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.

Summary
Muscle wasting is associated with increased risk of death in patients with liver disease. Many factors contribute to this muscle wasting, but our group’s recent finding that testosterone therapy increases muscle mass in men with liver disease remains the only proven treatment. This project aims to increase understanding of the causes of muscle wasting and to show that testosterone treatment improves clinical outcomes, which could improve the health of liver disease sufferers worldwide.
Mechanisms Of Negative Feedback Regulation Of GnRH By Testosterone In Males

Summary
This project will improve our knowledge of the hormonal control of reproduction in males. The hormone testosterone, produced by the testes, acts on the brain to control the secretion of a substance called gonadotrophin releasing hormone (GnRH). GnRH acts on a small gland at the base of the brain to cause the production of hormones called gonadotrophins, that are essential for reproduction. These gonadotrophins act on the testes to ensure the production of sperm and other hormones, including test ....This project will improve our knowledge of the hormonal control of reproduction in males. The hormone testosterone, produced by the testes, acts on the brain to control the secretion of a substance called gonadotrophin releasing hormone (GnRH). GnRH acts on a small gland at the base of the brain to cause the production of hormones called gonadotrophins, that are essential for reproduction. These gonadotrophins act on the testes to ensure the production of sperm and other hormones, including testosterone. We plan to determine how testosterone acts on the brain to control GnRH secretion. To do this we will use male sheep and conduct a series of experiments designed to show where in the brain testosterone acts to ultimately affect the nerve cells that produce GnRH. Testosterone and similar compounds are increasingly being used as treatments for infertility, as a male contraception and misused as anabolic steroids. A thorough knowledge of how testosterone acts in the brain is necessary to improve treatments for reproductive disorders and ultimately to improve reproductive health in men.Read moreRead less
Effect Of Testosterone Treatment Combined With Dietary Restriction On Body Fat Mass And Muscle Function In Obese Men: A Randomized Controlled Trial

Funding Amount
$140,949.00
Summary
Obesity, an increasing health and economic burden, is associated with lowered testosterone levels in men. While both dietary restriction and testosterone treatment reduce body fat, whether a combination of these two approaches achieves a more pronounced fat mass reduction is unknown. We will conduct a rigorous 12 month clinical trial of testosterone treatment in 150 obese men with a low testosterone level. All men will receive dietary intervention to induce and maintain weight loss
Dissecting Associations Of Estradiol And Testosterone With Cardiovascular Outcomes.

Funding Amount
$435,082.00
Summary
Controversy persists over whether falling testosterone (T) levels in ageing men increase risk of cardiovascular disease (CVD). T is converted by the enzyme aromatase into estradiol (E2). We will assess whether men with abnormal E2 levels are at risk of CVD, more so than men with low T. We will assess whether differences in the aromatase gene which alter E2 levels also influence the risk of CVD. The results will clarify the importance of hormones to CVD and guide new approaches to its treatment.
Control Of Musculoskeletal Function And Glucose Metabolism By Androgens In Men

Summary
Male sex hormone or androgen deficiency (AD) is a common, but under-diagnosed condition. AD decreases general well being and contributes to muscle weakness, bone fragility and weight gain. By using cutting edge imaging and molecular technologies, we will help to explain the underlying mechanisms of how AD leads to these negative effects. This should ultimately lead to reduction of adverse outcomes of AD, which include fractures and cardiovascular events.
