The Australian Research Data Commons (ARDC) invites you to participate in a short survey about your
interaction with the ARDC and use of our national research infrastructure and services. The survey will take
approximately 5 minutes and is anonymous. It’s open to anyone who uses our digital research infrastructure
services including Reasearch Link Australia.
We will use the information you provide to improve the national research infrastructure and services we
deliver and to report on user satisfaction to the Australian Government’s National Collaborative Research
Infrastructure Strategy (NCRIS) program.
Please take a few minutes to provide your input. The survey closes COB Friday 29 May 2026.

Markers Of Androgen Action, Genetic Variation And Prostate Cancer Risk

Summary
This proposal aim to follow up evidence from a number of studies that genetic and non-genetic markers of hormonal action in different periods of a man's life are associated with prostate cancer risk using a collection of three large, independent epidemiologic studies on prostate cancer named the Prostate Cancer Program. A principal objective is to collect exposure data on acne and digit ratio, and genotype cases and controls across the studies of the Prostate Cancer Program for common genetic va ....This proposal aim to follow up evidence from a number of studies that genetic and non-genetic markers of hormonal action in different periods of a man's life are associated with prostate cancer risk using a collection of three large, independent epidemiologic studies on prostate cancer named the Prostate Cancer Program. A principal objective is to collect exposure data on acne and digit ratio, and genotype cases and controls across the studies of the Prostate Cancer Program for common genetic variants in 4 candidate genes in the hormonal pathway. The established risk factors for prostate cancer are only age, race and family history. We anticipate that this project will cast light on the role of hormones in prostate cancer and that we will identify new markers of risk of prostate cancer and markers of disease aggressiveness. These outcomes will help us identifying men who are at risk for prostate cancer to target screening and surveillance, and plan prevention strategies. Furthermore, they will also form the basis for research on treatment targets.Read moreRead less
Obstructive Sleep Apnea And Androgen Dysregulation
Funder

Funding Amount
$537,041.00
Summary
Obstructive Sleep Apnea (OSA) is a serious public health problem associated with increased sleepiness, heart disease and metabolic dysfunction. Obesity and male gender are important predisposing factors for OSA. This study will determine if short-term testosterone therapy can help improve OSA in men who are also dieting and exercising. It will also determine the genetic mechanisms by which testosterone might influence breathing during sleep and obesity.
I am a clinician-scientist with a focus on basic and translational research in male reproductive physiology and health disorders, notably infertility, contraception and androgen action.
Regulation Of Immune Responses In The Adult Testis And Male Reproductive Health
Funder
National Health and Medical Research Council
Funding Amount
$637,857.00
Summary
This project investigates the main inflammatory cell, the macrophage, in male fertility and reproductive health. These studies investigate the macrophages found in the testes and the regulation of their functions required to protect and support the developing sperm. Understanding these processes will lead to new methods for treating male infertility, chronic pain and reproductive tract infections, as well as broader understanding of inflammatory disease, transplantation and autoimmunity.
This program will expand research and policy development to overcome androgen misuse (off label testosterone prescribing for invalid indications) and combat androgen ('anabolic steroid') abuse for performance and image enhancement. Beyond expanding ongoing research, it will develop a new focus in developing drugs to accelerate recovery from androgen abuse, thereby preventing relapse during the slow natural recovery period typically lasting 6-18 months or longer
Hormonal Responsive Coding And Non-coding Genes In Penile Differentiation And Hypospadias
Funder
National Health and Medical Research Council
Funding Amount
$835,182.00
Summary
Hypospadias, a failure of the correct formation of the penis, is the second-most common birth defect, occurring in around 1% of boys. It causes distress to both newborn and parents, requiring surgical intervention, and is a burden of cost and is a risk to the child. Furthermore, it is frequently associated with other abnormalities. We have a novel model in which we can induce penis abnormalities and define the link between hormonal exposures and defective penis differentiation.
