Summary
Due to the obvious limitations to studying human pregnancy, the mouse has become a valuable model. However, invasion of the placenta into the uterine wall and vasculature, critical for successful pregnancy, is poorly understood in the mouse. The aims of the proposal are designed to gain a better understanding of these processes in mice and will provide a more accurate model system to study serious pregnancy complications resulting from abnormal placental invasion, such as preeclampsia.

Summary
Assisted reproductive technology (ART) deals with issues of fundamental importance to individuals involved, and society as a whole. Despite major advances, ART continues to be very costly in many regards. A major reason for this is the relatively low rate of pregnancy, which averages 25% per procedure. The common response to the problem of low pregnancy rates is to return several embryos to uterus. A dilemma associated with this strategy is the high risk of multiple pregnancy, which is associate ....Assisted reproductive technology (ART) deals with issues of fundamental importance to individuals involved, and society as a whole. Despite major advances, ART continues to be very costly in many regards. A major reason for this is the relatively low rate of pregnancy, which averages 25% per procedure. The common response to the problem of low pregnancy rates is to return several embryos to uterus. A dilemma associated with this strategy is the high risk of multiple pregnancy, which is associated with adverse consequences for mother and fetus(es). Compared to singleton births; fetal, neonatal, and perinatal mortality rates are 3-6 times higher in twins, and 5-15 times higher in multiple births of a higher order. Cerebral palsy rates among survivors are six times higher in twins and twenty times higher in triplets. The increase in the incidence of adverse outcomes related to multiple pregnancy has been well documented in ART. We propose a randomised controlled study to assess single embryo transfer (SET) compared to double embryo transfer (DET). Infertility women with a high risk of multiple pregnancy will be randomly allocated to receive one or two embryos, which is the usual treatment at present. We shall then examine the rates of single and multiple pregnancies, and the success of those pregnancies in this group of patients. Potential benefits to the community from this project are very substantial, as it has the capacity to substantially reduce the number of multiple births. Patients will also benefit by having more accurate information with which to make an informed choice during treatment.Read moreRead less
Determining The Impacts Of Epigenetic Modifying Drugs On Germline Programming And Offspring Health

Summary
New drugs have been developed that inhibit specific enzymes that regulate epigenetic pathways in cells. These pathways significantly affect growth and development in offspring and may represent a risk to future children of patients taking the drug. This project will determine these risks and provide data for developing clinical guidelines for safe use of the drugs.
