Summary
We discovered and manufactured a growth factor produced uniquely by the egg. We named this growth factor cumulin. It is a powerful regulator of ovarian function and egg quality. This project will study the basic mechanisms of how cumulin works in the ovary. We will then develop an assay to measure it as a biomarker of human egg quality and quantity. New approaches in fertility preservation for cancer survivors will be developed using cumulin.
Activation Of GDF9 Regulates Human Folliculogenesis

Summary
GDF9 is a key regulator of fertility in female mammals, as it controls the process of folliculogenesis. In this grant, we will demonstrate the importance of GDF9 in human folliculogenesis, determine the mechanisms that activate GDF9 and show why aberrant GDF9 activation leads to ovarian disorders. Collectively, the outcomes of this proposal will increase our understanding of the fundamental mechanisms that regulate ovarian folliculogenesis and provide new avenues to manipulate this process.
The Importance Of The Blood-testis Barrier In Human Infertility

Summary
The blood-testis barrier (BTB) shields developing sperm from the circulation and immune system, which would see them as ‘foreign’. Loss of BTB function leads directly to infertility. Curiously, how the BTB ‘opens’ and ‘closes’ to allow entry without causing a ‘leak’ is unknown. We believe that activin A is the main gatekeeper, but this growth factor is also important in inflammation. Our goals are to show how activin A allows sperm cells entry, and how inflammatory diseases impact the BTB.
Exercise In Males Born Growth Restricted To Restore Sperm Function Preventing Adverse Offspring Health

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 Long-term Consequences Of Assisted Reproduction On The Growth, Metabolic, Respiratory, Psychological, Immunological And Reproductive Development Of The Offspring.

Summary
1 in 25 children are born from IVF treatment - incredibly- to our shame; no data exists as to the long-term health of these children. Presented is a unique opportunity, which would be exceedingly difficult to replicate elsewhere in the world, to determine the long-term consequences of IVF upon the development of the offspring, by comparing their growth, metabolic, respiratory, psychological, immunological and reproductive development to a representative sample of WA children- the Raine cohort.
