This project is about the way that the brain controls reproduction. It is important because there is no known cause for infertility in a significant number people with such a problem. The project should inform us on new ways to manage particular forms of reproductive failure.
Gonadotropin Inhibitory Hormone (GnIH); A Negative Regulator Of Reproduction
Funder
National Health and Medical Research Council
Funding Amount
$752,936.00
Summary
Gonadotropin inhibitory hormone (GnIH) is a short peptide of 8 amino acids that is produced by the brain and acts in a negative manner on brain and pituitary cells that control reproduction. This project aims to elucidate the role of GnIH in normal physiology and in states of stress and negative metabolic state. Work will be carried out in various species to define the function of the peptide and also to investigate ways that it can be utilised to prevent reproduction.

Summary
Achieving the goal of reproductive health for all is a public health issue and is limited by factors including, problems of infertility, inadequacies of the fertility-regulating methods and the high incidence of reproductive tract diseases, including cancers. The overall objective of this Program Grant is to discover, understand and apply new knowledge about reproductive processes in health and disease to alleviating infertility, improving contraceptive choice and efficacy and combating diseases ....Achieving the goal of reproductive health for all is a public health issue and is limited by factors including, problems of infertility, inadequacies of the fertility-regulating methods and the high incidence of reproductive tract diseases, including cancers. The overall objective of this Program Grant is to discover, understand and apply new knowledge about reproductive processes in health and disease to alleviating infertility, improving contraceptive choice and efficacy and combating diseases in the reproductive organs.Read moreRead less
Disorders of sexual development are among the most common form of birth defects in humans (1 in 4,000 births) because failure of the gonads to develop does not affect the viability of the individual. Such disorders can have profound psychological and medical consequences upon the individual, family, and society. Some intersexual conditions are the result of inappropriate exposure to hormones during fetal life, and others are due to spontaneous or inherited gene mutation. About 5-10% of ovarian c ....Disorders of sexual development are among the most common form of birth defects in humans (1 in 4,000 births) because failure of the gonads to develop does not affect the viability of the individual. Such disorders can have profound psychological and medical consequences upon the individual, family, and society. Some intersexual conditions are the result of inappropriate exposure to hormones during fetal life, and others are due to spontaneous or inherited gene mutation. About 5-10% of ovarian cancer cases, that affect 1 in 8000 Australian women, are due to the inheritance of a faulty gene. An understanding of the way gene expression and hence tissue differentiation is altered after sex reversal will inform us about the causes and consequences of normal and abnormal sexual development, gonadal malignancies and infertility. The gonad is unusual in that two completely different organs can arise from an essentially identical primordium, so that errors in development lead to intersexual phenotypes. We will use our new experimental animal model to clarify these processes.Read moreRead less
