The polycystic ovary syndrome (PCOS) is a very common medical condition that has reproductive consequences for a woman with regard to menstrual irregularity and ovulatory disorder. Often women with PCOS require fertility assistance to conceive in the form of ovulation induction treatment. However when a woman with PCOS conceives; she is at greater risk of miscarriage and pregnancy related complications than her peer group. Furthermore in later life a woman with PCOS is prone to the metabolic sequelae of diabetes and cardiovascular disease. This presentation will provide an insight into the influence PCOS on obstetric and perinatal outcomes on women and their children using state-wide data linkage systems within Western Australia. Our data analysis confirms the previous observational data of an increased risk of adverse obstetric outcomes and for the first time reports the implications for the offspring of women with a PCOS diagnosis.
