To evaluate pregnancy outcomes in women with PCOS we studied a single pregnancy in 46 women with PCOS using 46 controls matched for maternal age, ethnicity and parity. Cases were identified from a laboratory database. The entry criterion for the study was a free androgen index (testosterone/SHBG x100) of 8 or more in symptomatic women investigated in an endocrinology and/or gynaecology clinic. Outcomes studied were pregnancy induced hypertension (PIH, blood pressure > 140/90 on two occasions), impaired glucose tolerance (2h glucose >7.8 mmol/l;75g glucose load) and pre-term labour (<37 weeks). For the infant, birth weight, admission to SCBU and need for resuscitation were recorded. Birth weight in the PCOS group was not significantly different to controls (3511g vs 3350g; p=0.202), neither were macrosomic infants (birth weight >4000g) more common (21.1 % vs 6.5%; p=0.059). PCOS women had more PIH (34.8% vs 8.7%: p=0.005), impaired glucose tolerance (15.2% vs 0 p=0.012) and pre-term labour (17.4% vs 0; p=0.006). PCOS infants required more SCBU admissions (26.7% vs 2.2 %; p=0.002), and resuscitation (53.3% vs 19.6%; p=0.002). In obese PCOS (BMI>30) PIH was more common (65% vs 6.3%) than in non-obese PCOS as was impaired glucose tolerance (30% vs 0; p=0.024) and pre-term labour (37.5% vs 5%; p=0.030). Birth weight was higher in obese than in non-obese PCOS (3774 vs 3186g; p=0.024). There were no differences in SCBU admission 37.5% vs 16 % (p=0.25), or requirement for resuscitation (62.5% vs 52.6%; p=1.0). These results demonstrate that pregnancy complications are more frequent in women with PCOS and indicate that joint protocols between subfertility and obstetric units should be developed for their management.
