Summary
A surprising feature of our body is that there is not enough blood to fully supply all our organs at once. This is why we sometimes faint when we are hot or get cramps when we are exercising. Consequently, the blood vessels change their diameter so that blood can be directed to the organs with greatest demand at any particular time. For example, if the vessel decreases in diameter, less blood flows through it, but if it increases in diameter, more blood flows through it to reach the appropriate ....A surprising feature of our body is that there is not enough blood to fully supply all our organs at once. This is why we sometimes faint when we are hot or get cramps when we are exercising. Consequently, the blood vessels change their diameter so that blood can be directed to the organs with greatest demand at any particular time. For example, if the vessel decreases in diameter, less blood flows through it, but if it increases in diameter, more blood flows through it to reach the appropriate organ. An important function of the nervous system is to control the flow of blood to different organs by changing the diameters of the blood vessels. One set of nerves decreases the diameter of the arteries, and another set of nerves increases the diameter. The nerves do this by releasing special combinations of chemicals when they get a message from the brain to do so. In this project we are especially interested in the nerves which increase blood flow to organs in the head and the pelvis. We will use a wide range of modern methods to find out how these nerves work. In some experiments, we will use sophisticated electrical equipment to measure just how the nerve cells controlling the diameter of the vessels respond to the instructions sent by the brain. In other experiments, we will find out which chemicals the nerves use to make the blood vessels increase in diameter. We also will discover how the various chemicals get released by the nerves at the right times, so that messages from the brain get to the blood vessels as efficiently as possible. One of the special parts of our project is that we will be able to observe directly the connections between the nerve cells and the blood vessels we are studying. Our results will be important for designing new drugs that could help people whose nerves are not working properly, such as in some patients with diabetes or vascular disease.Read moreRead less
Transdermal Testosterone Therapy: A Potential Treatment For Selective Serotonin Reuptake Inhibitor (SSRI)-associated Sexual Dysfunction In Women

Summary
Female sexual dysfunction (FSD) is frequently reported with selective serotonin reuptake inhibitor (SSRI) therapy and venlafaxine, these being the most common antidepressants used by Australian women. We have shown that testosterone therapy significantly improves sexual function in women with FSD. However SSRI-users have been excluded from these past studies. The aim of this study is to assess the efficacy of transdermal testosterone therapy for treatment of sexual dysfunction associated with SS ....Female sexual dysfunction (FSD) is frequently reported with selective serotonin reuptake inhibitor (SSRI) therapy and venlafaxine, these being the most common antidepressants used by Australian women.

Changes In Pelvic Autonomic Neurons After Spinal Nerve Injury

Summary
This project is about the effects of spinal injury on autonomic neurons that control the bladder, lower bowel and reproductive organs. One of the consequences of some types of spinal injury is that there are no signals being sent from the spinal cord to the nerve cells outside the cord, and this leads to poor bladder control, impotence, etc. We are mimicking this problem experimentally by damaging the spinal nerves that carry these signals. We have found that after this type of damage the pelvic ....This project is about the effects of spinal injury on autonomic neurons that control the bladder, lower bowel and reproductive organs. One of the consequences of some types of spinal injury is that there are no signals being sent from the spinal cord to the nerve cells outside the cord, and this leads to poor bladder control, impotence, etc. We are mimicking this problem experimentally by damaging the spinal nerves that carry these signals. We have found that after this type of damage the pelvic autonomic neurons make many new connections between each other, and the types of new connections depend on which spinal nerves have been injured. This leads to the question: are these new connections good or bad? ie are they helpful in trying to get organ control back to normal or will they stop the correct connections from the spinal cord from being made in the future? This project addresses these questions by using sophisticated techniques for staining and visualising individual nerve fibres growing out from the spinal cord. We will track how well these fibres grow back and connect with the pelvic autonomic neurons. In particular, we will see whether they make correct connections, and if these connections are influenced by the new fibres that have grown between the autonomic neurons in the interim period. We will also do physiological tests to see if the new connections have the correct function. The ultimate aim of these studies is not only to understand more about regeneration, but to see what determines whether the correct connections have been made - and ideally, to give us insight into how we can make regeneration work more quickly and accurately. We believe that this work is an important adjunct to other studies on spinal injury, which mostly focuses on regaining voluntary motor control (e.g. walking); however loss of bladder, bowel and reproductive function is another important quality of life issue for spinal injury patients.Read moreRead less

Summary
Ensuring the sexual and reproductive health of the Australian population is essential for our wellbeing as a nation. As well as the overall importance, at least three aspects of sexual and reproductive health are among the key policy issues for present Australian governments: maintaining and increasing the birth rate; reducing the abortion rate; and preventing and controlling Chlamydia infections.
Randomised Controlled Trial Of Early Intervention To Improve Sexual And Couple Functioning After Prostate Cancer

Funding Amount
$405,000.00
Summary
Treatment for localised prostate cancer has a long term negative impact on the sexuality, quality of life, and relationship quality of Australian men and their intimate partners. This study will trial a remote access couples based sexuality intervention for this patient and carer group that has potential for broader translation into community and acute health care settings. This approach will also have broader application for chronic disease self management for other health conditions.

TGFB1 Is A Pivitol Regulator Of Endometriotic Lesion Development

Summary
Endometriosis occurs when the tissue that lines the womb is found in the pelvic cavity. 10% of reproductive aged women have endometriosis and suffer from debilitating pelvic pain and subfertility. We have shown that transforming growth factor (TGFB1) is central to the growth of endometriosis and that its absence suppresses disease development. We hope to clarify the role of TGFB1 in endometriosis, in order to develop better therapeutic options for women incapacitated by this disease.
