Summary
Implantation of an embryo into the uterus is a key step in establishing pregnancy; it requires a receptive uterus (fertile soil) and a healthy embryo (seed). Implantation failure causes pregnancy loss and infertility, and is also a major limiting factor in IVF. We have established that proprotein convertase 6 (PC6) is a master regulator of uterine receptivity for implantation. We will investigate how PC6 works in a woman’s uterus, and how we can use this knowledge to improve implantation in IVF.
I am a reproductive biologist investigating biological mechanisms that play a role in common women�s health disorders including endometriosis, uterine fibroids, menstrual disorders and reproductive cancers.
Successful establishment of pregnancy requires a viable embryo and a receptive uterus. The contribution that reduced uterine receptivity makes to human infertility is unknown. IVF patients with implantation failure will be investigated using different approaches to identify gene pathways that are altered in reduced uterine receptivity. This study could lead to a clinical test for uterine receptivity and help to improve fertility treatment options for women with repeated implantation failure.

Summary
This proposal seeks to identify the critical maternal and embryonic placental factors that regulate the formation of a healthy placenta and thus a healthy pregnancy and baby. Currently there is no way of identifying whether the placenta is forming adequately. The proposed studies are a necessary first step in identifying therapeutic targets for diseases associated with a poorly formed placenta, such as preeclampsia.
The failure of an embryo to implant is a major cause of infertility. While IVF is an important intervention, still three quarters of embryos do not implant. We have identified new factors that we believe are critically important in embryo attachment to the womb. We will now prove whether these factors are critical and therefore provide the evidence required to begin to develop novel treatment options for infertility.
