In this study, the researchers are trying to learn more about the relationship between Polycystic Ovary Syndrome and Obstructive Sleep Apnea (OSA). Obstructive Sleep Apnea is a sleep-related breathing disorder that involves a decrease or complete stop in airflow. The purpose of this study is to find out why some people with obstructive sleep apnea have higher levels of insulin resistance, and the investigators will study the role of hypoxia (low levels of oxygen in the blood at night) in insulin resistance and see if insulin resistance improves during your treatment with CPAP.

Number of participants showing a change in fractional de novo lipogenesis (DNL, %)
The percent of newly synthesized fatty acids (DNL, %) will be measured using a stable isotope (deuterated water) and mass spectrometry.
Baseline and 12 weeks
Number of participants showing a change in free testosterone (pg/mL)
The aim is evaluate the effect of treating OSA with CPAP on biochemical hyperandrogenism in individuals with PCOS.
Baseline and 12 weeks
Number of participants showing a change in insulin secretion rate (picomol/min)
Glucose Tolerance Test is used to measure of insulin secretion rate.
Baseline and 12 weeks
Participants randomized to CPAP will initiate CPAP therapy at the beginning of the study.
Participants randomized to delayed CPAP (waitlist control) will initiate CPAP therapy immediately after 12 weeks. The investigators recognize that adherence to CPAP therapy is a common barrier to effective clinical treatment of OSA and to rigorous research on CPAP and has been significantly correlated with improvements in insulin resistance, including in a small of study of women with PCOS. After receiving this device, participants can meet with a study psychiatrist and his team within 3 days of initiating CPAP therapy and as needed for up to a month after initiating therapy. No visits in this time period will be billed to insurance.
Metabolic studies will be performed before and after initiation of CPAP therapy, which is currently the first-line standard of care for treatment of patients with OSA, both with and without hypoxia.
Metabolic studies will be performed before and after the study period of 12 weeks. After 12 weeks, participants will immediate receive CPAP therapy, which is currently the first-line standard of care for treatment of patients with OSA, both with and without hypoxia.
