This project is about the way that the brain controls reproduction. It is important because there is no known cause for infertility in a significant number people with such a problem. The project should inform us on new ways to manage particular forms of reproductive failure.
Gonadotropin Inhibitory Hormone (GnIH); A Negative Regulator Of Reproduction
Funder
National Health and Medical Research Council
Funding Amount
$752,936.00
Summary
Gonadotropin inhibitory hormone (GnIH) is a short peptide of 8 amino acids that is produced by the brain and acts in a negative manner on brain and pituitary cells that control reproduction. This project aims to elucidate the role of GnIH in normal physiology and in states of stress and negative metabolic state. Work will be carried out in various species to define the function of the peptide and also to investigate ways that it can be utilised to prevent reproduction.
Male-female Sperm Signalling - A Novel Pathway For Peri-conceptual Health?
Funder
National Health and Medical Research Council
Funding Amount
$674,920.00
Summary
This project will investigate a new biological process in reproduction, whereby sperm delivered to the cervix at coitus transmit signalling molecules called microRNAs that influence the female immune response, to increase the chances of conception and pregnancy. We will define the molecular details of this signalling pathway in mouse models, and then determine whether human sperm have a comparable function in ‘priming’ the female body to conceive.
Facilitating Endometrial Receptivity To Improve Pregnancy Outcomes

Funding Amount
$734,252.00
Summary
The womb prepares itself in each menstrual cycle for pregnancy and the implantation of an embryo. In some women, the endometrium may not prepare itself adequately and this can lead to infertility. We have identified small RNA that may be useful in predicting which women are not adequately prepared for implantation and may be used to develop treatments for infertile women, for which there are currently no treatments.
Epigenetic Regulation Of Male Fetal Germ Cell Development.

Funding Amount
$562,176.00
Summary
Men’s health has declined over recent decades, but the causes remain unknown. Non-genetic (epigenetic) mechanisms affecting formation and function of the male germ cells (which produce sperm) may play an important role. We will determine the role of a key epigenetic modifier on the formation and function of male germ cells, including germ cell tumours. This study will provide fundamental insights into male germ cell epigenetics, and significantly contribute to understanding men's health.
Activin And Its Binding Protein, Follistatin Regulate Functions Of The Epididymis And Vas Deferens
Funder
National Health and Medical Research Council
Funding Amount
$612,736.00
Summary
Male reproductive disease is a serious health issue for many men and their partners. Worldwide, malformations of the male reproductive organs are increasing, infections and chronic inflammation of the genitourinary tract beset sexually active men and aging men, and infertility afflicts one in seven couples desiring children. The causes underlying these conditions are not well-understood. These studies are intended to identify new approaches for preventing and treating these conditions.
Female Reproductive Health Preservation By Nicotinamide Adenine Dinucleotide (NAD+) And Sirtuin2 (SIRT2)
Funder
National Health and Medical Research Council
Funding Amount
$410,983.00
Summary
Cancer treatment can be severely toxic to women’s eggs. Increasing numbers of women who survive cancer therefore become infertile and prematurely deprived of hormonal support whilst still in their reproductive years. This project will use state-of-the-art techniques to interrogate newly uncovered pathways that can protect eggs from treatment-induced injury thereby greatly improving the quality of life for female cancer survivors.
The Role Of MiRNAs In The Regulation Of Sperm Maturation
Funder
National Health and Medical Research Council
Funding Amount
$396,157.00
Summary
Male infertility is an extremely common condition affecting 1 in 20 Australian men. One of the major reasons for this pathology is that the spermatozoa have lost their ability to recognize the egg, a function that is acquired during epididymal maturation. In this project we shall investigate the regulation of epididymal sperm maturation and thus provide new and powerful insights into the causes of male infertility, with practical implications for diagnosis and treatment of this condition.
Interferon Epsilon, A Key Cytokine In The Pathophysiology Of The Female Reproductive Tract Mucosa
Funder
National Health and Medical Research Council
Funding Amount
$793,303.00
Summary
The female reproductive tract is a complex environment, which permits pregnancy but protects against infections, all under the influence of hormones and the resident microbial flora. We have discovered a novel protein called interferon epsilon that acts on cells in the female reproductive tract to regulate protection against infections. We aim to discover how this new protein works and will determine its therapeutic potential in infections and inflammatory diseases affecting women's health.
Understanding Idiopathic Male Infertility: Biomarkers To Assist In The Diagnosis And Assisted Reproductive Technology Outcomes
Funder
National Health and Medical Research Council
Funding Amount
$411,012.00
Summary
In order to help in the diagnosis of male infertility, we have found several biomarkers that can be readily and quickly used to determine if a mans spermatozoa are infertile. Not only will this save time and money for couples involved in IVF, but help to avoid unnecessary, often invasive medical procedures that are currently used.
