Funding Amount
$481,563.00
Summary
Male infertility is an extremely common condition, that is frequently associated with the production of sperm that have lost their ability to recognize the egg. We have shown that this defect is frequently associated with a deficiency in a specific protein (HSPA2). By determining the mechanisms underpinning the loss of HSPA2, this project will provide powerful insights into the causes of male infertility, with practical implications for prevention, diagnosis and treatment of this condition.
Novel Function Of Heat Shock Protein 2A In The Regulation Of Human Sperm-egg Interactions

Funding Amount

Summary
Male infertility is an extremely common condition affecting around 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. In this project we shall investigate whether this defect is due to a deficiency in a specific protein (HSPA2). This project will provide new and powerful insights into the causes of male infertility, with practical implications for prevention, diagnosis and treatment of this condition.
Embryo implantation is a critical step in establishing pregnancy, requiring stable attachment of an embryo to the uterus. For this to occur, the embryo must be implantation competent and the uterus must be receptive. However, to date, little is known about the interactions between the two that determine a successful implantation in the human. This project will investigate a novel embryo-derived enzyme that drives human implantation. These studies are important to improve infertility treatment.
The Role Of Dynamin In Spermatogenesis, Sperm Maturation And Sperm-oocyte Interactions

Funding Amount
$551,950.00
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 interact with the egg and penetrate its outer vestments. In this project we shall investigate the role of dynamin in the regulation of these events. This research will provide new and powerful insights into the causes of male infertility, with practical implications for diagnosis and treatment of this condition.
The Role Of MiRNAs In The Regulation Of Sperm Maturation

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.
Understanding Idiopathic Male Infertility: Biomarkers To Assist In The Diagnosis And Assisted Reproductive Technology Outcomes

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.
A BubR1-centred Network For Non-invasively Measuring Human Oocyte Quality

Funding Amount
$532,207.00
Summary
Oocyte quality is the most important determinant of pregnancy outcome. Selecting the best oocytes for fertility treatments like IVF would therefore greatly improve success rates and reduce costs. We have identified master oocyte regulators and have applied novel digital technology to measure these regulators in a single oocyte. This project will apply this expertise to develop new approaches for evaluating an oocyte’s potential thereby informing its suitability for use in fertility treatment.

Summary
Infertility is common and although IVF is widely accepted, the procedure is expensive and is associated with health risks. Using laboratory animals, we have developed significant new insights into mechanisms regulating egg quality. These insights have allowed us to develop a new approach to infertility treatment - crucially, one that eliminates the need for ovarian hormone therapy used in IVF. This project will investigate the basic mechanisms underlying our new approach to enable safe clinical ....Infertility is common and although IVF is widely accepted, the procedure is expensive and is associated with health risks.
