  • Purpose: To evaluate how follicles develop in the ovaries of overweight women during weight loss, and to explore how changes in body composition, metabolic status, and reproductive hormones influence patterns of ovarian follicle development.
  • We are looking for: Women, ages 18-35 years, with a BMI > 30, who are not currently taking hormones (i.e., birth control pills, fertility medications, etc.)
  • Time Commitment: 7-months of 2-4 study visits per week (20 minutes each) including a blood draw and transvaginal ultrasound scan, plus 3-4 longer visits (~2.5 hours) requiring an overnight fast.
  • Honorarium: $2000, 6-month subscription to Nutrisystem DTM, and a Fitbit™
  • Study Location:  Cornell University (Ithaca, NY)
  • ClinicalTrials.gov ID: NCT01785719
  • Purpose: To compare how follicles develop in the ovaries of women that have regular menstrual cycles and those that have irregular/absent menstrual cycles, and to explore how body composition, metabolic status, and reproductive hormones are related to patterns of follicle development.
  • We are looking for: Women, ages 18-35 years, with a BMI < 25, who are not currently taking hormones (i.e., birth control pills, fertility medications, etc.)
  • Time Commitment: 4-5 weeks of every-other-day study visits (20 minutes each), including a blood draw and transvaginal ultrasound scan, plus one longer visit (~2.5 hours) requiring an overnight fast.
  • Study Location:  Cornell University (Ithaca, NY)
  • Honorarium: $300
  • ClinicalTrials.gov ID: NCT01927432
  • Purpose: To evaluate how aspects of metabolism, lifestyle, and age influence ovarian function, as well as how hormones differ in women with distinct patterns of follicle populations.
  • We are looking for: Women, ages 18 - 48 years, with irregular periods and excess male-pattern hair growth and/or a previous diagnosis of PCOS and a BMI < 25, who are not currently taking hormones (i.e., birth control pills, fertility medications, etc.
  • Time Commitment: 3.5 - 4 hours spread over 3 study visits, 7 days off site (to wear a device that measures physical activity).
  • Study Location: Cornell University (Ithaca, NY)
  • Honorarium: $100
  • ClinicalTrials.gov ID: NCT01927471
  • Purpose: To evaluate how aspects of metabolism and lifestyle, including sleep quality and melatonin, are related to ovarian function in women with and without PCOS.
  • We are looking for: Women, ages 18 - 38 years, with regular cycles or a previous diagnosis of PCOS, who are not currently taking hormones (i.e., birth control pills, fertility medications, etc.)
  • Time Commitment: 3.5 - 4 hours spread over 3 study visits, 7 days off site (to wear a device that measures physical activity and sleep, and to perform at-home urine collection).
  • Study Location: Cornell University (Ithaca, NY)
  • Honorarium: $125
  • ClinicalTrials.gov ID: NCT01859663
  • Purpose: This study investigates ultrasound technology and aspects of age and adiposity influence ovarian morphology.
  • We are looking for: Women, ages 18 - 45 years, with regular menstrual cycles, irregular menstrual cycles, or a previous diagnosis of polycystic ovary syndrome (PCOS), who are not currently taking hormones (i.e., birth control pills, fertility medications, etc.)
  • Time Commitment: 45-60 minutes
  • Study Locations: Cornell University (Ithaca, NY) and University of Rochester & Strong Fertility (Rochester, NY)
  • Honorarium: $25
  • ClinicalTrials.gov ID: NCT03547453
  • Ultrasonographic Evaluation of Anovulatory Disorders in Lean and Overweight Women
  • Purpose: The study investigates whether ultrasound features of the ovaries can be used to reliably diagnose different types of anovulatory disorders in women across all body types. The study will also try to establish whether ultrasound features of the ovary can reflect the degree of reproductive and metabolic problems that a woman with irregular or absent periods might be experiencing.
  • We are looking for: Women, ages 18-45 years with regular menstrual cycles, irregular menstrual cycles, or a previous diagnosis of PCOS
  • Time Commitment: 3.5 - 4 hours spread over 4 on-site study visits, 7 days off-site (to wear a device that measures physical activity).
  • Study Location: Weill Cornell, NYC
  • Honorarium: $125
  • ClinicalTrials.gov ID: NCT03306849
