Polycystic ovary syndrome (PCOS) affects 5-10% of women worldwide, yet its origins remain unknown. Androgens are implicated in the development of PCOS, but the decisive, invasive studies needed to confirm and elucidate their roles are not feasible in women. Hence, using our innovative mouse models of androgen resistant female mice, this study will determine the role of androgens in PCOS aiming to better understand, and identify new treatments for this common female reproductive disorder.

Summary
Infertility occurs in one in six Australian couples with 50% attributable to females, thus, enhancing our understanding of ovarian and uterine function is of great importance. This project tests the proposal that androgens (steroid hormones) play a major role in regulating female reproductive physiology through their interaction with the androgen receptor. We have developed novel mouse models which we will use to determine the roles of androgens in regulating female reproductive function.
Approximately 1 in 25 men in the western world are infertile, and while environmental and genetic factors are recognized to contribute to disease, there is currently a poor understanding of the basic mechanisms regulating male fertility. Our long term goal is to identify and study key molecules involved in sperm production. Understanding the role of these molecules will provide insight into the causes of male infertility. Ultimately, these studies will assist to develop new treatments for male r ....Approximately 1 in 25 men in the western world are infertile, and while environmental and genetic factors are recognized to contribute to disease, there is currently a poor understanding of the basic mechanisms regulating male fertility. Our long term goal is to identify and study key molecules involved in sperm production. Understanding the role of these molecules will provide insight into the causes of male infertility. Ultimately, these studies will assist to develop new treatments for male reproductive disorders. Conversely, there is a huge need for additional male based contraceptives. Increased understanding of male fertility and identification of proteins exclusively involved in sperm production provides the opportunity to develop new contraceptive treatments.Read moreRead less
Mechanisms Of Escape From Progesterone-induced Suppression: Role In Normal And Preterm Birth

Summary
Prematurity caused by preterm birth is the leading cause of death and disease among newborns in Australia. Here we will define how the length of pregnancy is determined by the opposing actions of progesterone, which maintains pregnancy, and prostaglandins, which induce labour. We will demonstrate the mechanism by which the actions of the two hormones are balanced in normal pregnancy and disrupted in preterm labour. We will show that preterm birth can be prevented by correcting the disorder.
