Summary
~15% of couples are unable to have children. Their reliance on reproductive technologies (eg, IVF) has increased 4 fold over the past decade. One reason for infertility is that the lining of the uterus (endometrium) is not able to allow an embryo to attach – a key event in establishing healthy pregnancy. There is no test to assess whether the endometrium is ‘receptive’ to an embryo. We will develop special assays for a test and provide a basis for treatment without recourse to IVF.
Why Is There An Increased Risk Of Severe Adverse Perinatal Outcomes After The Use Of Clomiphene Citrate For Infertility Treatment?

Summary
Clomiphene citrate (CC) has been a first line treatment for female infertility internationally since the 1960’s. However, safety studies using routine prescribing practices were never performed, and numerous data sources now indicate that CC is associated with major adverse outcomes if the fetus is inadvertently exposed. We are linking prescription data to perinatal outcomes to confirm how CC is associated with adverse events so as to inform prescriber and practice change.
Identifying Strategies To Improve Perinatal Outcomes After Assisted Conception

Funding Amount

Summary
Around 20% of young women express concern with being able to conceive, 16% experience clinical infertility, and ~8% use invasive therapies for which there can be limited safety data. We, and others, have reported adverse events for mother and child after infertility treatment, including neonatal death and birth defects. This project will provide urgently needed, robust evidence to guide patient and clinical decision making so as to optimise health of mother and baby.
Mechanisms Of DNA Damage-induced Oocyte Apoptosis And Infertility: Examination Of The Role Of BH3-only Proteins.

Summary
Our ability to prevent or postpone menopause following cancer treatment, is of great importance for female fertility, health and quality of life. We will demonstrate that the death gene of the Bcl-2 family of life and death genes, Puma, is responsible for killing female germ cells after damaging treatment. When Puma is absent, sufficient high quality germ cells are able to survive damaging treatment, allowing normal fertility in mice. The quality of these rescued germ cells will be analysed in d ....Our ability to prevent or postpone menopause following cancer treatment, is of great importance for female fertility, health and quality of life.

Medically Assisted Fertility Treatment And Infant Outcomes: The Role Of IVF (in Vitro Fertilisation), Ovulation Induction And Subfertility

Funding Amount

Summary
Medically assisted fertility treatment such as IVF and fertility medications account for the birth of at least one in 25 children born in Australia. While the health outcomes of these children are reassuring there is a lack of conclusive findings on the clinical role of IVF and non-IVF treatments and on their safety, particularly the newer forms of IVF. This research will fill this evidence gap, informing patients and clinicians on the safety and effectiveness of fertility treatments.
Accountable Fertility Treatment: An Evidenced-based Framework For The Provision Of Cost-effective, Patient-centred Fertility Treatment In Australia.

Funding Amount
$423,312.00
Summary
One in six Australian couples experience infertility. This is likely to worsen with trends such as delayed childbearing and rising obesity. Despite the use of fertility treatments doubling in Australia over the last decade there has been a lack of considered analysis of the economic implications of Medicare funding of treatments, such as IVF. This research will develop a framework that will be used by policy makers to support cost-effective and patient-centred fertility treatment in Australia.
This research program entitled Stem cells from the testis is designed to use cutting edge molecular and cellular biology techniques to isolate adult stem cells from the testis. These stem cells will be expanded in cell culture and tested for therapeutic activity in mouse models of infertility, leukaemia and kidney failure. The knowledge and techniques developed in the mouse system may help unlock the potential of human cell based therapies for these and other degenerative diseases.

Endometrial Receptivity For Embryo Implantation: Proprotein Convertase 6 And Plasma Membrane Remodeling
Funder
National Health and Medical Research Council
Funding Amount
$631,344.00
Summary
Implantation of an embryo into the uterus is a key step in establishing pregnancy; it requires a receptive uterus (fertile soil) and a healthy embryo (seed). Implantation failure causes pregnancy loss and infertility, and is also a major limiting factor in IVF. We have established that proprotein convertase 6 (PC6) is a master regulator of uterine receptivity for implantation. We will investigate how PC6 works in a woman’s uterus, and how we can use this knowledge to improve implantation in IVF.
Leucine-rich Guanylate Kinase Is A Regulator Of Sperm Tail Development And Motile Cilia Function

Funding Amount
$540,191.00
Summary
In this grant we will define the function of an uncharacterized protein, LRGUK, in fertility and hydrocephalus (water on the brain). LRGUK has a critical role in sperm development. We will define the cell biology and biochemistry of LRGUK function, we will assess the incidence of LRGUK mutations in human fertility and explore LRGUK function in the brain. Data obtained will have relevance to the 1 in 20 young men who suffer from infertility and the 3 in 1000 children who develop hydrocephalus.
