant implications for fertility treatment and stem cell therapiesProfessor 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...

Ovarian stimulation undertaken by women of advanced maternal age (over 35 years) receiving fertility treatment may be disrupting the normal pattern of meiosis "“ a critical process of chromosome duplication followed by two specialized cell divisions in the production of oocytes and sperm "“ 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 Down's syndrome,...

Physicians are well aware that the chance of birthing a child with Down's syndrome increases with the age of the mother, especially for those over 35. Researchers are now also finding links between Down's syndrome and drugs used in in-vitro fertilization (IVF) for older women, BBC News reports.UK researchers looking at 34 couples have discovered a link with IVF in older women disturbing the genetic material of her eggs. The magnitude of the risk is still unknown but it could also cause many...
