Summary
Prostate cancer is the most common cancer in Australian males after non-melanocytic skin cancer. Each year more than 10,000 men are diagnosed with prostate cancer, and over 2,500 die from it. While the issue of early detection of prostate cancer through the use of Prostate Specific Antigen test continues to raise debate, the longer term quality of life outcomes after treatment for this disease remain of great interest to patients, clinicians and health planners.

Each year more than 10,000 men are diagnosed with prostate cancer, and over 2,500 die from it. While the issue of early detection of prostate cancer through the use of Prostate Specific Antigen test continues to raise debate, the longer term quality of life outcomes after treatment for this disease remain of great interest to patients, clinicians and health planners. The Prostate Cancer Outcomes Study is an already established research project that was established in 2000 with the aim of documenting the quality of life outcomes of 2000 men with prostate cancer to five years after diagnosis. The Department of Veterans Affairs funded the study between 2000 and 2005, to establish the cohort, collect patterns of care information from clinicians and quality of life information from participants to 3 years post diagnosis. We are now seeking funds to complete the quality of life follow up for each surviving participant at five years after diagnosis. We also will assess rate of recurrence of prostate cancer to five years and seek support to be able to undertake linkage with death certificate information to determine the vital status of each study subject and begin analysis of five-year survival rates. Five-year quality of life information will be the main endpoint for this part of the study. Initial analysis of the three-year data showed a continued improvement in outcomes related to urinary and sexual function. We wish to determine whether these improvements continue to five years and the extent of the difference, at that time, between men with prostate cancer and men without prostate cancer (controls), whom we are also studying. This information will be uniquely useful in helping men make decisions about treatment options when diagnosed with prostate cancer.Read moreRead less
Defects of the internal and external genitalia are among the most common birth defects in babies (1 in 4,000 births) yet the aetiology in many cases is unclear. We will compare and contrast the mouse with a unique animal model the tammar wallaby to investigate the control of ovarian differentiation during early fetal and postnatal life. The gonad is unusual in that two completely different organs arise from the same precursor tissues, so that errors in development lead to intersexual phenotypes. ....Defects of the internal and external genitalia are among the most common birth defects in babies (1 in 4,000 births) yet the aetiology in many cases is unclear. We will compare and contrast the mouse with a unique animal model the tammar wallaby to investigate the control of ovarian differentiation during early fetal and postnatal life. The gonad is unusual in that two completely different organs arise from the same precursor tissues, so that errors in development lead to intersexual phenotypes. Some intersexual conditions are the result of inappropriate exposure to hormones during fetal life, and others are due to spontaneous or inherited gene mutations. About 5-10% of ovarian cancer cases, that affect 1 in 8000 Australian women, are due to the inheritance of a faulty gene. We will use comparative analysis and an inducible sex reversal system to understand the way gene expression and hence tissue differentiation is altered between male and female during the formation of the ovary versus the testis. This will inform us about the causes and consequences of normal and abnormal sexual development, infertility and gonadal malignancies.Read moreRead less

Summary
We know very little of the genes that control development of the ovary in female fetuses; most study has focused on the formation of the testis in males. We will use a novel experimental model, a marsupial, where by hormonal treatment of developing males we can switch off testis formation and activate the ovarian pathway. These studies will potentially shed new light on the causes of reproductive diseases including ovarian cancer, as well as clarifying the basic biological processes that guide f ....We know very little of the genes that control development of the ovary in female fetuses; most study has focused on the formation of the testis in males.

Summary
Achieving satisfaction in our intimate relationships is a vital component of our well being. To date, most studies of sexual and reproductive health have focused on how common particular problems might be. Thus, studies have tended to have relatively narrow focuses on, for example, the prevalence of pregnancy, miscarriage and termination, or on patterns of sexual practice and contraceptive use, or on the frequency with which individuals experience sexual difficulties. Yet, all of these are inter ....Achieving satisfaction in our intimate relationships is a vital component of our well being. To date, most studies of sexual and reproductive health have focused on how common particular problems might be. Thus, studies have tended to have relatively narrow focuses on, for example, the prevalence of pregnancy, miscarriage and termination, or on patterns of sexual practice and contraceptive use, or on the frequency with which individuals experience sexual difficulties. Yet, all of these are inter-related aspects of sexual and reproductive health that can have profound impacts on each other. Importantly, most of these studies have looked at these issues at a single point in time and could only infer the likely contribution of prior events on currently observed patterns. This study will recruit a random sample of Australians aged 16 to 65 years and interview them annually, initially over a four-year period. It will collect detailed information about sexual and reproductive health and provide essential information about how sexual and reproductive health changes as we age. It will document the relationships between patterns of sexual behaviour, contraceptive choices, pregnancy and its outcomes, and sexual functioning including the experience of sexual problems and the achievement of satisfaction in our physical and emotional intimate relationships.Read moreRead less

Summary
Ensuring the sexual and reproductive health of the Australian population is essential for our wellbeing as a nation. As well as the overall importance, at least three aspects of sexual and reproductive health are among the key policy issues for present Australian governments: maintaining and increasing the birth rate; reducing the abortion rate; and preventing and controlling Chlamydia infections.

Summary
Female sexual dysfunction (FSD) is frequently reported with selective serotonin reuptake inhibitor (SSRI) therapy and venlafaxine, these being the most common antidepressants used by Australian women. We have shown that testosterone therapy significantly improves sexual function in women with FSD. However SSRI-users have been excluded from these past studies. The aim of this study is to assess the efficacy of transdermal testosterone therapy for treatment of sexual dysfunction associated with SS ....Female sexual dysfunction (FSD) is frequently reported with selective serotonin reuptake inhibitor (SSRI) therapy and venlafaxine, these being the most common antidepressants used by Australian women.

MicroRNA Regulation Of Sex Determination And Gonad Development.

Summary
Sex determination, the decision to develop into either boy or girl, influences most aspects of our lives. Consequently, disorders of sexual development (~1% of births), resulting in genital abnormalities, infertility and often cancer, are extremely traumatic for the individual. The molecular basis of these disorders is not well understood. This project will identify new factors important for sex determination and therefore will improve diagnosis and clinical care for the patients.
