An observational study in Sleep Apnea, Obstructive, Anovulation and Polycystic Ovarian Syndrome, sponsored by University of Louisville. Withdrawn at 1 site in United States. Open to female participants aged 18 Years to 35 Years. Per ClinicalTrials.gov, last updated 2018-08-03.
Sponsored by University of Louisville · Observational
The purpose of this study is to determine if treatment of obstructive sleep apnea (OSA) with continuous positive airway pressure in women with both OSA and polycystic ovarian syndrome will improve the regularity of the women's menstrual cycles.
Women seeking fertility treatment at the University of Louisville will be screened for polycystic ovarian syndrome (PCOS) based on history and then blood work if history suggests PCOS. After establishing a diagnosis of PCOS based on the National Institute of Health criteria, they will be screened for impaired glucose tolerance, Class III obesity, and obstructive sleep apnea [using the Epworth Sleepiness Scale (ESS) as the initial screen]. For those women that screen positive on the ESS, they will be referred to the University of Louisville Physicians Sleep Center for a formal sleep study. Only patients with PCOS, severe obstructive sleep apnea, impaired glucose tolerance, and Class III obesity will qualify for enrollment in the study. Once enrolled, patients will be encouraged to use continuous positive airway pressure (CPAP, standard of care for treatment of obstructive sleep apnea) for at least six months. During those six months, patients will be asked to track their menstrual cycles and whether they took progesterone to induce a withdrawal bleed during that time period. The use of ovulation predictor kits to help determine ovulation status will be encouraged, but not required for the study.
During initial evaluation, patients seeking fertility care having a clinical presentation concerning for PCOS have their blood drawn for evaluation of thyroid stimulating hormone, free and total testosterone, antimullerian hormone, and 2 hour glucose tolerance test. At the conclusion of six months of CPAP therapy, patients will be asked to repeat the above blood tests for comparison to baseline values.
Women can continue to attempt pregnancy during the study time period if they desire.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.
What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.
Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.
Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.
