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.

Exercise In Males Born Growth Restricted To Restore Sperm Function Preventing Adverse Offspring Health

Funding Amount

Summary
Males born growth restricted transmit heart disease and diabetes to their children. The mechanism of this transmission is unknown, but is likely due to altered sperm function. We aim to determine the impact growth restriction has on sperm function in men and rats, and establish the optimal window for rat exercise intervention to prevent disease transmission. We expect that exercise in juvenile life will prevent, whereas exercise in adults may ameliorate disease outcomes by improving the sperm.
The Negative Transgenerational Impacts Of Paternal Obesity Are Inherited Through Aberrant Methylation And MicroRNA Conetent Of Germ Cells.

Funding Amount
$307,946.00
Summary
We have shown that obese fathers have reduced sperm function that negatively impacts upon their offspring’s health. But we do not understand the underlying alterations to sperm DNA that cause offspring to inherit poor health from an obese father, and whether these offspring also exhibit the same alterations. My project aims to identify alterations made to sperm DNA and RNA caused by obesity that are inherited by the next generation, ‘programming’ them for poor metabolic and reproductive health.
The Obesity Prone Oocyte- Causes, Consequences, Treatments
Funder

Funding Amount
$516,159.00
Summary
Obesity is perpetuated from mothers to offspring, in part due to changes in the oocyte (egg) that affect embryo growth. We have discovered that obesity causes changes in the mitochondria (the energy producers) of the egg. We hypothesise this causes long-lasting changes to embryo metabolism and will test, in mice, novel treatments to reverse the detrimental effects. The project will show how obesity affects embryo metabolism and growth, and determine whether defects can be prevented by drugs or l ....Obesity is perpetuated from mothers to offspring, in part due to changes in the oocyte (egg) that affect embryo growth.
