Summary
In Australia 1 in 6 couples require IVF to conceive. Although pregnancy rates have improved over the last 10 years the live birth rate in Australia per cycle is only 17%. This project will assess a new method for the culture of embryos for the ability to maintain embryo vitality and produce healthy babies.
Reappraisal Of The Mechanisms Underlying Implantation Success Or Failure

Summary
Infertility affects 1:6 Australian couples; these seek help. However, for each IVF cycle, there is only ~18.5% chance of a live birth, significantly due to failure of embryo implantation. We discovered nano-vesicles in the uterine cavity, that are released from the womb lining and taken up by the pre-implantation embryo to improve its implantation potential. We will determine how this extracellular environment can enhance implantation success and circumvent/management of infertility.
Genetic testing of IVF embryos promises to improve success but shows no effect of live-birth rates. Many embryos are mosaic: containing cells with correct and incorrect chromosome numbers. Current testing is an invasive biopsy which fails to diagnose how many cells are abnormal in the cells that develop into the baby. Here we will use imaging to determine the ratio of abnormal:normal cells resulting in a non-invasive diagnostic that will improve IVF success.
I am a reproductive biologist, studying how the environment, both in vivo and in vitro, interacts with oocytes and early embryos in determining both their short and long-term development, with specific interests in application to clinical infertility treatment.
Developing An In Vitro Model Of A Human Blastocyst

Summary
Using novel cellular and molecular technologies we propose to develop an artificial model of an early human blastocyst. This will allow us to study the first initial steps in human development without the use of real embryos. Such a model will not only help us decipher the first steps in human development, but we anticipate it will be essential to study how gene mutations and the environment affect this initial step in human development.
