This study is aiming to develop an unique mouse model in which to study the question whether testosterone plays an essential role in female reproductive and general health. It will develop a genetic mouse model for a biological state of complete resistance to the effects of androgens. Such mice and humans are well known among genetic males but this cannot occur naturally among genetic female mammals.

Such mice and humans are well known among genetic males but this cannot occur naturally among genetic female mammals.

Fetal And Genetic Origins Of Polycystic Ovary Syndrome (PCOS) In Young Women

Summary
Polycystic ovary syndrome (PCOS) is a common hormonal condition which emerges at puberty and afflicts up to 10% of women. The cause of PCOS is uncertain. Symptoms include menstrual disorders, acne, obesity, and excess body hair. PCOS is of great significance for women because of the high incidence of infertility and the high risk of other serious diseases, including diabetes mellitus and endometrial cancer. PCOS is probably the most common hormonal condition among young women.

Symptoms include menstrual disorders, acne, obesity, and excess body hair. PCOS is of great significance for women because of the high incidence of infertility and the high risk of other serious diseases, including diabetes mellitus and endometrial cancer. PCOS is probably the most common hormonal condition among young women. The cause of PCOS is unknown and the relationship between PCOS and the more common condition of polycystic ovaries, which often features in PCOS, is uncertain. There is evidence that genetic factors contribute to PCOS, but cannot explain certain aspects. There is also striking new evidence that abnormal growth in the womb can alter the metabolism of the baby for life, resulting in increased risks of adult disease, including diabetes and cardiovascular disease. PCOS may be another consequence of abnormal fetal growth, a suggestion that is supported by two recent studies of closely related conditions. To investigate the origins of PCOS, we propose to establish the first international study of the relationships between fetal growth, genetic factors and the presence of PCOS. In this study, we shall trace 3,260 women born in one maternity ward during 1973-75. These women, now young adults, will be invited into our study for an interview, physical examination, and a blood test. We expect 2,200 women will participate. Of this group, some 220 women with PCOS will receive further tests to investigate a range of metabolic problems. The study has the potential to illuminate the path from genetic predisposition and fetal growth, to the emergence of an important reproductive disorder with serious associated diseases in a woman s later life.Read moreRead less
Discriminating The Roles Of Inhibin A And B In Reproductive Systems

Summary
Inhibin A and B are essential for the regulation of fertility based on their dual inhibitory actions on follicle stimulating hormone secretion by the pituitary and egg and sperm production in the gonads. An understanding of the mechanisms involved in inhibin A and B actions will: (1) identify novel biomarkers for the diagnosis of reproductive disorders (2) enhance the management of reproductive disorders (3) identify targets for the development of therapeutic means of modulating fertility
Robert McLachlan is an internationally recognised clinician-scientist in male reproductive health. His basic research examines the genetic & endocrine regulation of sperm production. 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.
Many different diseases can cause chronic kidney failure. Mast cell participation in most of these is prominent. These cells traditionally regarded as important only in allergy are now known to be capable of inducing injury in many other situations. The availability of safe drugs to block mast cell function makes determination of the role of mast cells in chronic kidney diseases important.
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.

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.
