"¨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...

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 therapies 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...

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...

ESHRE study may answer the question in older women 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 specialised 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...

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...

MGRC unveils comprehensive range of new genetic screening services for inherited and infectious diseases. Kuala Lumpur, Malaysia (PRWEB) July 02, 2011 Malaysian Genomics Resource Centre Berhad (MGRC), one of Asia's leading genome sequencing and analysis service providers, today launched a range of comprehensive genetic screening services, as well as an all-in-one test for a multitude of infectious diseases. Genetic screening examines a person's genome for known variation markers, some of...

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, a researcher told the annual conference of the European Society of Human Genetics today (Monday). Dr. Debby Hellebrekers, from Maastricht University Medical Centre, Maastricht, The Netherlands, said that the scientists' findings could have a considerable effect on preventing the transmission of...

Generates enough material for several tests, improving choice of implanted embryos 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. The results were reported in the April issue of Fertility and Sterility. Because embryos are so small and cells contain too little DNA to...
