Summary
Assisted reproductive technologies result in a high incidence of multiple births. This is and adverse outcome that requires correction. It stems from the common transfer of several embryos due to the low chance of an individual embryo made by IVF resulting in a baby. This project will determine the normal pattern of gene expression in the embryo and define: (1) how it is adversely changed as a consequence of IVF; and (2) the extent that these changes are a cause of the low embryo viability.
Mechanisms Of P53 Induced Embryopathy After In Vitro Fertilisation.

Summary
Assisted reproductive technologies (ART) cause many embryos not to survive to birth. We have shown that IVF causes increased expression of protein normally involved in stopping cells from dividing. This is a major cause of embryo death after IVF. This project will determine how this protein acts to cause embryonic death and assess strategies to prevent it.
Macrophages In Developmental Programming Of Reproductive Health

Summary
Programming of reproductive health in women begins long before sexual maturity. Development during childhood, puberty and adulthood produces a fully functional reproductive system capable of conceiving, gestating and nurturing a child. This project will investigate the role of immune cells known as macrophages in the reproductive system, and investigate how their disruption might influence developmental programming and have lifetime consequences for the reproductive health of the individual.

Summary
Mammalian eggs grow and develop in fluid filled sacks in the ovary called follicles. These structures nurture the egg for prolonged periods preparing it for ovulation and fertilisation. It has been known for some time that the quality of the follicular environment determines, in part, the developmental potential of the egg. Recent studies in mice have shown that the interaction between the egg and the follicle is in fact a two-way process, and that the egg is able to influence development of the ....Mammalian eggs grow and develop in fluid filled sacks in the ovary called follicles. These structures nurture the egg for prolonged periods preparing it for ovulation and fertilisation. It has been known for some time that the quality of the follicular environment determines, in part, the developmental potential of the egg. Recent studies in mice have shown that the interaction between the egg and the follicle is in fact a two-way process, and that the egg is able to influence development of the follicle. This project proposes to investigate these processes further in the laboratory mouse using new reagents available to us, and to extend these findings by investigating this communication pathway for the first time in a primate species. Because of the difficulty of undertaking such research using human material, we will use the marmoset monkey as a model. This exciting new development has important implications for women's health because it may help us understand why some women suffer from premature menopause or cystic ovaries, and in the longer term could help in the development of new types of contraceptives.Read moreRead less
