There is evidence that PCOS patients had a larger birthweight and were products of pregnancies in which their mother had gestational diabetes. It is clear that the risk of gestational diabetes and probably, pregnancy induced hypertension (PIH, toxemia, preeclampsia) is increased in pregnant women with PCOS. Some of this risk may be independently related to increased pre-pregnancy weight. There is no evidence that babies born of PCOS mothers, or the mothers themselves have any long term complications. Often pregnancies are achieved in the early reproductive years without medical assistance. Pregnancy has a positive health benefit on breast and reproductive cancer. Spontaneous pregnancy sometimes follows a pregnancy that was achieved after a prolonged wait, or aggressive fertility therapy.
