Preterm birth, a birth before the 37th week of pregnancy occurs for fewer than 8% of mothers but is associated with two-thirds of all fetal deaths and deaths of liveborn infants in the first month after birth.

In the late 1990s those deaths are concentrated among very preterm births i.e. births before the 32nd week of pregnancy. Infants born very preterm are very likely to need neonatal intensive care, quite likely to have had major respiratory, infectious or other problems after birth, and to need readmission to hospital in the first year after birth. Surviving infants are more likely to have major impairments, minor impairments, and school difficulties than infants born at term. There is a substantial impact on families, health services and society of very preterm birth.There has been no reduction in the proportion of births which are preterm, or very preterm in the last 20 years, though advances in treatment and care have markedly improved the survival of preterm and very preterm infants. This study will investigate the role of previous pregnancies which did not result in births (miscarriages and terminations), together with other procedures such as D and C (dilatation and curettage), in subsequent preterm birth. As these previous pregnancy losses are all fairly common experiences any associated risk is important and this particular factor has not been studied in this way before. There is preliminary evidence that they may be associated with preterm birth and the study will be able to measure the associations while taking into account all the other known risk factors. Other possible risk factors such as experiencing violence in pregnancy or social factors acting at a neighbourhood level will also be included. If it is found that previous pregnancy losses are independently associated with preterm birth it will be possible to develop and test preventive strategies.Read moreRead less

His clinical studies span male fertility regulation, the use of assisted reproductive treatments, and the evidence-based use of androgen replacement. As Director of Andrology Australia, he has a leading national role in professional and community education, developing research capacity and male health advocacy.
Role Of Stem-progenitor Cells In Endometrial Regeneration And Endometriosis

Summary
We have discovered 2 types of adult stem cells in the lining of the uterus (endometrium) that are likely responsible for its ability to grow a new lining each month. This project aims to determine if endometrial stem cells are shed into the pelvic cavity during menstruation to cause endometriosis, a common, chronic disorder affecting 6-15% of women during their reproductive years and for which treatments are suboptimal. This knowledge may change how endometriosis will be treated in the future.
Facilitating Endometrial Receptivity To Improve Pregnancy Outcomes

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.

Summary
Chlamydia is a common cause of sexually transmitted diseases resulting in pelvic inflammatory disease, infertility and ectopic pregnancy. There are no vaccines that prevent infection or disease. We have discovered a new factor in the immune system (interferon-epsilon) that only occurs in the reproductive tract. If this factor is absent then Chlamydia infections are more severe. We will investigate how this factor protects against infection and if we can use it as a new agent against Chlamydia ST ....Chlamydia is a common cause of sexually transmitted diseases resulting in pelvic inflammatory disease, infertility and ectopic pregnancy.

Summary
Defects in penis development are among the most common birth abnormalities, and affect around 1 in every 150 live male births in Australia. Development of the penis is known to be driven by male hormones (androgens), but we have recently shown that oestrogen also plays a role in this process. This project will define the role of estrogen in penis development and how a loss or gain of estrogens can cause developmental defects.
Role Of The Histone Variant H3.3 In Germ Cell Development

Summary
Over their life cycle, germ cells are unique in undergoing a large scale reformatting of their gene or DNA control systems, required for their own development, and for the development of the fertilized egg. We think that the protein ïhistone H3.3Í is crucial to this reformatting process. We will test this possibility by determining how much H3.3 is present in germ cells. Also, we will make mice which lack this protein in germ cells to see if this affects the reformatting process.
