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.

Monogamy As An HIV And STI Prevention Strategy For Gay Men
Funder
National Health and Medical Research Council
Funding Amount
$407,506.00
Summary
Monogamy is relatively common among Australian gay men and yet relatively under researched or explored. At present we know little about the motivations of Australian gay men to enter and maintain monogamous relationships. This study will bring into clear view a phenomenon, and social and intimate practice, that has been almost entirely overlooked and will significantly advance our understanding of the dynamics of gay men's sexual behaviour and sexual cultures.
Sex Hormones And Heart Disease In Older Women Study (The SHOW Study)
Funder
National Health and Medical Research Council
Funding Amount
$594,672.00
Summary
Cardiovascular disease (CVD, heart disease and stroke) is the leading cause of death in women aged 65 and over. Counter-intuitively, androgens may be as, or even more important, than estrogens in determining CVD risk and all-cause mortality in women, but this is yet to be verified. We will document blood levels of androgens in women aged 70+ and determine whether androgens are associated with CVD and death in this large cohort of elderly well women.
Hypospadias, is a common defect, in which the urethra opens abnormally along the shaft of the penis not at the tip. It affects 1 in every 125 boys born in Victoria each year. However, the cause(s) of over two-thirds of these cases cannot be explained. Our studies using marsupials show that this process is mediated by a hormone (5alpha-androstanediol), with previously undetermined physiological function. This study will provide novel data on the interactions of the genes and hormones that result ....Hypospadias, is a common defect, in which the urethra opens abnormally along the shaft of the penis not at the tip.

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.
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.
The Role Of Androgens In Cardiovascular Repair And Regeneration
Funder
National Health and Medical Research Council
Funding Amount
$464,468.00
Summary
Increasing evidence indicates that the heart and blood vessels are able to repair themselves in response to disease. Recent evidence suggests that in men, male sex hormones(e.g. testosterone) may play an important role in helping repair blood vessels. As men get older, their testosterone levels get progressively lower - this lead to impairment of vascular repair mechanisms with aging. We will study the effects of androgens on repair and regeneration of the vasculature.
Identifying Castrate-resistant Tumour Cells In Localised Prostate Cancer
Funder
National Health and Medical Research Council
Funding Amount
$573,047.00
Summary
This proposal addresses one of the most important challenges in cancer: what cell population ‘drives’ tumour progression, and how can it be effectively targeted? We will define the prostate cancer cells that survive androgen withdrawal therapy and investigate new ways to target them. Eliminating these important cells earlier in disease progression will lead to increased survival for men with prostate cancer.
Prostate cancer is the most common cancer in men, causing about 3,300 deaths per year. We have identified some small RNAs called microRNAs and other hormone regulators that can interfere with prostate cancer cell growth and signaling via the testosterone pathway. In this application we will be exploring the potential for each of these agents to reduce prostate cancer growth and the possibility that one or more could develop into a therapeutic target in the future.
The Role Of Androgens In Burn Injury Wound Healing
Funder
National Health and Medical Research Council
Funding Amount
$439,480.00
Summary
Burn injury is a major cause of morbidity and mortality. Over 10,000 individuals are affected by severe burns each year in Australia. This innovative project aims to provide new fundamental knowledge about the role of androgens (male hormones) in complex burn injury wound healing process, also provide pre-clinical evidence of the ability to systemic and/or local target androgen signaling to improve wound healing for severe burn injury patients.
Explaining Social Preferences For Priority Setting In The Health Sector
Funder
National Health and Medical Research Council
Funding Amount
$235,218.00
Summary
This project looks at whether the views of the public regarding the allocation of society's limited health care resources are well-informed and carefully considered. A series of focus groups will be conducted where members of the public can think about the ethical issues involved, discuss them with others, and ask questions. This approach has the potential to improve the legitimacy of health policy decisions by contributing to a better understanding of the values of the public.
