Embryology is the study of the development of an embryo. An embryo is defined as any organism in an early stage well before birth or hatching, or in plants, before germination occurs.

Smoking, social class may lead to POF in women

POF is not only associated with infertility but also with significantly increased morbidity and mortality, as well as a decreased quality of life equivalent to that of people with type 2 diabetes or rheumatoid arthritis, said Dr. Rumana Islam, from Imperial College, London, UK.

EIM collects data on frozen oocyte retrieval cycles for the first time

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.

Researchers investigate predictors for adverse outcome in IVF singletons

In Sweden almost 40 000 children have now been born after IVF, around 3 500 each year, and IVF children constitute 3% of all newborns. "This represents a large number of children and any adverse outcomes related to IVF are therefore a major public health issue," said Dr. Antonina Sazonova, from Sahlgrenska University Hospital, Gothenburg, Sweden, who carried out the research with colleagues from the hospital and from Lund University.

Study: 'Vanishing twin' linked to increased risk of congenital malformations

Professor Michael Davies will tell the annual meeting of the European Society of Human Reproduction and Embryology today that the "vanishing twin" phenomenon, in which only one child is born from a pregnancy that originally starts as a multiple pregnancy, is linked to a nearly two-fold increased risk in any congenital malformation and to a nearly three-fold risk of multiple malformations.

Periodontal disease can affect woman's chance of conceiving

Professor Roger Hart told the annual meeting of the European Society of Human Reproduction and Embryology that the negative effect of gum disease on conception was of the same order of magnitude as the effect of obesity.

Study: Threatened miscarriages complicate 20% of all pregnancies

Dr Kaltum Adam, an honorary clinical research fellow at St Mary's Hospital in Manchester (UK), told the annual meeting of the European Society for Human Reproduction and Embryology that around 20% of all pregnancies were complicated by threatened miscarriage, and up to 20% of these would miscarry.

Cleavage stage embryo with aneuploidy can undergo genetic normalisation process

Professor William G. Kearns told the annual meeting of the European Society of Human Reproduction and Embryology that a three-day-old embryo with an incorrect number of chromosomes 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.

ICSI study shows strong increase in first trimester pregnancy loss after the age of 38

The research, presented at the annual conference of the European Society of Human Reproduction and Embryology, also showed that rates of preclinical abortion, miscarriage and overall pregnancy loss during the first trimester remained more or less constant until the age of 34, but increased steadily from the age of 35 onwards.

New model may help reduce multiple pregnancies in women

Dr Jan Holte told the annual meeting of the European Society for Human Reproduction and Embryology, that if this model were to be applied in all fertility clinics, it had the potential to reduce the twin rates to the level of just under two percent seen in the normal population. Already, another four clinics have started to use the model.

New insight into oocyte chromosome abnormalities

Ovarian stimulation undertaken by women of advanced maternal age 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 that result in IVF failure, pregnancy loss or, more rarely, the birth of affected children with conditions such as Down's syndrome, which is caused by the inheritance of three copies of chromosome 21.

IVF causing multiple birth rates fall

Birth rates for IVF twins and triplets have begun to fall in line with government targets aimed at reducing health risks caused by multiple pregnancies. This fall shows the efficacy of the guidelines brought in by the Human Fertilization and Embryology Authority (HFEA) that urged UK fertility clinics to limit multiple births to no more than 24% in 2009/10. Among naturally-conceived babies, only around one in 70 is a twin.

Study finds strong link between live birth rates and number of eggs retrieved in one IVF cycle

An analysis of over 400,000 IVF cycles in the UK has shown that doctors should aim to retrieve around 15 eggs from a woman's ovaries in a single cycle in order to have the best chance of achieving a live birth after assisted reproduction technology.

Stanford University creates first stem cell science PhD program in U.S.

Stanford University’s Faculty Senate has approved the creation of what officials believe is the first stem cell science PhD program in the nation and, perhaps, the world. The new doctoral program in stem cell biology and regenerative medicine is also the first interdisciplinary doctoral program created by the School of Medicine in recent years.
